Durante décadas, las preocupaciones sobre la contaminación automovilística se han centrado en lo que sale del tubo de escape. Ahora, investigadores y reguladores dicen que se necesita prestar más atención a las emisiones tóxicas de los neumáticos mientras los vehículos circulan por las carreteras. Y primero en la lista de preocupaciones se encuentra un producto químico llamado 6PPD, que se agrega a los neumáticos para que duren más tiempo. Cuando los neumáticos se van desgastando por el roce con el pavimento, liberan 6PPD. Al entrar en contacto con el ozono, esta sustancia reacciona y se convi...

For decades, concerns about automobile pollution have focused on what comes out of the tailpipe. Now, researchers and regulators say, we need to pay more attention to toxic emissions from tires as vehicles roll down the road. At the top of the list of worries is a chemical called 6PPD, which is added to rubber tires to help them last longer. When tires wear on pavement, 6PPD is released. It reacts with ozone to become a different chemical, 6PPD-q, which can be extremely toxic — so much so that it has been linked to repeated fish kills in Washington state. The trouble with tires doesn’t stop th...
