Climate changes enhances the effect of dangerous substances

The conclusion from a rapport made by experts on climate and chemistry from 12 states is that the climate changes increases the earth’s vulnerability for the dangerous substances and reinforces the negative health and environmental effects from these substances.

Under the Stockholm Convention there has been prepared a scientific report that compiles knowledge about how changes in climate could affect transportation and the availability of persistent organic pollutants (POP's), from a global perspective. The rapport has been prepared by the Arctic Monitoring and Assessment Programme (AMAP) as a common project with the Secretariat of the Stockholm Convention. The rapport is the first systematical compilation about what we know about the linkages between the climate effects and the availability of POPs in the industry.

The consequences of the climate change on dangerous substances are after the rapport several. A increase of temperature will again increase the spread of POPs in the environment, and increase the spread of them over bigger distances. The increase of extreme weather releases dangerous substances trough erosion and leaching. Higher temperature will affect the uptake of POPs in plants and animals.

Experts point out that the increase in temperatures and subsequent changes in the effects of POPs, will have serious consequences for animal and plants. This was confirmed in the flood in Pakistan, where increased levels of dangerous substances in the drinking water and in the water in the rice production fields, proved to be disastrous.

The rapport identifies gaps, and makes recommendation on strategy of further work on the area. The importance of good coordination and communication between the different actors in climate and environmental pollutant issues is also a topic in the rapport.
