“…In the US alone, there are approximately 100,000 different sites that have benzene soil or groundwater contamination [1]. Benzene and substituted benzene exposure to humans are widely studied in terms of biochemical markers and molecular toxicology [2][3][4][5][6]. However, little is known about the acute toxicity of benzene and benzene derivatives to aquatic biota.…”

“…Valores similares para frentistas também foram relatados no estudo de Costa e Costa 36 . No entanto, a exposição a benzeno em doses baixas não exclui o risco à saúde 37,38 . De acordo com Smith et al 38 , o mecanismo de ação do benzeno na medula óssea leva aos efeitos tóxicos também em baixos níveis de exposição e podem aumentar gradativamente com doses crescentes e sugere que um modelo em que não exista um limite de exposição segura é o mais apropriado para a exposição ao benzeno.…”

“…O biomonitoramento da população exposta a agentes químicos pelo Teste Cometa, nos últimos anos, tornou-se uma ferramenta importante para detectar efeitos celulares como danos do DNA 5,11,21,17,37 . Embora a detecção de danos no DNA, utilizando linfócitos do sangue periférico, não represente o surgimento de patologias no curto e médio prazo, os especialistas concordam que as células do sangue podem ser usadas como "células-sentinela", a fim de fornecer um sinal de detecção precoce de efeitos adversos à saúde 41 .…”

“…It has long been known that benzene causes leukemia, although there are still some ambiguities regarding its mechanism and concentration-response correlation. Chronic exposure to low benzene concentrations in the workplace is associated with blood diseases like aplastic anemia and leukemia 3 . Benzene, toluene and xylene are key aromatic compounds in gasoline.…”

“…Single breakages of DNA bonds, SCE, MN and CA are reported in the leukocytes of workers who are occupationally exposed to benzene. It is suggested that benzene also plays a role in mutagenesis because of an indirect mechanism that causes oxidative DNA damage by inducing the formation of hydroxyl radicals from hydrogen peroxidase 3 .…”
