So, yesterday an Iranian missile hit a chemical plant in southern Israel.

The plant belongs to a company called ADAMA, and they had to issue a hazardous materials warning for the surrounding area.

And I looked at this story and thought, okay, there's a lot more going on here than a headline.

Octavio ES

Bueno, mira, lo primero que hay que entender es qué es exactamente ese complejo.

Well, look, the first thing to understand is what exactly that complex is.

ADAMA, que antes se llamaba Makhteshim Agan, es una de las empresas agroquímicas más grandes del mundo.

ADAMA, formerly known as Makhteshim Agan, is one of the largest agrochemical companies in the world.

Produce herbicidas, fungicidas, insecticidas.

It produces herbicides, fungicides, insecticides.

Materiales que son esenciales para la agricultura global, pero que también pueden ser extremadamente peligrosos si se liberan de manera incontrolada.

Materials that are essential for global agriculture, but which can also be extremely dangerous if released in an uncontrolled way.

Fletcher EN

Right, so this isn't just any factory.

ADAMA is actually the fourth or fifth largest agrochemical company on the planet.

They operate in something like 100 countries.

And the Negev plant, the one that was hit, is one of their main manufacturing sites.

Octavio ES

Exacto.

Exactly.

Y la pregunta científica clave aquí es: ¿qué se fabrica en esa planta?

And the key scientific question here is: what is manufactured in that plant?

Porque los agroquímicos no son todos iguales.

Because agrochemicals are not all the same.

Algunos son relativamente inofensivos a bajas concentraciones.

Some are relatively harmless at low concentrations.

Otros, como ciertos compuestos organofosforados, son tóxicos en cantidades muy pequeñas y tienen una historia bastante oscura que va mucho más allá de los campos de cultivo.

Others, like certain organophosphate compounds, are toxic in very small quantities and have a rather dark history that goes far beyond agricultural fields.

Fletcher EN

Here's what gets me about that.

Organophosphates.

You say the word and most people think pesticides.

But the connection between agricultural chemistry and chemical weapons is not accidental.

It's the same basic molecular family.

Octavio ES

Es que eso es precisamente lo que hace que esta historia sea tan inquietante desde el punto de vista científico.

That is precisely what makes this story so unsettling from a scientific point of view.

Los organofosforados fueron desarrollados originalmente en Alemania en los años treinta y cuarenta, y los primeros compuestos que se sintetizaron no eran plaguicidas agrícolas sino agentes nerviosos militares, el tabún y el sarín.

Organophosphates were originally developed in Germany in the 1930s and 1940s, and the first compounds synthesized were not agricultural pesticides but military nerve agents, tabun and sarin.

La transición hacia usos civiles vino después.

The transition to civilian uses came later.

Fletcher EN

The same chemist, Gerhard Schrader, essentially invented both.

He was trying to make a better insecticide and stumbled onto the most lethal class of chemicals ever synthesized.

The same inhibition mechanism that kills an aphid, at higher concentrations, shuts down the human nervous system.

Octavio ES

Bueno, y eso nos lleva directamente al problema de atacar una planta como la de ADAMA.

Right, and that takes us directly to the problem of striking a plant like ADAMA's.

No estamos hablando de que un misil golpee un almacén de cereales.

We're not talking about a missile hitting a grain warehouse.

Estamos hablando de instalaciones donde se sintetizan, almacenan y procesan compuestos cuya toxicidad puede ser brutal.

We're talking about facilities where compounds are synthesized, stored, and processed, compounds whose toxicity can be devastating.

Un incendio en ese contexto no es un incendio ordinario: genera humos que pueden ser letales dependiendo de qué se esté quemando.

A fire in that context is not an ordinary fire: it generates fumes that can be lethal depending on what is burning.

Fletcher EN

And this isn't a new problem.

Look, the history of industrial sites becoming military targets is long and really grim.

I want to go back, because context matters here.

Octavio ES

A ver, el precedente histórico más obvio es la Segunda Guerra Mundial.

Well, the most obvious historical precedent is the Second World War.

Los aliados bombardearon deliberadamente plantas químicas e industriales en Alemania, especialmente las instalaciones de IG Farben, que producía tanto explosivos como el Zyklon B.

