An evaluation of risk assessment framework for industrial accidents in India

Due to rapid industrialization, with high population density and constraints of land, it is expected that level of risks arising from the hazardous industries will increase in India in the coming decades. However, 30 years after the Bhopal accident (1984), except a few discrete regulations, there is as yet no integrated system for assessing and managing risks arising out of these hazardous industries in India. The gravity of aspects related to the management of industrial risk still remains crucially important. In particular, there is no standard guideline on risk analysis methodology, acceptability or tolerability criteria, nor is there an accident database or a risk reduction strategy for the areas where risk levels are already high. On top of this, there are technical and legislative gaps in the institutional framework to implement any of the above mentioned issues. With the backdrop of the Bhopal gas tragedy, the objective of this paper is therefore to evaluate the effectiveness of a comprehensive risk assessment framework for the emerging economy of India, in order to control and/or to reduce the risk level that exists. In this context, regulations and policies pertaining to industrial risk assessment were reviewed.

Passive sampling of selected endocrine disrupting compounds using polar organic chemical integrative samplers

Two types of polar organic chemical integrative samplers (pharmaceutical POCIS and pesticide POCIS) were examined for their sampling efficiency of selected endocrine disrupting compounds (EDCs). Laboratory-based calibration of POCISs was conducted by exposing them at high and low concentrations of 14 EDCs (4-alkyl-phenols, their ethoxylate oligomers, bisphenol A, selected estrogens and synthetic steroids) for different time periods. The kinetic studies showed an integrative uptake up to 28 days. The sampling rates for the individual compounds were obtained. The use of POCISs could result in an integrative approach to the quality status of the aquatic systems especially in the case of high variation of water concentrations of EDCs. The sampling efficiency of POCISs under various field conditions was assessed after their deployment in different aquatic environments.     

中国地表饮用水水源地有机类内分泌干扰物污染现况分析

有机类内分泌干扰物(EDCs)是一类对人类和生物内分泌系统产生干扰,并可造成其紊乱的特殊外来物质,对人类和生物健康有极大的危害.以与人类生活密切相关的地表饮用水水源地中的有机类EDCs为研究重点,对中国目前地表饮用水水源地EDCs污染状况、污染物种类及其来源及可能的污染途径进行了评述.目前,中国各地区地表饮用水水源地均有有机类EDCs检出.其中以有机氯农药六六六及其异构体、DDT及其代谢产物和多氯联苯检出率最高,且某些地区检测浓度相当高,主要来源是农药使用和污水排放.国内外对地表饮用水水源地EDCs突发污染事件的研究均较少,应引起高度重视.
