T／CSES 38-2021 重金属环境健康风险评估指南
《T/CSES 38-2021 重金属环境健康风险评估技术规范》由中国环境科学学会携手生态环境部华南所等机构共同制定，该规范首次全面整合了形态差异、生物有效性等关键参数，有效填补了如HJ 25.3等现有标准在金属污染物专项评估方面的空白。通过引入国际主流数据库（IRIS/ATSDR）的毒性参数，该标准实现了风险评估方法与国际标准的接轨。
在标准的第六章节中，明确要求使用生物有效性校正系数进行风险评估。例如，通过公式HQoral = ADDoral×IVBAoral/RfDoral计算风险商，其中，IVBA数据应优先采用体外模拟实验值（如PBET法）。
💟
附录A中整合了13种跨数据库的毒性参数，例如：
🚗
- 砷的经口致癌斜率因子SFo：1.5 (mg/kg·d)-1（IRIS）
✔️
- 铅的呼吸参考浓度RfC：0.15 μg/m3（OEHHA）
