Health effects of ambient particulate matter--biological mechanisms and inflammatory responses to in vitro and in vivo particle exposures.

abstract：:Halomethanes (HMs) can be formed during the chlorination process to obtain drinking water. In liver cells, HMs had been shown to be mutagenic and carcinogenic; however, their bioactivation by CYP 2E1 and GSTT1 is required. Although inhalation is the most common pathway of exposure, reports on the toxic effects induced...
