加热卷烟评估:加热卷烟烟支废弃物浸出液的环境风险

TS416; 为研究并了解加热卷烟烟支废弃物浸出液在环境中的环境风险,以加热卷烟烟支废弃物的浸出液为对象,开展了羊角月牙藻、大型溞、斑马鱼和蚯蚓的急性毒性实验,并研究其在环境中的固有生物降解性和关注成分烟碱在水生环境中斑马鱼体内的生物富集性.结果表明:①加热卷烟烟支废弃物浸出液对羊角月牙藻72 h的生长抑制效应浓度ErC50为1.843支/L,95％置信区间为1.522～2.210支/L;对大型溞48 h的急性活动抑制毒性EC50为0.665支/L,95％置信区间为0.601～0.736支/L;对斑马鱼96 h的急性毒性LC50是2.236支/L,98.4％置信区间为1.0～5.0支/L;②对...

Abstract TS416; 为研究并了解加热卷烟烟支废弃物浸出液在环境中的环境风险,以加热卷烟烟支废弃物的浸出液为对象,开展了羊角月牙藻、大型溞、斑马鱼和蚯蚓的急性毒性实验,并研究其在环境中的固有生物降解性和关注成分烟碱在水生环境中斑马鱼体内的生物富集性.结果表明:①加热卷烟烟支废弃物浸出液对羊角月牙藻72 h的生长抑制效应浓度ErC50为1.843支/L,95％置信区间为1.522～2.210支/L;对大型溞48 h的急性活动抑制毒性EC50为0.665支/L,95％置信区间为0.601～0.736支/L;对斑马鱼96 h的急性毒性LC50是2.236支/L,98.4％置信区间为1.0～5.0支/L;②对蚯蚓14 d的急性毒性LC50>60支/kg(人工土壤干质量);③28 d累计生物降解率为81.09％;④在0.05支/L水体中的烟碱对斑马鱼的生物富集系数BCF为4.74.本实验条件下,加热卷烟烟支废弃物的浸出液具有一定的水生生物急性毒性,但无明显的陆生生物急性毒性,且加热卷烟烟支废弃物浸出液具有固有生物降解性,加热卷烟烟支废弃物浸出液的关注成分烟碱富集性低,因此加热卷烟烟支废弃物浸出液的环境风险相对较小.
