To understand nonylphenol (NP) contamination in the northeast coastal environment in China, NP was determined in 19 sediment and 20 bivalve samples collected during November 2005. NP was identified in all sediment samples in the range of 8.8 to 1.0 x 10(3) ng/g dw (dry weight), with an average of 0.12 x 10(3) ng/g dw. Most of the bivalve samples (oysters and mussels) contained detectable amounts of NP that ranged from ND (not detected) to 7.6 x 10(3) ng/g dw, with an average value of 0.79 x 10(3) ng/g dw. These results indicated that NP is ubiquitous in sediments and bivalves from the northeast coast of China, and are even present in bivalves sold as seafood. Serious contamination with NP was recorded off the coast of Bohai Strait and in semi-enclosed coastal environment such as Jiaozhou Bay and Liaodong Bay. Possible environmental and human health implications were understood in this study.
为了了解中国东北沿海环境中的壬基酚（NP）污染情况，于 2005 年 11 月采集了 19 个沉积物和 20 个双壳贝类样本，对 NP 进行了测定。在所采集的沉积物样本中均检测到 NP，浓度范围为 8.8 至 1.0×10(3)ng/g dw（干重），平均值为 0.12×10(3)ng/g dw。大部分双壳贝类（牡蛎和贻贝）样本中也检测到了 NP，浓度范围为 ND（未检出）至 7.6×10(3)ng/g dw，平均值为 0.79×10(3)ng/g dw。这些结果表明，NP 在中国东北沿海的沉积物和双壳贝类中普遍存在，甚至在作为海鲜出售的双壳贝类中也有存在。在渤海海峡沿岸以及胶州湾和辽东湾等半封闭沿海环境中，NP 的污染较为严重。本研究了解了可能存在的环境和人类健康影响。
