Accumulation of total trace metals due to rapid urbanization in microtidal zone of Pallikaranai marsh, South of Chennai, India 总被引:1,自引:0,他引:1
M. Jayaprakash B. Urban P. M. Velmurugan S. Srinivasalu 《Environmental monitoring and assessment》2010,170(1-4):609-629
The article presents the results for enrichment of total trace metals (TTMs) from Pallikaranai salt marsh in South Chennai, a metropolis on the southeast coast of India. TTMs Fe, Mn, Cr, Cu, Ni, Co, Pb, Zn, Cd, Sr, V, and Hg along with sediment texture, OC, and CaCO3 were analyzed in 36 surface sediments collected during August 2008 to recognize and observe the input of TTMs in the marsh from various sources in the city limits. In view of the rapid urbanization and industrialization in Chennai City, especially on the southern side, uncontrolled input of sewage, garbage, and industrial effluents into the Pallikaranai marsh land, the elevated concentrations are not surprising. The level of enrichment of TTMs has also increased by 20% to 60% for most of the elements when compared with all other ecosystems in the world as well as the nearby area. The results also indicate that the marshy region is more heavily contaminated with Cd, Hg, Cr, Cu, Ni, Pb, and Zn than other regions on the southeast coast of India. The Enrichment Factor, Contamination Factor, and I geo indexes are calculated, and these values are useful to assess the degree of pollution in sediments. The spatial distributions of TTMs are also controlled by other factors like geochemical, precipitation, and flocculation of particulate substances in the marsh. The results of the present study suggest the need for a regular monitoring and management program which will help to improve the quality of Pallikaranai pristine marsh land. 相似文献

An Experiment in Participative Environmental Decision Making 总被引:2,自引:0,他引:2
Summary The paper presents a method of participatory decision-making involving the authorities at local level, experts and the public.
It studies how to solve the problems caused by the heterogeneity of the parties taking part in the decision-making process.
The method builds on mutual learning and consideration among the participants following a systematic approach led by a moderator.
The method was tested at a workshop simulating a real-life situation. The test case studied at the workshop was the problem
of identifying the best site for a low and intermediate level radioactive waste repository among three alternatives. The learning
phase was the Krško Nuclear Power Plant cooling problem. The results show that the participants were able to reach agreement
on the prioritisation of the alternatives and to end up with suprisingly complex and fully reasonable decision models. We
believe that this was achieved particularly due to the well defined procedure that guided the decision-making process, and
the ability of all participants to see the influence of their views on the decision model. 相似文献
