air pollution (sh) and New Siberian Islands (sh)


air pollution (sh)




Release into the atmosphere of gases, finely divided solids, or finely dispersed liquid aerosols at rates that exceed the capacity of the atmosphere to dissipate them or to dispose of them through incorporation into the biosphere.

Dust storms in desert areas and smoke from forest and grass fires contribute to particulate and chemical air pollution. Volcanic activity is the major natural source of air pollution, pouring huge amounts of ash and toxic fumes into the atmosphere. Air pollution may affect humans directly, causing irritation of the eyes or coughing. More indirectly, its effects can be measured far from the source, as, for example, the fallout of tetraethyl lead from automobile exhausts, which has been observed in the oceans and on the Greenland ice sheet. Still less direct are possible effects on global climates. See also smog.


New Siberian Islands (sh)




Island group, Arctic Ocean, northeastern Russia, north of eastern Siberia.

The islands divide the Laptev Sea from the East Siberian Sea. They are separated from the Siberian mainland by Dmitry Laptev Strait. With an area of about 14,500 sq mi (38,000 sq km), they are snow-covered for more than nine months of the year. Arctic fox, northern deer, lemming, and many species of birds inhabit the islands.
