The Download: toxic chemicals, and Russia’s cyberwar tactics
What are chemical pollutants doing to our bodies? It’s a timely question given that last week, people in Philadelphia cleared grocery shelves of bottled water after a toxic leak from a chemical plant spilled into a tributary of the Delaware River, a source of drinking water for 14 million people. And it was only last month that a train carrying a suite of other hazardous materials derailed in East Palestine, Ohio, unleashing an unknown quantity of toxic chemicals.
There’s no doubt that we are polluting the planet. In order to find out how these pollutants might be affecting our own bodies, we need to work out how we are exposed to them. Which chemicals are we inhaling, eating, and digesting? And how much? The field of exposomics, which seeks to study our exposure to pollutants, among other factors, could help to give us some much-needed answers. Read the full story.
