Highly toxic compounds released to the environment due to the various effects of global warming, threatening the existence of mankind. Participants said this climate summit in Cancun, Mexico.
Because of climate change increases the vulnerability of the planet to the so-called persistent organic pollutants (POPs). These hazardous substances are more likely to end in the ecosystem and, ultimately, threaten the health of mankind. This is stated in a report of the UN Environment Programme, reports RIA "Novosti".
"We continue to discover more and more the consequences of climate change, which have not been seen before," — said the director of the National Institute of Ecology of Mexico Adrian Fernandez. Substances which enter into the ecosystem experts fear could lead to severe metabolic disorders, immune, respiratory and circulatory systems, as well as various forms of cancer.
Extreme weather events, power and frequency of which, according to expert predictions, due to climate change will only increase, lead to violations of the conditions of storage of hazardous substances. So, some POP before disposing collected in special containers and storage, which even at the right mode of operation may be affected by the floods and hurricanes. Experts cite the example of Pakistan. In this country in the summer of 2010 there was a series of severe floods. A temporary Pakistani tanks stored over 6 thousand tons of toxic substances.
Another negative factor in global warming, environmentalists believe the so-called biological accumulation of POPs, the concentration of which increases as you move up the food chain. The increase in temperature will do its links more vulnerable to contaminants that may ultimately affect the health of people, experts believe.
POP group also called "dirty dozen." The list, which includes DDT, various insecticides, pesticides and fungicides, was formed in 2001 by the Stockholm Convention on Persistent Organic Pollutants. In 2009, the list of proposed increase to 21 points. The main sources of toxic compounds are considered hazardous waste incineration plants, cement kilns, pulp production, some companies metalworking, plastics industry, as well as almost the entire transport sector.