The Allies deliberately bombed chemical and industrial plants in Germany, especially the IG Farben facilities, which produced both explosives and Zyklon B.

El razonamiento estratégico era claro: destruir la capacidad industrial del enemigo.

The strategic reasoning was clear: destroy the enemy's industrial capacity.

Pero las consecuencias ambientales y sanitarias para las poblaciones civiles cercanas eran devastadoras.

But the environmental and health consequences for nearby civilian populations were devastating.

Fletcher EN

And then Yugoslavia.

I think a lot of people have forgotten this but when NATO bombed Serbia in 1999, they hit the Pancevo petrochemical complex outside Belgrade.

It released vinyl chloride, mercury, dioxins into the Danube and into the atmosphere.

The UN environment program called it one of the worst environmental disasters in European history.

Octavio ES

Y lo que ocurrió en Pancevo ilustra algo fundamental: cuando una planta química arde o explota, los contaminantes no respetan fronteras.

And what happened at Pancevo illustrates something fundamental: when a chemical plant burns or explodes, the contaminants do not respect borders.

El cloruro de vinilo que se liberó en Pancevo no se quedó en Serbia;

The vinyl chloride released at Pancevo did not stay in Serbia;

viajó con el viento, contaminó el Danubio, afectó a Rumanía y Bulgaria.

it traveled with the wind, contaminated the Danube, affected Romania and Bulgaria.

La guerra convirtió una instalación industrial en un arma química difusa, sin que nadie la diseñara específicamente para eso.

The war turned an industrial facility into a diffuse chemical weapon, without anyone specifically designing it as one.

Fletcher EN

We saw the same thing more recently in Ukraine.

The Lysychansk oil refinery, the Azot chemical plant in Severodonetsk, which was one of Europe's largest ammonia producers.

When that complex was in the middle of the fighting in 2022, the worry wasn't just about the battle.

It was about what would happen if those tanks of ammonia ruptured.

Octavio ES

El amoníaco es un ejemplo perfecto de por qué esto es tan peligroso.

Ammonia is a perfect example of why this is so dangerous.

Es un gas más denso que el aire, se acumula en zonas bajas, y en concentraciones suficientes destruye el tejido pulmonar en minutos.

It is a gas denser than air, it accumulates in low-lying areas, and in sufficient concentrations it destroys lung tissue within minutes.

La planta de Azot tenía miles de toneladas almacenadas.

The Azot plant had thousands of tons stored.

Si hubiera habido una liberación masiva con viento en la dirección equivocada, estaríamos hablando de un desastre comparable a Bhopal.

If there had been a massive release with the wind in the wrong direction, we would be talking about a disaster comparable to Bhopal.

Fletcher EN

Bhopal.

Right.

1984.

Union Carbide pesticide plant in India.

Methyl isocyanate leak.

Three thousand people dead in the immediate aftermath, estimates of up to twenty thousand from long-term effects.

And that was an accident.

Nobody dropped a missile on it.

Octavio ES

La verdad es que Bhopal sigue siendo el referente que usan los científicos ambientales cuando quieren ilustrar el potencial catastrófico de un accidente en una planta agroquímica.

The truth is that Bhopal remains the reference that environmental scientists use when they want to illustrate the catastrophic potential of an accident at an agrochemical plant.

Y la diferencia crucial con lo que ocurrió ayer en Israel es exactamente la que apuntas: Bhopal fue un fallo técnico.

And the crucial difference with what happened yesterday in Israel is exactly the one you point out: Bhopal was a technical failure.

Lo de ADAMA fue deliberado.

The ADAMA strike was deliberate.

Eso cambia el análisis legal y moral por completo.

That completely changes the legal and moral analysis.

Fletcher EN

So let's talk about that legal dimension.

Because there is actually a body of international humanitarian law that's supposed to protect exactly this kind of facility.

Article 56 of Additional Protocol I to the Geneva Conventions.

Works of containing dangerous forces.

Dams, nuclear plants, chemical facilities.

You're not supposed to target them.

Octavio ES

Mira, el problema con el Protocolo I es doble.

Look, the problem with Protocol I is twofold.

Primero, hay potencias importantes que no lo han ratificado, entre ellas Estados Unidos e Israel.

First, there are important powers that have not ratified it, including the United States and Israel.

