Abstract
PAHs and BTEX were studied in groundwater from monitoring wells of gasoline stations of Rio de Janeiro City, Brazil during 2003 and 2004. Total PAH concentration ranged from 0.05 to 84.9 microg/L. Total BTEX concentration varied between not-detected to 3.6 x 10(3) microg/L. Some samples exceeded the maximum concentration limit of Brazilian regulations for benzene in fresh or drinking water. Carcinogenic PAHs were found in few samples but only one sample in each year exceeded the regulated concentrations for benzo[a]pyrene. The concentrations of PAHs and BTEX indicate that some places may be contaminated by gasoline leakage.Entities:
