“…Although the sorptiondesorption of MCPA was also hysteretic with HI values of 0.34-0.77, hysteresis was low and percentages of MCPA desorbed from the soils after four successive desorption cycles were between 48.4-80.6% and not correlated with soil properties (Hiller et al 2012). Consistently higher desorption of MCPA from soils compared to desorption of acetochlor could be attributed to a weaker sorption affinity of MCPA for soil organic and mineral components and its relatively high solubility.…”

“…(1-1/n) .l (1/n) /kg) was approximately 2-8 times lower than that of acetochlor sorption, although soil properties controlling both MCPA and acetochlor sorption were identical (Table 3 and Table 3 in Hiller et al 2012). Thus, differences in the soil sorption between MCPA and acetochlor can be explained by the different physico-chemical properties of the two herbicides.…”

“…Previously, the sorption of 4-chloro-2-methylphenoxyacetic acid (MCPA), which is another commonly used herbicide in the Žitný ostrov area, was determined in the same soil samples as used in the present study (Hiller et al 2012). Comparing the sorption of MCPA with that of acetochlor in the soils, the extent of MCPA sorption (a range of K fs values was 0.37-1.03 mg…”

Tatarková V., Hiller E., Halko R. (2014): Retention characteristics of acetochlor in soils collected from different depths in relation to soil properties (Žitný ostrov area, SW Slovakia). Soil & Water Res., 9: 58-65.Determination of the sorption-desorption of herbicides within soil profile is one of the first steps in predicting their leaching potential. Batch experiments were performed to evaluate the influence of soil properties on acetochlor retention. Soil samples were taken from horizons A, B, and C of three soil types representative of the Žitný ostrov area. The sorption and desorption isotherms were fitted to the Freundlich equation. The Freundlich sorption coefficient (K fs ) values ranged from 0.71 to 6.58 mg(1-1/n) .l (1/n) /kg and were correlated positively with soil organic carbon, humic and fulvic acid carbons, amorphous aluminum oxides, and negatively with soil pH. The Freundlich desorption coefficient (K fd ) values were greater than those for sorption, showing that not all acetochlor sorbed was desorbed after four washing steps. The percentage of acetochlor desorbed ranged from 7.80 to 54.5% with decreased desorption from soil horizons B and C. The higher sorption capacity of surficial soil horizons in the three soils may be a limiting factor for penetration of acetochlor through soil profiles into groundwater.

“…The occurrence of herbicide residues in natural waters may present a risk to water resources with a negative impact on aquatic life. [1][2][3] The pesticides may trigger ecotoxicological problems acting as endocrine disruptor. 4 Therefore, the concern and monitoring of pesticide residues in aqueous environmental matrices is necessary.…”

This paper investigates a strategy as a quality control parameter, using standard surrogate and determination of a relation factor for determination of parathion-methyl, chlorpyriphos and cypermethrin pesticides in environmental aqueous matrices with distinct characteristics (river water, estuarine, seawater and weir water), using the technique of solid phase microextraction gas chromatography with flame ionization detector (SPME-GC-FID). Pesticides were very susceptible to matrix effects promoted by environmental samples. The salinity and the organic matter seem to have been the main sources of interference in the method. For chlorpyriphos, in middle and high levels, the values of relation factor (R f ) for estuarines, seawater and weir matrices were statistically similar. For cypermethrin, the statistical equality occurred in estuarine matrices in medium and high levels of concentration. That indicates proportional behavior between the pesticide and the surrogate recovery, suggesting that a single value of R f can be used as correction factor recovery for any of these matrices.
