Although plants have the inherent ability to detoxify xenobiotics‚ they generally lack the catabolic pathway for the complete degradation of these compounds compared to microorganisms

APPSC G1 Mains - Paper 4 - Section 2 - Unit 3 The term "Environment" is defined as our surroundings which includes the abiotic component (the non living) and biotic component (the living) around us. The abiotic environment includes water‚ air and soil while the biotic environment consists of all living organisms – plants‚ animals and microorganisms. Environmental pollution broadly refers to the presence of undesirable substances in the environment which are harmful to man and other organisms. In

employed in a variety of contaminated site cleanup programs. It is recognized that no single specific technology may be considered as a panacea for all contaminated site problems. An easy-to-use summary of the analysis of the important parameters that will help in the selection and implementation of one or more appropriate technologies in a defined set of site and contaminant characteristics is also included. q 2004 Elsevier Ltd.

metalloids in high amounts in the soil. Some of the major sources of these pollutants are mining‚ smelting‚ mellaurgical industries‚ sewage sludge treatment‚ fertilizers‚ warfare and military training‚ electronic industries etc. (Padmavathiamma and Li 2007). There are several ways to remediate the soil chemically‚ physically‚ or biologically. However‚ chemical and physical treatments may seem to affect the soil properties heavily‚ affect biodiversity‚ make soil less fertile for plant growth and can

Abstract: Soil serves as one of the basic medium of life as a variety of elements‚ which are vital to life are embedded in it. However‚ the human activities are polluting the soil unintentionally. Consequently‚ a wide range of contaminants enter the soil. Nevertheless‚ heavy metals are the most toxic of all the pollutants. Among these‚ lead‚ cadmium‚ chromium‚ mercury and arsenic are most toxic and can cause multiple organ damages even when present in small amount. Although‚ these elements are necessary

develop transgenic biological agents that digest specific existing compounds in polluted soils and water‚ and to develop new biodegradable compounds to replace hazardous chemicals in industrial activity. Research is‚ therefore‚ aimed at bioremediation‚ which could identify biological agents that rapidly degrade existing pollutants in the environment‚ such as heavy metals and toxic chemicals in soil and water‚ explosive residues‚ or spilled petroleum. Crude oil however‚ is naturally biodegradable‚ and species

the Gulf of Mexico‚ from BP’s Deepwater Horizon‚ has brought the use and effectiveness of bioremediation back into the news. Recruiting bacteria and other microbes to break down synthetic waste is an immensely appealing idea. Putting microorganisms to work in this manner is the crux of bioremediation (Alcamo‚ Weeks‚ 2008). The work to clean up the Horizon spill actually started in the 1800’s when night-soil men would go from house to house and collects sewage; the sewage would then be taken to fields
