	Petrol inhalation causes road-rage rats http://apocadocs.com/s.pl?1259071572 Breathing in fumes from petrol made lab rats more aggressive, a finding that has wide implications for urban pollution, according to a study published on Tuesday.

Dissection of the rats showed that those exposed to petrol (US gasoline), had big fluctuations in a key group of neurotransmitters -- chemicals used for exchanging messages between neurons -- in three areas of the brain. In addition, rats exposed to unleaded petrol showed indications of neurological change. Their brain cells looked like they had been damaged by rogue molecules called free radicals.
