PM2 5 polluters disproportionately and systemically affect people of color in the United States

Abstract Racial-ethnic minorities in the United States are exposed to disproportionately high levels of ambient fine particulate air pollution (PM 2.5), the largest environmental cause of human mortality. However, it is unknown which emission sources drive this disparity and whether differences exist by emission sector, geography, or demographics. Quantifying the PM 2.5 exposure caused by each emitter type, we show that nearly all major emission categories consistently across states, urban and rural areas, income levels, and exposure levels contribute to the systemic PM 2.5 exposure disparity experienced by people of color. We identify the most inequitable emission source types by state and city, thereby highlighting potential opportunities for addressing this persistent environmental inequity.

Black Americans have disproportionately suffered from pollution It s time for a new policy

Black Americans have disproportionately suffered from pollution. It’s time for a new policy. Vox.com 2/26/2021 Rachel Ramirez © Julie Dermansky for Vox Environmental justice activist Sharon Lavigne stands outside her home in St. James, Louisiana, on February 23, 2021. Sharon Lavigne has lived in St. James Parish, Louisiana, a predominantly Black community, all her life. She remembers when the air wasn’t covered with thick gray smog, when the water was still safe to drink, when the gardens were productive and fertile. But now, she says, “we are sick and we are dying.” Lavigne has watched her neighbors die from cancer and suffer from respiratory illnesses. About five years ago, she too was diagnosed with pollution-linked autoimmune hepatitis, with tests showing she had aluminum inside her body. The reason for the community’s decline in health, environmentalists say, is a burgeoning fossil fuel industry right in their backyards.
