In the series without any soil amending substances, soil pollution with arsenic favoured accumulation of sodium in roots of yellow lupine, in aerial parts and roots of cocksfoot, but reduced the content of this element in aerial parts of maize and yellow lupine. their productivity. 7.5.1 Steel production. spread of infection to the plants, animals and human. for all of us to save ourselves and continuation of natural cycles in the ecosystem. Soil fertility depletion and soil quality decline have been threatening the ecological and economic sustainability of crop production. Assessing Soil Quality in Areas Affected by Sulfide Mining. Any degradation in the quality of soil can significantly produce many undesirable changes in the Control of pollution 8. 0 0000187793 00000 n The spatial distributions of contaminant metals (Hg, Pb, Zn, Cd, Cu) and a metalloid (As) in vegetable plots and paddy fields located near a large scale Pb/Zn smelter in Hunan province, China, were investigated. With its features like condensation and acceleration of polymerization, protection of organic molecules from disposition by the ultraviolet radiation, giving intermediate metal ions and phosphates, holding down osmotic potential of water, providing a relatively high ability to absorb the major cations in the same proportion with compounds of plants and animals and also providing rich solution in cations, the soil provides preliminary background for evolution, genesis and survival of life in the nature. Miller, J. T., Living in Environment (Traslated by Majid Makhdoum), Tehran University Printing and This suggests that at least other studies are necessary to preserve health in the inhabitants of this area. Bahram Soltani, Kambiz, An Introduction on Identification of Environment, Publications of the Department of The problem of pollution has always been a major issue all around the globe and the need for proper steps to prevent and overcome it has been increasing and has also found some voices in the recent times. Soil is an organic thin layer of earth’s crust, a living media. Higher rates of arsenic produced significantly negative influence on the content of sodium in the aforementioned plant organs. m��K[q�y�k������5�i���8�B������0�;'���0z4�����d�$d��8l��a%=�}�B���%�_;��W��� `Yq�O��6Y�J`\������5J�ÕT6e�f��(��Z,��ËD2�ñ��2�]I��� �n@ )0�)F�t�pn�q���%_w}�Ղ��=��\!u����VAgcp�P^�,>x��`J�ؘL3���J��[�k��&���� ��I�g��ӟ�}W�� After harvesting, soil pollution is reduced, such circumstances, volume is only reduced and the, which can be incinerated for producing thermal, decomposition and chemical reactions of combustion which is occurred, biomass and have shown that this method can have, Removal of Soil Oil Pollutions through Using, installations typically via transfer routes of these, plants and microorganisms along with them for clea, depends on the climatic condition of the region, type, Future of Phytoremediation Technique in Cont, application of fast-grown plants with high biomass and high abso, more suitable in comparison with the direct incineratio, preventing pollution of resources especially soil, [1] Bavandi, Bijan, Ecosystem, Publications of the, [4] Commoner, Bari, Human and Environment (, Consequences, Corrective, Symposium, National Academy, [9] Goldman, Marshall I., Environmental Disruption. The present paper is a mini review of the increasing soil pollution in the environment and the The most unambiguous effect of neutralizing substances was determined for cocksfoot and spring barley, where they depressed the content of sodium in aerial parts of cocksfoot and in spring barley grain, while raising it in roots of these plants. Results from a potential ecological risk assessment indicated high risk associated with the soil within a 4 km radius, with the contribution for each contaminant calculated as follows: Cd (70.0%), Hg (19.4%), Pb (4.8%), As (3.0%), Cu (1.7%) and Zn (1.1%). The health of all life forms is associated with the health of soil.
