“…The K d and Koc values have often been used for predicting the pesticide concentration in aquatic environments. [26] The K d and Koc values of herbicides in this study are calculated and shown in Table 5. The Koc values obtained in this study were higher than those for soils reported by the previous study (Tables 1 and 4).…”

The objective of this study was to clarify the adsorption and desorption characteristics of several herbicides in sediment. Five herbicides, esprocarb, thiobencarb, dimethametryn, pretilachlor, and simetryn were examined in this study. The adsorption ratio on the sediment increased in the following order: pretilachlor < dimethametryn < simetryn < thiobencarb < esprocarb. On the other hand, the adsorption ratio on the sediment without organic matter increased in the following order: thiobencarb < esprocarb < pretilachlor < dimethametryn < simetryn. Furthermore, the amounts of simetryn, dimethametryn, and pretilachlor adsorbed on the sediment without organic matter increased, while those of esprocarb and thiobencarb decreased in comparison to the original sediment. These results strongly suggested that the mineral surface in the sediment was very important as the adsorption site for the herbicide, especially in the case of simetryn, dimethametryn, and pretilachlor. All the adsorption and desorption data fitted well with the Freundlich equation. The hysteresis in the adsorption-desorption phenomena in the sediment was observed for all the herbicides, and it was affected by the organic matter in sediment, especially in the case of dimethametryn and pretilachlor.

“…Interaction and movement between these different compartments (river, estuary, sea, atmosphere, groundwater and land) are studied through mathematical models and on the basis of molecular structure [61,62]. In each compartment, and also at different sites within a single compartment, different chemical reactions can take place due to different conditions (pH, pE, temperature, light, etc.).…”

The analytical determination of organic structures is a fundamental need in environmental, food and medicinal chemistry, and the chemistry of pesticide compounds is closely involved in this determination because of the environmental and biological transformations that can occur to these molecules. Degradation products often possess higher toxicity than parent substances but unknown structures, and aqueous milieu produce hard-to-solve instrumental problems. The need to analyze low concentrations in polar solutions means that methods in which liquid chromatography is hyphenated to mass spectrometry have a large playing field, which combines trace determination and structural elucidation. An important area of study comprises degradation-simulating models, such as titanium dioxide mediated photocatalytic attacks on different organic structures. HPLC-mass spectrometric studies on pesticides, their metabolites and their degradation products are reviewed.
