Determination of organochlorine pesticides in agricultural soil with special reference to γ-HCH degradation by Pseudomonas strains

Identification and Growth Characterization of a Novel 2,4-D (Dichlorophenoxyacetic Acid) Degrading Bacterium Maribacter Sp Amsu Isolated From Aquaculture Effluent

“…In India, alarming levels of pesticides have been reported in air, water, soil as well as in foods and biological materials (Viswanathan, 1985;Agarwal et al, 1986;Nawab et al, 2003). The most important pollutants among the toxicants in India are organo chlorine and organo phosphorus pesticides.…”

Analytical Methods for Viable and Rapid Determination of Organochlorine Pesticides in Water and Soil Samples

“…Extraction is a critical sample preparation step for the analysis of OCPs in soil samples because these hydrophobic compounds are strongly sorbed to the soil material. Various extraction procedures including soxhlet (Wobst et al, 1999;Fatoki & Awofolu, 2003;Bakan & Ariman, 2004), shaking flask (Kolb et al, 1995;Pozo et al, 2001;Nawab et al, 2003), sonication (Babic et al, 1998;Gonçalves & Alpendurada, 2005;Banjoo & Nelson, 2005;Castro et al, 2001), microwave assisted extraction (MAE) (Camel, 2000;Ericsson & Colmsjo, 2000;Pino et al, 2000;Jayaraman et al, 2001), super critical fluid extraction (SFE) (Reindl & Hofler, 1994;Barnabas et al, 1995;Koinnecke et al, 1997;Benner, 1998;Morselli et al, 1999) and pressured liquid extraction (Lundstedt et al, 2000;Ramos et al, 2000;Richter, 2000) can be used for the extraction of target compounds from soil. Moreover, determination of OCPs in soil can be carried out by using German standard method (DFG S-19 multimethod) (DFG, 1987) andISO 10382 (ISO, 2002).…”

Analytical Methods for Performing Pesticide Degradation Studies in Environmental Samples

“…That amount increased to $2.5 million in 2007 (Andreu & Picó, 2004). The use of pesticides in the world has increased five fold in the last 30 years (Nawab et al, 2003).…”

“…In addition to the toxicity to humans, the presence of these products in the environment poses a risk to water quality and the ecosystem (Veiga et al, 2006). When applied to the soil, they can reach other levels as a result of mobility, sorption, volatilization, erosion, and leaching, thereby contaminating various environments (Andreu & Picó, 2004;Nawab et al, 2003), as is shown in Fig. (1).…”

“…(Strandberg et al, 1998;Bavcon et al, 2002, adapted) Other important aspects to be considered are the products of pesticide transformation (TP). There is great interest in studies on the formation of pesticide sub-products in the environment, since they can present a greater risk to the ecosystem than the original pesticides (Nawab et al, 2003;Sinclair & Boxall, 2003;Pozo et al, 2001;Sabik et al, 2000). On the other hand, some pesticide TP may present lower toxicity than the original substances from which they are formed (Borga et al, 1998).…”
