Evaluation of atmospheric particulate matter from an industrial area in Southeast Brazil

Autor: Aparecida M S, Mimura, Cássia C M, Ferreira, Júlio C J, Silva

Publikováno v: Environmental monitoring and assessment. 192(12)

A large number of pollutants, such as trace elements, can be found on the surface of atmospheric particulate matter. Since some trace elements can be hazardous to humans, monitoring the atmospheric emissions is relevant to generate comparative data o
