Surveying the Environmental Biology Effects of Esfahan Factories on Zayandehrood Pollution

Abstract

Water is the key of national development. Wherever a spring has been dried out or a river has changed it s course, the area's people have migrated and have been scattered and th e area's civilization has lost its brilliance. Today, air po llution, global warming and ozone layer damage are as the problems of countries, but certainly in the next decade the shortage and p ollution of waters will be important issues of the world. The polluted waters are more dangerous in when they are used in agriculture. Be cause they infect plants and these plants are used in human and lives tock consumption in food chain. With the increasing population growt h and after that, the increase need to facilities and raw materials, human beings has started to do haste actions and wanted or unwanted destroyed his life basin. They try to overuse and capture his environm ent extremely, instead of having futurism approach in sustainable use of nature. This process includes Zayanderood recession, and caused its pollution after the transition from industrial and urban area s. Zayandehrood River in Isfahan is a vital artery of a living ecos ystem. Now is the location of disposal waste water of many cities, vi llages and existing industries. The central area of the province is an important industrial place, and its environmental situation has reached a critical stage. Not only a large number of pollution-generating industr ies are active in the city limits, but outside of the city and adjace nt districts Zayandehrood River, heavy industries like steel, Mo barakeh Steel and other tens great units pollute wild life. This article tries to study contaminant sources of Zayanderood and their severity, and determine and discuss the share of each of these re sources by major industrial centers located in areas. At the end, we represent suitable strategy.
