Tire Dust Makes Up the Majority of Ocean Microplastics, Study Finds<\/a><\/h3>\n

Researchers say tire emissions pose a threat to global health, and EVs could make the problem worse.<\/strong><\/p>\n<\/div>\n<\/div>\n

When contemplating the\u00a0emissions<\/a>\u00a0from road vehicles, our first thought is often about the various gases coming out of the tailpipe. However, new research shows that we should be more concerned with the harmful particles that are shed from\u00a0tires<\/a>\u00a0and\u00a0brakes<\/a>.<\/p>\n<\/div>\n

\n

Scientists have a good understanding of engine emissions, which typically consist of unburnt fuel, oxides of carbon and nitrogen, and particulate matter related to combustion. However, new research shared by\u00a0Yale Environment 360<\/a><\/em>\u00a0indicates that there may be a whole host of toxic chemicals being shed from tires and brakes that have been largely ignored until now. Even worse, these emissions may be so significant that they actually exceed those from a typical car’s exhaust output.<\/p>\n<\/div>\n

\n

A research paper published\u00a0in 2020<\/a>\u00a0highlighted the impact of tire pollution by examining the plight of coho salmon in West Coast streams. Scientists eventually identified a chemical called 6PPD, typically used in tire manufacturing to slow cracking and degradation. When exposed to ozone in the atmosphere, the chemical transforms into multiple other species, including 6PPD-quinone\u2014which was found to be highly toxic to multiple fish, including coho salmon. The same chemical has since been detected\u00a0in human urine<\/a>, though any potential health impacts remain unknown.<\/p>\n<\/div>\n

\n

The discovery of 6PPD-q and its impact has brought new scrutiny to the pollution generated by particles shedding from tires and brakes. In particular, tire rubber is made up of over 400 different chemical compounds, many of which are known to have negative effects on human health.<\/p>\n<\/div>\n

Particulate emissions from tires\u2014and, to a lesser extent, brakes\u2014are becoming a new focus for researchers looking into automobile pollution.<\/p><\/div>\n
