Photoremediation of Carbamate Residues in Water

摘要: Pesticides are extensively world wide used for agriculture and non-agricultural purposes. The major environmental concern of pesticides is their ability to leach down subsoil contaminate the ground water, or, if they immobile, could persist on top soil become harmful microorganisms, plants, animal people (Jha & Mishra 2005; Radivojevic et al., 2008). Harmfull pesticide residues can environment accumulate in ecosystems than entering human food chain (Đurovic 2010; Gasic 2002a; Gevao 2000). have various characteristics that determine how act once where it toxic level. Generally, groundwater pollution consequences effects application. reach water through surface runoff from treated plants soil. Pesticide sprays usually directly hit non-target vegetation or drift volatilize areas air, soil, plants. Finally, using has resulted acute chronic ecological damage either by direct injury such as birds fish indirect. Carbamates large group which been almost sixty years. In this chapter an attempt made give available data carbamates pesticides, physico-chemical toxicological characteristics, behaviour fate environment, types formulations exist market well photochemical degradation certain members. Owing widespread use relatively good solubility carbamate compounds waters therefore carries a risk consumers, environment. we will also discuss some very important photocatalytic methods remediation containing residues: photodegradation (photolysis), photosensitized (including heterogeneous TiO2 ZnO processes photo-Fenton Fenton-like processes).
