Nonylphenol (NP) has provoked much environmental concern because of their weak estrogenic activities; however, few data are available on the environmental levels of the chemical in China.
Environmental or river samples were assayed for NP by high-performance liquid chromatography (HPLC) technique.
The concentration for NP measured in Xiangjiang River, ranging from 0.174 to 3.411 μg/L with a mean value of 1.73 μg/L, was lower than the Water Quality Criteria for NP of the US (6.6 μg/L); however, the NP concentration was maintained at a higher level compare to the developed countries and other civil cities. NP concentration in downstream water was markedly higher than that both in midstream and upstream water. Tissue accumulation of NP was observed in aquatics. A ratio of mean concentration of NP in aquatic (chlamys farreri and hemiculter leucisculus) to that in river water was 241 and 1087, respectively. The presence of NP in tap water in two urban districts of Zunyi was common with a detectable rate reached 100.0%. Mean NP concentration in terminal tap water in Huichuan district was six times as high as Honghuagang district, which was above Standards for the Drinking Water Quality for Phenols of China (2 μg/L).
The pollution of NP in Xiangjiang River, tap water, and aquatic in Zunyi belongs to moderate or severe level in the world.
壬基酚（NP）因其微弱的雌激素活性而引发了诸多环境问题；然而，关于中国该化学物质的环境水平的数据却很少。
采用高效液相色谱（HPLC）技术对环境或河流样本中的NP进行检测。
湘江中测得的NP浓度范围为0.174至3.411μg/L，平均值为1.73μg/L，低于美国NP的水质标准（6.6μg/L）；然而，与发达国家和其他城市相比，NP浓度维持在较高水平。下游水体中的NP浓度明显高于中游和上游水体。在水生生物中观察到了NP的组织积累。水生生物（栉孔扇贝和麦穗鱼）中NP的平均浓度与河水中NP平均浓度的比值分别为241和1087。遵义市两个城区的自来水中普遍存在NP，检出率达100.0%。汇川区终端自来水中NP的平均浓度是红花岗区的六倍，高于中国《生活饮用水卫生标准》中酚类物质的标准（2μg/L）。
遵义市湘江、自来水和水生生物中NP的污染在世界范围内属于中度或重度水平。
