环境事件污染场地健康风险评估方法初步研究
HEALTH RISK ASSESSMENT FOR CONTAMINATEDSITES AFTER ENVIRONMENTAL ACCIDENT
摘要
Abstract
A method for health risk assessment is proposed to guide selection of remediation scheme for contaminated sites after environmental accident. The proposed method is based on the principle of priority control, to guide remediation plan. For pollution source identification, total amount and spread of pollutants are estimated according to types of accident, contaminants and site characteristics. For sampling scheme, a site-specific sampling principle is suggested, taking into consideration both type of accident and site situations. For exposure pathways selection, three pathways-inhalation, food ingestion and drinking of contaminated groundwater, are considered as key pathways. For risk characterization, risks of same contaminant under various exposure pathways and total risks of multiple contaminants could be ranked for risk control. The highest risks of contaminant and exposure pathways should be controlled with highest priority.关键词
