在分析国内外危险废物分级管理经验的基础上,结合健康风险的评估步骤,提出了基于全过程危险废物污染物释放情景的精细化-动态健康风险评价方法。充分考虑处理利用工艺、企业管理水平等因素对于危险废物中污染物释放概率和能力的影响,并基于污染物向环境介质的迁移转化,定量评估危险废物的健康风险。基于危险废物污染特性数据库和事故情景数据库,结合全过程信息采集技术,构建危险废物分级分类管理平台,进行涉废企业的风险级别划分,实施差异化管理,形成更加科学有效的危险废物全过程精细化管理体系。 相似文献

This research had been conducted during year 2012 to review existing data on hospital waste management for some of Khartoum town hospitals and to try to produce appropriate proposals acceptable for waste management and final treatment methods. The overall status of hospital waste management in Khartoum has been assessed through direct visits and designated questionnaires. Eight main hospitals were covered in the study with an overall bed capacity of 2,978. The current waste management practice observed at all studied hospitals was that most of waste, office, general, food, construction debris, and hazardous chemical materials were all mixed together as they are generated, collected, and finally disposed of. Only a small portion of waste in some hospitals (part of potentially infectious, body parts, and sharps) are collected separately and treated in a central incinerator. The estimated value of per bed generation rate in the studied hospitals was found to be 0.87 kg/day, which lies within the range for the low-income countries. In all studied hospitals, it was found that workers were working under very poor unsafe conditions with very low salaries ($35 to $45 per month on average). About 90 % were completely illiterate or had very low education levels. At the national level, no laws considering hospital waste, or even hazardous waste, were found; only some federal general environmental regulations and some procedures from town and city localities for controlling general municipal waste exist. At the hospital level, no policies or rules were found, except in the radiotherapy center, where they manage radioactive wastes under the laws of the Sudanese Atomic Agency. Urgent actions are needed for the remediation and prevention of hazards associated with this type of waste. 相似文献

One of India's major concerns is the increasing level of land pollution largely due to the uncontrolled disposal of industrialsolid and hazardous waste. With rapid industrialization, thegeneration of industrial solid and hazardous waste has increasedappreciably and the nature of waste generated has become complex.Their impacts on the ecological bodies are noticeable. The article describes the details of studies conducted using Toxicity Characteristics Leaching Procedure, to estimate the toxicity effects of the metals viz., chromium, zinc, manganese,iron, nickel, cobalt and copper by the Zero Headspace Extractorfor the sludges generated from effluent treatment plant of steeltube, wire and plating industries on environment constituentslike groundwater, surface water and land. Toxicity Characteristics Leaching Procedure determines the mobility of organic and inorganic analytes of liquid, solid or multiphase waste from hazardous solid wastes in the form of primary and secondary extracts. These extracts are mixed in equal volumeproportion and analyzed by Direct Reading 2000 spectrophotometer.The amount of heavy metals observed during the studies in theleachates were found and the results were compared with HazardousWaste categories as per Indian Standards, TCLP regulatory limitsgiven by United States Environment Protection Agency (USEPA) andGermany Leachate Quality Standards and it was observed that theywere on higher side, needing a proper preventive concept of sludge management including handling, treatment, recovery and disposal. 相似文献
