2、研究结果表明:在有风模式中,鸟类的不可接受风险范围最远可达下风向7km,蛙类的不可接受风险最远可达下风向 27km。大部分敏感点的蛙类急性暴露剂量都超标,处于不可接受风险水平;80%的敏感点的鸟类处于不可接受风险水平。根据风险评价结果,提出从防范措施、应急预案、环境监测和生态补偿 4个方面制定区域生态风险管理措施。该区域生态环境风险评价研究为同类型区域生态环境风险评价提供借鉴作用。【1oM】危险化学品;区域生态环境;风险评价;风险受体;评价终点;生态补偿RegionalEco-environmentalRiskAssessmentBasedontheStorageofDangerousChem
