TAILIEUCHUNG - Determination of heavy metal levels in some moss species around thermic power stations

In our study, the chemical analysis related to the heavy metal pollution in some mosses grown near the thermic power stations which built close to Muğla and its environs, was carried out. | Tr.

Termik Santraller Civarındaki Bazı Karayosunlarında Ağır Metal Birikiminin Saptanması Özet: Çalışmamızda Muğla ve civarında kurulmuş olan termik santrallerin yakınlarında bulunan karayosunlarında kimyasal analizlerle ağır metal kirliliği tesbit edilmiştir. Anahtar Sözcükler: Tesbit, termik santral, karayosunu, ağır metal, kirlilik. Introduction As it is known environmental problems are among daily life problems in Turkey as in the world the last 20 years. Problems such that-caused by the destruction of forests, erosion, rapid increasing of population, distorting urbanization and decreasing green areas, distortion of shores, chemicals used in industry, nuclear energy and thermic power stations are the ones that their solutions are searched not only in our country but also in all over the world. Air, water and soil pollution related to the industrialization and urbanization are above the biological tolerance limits. Especially the overlapping of the settlements and industrial areas has been the reason for increasing air pollution in recent years. Heavy metals, such as zinc, lead, copper or nickel, are extremely toxic in very small amounts. When one or more of these elements in present in the environment at high concentrations, living organisms are subjected to strong natural selection for tolerance. Environmental contamination by metals exerts physological presures that are clearly too severe for survival of most species by means of .
