“…However, at the termination of the experiment, endosulfan residue levels were about 3-10 times higher in fruits than in other tissues. Miglioranza et al (1999) found that high carotenoid levels (lipophilic substances) are responsible for retaining chlorinated hydrocarbons in the body and peel of vegetables, and we believe this to explain the higher endosulfan residue levels in fruits than in leaves at the termination of the experiment.…”

“…According to Trapp et al (1994) and Miglioranza et al (1999), the anatomical and physiological features that enable plants to accumulate nutrients, water, and carbon dioxide also allow them to take up anthropogenic chemicals from air, water and soil via roots (and translocated by the xylem) and, to some extent, across the surface of leaves and other tissues. Several researchers have studied the occurrence of pesticide residues in crops.…”

It has largely been responsible for the "green revolution", i.e. the massive increase in food production obtained from the same surface of land with the help of mineral fertilisers (nitrogen, phosphorus, potassium), more efficient machinery and intensive irrigation. The use of pesticides helped to significantly reduce crop losses and to improve the yield of crops such as corn, maize, vegetables, potatoes and cotton. Notwithstanding the beneficial effects of pesticides, their adverse effects on environmental quality and human health have been well documented worldwide and constitute a major issue that gives rise to concerns at local, regional, national and global scales (Planas et al., 1997; Huber et al., 2000; Kidd et al., 2001; Cerejeira et al., 2003). Residues of pesticides contaminate soils and water, persist in the crops, enter the food chain, and finally are ingested by humans with foodstuffs and water. Furthermore, pesticides can be held responsible for contributing to biodiversity losses and deterioration of natural habitats (Sattler et al., 2006). There have been reported instances of pest resurgence, development of resistance to pesticides, secondary pest outbreaks and destruction of non-target species. Despite the fact that pesticides are also applied in other sectors, agriculture can undoubtedly be seen as the most important source of adverse effects (Hoyer and Kratz, 2001; cited in Sattler et al., 2006).The application of different pesticides varies with the region. For instance, in North Ameri...

“…Forty five out of 47 shallow subsurface soils had b/c ratios ranging from 0.09 to 29.47 with a median of 2.30. As for the deep layer soils, the b/c ratios were in the range of n.d. to 7.78 with a median of 0.52, lower than those of the shallow subsurface soils because of c-HCH being readily leached into the soil (Simonich and Hites, 1995;Miglioranza et al, 1999). The contour maps of the ratios of b/c isomers provide a clear overview of the proportions of two HCH isomers in the studied area (Fig.…”

“…6) showed that highest DDT/DDE ratios for the shallow subsurface soils and deep layer soils were located at the southwest and southeast sites, respectively, where high DDTs levels were found. Extremely high ratios were found in the deep layer soils, probably because of the long-term leaching of p,p 0 -DDT and retarded degradation of DDT to DDE in the deep layer soils (Miglioranza et al, 1999;Harris et al, 2000). Great proportions of p,p 0 -DDT were also observed in agricultural soils of central Germany (Manz et al, 2001) and of southern Ontario (Meijer et al, 2003), and in some western USA soils (Hitch and Day, 1992).…”

“…OCP residues have been studied in different soil horizons (Boul et al, 1994;Miglioranza et al, 1999;Weiss, 2000;Feng et al, 2003), and much attention was paid to the shallow subsurface soils. There are very limited data available for the deep soil layers, which is an indicator of potentiality of OCPs present in the groundwater contamination.…”

The use of pesticides has resulted in increased crop production but also raised concerns about potential adverse effects on the environment. The knowledge of pesticide environmental behavior, like soil adsorption, leaching, and volatility, is necessary to asses the risk to the environment and humans. The properties of pesticides, such as herbicides, insecticides, and fungicides, combined with the amount applied, determine how many pesticides can be transported along each route into the environment. Among insecticides, the monitoring of organochlorine pesticides (OCP) with low water solubility and high environmental persistence is highly recommended. Field studies determined that soil characteristics, topographic position, and land uses influence in OCP accumulation. The accumulation pattern represent a dynamic balance between deposition and erosion in association with wind‐induced circulation, tillage management practices, and effects by natural processes, such as rainfall and flooding periods, according to different soils. Moreover, the use of pesticides on agricultural land may have a negative effect on nearby aquatic ecosystems. This effect is determined by the specific chemicals used, the place and methods of application of the chemicals, and the various mechanisms available for transporting compounds to the waterbodies, with soil erosion being a major pathway. Hydrophobicity and persistence are the main properties of pesticides that control their accumulation in sediment and aquatic biota. Thus, this fact confirms the current necessity of OCP monitoring in natural areas.
