Chromosome damage induced by carboplatin (CBDCA).

abstract：:Samples of PM(2.5) were gravimetrically collected during the winter 2005/2006 in the urban area of Milan (North Italy). Samples were chemically characterized and the particles were detached from filters to determine their cytotoxic effects on the A549 cell line. Based on the potential toxicological relevance of its co...
