tailieunhanh - REPORT of the CAS WORKING GROUP on ENVIRONMENTAL POLLUTION and ATMOSPHERIC CHEMISTRY

The study area is located on an ecosystem that is of low carrying capacity and as such this has necessitated excessive use of agro-chemicals to enhance productivity. The effects from these practices is that the chemicals find their way into the lake through runoff from the agricultural parcels of land. Because the land generally slopes towards the lake. Poor tillage practices often result in soil erosion and the loose soil is carried awash into the lake. All these result in increased eutrophication of the lake’s waters. The lake has no river outlet except for underground outlets in the southern. | WORLD METEOROLOGICAL ORGANIZATION GLOBAL ATMOSPHERE WATCH No. 151 REPORT of the CAS WORKING GROUP on ENVIRONMENTAL POLLUTION and ATMOSPHERIC CHEMISTRY GENEVA SWITZERLAND 18-19 MARCH 2003 NOVEMBER 2003 WORLD METEOROLOGICAL ORGANIZATION GLOBAL ATMOSPHERE WATCH No. 151 REPORT of the CAS WORKING GROUP on ENVIRONMENTAL POLLUTION and ATMOSPHERIC CHEMISTRY GENEVA SWITZERLAND 18-19 MARCH 2003 WMO TD No. 1181 Table of Contents 1.
