Alkylphenol polyethoxylate derivatives in groundwater and blood samples collected from pig herds in Taiwan.
Alkylphenol polyethoxylate (APEO) derivatives, such as nonylphenol monoethoxylate (NP1EO), nonylphenol diethoxylate (NP2EO), nonylphenol (NP) and octylphenol (OP), have been detected in the surface water, sediment, food and groundwater of numerous countries. Because groundwater is the main source of water for pig herds, the aim of this study was to measure the concentrations of APEO derivatives in groundwater and blood samples that were collected from pig herds raised near the Wuluo River in Southern Taiwan. The mean concentrations of NP, OP, NP1EO and NP2EO in the groundwater supply for 10 pig herds were 0.04 µg/l, 0.26 ± 0.23 µg/l, 0.74 ± 0.69 µg/l and 0.17 ± 0.22 µg/l, respectively. NP was detected in all blood samples collected from 5 of the 10 pig herds. The highest concentrations detected in the blood samples collected from six-week-old piglets and sows were 12.00 µg/l and 56.94 µg/l, respectively. Blood samples from 4 of the 5 herds showed OP contamination. The highest OP concentrations detected in 6-week-old piglets and sows were 275.58 µg/l and 566.32 µg/l, respectively. These results indicate that APEO derivatives accumulated in the groundwater supply and the bloodstreams of the pigs.
