Benzo(a)pyrene and bisphenol A have been classified as endocrine disrupting chemicals (EDCs), which have been of concern in toxicology and environmental sciences. Benzo(a)pyrene and bisphenol A were monitored by HPLC or GC-MS in Baekwoon and Ilwirl lakes of Kyonggi-Do province to investigate contamination levels of EDCs. During the period between June, 2000 and August, 2000, water samples were collected from four different sites of each lake once per month. Contamination levels of benzo(a)pyrene were 3.27~4.25 ppb in Ilwirl lake and 2.00~2.33 ppb in Baekwoon lake, respectively. Bisphenol A levels were detected with the range of 0.33~7.94 and 0.43~4.71 for Baekwoon lake and Ilwirl lake, respectively. pH levels were higher in Ilwirl lake than in Baekwoon lake, where the contamination was relatively lower. These data suggest that lakes in Kyonggi-Do province could be contaminated with EDCs and be subjected to the routine monitoring and water quality control.
