USC study finds particulate matter in air pollution affects thyroid development in fetuses

Green Car Congress

In a cohort study of a subset of 2050 newborns from the Children’s Health Study in southern California, researchers at the University of Southern California (USC) found that an increase of 2 standard deviations in prenatal exposure to particulate matter in air pollution was associated with higher newborn total thyroxine (TT4) measures.

Study first to quantify amount of US pollution resulting from Chinese manufacturing for exports

Green Car Congress

Average annual percentage of black carbon pollution related to Chinese exports. China is responsible for only a small percentage of the annual pollution in the US, but powerful global winds known as “westerlies” can push airborne chemicals across the ocean in days, particularly during the spring, causing dangerous spikes in contaminants.

Pollution plumes in Paris air are richer in gaseous aromatic compounds than in LA; gasoline engines main source of VOCs

Green Car Congress

The study also shows that the proportion of gaseous aromatic compounds—apart from benzene—in hydrocarbon emissions is two to three times greater in pollution plumes in Paris than in Los Angeles, even though the total quantity of hydrocarbons emitted in Los Angeles remains considerably greater than in Paris.

NOAA, partners find about 98% decline in VOCs concentrations in LA Basin over last 50 years despite 3x increase in use of gasoline and diesel

Green Car Congress

A scatter plot of CO, as a tracer for pollution, versus CO 2 , as a tracer for the amount of combustion, for 2002 and 2010. VOCs, primarily emitted from the tailpipes of vehicles, are a key ingredient in the formation of ground-level ozone which, at high levels, can harm people’s lungs and damage crops and other plants.
