“…Hazard identification is an evaluation of the potential effects and concerns related to the intrinsic properties of a substance [9][10][11][12]. Thus the goal of hazard identification is to identify all situations or substances that can, under any (reasonable) circumstances, pose a risk to human health or the environment [13].…”

“…It is generally believed that the fate of organic pollutants in river water depends mostly on the sorption processes occurring on organic matter of different granulometric sizes, going from sediments to particles and colloids [6,7,8,9,10,11,12,13,14,15,16,17,18]. In these conditions, the elimination and transfer of herbicides should be controlled by the size of the particles on which they are adsorbed.…”

“…In contrast, for fine particles, like colloids, the transfer of herbicides takes place horizontally. It is worthwhile to stress that moderately hydrophobic pollutants such as herbicides can be weakly adsorbed on organic particles [9,10,11,12,13,14,15,16,17]. As a matter of fact, the adsorption process on colloids may play a key role in the herbicide mobilities as well as in their chemical and/or microbiological degradation [18,19].…”

“…It is based on the study of sorption on colloids from soils and ground waters [9,10,11,12,13,14,15,16,17]. From this standpoint, organic micropollutants are probably retained by colloids and then transferred from soil to river and/or from ground water to river (Fig.…”

“…dissolved organic matter passing through a 2 nm polysulfone membrane). However, most authors have studied the interactions of organic pollutants between particles and dissolved phase which is defined as the organic matter passing through a 0.7 µm GF/F glass fibre filter [6,7,8,9,10,11,12,13,14,15,16,17,18,19]. In these studies, different partitioning coefficients have been used to describe the sorption phenomena.…”

For moderately hydrophobic compounds such as most pesticides adsorption on colloids (<0.2 microm) may play a key role in pesticide mobility as well as in their degradation by chemical and microbiological processes. However, until now, pesticide-organic colloid interactions are poorly understood. Quantitative data for sorption equilibria on colloids of two series of herbicides including triazines (atrazine, simazine, terbutylazine, prometryne, desethylatrazine, and desisopropylatrazine) and phenylureas (isoproturon, linuron, neburon, and diuron) sampled in the Seine river (urban zone) and the Marne river (agricultural zone) are presented. Partition coefficient of herbicides on colloids (K(com)), were evaluated by solid-phase extraction coupled with high-performance liquid chromatography-UV diode-array detection (SPE-HPLC-UV/DAD). In the case of triazines a satisfactory log-log correlation was found between K(com) and octanol-water coefficient (K(ow)) values. Phenylureas did not obey this correlation, with K(com) values being about two times higher than those of triazines. The existence of two distinct types of adsorption behaviour on colloids partly explains the different occurrence of triazines and phenylureas in surface waters.

Water plays an important role in our daily life. Natural water in each compartment on Earth is balanced through a hydrological cycle. With the population increase, industrialization, and rapid urbanization, water quality has been affected and an increased demand for water use has occurred. Anthropogenic substances are discharged into our aquatic environment. As a consequence, water contamination has been found in many rivers, streams, and lakes globally. Facing our current water environmental problems, water resources management and aquatic environmental protection and restoration are important issues to us. In the United States, water quality has been improved significantly since 1972 when the Clean Water Act was enacted by the U.S. Environmental Protection Agency. In this article, we introduce the classification of waters based on the reservoir they reside in and discuss the water quality, water pollution, and aquatic environmental legislations. This article gives a general overview of water classification, quality assessment, and legislations. Greater efforts are still needed to protect the aquatic environment and improve water quality.
