位于Pawtuxet河（美国罗得岛）的一家小型特种化学品制造厂的废水污染了该河、Pawtuxet湾、普罗维登斯河和（在较小程度上）纳拉甘塞特湾的水和沉积物。由于该系统中发现的化合物涵盖了广泛的功能，极性和水溶性，该系统的详细研究，使我们能够评估几种化合物类型的环境行为在1水生系统。各种化合物的水溶液浓度遵循简单稀释的规则，并且具有最高辛醇-水分配系数（log P）的那些化合物与水中的颗粒物质密切相关，并且在距离植物最远的沉积物中发现。给定化合物的沉积物浓度（C）可以通过log（C 0/C）= b 0 + b2（dist/log P）从其log P值和其在废水中的浓度（C 0）预测，其中dist是沉积物样品与工厂的距离，b 0和b2是拟合数据的常数。
The wastewater from a small speciality chemicals manufacturing plant located on the Pawtuxet River (Rhode Island, USA) has contaminated the water and sediment of that river, the Pawtuxet Cove, the Providence River and (to a lesser extent) the Narragansett Bay. Since the compounds found in this system cover a wide range of functionalities, polarities and water solubilites, a detailed study of this system has allowed us to assess the environmental behavior of several compound types in 1 aquatic system. The aqueous concentrations of the various compounds follow the rules of simple dilution and those compounds with the highest octanol-water partition coefficients (log P) are strongly associated with the particulate matter in the water and are found in the sediment at the greatest distance from the plant. The sediment concentrations (C) of a given compound can be predicted from its log P value and from its concentration in the wastewater (C0) by log (C0/C) = b0 + b2(dist/log P) where dist is the distance of the sediment sample from the plant and b0 and b2 are constants fitted to the data.
