Determination of pesticides in soil using GC-MS analytical technique.

Order Description Write a bibliographic review and case study The case study should include: explanation about the pesticide, its exciting in the soil, its effects on the soil, and what is the limit of the pesticide in the soil regarding to the global recommendation and regulation. In addition, what it is GC-M, why it is efficient analytical method for determination of pesticide in soil samples ?, what are the advantages and disadvantages. Moreover, this term paper should include analyzing and explanation of previous studies that are related to the topic. Statements should be supported by evidence and citations. Examples of Case studies  Gas Chromatography analytical instrument for environmental analysis and monitoring.  ICP as analytical instrument for determination of trace metals in water.  GC-MS as analytical instrument for determination of organic chemicals in water.  GC-MS as analytical instrument for determination of organic chemicals in oil-contaminated soil.  Determination of volatile organic compounds (VOCs) in air by GC-MS.  ICP-OES assessment of heavy metal contamination in marine sediments: overview and the digestion techniques  Toxic metals distribution in cigarettes by electrothermal atomic absorption spectrometer.  Size-exclusion chromatographic columns for the clean-up of pesticides in soils.  On-line UV/vis spectroscopy in monitoring and controlling waste-water treatment plants  Gas Chromatographic Analysis of Drugs of Forensic Interest.  Application of Ion chromatography in water quality [chlorate and chlorite].  High performance liquid chromatography [HPLC] method for monitoring pharmaceuticals residues in environmental samples.  Determination of volatile organic compounds(VOCs) level in different compartments using different instruments.  Application of adsorption method to the chromatographic analysis of free drug concentration.  Application of Fourier transform infrared (FTIR) Spectroscopy to Agricultural Soils Analysis.
