| a risk assessment of atrazine use in california: human health and ecological aspects. | a risk assessment of the triazine herbicide atrazine has been conducted by first analyzing the toxicity database and subsequently estimating exposure. margins of safety (mos) were then calculated. toxicity was assessed in animal studies and exposure was estimated from occupational and dietary sources. in acute toxicity studies, atrazine caused developmental toxicity in the rabbit [no observed effect level (noel) 5 mg kg(-1) day(-1)] and cardiotoxicity in a dog chronic study (noel 0.5 mg kg(-1) d ... | 2005 | 15655806 |
| in vitro genotoxicity of exhaust emissions of diesel and gasoline engine vehicles operated on a unified driving cycle. | acetone extracts of engine exhaust particulate matter (pm) and of vapor-phase semi-volatile organic compounds (svocs) collected from a set of 1998-2000 model year normal emitter diesel engine automobile or light trucks and from a set of 1982-1996 normal emitter gasoline engine automobiles or light trucks operated on the california unified driving cycle at 22 [degree]c were assayed for in vitro genotoxic activities. gasoline and diesel pm were comparably positive mutagens for salmonella typhimuri ... | 2004 | 15614403 |