Segundo, incluso para los estados que sí lo han ratificado, la protección no es absoluta: se puede atacar una instalación de este tipo si se usa directamente en apoyo de operaciones militares, lo que crea un agujero legal enorme que los abogados militares explotan con entusiasmo.

Second, even for states that have ratified it, the protection is not absolute: a facility of this type can be attacked if it is used directly in support of military operations, which creates an enormous legal loophole that military lawyers exploit with enthusiasm.

Fletcher EN

The extraordinary thing is that even if we set aside the legal question entirely, the scientific logic should be enough to make states think twice.

Because here is the thing about chemical contamination, it doesn't end when the war ends.

Octavio ES

Eso es absolutamente central.

That is absolutely central.

Los compuestos organofosforados, por ejemplo, pueden degradarse en el suelo en semanas o en meses dependiendo de las condiciones ambientales, pero otros contaminantes industriales, como los metales pesados o los compuestos organoclorados, persisten durante décadas.

Organophosphate compounds, for example, can degrade in soil within weeks or months depending on environmental conditions, but other industrial contaminants, such as heavy metals or organochlorine compounds, persist for decades.

Puedes ganar la guerra y seguir envenenando a tu propia población durante una generación.

You can win the war and still be poisoning your own population for a generation.

Fletcher EN

I mean, the Negev location specifically.

Southern Israel.

Arid climate.

What does that do to the dispersal dynamics?

Because I'm thinking about how contamination behaves differently in a desert environment versus, say, the Rhine valley.

Octavio ES

Es una pregunta muy buena.

That is a very good question.

En un entorno árido, la dispersión atmosférica puede ser en realidad más rápida porque hay menos vegetación que absorba o filtre los contaminantes.

In an arid environment, atmospheric dispersal can actually be faster because there is less vegetation to absorb or filter the contaminants.

Pero el problema subterráneo es diferente: los acuíferos en zonas áridas son extremadamente vulnerables porque la capacidad de autodepuración del suelo es menor.

But the underground problem is different: aquifers in arid zones are extremely vulnerable because the soil's self-purifying capacity is lower.

Si hay filtración hacia el agua subterránea, las consecuencias pueden ser duraderas y difíciles de remediar.

If there is leakage into groundwater, the consequences can be long-lasting and difficult to remediate.

Fletcher EN

And Israel's aquifers are already under pressure.

The Mountain Aquifer, the Coastal Aquifer, these are shared resources between Israel and the Palestinian territories.

So a contamination event from a chemical plant in the Negev is not geographically neutral.

Octavio ES

Exacto, y eso introduce una dimensión geopolítica que va más allá de la guerra inmediata.

Exactly, and that introduces a geopolitical dimension that goes beyond the immediate war.

La contaminación hídrica no entiende de fronteras ni de acuerdos de armisticio.

Water contamination does not understand borders or armistice agreements.

Es que este es el tipo de daño colateral que puede seguir generando conflictos mucho después de que los misiles dejen de caer.

This is precisely the kind of collateral damage that can continue generating conflicts long after the missiles stop falling.

Fletcher EN

Look, there's a concept in military theory called CBRN, Chemical, Biological, Radiological, Nuclear.

And the concern for decades has been that a non-state actor might acquire these capabilities.

But what we're watching now is something almost more insidious, which is the deliberate weaponization of civilian industrial infrastructure.

Octavio ES

Bueno, algunos analistas militares llevan años advirtiendo de esto.

Well, some military analysts have been warning about this for years.

No necesitas fabricar un agente nervioso si puedes destruir una planta que fabrica precursores de pesticidas y lograr un efecto tóxico similar con mucho menos esfuerzo técnico y con plena negabilidad, porque oficialmente solo estás atacando infraestructura industrial del adversario.

You do not need to manufacture a nerve agent if you can destroy a plant that manufactures pesticide precursors and achieve a similar toxic effect with far less technical effort and with full deniability, because officially you are only attacking the adversary's industrial infrastructure.

Fletcher EN

Right, so you get a chemical weapons effect without technically deploying a chemical weapon.

And that's a distinction that might matter legally but doesn't matter much to the people downwind.

