Green Car Congress

pollution was significantly associated with an increased risk of hospital admissions for several neurological disorders, including Parkinson’s disease, Alzheimer’s disease, and other dementias, in a long-term study of more than 63 million older US adults, led by researchers at Harvard T.H. Chan School of Public Health.

China-based study concludes using political incentives to fight pollution is costly and inefficient

Green Car Congress

The study looked at water quality regulations and found that local officials more heavily enforced regulations on polluting firms that were monitored and tracked by the central government, while not enforcing regulations on firms not tracked. A 10% reduction in pollution led to a 3% drop in productivity for China’s polluting industries.

Study finds long-term exposure to air pollution negatively impacts cognitive performance and may become more pronounced with age

Green Car Congress

Researchers from China and the US have found that long-term exposure to air pollution impedes cognitive performance in verbal and math tests. Air quality was measured using the air pollution index (API), which is calculated based on daily readings of sulfur dioxide (SO 2 ), nitrogen dioxide (NO 2 ), and particulate matter smaller than 10 ?m

10-year study shows how air pollution fosters heart disease; accelerated plaque build-up in arteries

Green Car Congress

Long-term exposure to particulate air pollution has been linked to an increased risk of heart disease, but the biological process has not been understood. Participant-specific pollutant concentrations averaged over the years 2000–10 ranged from 9.2–22.6 The study is published in The Lancet. and NO x between 1999 and 2012.

Study finds that worldwide SO2 emissions rose between 2000-2005 after decade of decline; China, shipping topped growth

Green Car Congress

Global sulfur dioxide (SO 2 ) emissions peaked in the early 1970s and decreased until 2000, with an increase in recent years due to increased emissions in China, international shipping, and developing countries in general, according to a new analysis appearing in the open access journal Atmospheric Chemistry and Physics.
