503种储运过程常见化学品的安全管控浓度的计算——基于化学品对藻类的环境风险评价
Calculation of safety-controlled concentration of 503 common chemicals in storage and transportation process: Based on the environmental risk assessment of algae by chemicals
-
摘要: 化学品在提高人们生活水平的同时会对生态环境,对化学品进行环境风险评价可有效地避免这一不利影响.本文通过对商值法进行逆向推导的方法,根据化学品对藻类的急性毒性EC50,通过相关公式计算出了两个评价指标,即慢性无可见有害作用水平NOAEL和预测无效应浓度PNEC,最终推导出503种化学品的安全管控浓度C控.系列化学品的C控不仅能够直接为企业提供可参照的化学品环境暴露管控标准,还能为企业的化学品科学管理工作提供数据支撑和决策支持.Abstract: Chemicals can promote people's living quality but also do harm to ecological environment simultaneously. However, the adverse impacts produced could be monitored by means of environmental risk assessment. In this paper, we determined the safety control concentrations (Ccontrol) of 503 compounds by calculating no observed adverse effect level (NOAEL) and predicted no-effect concentration (PNEC) from EC50 in acute toxicity test, according to the reverse derivation of the risk quotients method (RQ). Ccontrol can not only provide enterprises with the available environmental control standards but also provides support to scientific management on chemicals in enterprises.
