DDT is currently used in indoor residual spraying (IRS) for malaria vector control in several countries, in accordance with the recommendations and guidelines of the World Health Organization (WHO). Nonetheless, this chemical is among the 12 persistent organic pollutants (POPs) the production or use of which is restricted by the …
Indoor Residual Spraying (IRS), insecticide-treated nets (ITNs) and long-lasting insecticidal nets (LLINs) are key components in malaria prevention and control strategy. However, the development of resistance by mosquitoes to insecticides recommended for IRS and/or ITNs/LLINs would affect insecticide-based malaria vector control. We assessed the susceptibility levels of Anopheles arabiensis to …
Company argued it was following globally accepted norms. The Supreme Court today quashed the prosecution of soft drink giant PepsiCo by the Kerala government over the pesticide content found in its bottles picked at random from the market. A three-judge bench headed by Justice Altamash Kabir set aside the criminal …
As part of the Global Atmospheric Passive Sampling (GAPS) study, XAD-resin based passive samplers are being deployed for consecutive one-year periods at numerous sites on all seven continents to determine annually averaged concentrations of persistent organic pollutants. Concentrations of banned organochlorine pesticides as well as a number of current-use pesticides …
Persistent organic pollutants (POPs) are toxic chemicals that resist degradation and bioaccumulate. Despite attempts to limit the use and distribution of these chemicals, they are still widely detected in the environment. Schecter et al. determined the presence of POP contamination of food in the United States by measuring perfluorinated compounds …
How do climate fluctuations affect DDT and hexachlorocyclohexane (HCH) distribution in the global scale? In this study, the interactions between climate variations and depositions of DDT and HCH in ice cores from Mt. Everest (the Tibetan Plateau), Mt. Muztagata (the eastern Pamirs) and the Rocky Mountains were investigated. All data …
This study sets out the importance of analysing a specific situation in order to develop a holistic strategy of interventions which will be appropriate to the vectors and the local conditions. The strategies proposed recognise the importance of community participation, health education, surveillance, improving public health systems, decentralization of malaria …
The objective of this study is to review the status of dichlorodiphenyltrichloroethane (DDT), used for disease vector control, along with current evidence on its benefits and risks in relation to the available alternatives.
In many parts of the world, deliberate indoor residual spraying (IRS) of dwellings with insecticides to control malaria transmission remains the only viable option, thereby unintentionally but inevitably also causing exposure to inhabitants. Because mothers are exposed to insecticides via various routes, accumulated residues are transferred to infants via breast …
Dichlorodiphenyltrichloroethane (DDT) was used worldwide until the 1970s, when concerns about its toxic effects, its environmental persistence, and its concentration in the food supply led to use restrictions and prohibitions. In 2001, more than 100 countries signed the Stockholm Convention on Persistent Organic Pollutants (POPs) , committing to eliminate the …
The Centre on Friday informed Parliament that the use of the DDT other than in eradication of diseases like malaria and kala azar, is completely banned in the country. Replying to supplementaries raised by BJP member Rajiv Pratap Rudy in the Rajya Sabha, minister of state for chemicals and fertilisers, …
Many chemicals are dangerous to human and ecosystem health. Among the worst is a range of synthetic organic compounds that persist in the environment for long periods of time. GEF
The Obama administration said on Friday it will keep a Bush-era rule that weakens protection for polar bears' icy habitat and plays down links between the threatened status of the species and climate change. "Seeing the polar bear's habitat melting and an iconic species threatened is an environmental tragedy of …
Nine dangerous chemicals used in farming and industry will be added to a list of banned substances whose presence in the environment causes serious health risks, more than 160 government agreed on Saturday. The nine pesticides and industrial chemicals join 12 substances targeted for elimination under the 2001 Stockholm Convention …
In the present study, the possibility of biodegrading the dechlorinated product of 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane (DDT), 1,1-dichloro-2,2-bis(chlorophenyl) ethylene (DDE) and structurally related compound 1,1-dichloro-2,2-bis(chlorophenyl)-ethane (DDD) under aerobic conditions was examined.
A thaw of the Arctic linked to global warming may slow a drive to get rid of industrial chemicals that are harming indigenous people and wildlife, an expert said on Monday. About 150 nations are meeting in Geneva this week to consider adding nine chemicals, including pesticides and flame retardants, …
Ocean currents work magic when they help ships navigate from one place to the other or bring rain. However, together with the Horse latitudes, they also have created a new continent as big as Africa and still expanding, which may never support life because it is plain garbage, dubbed the …
State Minister for Environment and Forest Mustafizur Rahman said the government is going to develop a strategy soon for sustainable waste management to keep the environment toxic-free.
California sea lions have a large body burden of organochlorine pesticides, and over the last decade they have also been subject to domoic acid poisoning. Domoic acid poisoning, previously recognized in adult animals, is now viewed as a major cause of prenatal mortality. The appearance of a chronic juvenile domoic …
