  • Modeling global emissions and residues of pesticides

    A major portion of persistent organic pollutants (POPs) is organochlorine pesticides (OCPs), in which carbon and chlorine are combined. During the last decade, a number of researches have been devoted to create emission inventories of OCPs at regional and global scales. The studies on residue inventories of OCPs, however, are sparse. In the absence of complete data and information on worldwide ...

  • Levels of organochlorine pesticides residues in meat

    Abstract: Concentrations of organochlorine pesticides (Lindane, Aldrin, Dieldrin, Endosulfan, DDT and DDE) residues in beef samples from the Kumasi and Buoho abattoirs in Ghana were determined using gas chromatography. Organochlorine residues were found in all the samples. The average concentration of lindane in beef fat samples from Kumasi was 4.03 µg/kg and 1.79 µg/kg in beef fat from Buoho. ...

  • Quality control of immunoassays for pesticide residues

    I. Abstract Quality control of any analytical method is integral to its ability to produce reliable results. To adequately control a method, one must first understand the sources of variability. Some sources of error in an immunochemical method are similar to those of a traditional chromatographic technique. Immunoassays also present some unique potential error sources along with novel ...


  • Complete Solutions for Pesticide Residue Analysis in Foods

    Pesticides are widely used in many areas of modern agriculture as they are considered economically important for high yield production. In today’s world of extensive importing and exporting of food goods, the analysis and monitoring of pesticides is essential, although challenging.The determination of an effective, standardized approach for extracting pesticides from food sources and ...


  • Transfer and translocation of organochlorine pesticide residues in an agricultural area of Romania

    The study refers to translocation of some organochlorine persistent pesticides (Lindane, Aldrin, Endosulphane and DDT) in/from soil to surface and underground water and their accumulation in some crops in an agricultural area nearby Bucharest. The samples analysed were soil, surface water (Arges River) and underground water (wells). Pesticide residues were found especially in soil samples, in ...

  • Analysis of Multi-Pesticide Residues in Vegetables, Food, and Fruits by SPE/GC-MS

    Cleanup of matrices is the first, the most important, and the most critical step for both broad-spectrum screening and accurate determination of pesticides and their metabolites in vegetables,meats, drinks and fruits. In most cases, solid phase extraction (SPE) methods are used to clean up the extracts before the GC-MS analysis. The ideal SPE material(s) should remove the greatest number of food ...

  • Organochlorine pesticide and PCB residues in pharmaceutical, industrial and food grade fish oils

    Oils rendered from whole fish and from fish offal are an important primary dietary item in many areas of the world. In addition, fish oils are used extensively in the food industry as raw materials and ingredients. An extensive specialist market also exists for fish oils in dietary supplements. Traditionally, benefits have been conferred by their high vitamin D content in the prevention and cure ...

  • Dry–wet cycles increase pesticide residue release from soil

    Soil drying and rewetting may alter the release and availability of aged pesticide residues in soils. A laboratory experiment was conducted to evaluate the influence of soil drying and wetting on the release of pesticide residues. Soil containing environmentally long‐termaged (9–17 years) 14C‐labeled residues of the herbicides ethidimuron (ETD) and methabenzthiazuron (MBT) and the fungicide ...

  • Pesticide Terminator

    Impacted Soil Bioremediation - Environmental Protection magazine (May 2007) As urban centers grow in size, substantial areas of agricultural and industrial land are being converted to residential use. One of the issues frequently encountered when such a change in land use is implemented is the presence of elevated concentrations of chlorinated pesticides and herbicides historically used in ...


  • Analysis of Non-Volatile Pesticide Residue in Vegetables by Positive/Negative ESI LC/MS/MS

    IntroductionPesticide residue analysis in vegetables has increased dramatically in recent years due to the quality improvement in theagricultural production (1,2) and governmental monitoring of food safety (3).In Almería, the largest agricultural region in Spain, it is very important to determine the maximum number of residues inthe highest number of samples per day. Fast, highly selective and ...


  • Comparing pesticide residues in Amish and commercially grown strawberries and spinach using QuEChERS, Various dSPE Sorbents, and GC-TOFMS

    Abstract QuEChERS extraction, dSPE cleanup, and GC-TOFMS analysis were used to assess pesticide levels in strawberries and spinach from both commercial and Amish growers. Various dSPE cleanup products were compared to determine which were most effective. Good recoveries were obtained for most pesticides; however, low recoveries were observed for some base-sensitive or planar compounds. ...

  • The interaction between natural organic matter in raw waters and pesticide residues: a three dimensional excitation–emission matrix (3DEEM) fluorescence investigation

    This paper examines the interaction between dissolved natural organic matter and pesticide residues, both of which are found in raw water sources, using three dimensional excitation–emission matrix (3DEEM) fluorescence spectroscopy. It was observed that pesticide residue at 0.1 mg L−1 formed a complex with humic-like fluorophores that are commonly found in raw water samples. ...

  • Analysis of pesticide residues in drinking water samples using solid-phase micro-extraction (SPME) coupled to a gas chromatography-electron-capture detector (GC-ECD)

    The headspace solid-phase micro-extraction (HS-SPME) method with polydimethylsiloxane (PDMS, 100 μm) fiber is a cost-effective technique for the determination of different pesticide residues in environmental and biological samples followed by a gas chromatography-electron-capture detector (GC-ECD). In the present study more than 147 water samples collected in and around Lucknow city were ...