Octavio ES

La verdad es que la Convención sobre Armas Químicas de 1993 prohíbe el uso de sustancias químicas como método de guerra, pero no aborda explícitamente la destrucción deliberada de plantas civiles que producen esas mismas sustancias.

The truth is that the 1993 Chemical Weapons Convention prohibits the use of chemical substances as a method of warfare, but does not explicitly address the deliberate destruction of civilian plants that produce those same substances.

Es una laguna legal que refleja los límites de los tratados negociados en una época en que este tipo de ataques no era una táctica tan evidente.

It is a legal gap that reflects the limitations of treaties negotiated at a time when this type of attack was not such an obvious tactic.

Fletcher EN

I want to bring in the nuclear parallel, because it feels directly relevant.

Zaporizhzhia.

The largest nuclear power plant in Europe, in the middle of a war zone, occupied by Russian forces, shelled periodically.

The International Atomic Energy Agency there trying to monitor the situation.

The world watching and not quite knowing what to do.

Octavio ES

No, no, espera, porque el paralelo con Zaporizhzhia es muy certero pero tiene una diferencia importante.

No, no, wait, because the parallel with Zaporizhzhia is very apt but there is an important difference.

En Ucrania existía al menos una estructura de monitoreo internacional, la AIEA tenía presencia física.

In Ukraine there was at least an international monitoring structure, the IAEA had a physical presence.

En el caso de una planta agroquímica como la de ADAMA, no hay ningún organismo internacional con mandato para supervisar lo que ocurre.

In the case of an agrochemical plant like ADAMA's, there is no international body with a mandate to oversee what happens.

La transparencia sobre lo que se ha liberado depende enteramente de las autoridades israelíes.

Transparency about what has been released depends entirely on the Israeli authorities.

Fletcher EN

And that's a problem.

Because in these situations, the affected population needs independent verification.

Not because you assume bad faith, but because industrial accidents and industrial attacks generate confusion, and authorities have institutional incentives to minimize reported impacts.

Octavio ES

A ver, la ciencia de la detección ha avanzado enormemente.

Well, the science of detection has advanced enormously.

Hoy existe tecnología de espectrometría de masas portátil que puede identificar compuestos orgánicos volátiles en el aire en tiempo real.

Today there is portable mass spectrometry technology that can identify volatile organic compounds in the air in real time.

Hay satélites con sensores que pueden detectar plumas de contaminación atmosférica.

There are satellites with sensors that can detect atmospheric contamination plumes.

La pregunta no es si podemos medir lo que se ha liberado, sino quién tiene acceso a esos datos y quién los interpreta.

The question is not whether we can measure what has been released, but who has access to that data and who interprets it.

Fletcher EN

The extraordinary thing about modern conflict is that you now have this layer of scientific monitoring capacity that can, in theory, document everything.

The OPCW used it in Salisbury.

They used it in Douma.

But the political will to act on that information is a completely separate question.

Octavio ES

Es que ahí está el nudo del problema.

That is precisely the core of the problem.

La ciencia puede documentar;

Science can document;

el derecho internacional puede, en teoría, atribuir responsabilidad;

international law can, in theory, attribute responsibility;

pero el mecanismo de aplicación real es casi inexistente cuando las grandes potencias están implicadas directa o indirectamente.

but the actual enforcement mechanism is almost nonexistent when major powers are directly or indirectly involved.

Lo que ayer ocurrió en el Néguev no va a llegar a ningún tribunal en ningún plazo previsible.

What happened yesterday in the Negev is not going to reach any court within any foreseeable timeframe.

Fletcher EN

So let me ask you the harder question.

Is this a turning point, or is it just another data point in a long, depressing pattern?

Because I've been watching industrial sites get targeted in conflicts since the nineties, and the line seems to keep getting crossed without consequence.

Octavio ES

Mira, creo que es ambas cosas, y eso es lo que lo hace especialmente preocupante.

Look, I think it is both, and that is what makes it especially worrying.

Es otro punto en una tendencia consolidada, sí.

It is another point in an established trend, yes.

Pero también es un precedente en un conflicto de alta visibilidad que otros actores están observando con mucha atención.

But it is also a precedent in a high-visibility conflict that other actors are watching very closely.

Cada vez que se ataca una planta química sin consecuencias serias, se normaliza la táctica.

