“…On the other hand, a considerable variation in K oc values of pesticides within soils and sediments has been reported. The variation in K oc values of an organic compound has been ascribed to the differences in soil/sediment organic matter polarity, to its aromatic carbon content and degree of polymerisation (Ahmad et al 2001;Dousset et al 1994;Grathwohl 1990;Kile et al 1995Kile et al , 1999Perminova et al 1999) and to the contributions from mineral sorption (Garbarini and Lion 1989;Grundl and Small 1993;Karickhoff 1984). Although the K oc values of acetochlor vary much less than the K d values (see Table 3), there was still a considerable variation in K oc values among the soils and sediments.…”

This study examined the sorption-desorption processes of acetochlor in soils and sediments. The obtained sorption data are important for qualitative assessment of acetochlor mobility in natural solids, but further studies must be carried out to understand its environmental fate and transport more thoroughly. Although, the total organic carbon content, the humus fractions of the organic matter and the C(HA)/C(FA) ratio were sufficient predictors of the acetochlor sorption-desorption. Further investigations of the structural and chemical characteristics of humic substances derived from different origins are necessary to more preciously explain differences in acetochlor sorption in the soils and sediments observed in this study.

“…They obtained values of K d ranging from 0.01 dm 3 kg -1 to 64 dm 3 kg -1 of atrazine with a mean value of 2.4 dm 3 kg -1 . Similar results were reported by Barriuso et al (1992) and Dousset et al (1994). The sorption characteristics of atrazine can be normalized to obtain a general soil sorption constant (K oc ) based on the soil organic carbon (SOC) content.…”

“…It is believed that the greater amount of hydrophilic parts of the fulvic acids might favour the amount of polar MCPA retained by soils and sediments (Haberhauer et al 2002). A similar effect of the organic matter composition on the sorption of organic chemicals by soils and different fractions of fulvic acids, humic acids and humins was shown by Chiou et al (1986) and Dousset et al (1994).…”

“…For example, sorption of MCPA was lesser in the A4 soil (Pararendzina) with higher C HA :C FA ratio than in the L1 river sediment with low C HA :C FA ratio (t-test, P < 0.05), even though the organic carbon content was almost the same (Tables 1 and 2). Lower C HA :C FA ratio is considered to be an indicator of higher organic matter polarity or smaller degree of polymerisation (Dousset et al 1994) in the L1 sample, which can therefore contain more active sorption sites suitable for binding of polar herbicides such as MCPA (Haberhauer et al 2001) in comparison to majority of soil samples having C HA :C FA ratio higher than 1.…”

MCPA sorption and desorption in five surface soils (denoted as A1-5), three bottom sediments (S1-3), two river sediments (L1-2) and one subsurface soil (SS) at two initial concentrations in aqueous solution -C 0 = 0.5 and 10 mg/l were studied. No significant effect of the initial concentration on MCPA equilibrium distribution between soil/sediment and aqueous solution was observed. The difference between distribution coefficient K D at C 0 = 0.5 mg/l and K D at C 0 = 10 mg/l was found only in the case of one bottom sediment (S2). A simple regression analysis between K D at C 0 = 0.5 and 10 mg/l and soil/sediment properties indicated that the most important property which determined the variation in MCPA sorption is organic carbon (r = 0.886*** and r = 0.926***, respectively). Similarly, desorption of MCPA was inversely proportional to organic carbon content of the soils and sediments used (r = -0.862* and r = -0.842**). These observations showed that MCPA sorption and desorption in soils and sediments were primarily controlled by organic components of the geosorbents used. Overall, the percentage of MCPA sorption in soils and sediments was low (P sorp ≈ 3-53%; K D = 0.077-2.827 l/kg) and the percentage of MCPA desorbed was relatively high (P des ≈ 11-70%), especially in the soils and sediments with lower organic carbon content. The experimental results and calculated values of groundwater ubiquity score GUS and relative leaching potential index RLPI imply that MCPA is very mobile in all the surface soils and has a potential to contaminate groundwater.
