Total arsenic and selenium levels in atmospheric particulate matter of La Coruña (Spain)

This paper presents a study concernin the degree of pollution due to arsenic and selenium in atmospheric particulates of La Coruña (NW Spain). Sampling of particulate matter was accomplished with high volume samplers equipped with glass microfibre filters; samples were collected in two different areas (one an industrial area and the other a rural area). For As and Se determination, hydride generation and electrothermal atomization atomic absorption spectrometry, respectively, were used.
