Vertical Distribution of Nonylphenol Ethoxylates and Their Derivatives in Sediments of a Freshwater Reservoir

Abstract: The distribution of nonylphenol ethoxylates (NPEOn) and their derivatives of nonylphenol (NP) and nonylphenoxy ethoxy acetic acids (NPEnC) in the sediments of a relatively closed freshwater reservoir was investigated using sediment layers sliced from undisturbed sediment cores collected with a gravity core sampler at three sampling sites (St. 1, St. 2 and St. 3) along the water flow direction. The relationships between the bound content of these compounds and the sediment organic matter as well as the likely t… Show more

“…The use of sediment from the pre-reservoir, rather than the main reservoir, was mainly due to the considerations that this pre-reservoir is a natural reservoir and it has been frequently used as the study site for investigation of the occurrence and behavior of a variety of pollutants (including nitrogen, phosphorus, nonionic surfactants and natural estrogens) with the projects from the Ministry of Land, Infrastructure, Transport and Tourism of Japan 13,14) ; and the large number of data obtained so far can facilitate future comparisons of the behavior of different pollutants including cesium targeted in this study.…”
