NEW YORK, Dec 16 — Remnants of industrial chemicals in the air can potentially transform into new substances more toxic and persistent than the original pollution, according to a global study published yesterday.found that these previously unidentified products are present in the atmospheres of 18 big cities including Lagos, New York, Tokyo and Warsaw.
The research proposes a new framework using laboratory tests and computer simulation to predict what chemicals will arise as products interact with the air and how toxic they will be. In a laboratory, they observed how these chemicals changed over time when in contact with oxidants in the air and found that they gave rise to 186 different substances.
They discovered that the new chemicals could have longer-lasting impacts on the environment and could be more toxic than their parent chemicals — in some cases 10 times as much.
