“…The use of aldrin, dieldrin, and endrin has been severely restricted or banned in several countries, especially in agriculture, since the 1970s [1]. Although the use of these pesticides has been restricted or banned for more than three decades, dieldrin is still detected in some crops, especially in cucurbits [2,3]. Also, in Japan, dieldrin has been detected in the fruits of cucumbers [4].…”

It has been known that the Cucurbitaceae family takes up a large amount of persistent organic pollutants from soils and that the translocation of those compounds in cucurbits is higher than those in non-cucurbits. To understand the persistent organic pollutant uptake mechanisms of plant species, we compared the dieldrin absorption and transportation potentials of several plants in hydroponic medium. Sorghum (Sorghum vulgare Moench), sunflower (Helianthus annuus L.), soybean (Glycine max), komatsuna (Brassica rapa var. peruviridis), white-flowered gourd (Lagenaria siceraria var. hispida), cucumber (Cucumis sativus L.), and zucchini (Cucurbita pepo L.) were grown in a dieldrin-added hydroponic medium for 10 d, and then the amount of dieldrin in their shoots and roots was measured. All of the roots contained dieldrin, whereas only the cucurbits (white-flowered gourd, cucumber, and zucchini) contained considerable amounts of dieldrin in their shoots. The dieldrin uptake to the roots depended on the concentration of the n-hexane soluble components in the roots, regardless of whether the dieldrin in the roots was translocated to shoots or not. The dieldrin uptake from the solution to the roots was thought to be due to a passive response, such as adsorption on the roots. The translocation of dieldrin from the roots to the shoots was probably through the xylems. The amounts of dieldrin in the shoots per transpiration rates were higher for cucurbits than for non-cucurbits. It seems likely that cucurbits have uptake mechanisms for hydrophobic organic chemicals.

“…The fact that HCH and DDT are still present in measurable concentrations in many of the sampled soils means that these residues resisted degradation, leaching, and volatilization due to strong sorption (Hilber et al 2008). The intensity of HCH and DDT degradation depends upon several environmental factors and soil parameters such as total organic carbon (TOC), soil texture, soil pH, water content and temperature, as well as the structure of the pesticides (Manz et al 2001;Wenzel et al 2002;Miglioranza et al 2003a;Hilber et al 2008).…”

In this study, soil samples were categorized into four types of textures (loam, light loam, sandy loam, and sandy soil) to delineate the influence of soil texture on HCH and DDT residue levels.…”

The factors that influence the dynamics of hexachlorocyclohexane (HCH) and dichlorodiphenyltrichloroethane (DDT) in soils around the watersheds of Beijing reservoirs were examined. Compared with other studies on HCH and DDT in soils and established reference values, the concentrations of HCH and DDT in soils around our study area were relatively low. The relationships between HCH and DDT concentrations and land use, soil texture, and soil properties were discussed. HCH and DDT concentrations were higher in arable soils than those in uncultivated fallow soils. Although land use was the most important factor affecting HCH and DDT residues, additional factors such as soil texture and soil total organic carbon were also involved in pesticide retention in soils. The results indicated that the historical agricultural applications of HCH and DDT were the major source of their residues. Atmospheric deposition, as well as long-distance transportation and inputs from surrounding weathered agricultural soils may also serve as important sources of HCH and DDT residues in the watersheds.
