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. g/m 3 or less.
Heavy-duty trucks can emit drastically higher levels of pollution when not equipped with required emissions controls. Transport companies must comply with California’s rule to improve air quality and protect adjacent schools and communities from breathing these toxic pollutants. The company, headquartered in Thomasville, N.C.,
I recently read a brilliant book, Malcolm Gladwells, Revenge of the Tipping Point that alerted me to the fact that just five per cent of the passenger vehicles on the road produce more than half of all the pollution in the air. Pollution would drop by the same amount as the 10 per cent shift. Ford Falcon.
in 2030 even if India were to comply with its existing pollution control policies and regulations.
