Abstract
The total mercury Hg content of the soft tissues of cultured oysters of the genus Crassostrea obtained during the dry and rainy seasons at sampling sites of NW Mexico with different degrees of urbanization was determined by cold vapor atomic absorption spectrophotometry Hg levels ranged from 005 to 037 µg/g dry weight and no significant differences p 005 related to season and sampling site were observed The values did not exceed the limit of 10 µg/g wet weight established by Mexican legislation and by the Food and Drug Agency FDA and the hazard quotient was between 0001 and 0002 The estimated hazard quotient for MeHg ranged approximately from 0002 to 001
