In the US it is banned since 1972. It is highly toxic to different marine life, such as crayfish, daphnids and sea shrimp. (b) It undertakes scientific research on environmental issues at global level The use of DDT remains a controversial focus of technocentric and ecocentric views in some parts of the world even though some countries still use it for its effectiveness in combating malaria (Buckley, 1986). "It's got an interesting history. DDT is a persistent organic pollutant that is readily adsorbed to soils and sediments, which can act both as sinks and as long-term sources of exposure affecting organisms. Human health effects from DDT at low environmental doses are unknown. DDT is a highly polluting hazard, which s persistent in the environment and insoluble in the water. It is readily adsorbed to the sediments and the soils. As of 2008, DDT use is confined almost exclusively to the control of mosquito populations in malaria eradication programs in Africa. DDT is a persistent organic pollutant that is readily adsorbed to soils and sediments, which can act both as sinks and as long-term sources of exposure affecting organisms. Breakdown in soil and groundwater: DDT is very highly persistent in the environment, with a reported half-life of between 2-15 years and is immobile in most soils.Routes of loss and degradation include: runoff, volatilisation, photolysis and biodegradation (aerobic and anaerobic). (d) Both (a) and (b). Johnson says DDT was used in Australia as an insecticide. One of the new EPA's first acts was to ban DDT, due to both concerns about harm to the environment and the potential for harm to human health. However, the evidence seems to be highly variable. In January 1970, the first country – Sweden had banned the use of DDT. DDT was banned 40 years ago as a result of Rachel Carson’s, Silent Spring, based on some evidence available at the time. Low or moderate exposure to the DDT may cause diarrhea, nausea, irritation in the eyes, and the higher doses can cause the convulsions and tremors. To access the same, a google account is a must. ENVIRONMENTAL EFFECTS OF DDT 363 Studies carried out at the Patuxent Wildlife Research Center demon- strated that stored residues of DDT could be mobilized during weight loss, and this resulted in mortality after exposure to DDT had stopped (Van Velzen et al., 1972~. But its limited and still-controversial use in disease vector control continues, because of its effectiveness in reducing malarial infections, balanced by environmental and other health concerns. Johnson says DDT was used in Australia as an insecticide. DDT played a part in the eradication of malaria on some continents and a huge drop in the number of cases in others. Bioaccumulation occurs with very littl… DDT may bioaccumulate significantly in fish and other aquatic species, and it also shows biomagnification. Twenty years on, Glen Johnson from the Department of Sustainability and Environment says its effects are still being felt on the environment. According to the EPA , DDT can cause liver damage including liver cancer, nervous system damage, congenital disabilities, and other reproductive harm. DDT, DDE, and DDD was once widely used to control insects on agricultural crops and insects that carry diseases like malaria and typhus, but is now used in only a few countries to control malaria. DDT has some known effects on humans, although at fairly high doses. LTD is the parent company of CIVILSDAILY IAS. Moreover, although DDT was not popular used in recent time, it still impacts on environment and human health due to long residual efficacy and accumulation through food chain. DDT is a persistent, widespread environmental contaminant that causes significant anatomical, behavioral abnormalities and physiological in humans and also wildlife (Iwaniuk, et al., 2006).