Every time a chemical plant is attacked without serious consequences, the tactic is normalized.

Y la normalización en el ámbito militar tiene consecuencias que se despliegan durante décadas.

And normalization in the military sphere has consequences that unfold over decades.

Fletcher EN

No, you're absolutely right about that.

And there's a science communication failure here too.

Because when you say an Iranian missile hit a chemical plant, most listeners picture an explosion and some smoke.

They don't picture the soil contamination, the groundwater risk, the long-term health surveillance that a community needs for the next twenty years.

Octavio ES

La verdad es que la comunicación científica en contextos de guerra es casi imposible.

The truth is that scientific communication in wartime contexts is almost impossible.

Cuando hay misiles cayendo, la gente no quiere escuchar explicaciones sobre la toxicocinética de los compuestos organofosforados.

When missiles are falling, people do not want to hear explanations about the toxicokinetics of organophosphate compounds.

Quiere saber si tiene que evacuar ahora mismo.

They want to know if they need to evacuate right now.

Y la tensión entre la urgencia de la comunicación de emergencia y la complejidad de la información científica es uno de los problemas más difíciles de resolver en este ámbito.

And the tension between the urgency of emergency communication and the complexity of scientific information is one of the most difficult problems to resolve in this field.

Fletcher EN

I spent time in Beirut in 2006 during the war, and I remember covering the Jiyeh power plant fire, the fuel spill into the Mediterranean.

At the time it was a side story.

Forty million liters of oil.

It contaminated coastline from Lebanon to Turkey.

The war got all the attention.

The environmental catastrophe ran for years.

Octavio ES

El derrame de Jiyeh es un caso de estudio clásico en ecología del conflicto.

The Jiyeh spill is a classic case study in conflict ecology.

Y lo que ilustra es que los daños ambientales de la guerra tienen un ritmo temporal completamente diferente al del conflicto armado.

And what it illustrates is that the environmental damage from war has a completely different temporal rhythm from that of the armed conflict.

La guerra puede durar semanas;

The war may last weeks;

la recuperación ecológica puede tardar lustros.

ecological recovery may take decades.

Y ese desajuste temporal hace que los daños ambientales queden sistemáticamente infravalorados en los análisis de coste del conflicto.

And that temporal mismatch means that environmental damage is systematically undervalued in analyses of the cost of conflict.

Fletcher EN

So when we hear that Israel issued a hazardous materials warning for the vicinity of the ADAMA plant, that's the beginning of a story, not the end of one.

The warning is the acute phase.

What comes next, the monitoring, the soil testing, the health surveillance of local communities, that's the chapter nobody writes.

Octavio ES

Y eso conecta con algo más profundo sobre cómo documentamos los conflictos.

And that connects to something deeper about how we document conflicts.

Los periodistas cubrimos las explosiones, los diplomáticos negocian los altos al fuego, pero los epidemiólogos y los geoquímicos que llegan después, cuando ya no hay cámaras, son los que realmente miden el coste completo de lo que ocurrió.

Journalists cover the explosions, diplomats negotiate the ceasefires, but the epidemiologists and geochemists who arrive afterward, when the cameras are gone, are the ones who truly measure the full cost of what happened.

Su trabajo es silencioso, lento y esencial, y casi nunca se convierte en titular.

Their work is silent, slow, and essential, and it almost never becomes a headline.

Fletcher EN

That's a good place to leave it, I think.

The missile hit a plant.

The warning went out.

And somewhere in southern Israel right now, there are scientists with equipment trying to figure out exactly what is in the air and the soil.

That work matters.

It's going to matter long after this conflict ends.

Octavio ES

Bueno, y para los que escucháis esto y queréis seguir profundizando: buscad los informes del PNUMA, el Programa de las Naciones Unidas para el Medio Ambiente, sobre los conflictos de los Balcanes y de Líbano.

Well, and for those of you listening who want to dig deeper: look up the reports from UNEP, the United Nations Environment Programme, on the Balkans and Lebanon conflicts.

Son documentos técnicos pero accesibles, y os van a cambiar completamente la manera de leer las noticias de guerra.

They are technical documents but accessible, and they will completely change the way you read war news.

Lo que veis en los titulares es solo la superficie.

What you see in the headlines is only the surface.
