In theory, but finds only ambiguous support in empirical research to date economic theory suggests that trade between countries with differing levels of environmental protection could lead pollution-intensive industry to concentrate in inputs (land, labor, capital, and natural resources) and on environmental stringency.
A thick layer of pollution over the indian ocean may be creating atmospheric conditions that promote fierce cyclones intensity of storms between 1979 and 2010 suggests that thick layers of haze have created atmospheric conditions that intensify cyclones and increase the chances they will reach land.

Abstract: the paper describes a series of theoretical aspects concerning residual soil pollution by heavy metals heavy metals, unlike organic and radionuclide pollutants, are considered to be the most persistent/resistant polluting substances in the soil, displaying a tendency for accumulation the behavior of heavy metals. The objective of this chapter is to provide an orientation to the methods that are applied to control and prevent environmental pollution the basic principles followed for eliminating negative impacts on the quality of water, air or land will be introduced the shifting emphasis from control to prevention will be considered and.
