Bisphenol A occurred in Kao-Pin River and its tributaries in Taiwan.
Bisphenol A (BPA), one of the endocrine-disrupting chemicals, was detected in water collected from Kao-Pin River and its tributaries. Results indicated that 59% of the water samples contained BPA. Concentrations ranged from less than the limit of detection (LOD, 0.037) to 4.23 microg/L. The mean concentrations were 0.16, 0.20, 1.02, 1.30, and 0.30 microg/L for sampling sites S1, S2, S3, S4, and S5, respectively. Concentrations were not significantly different between high and low-flow periods in sites S2, S3, and S4. In site S1, concentrations in the high-flow period were significantly greater than during the lower flow period, and in site S5, BPA concentration in the low-flow period was significantly greater than in the high-flow period. The BPA mass flow rate in site S5 was greater in the high-flow period than in the low-flow period.
