采用普通微板荧光检测法研究了腐殖酸对四溴双酚A（TBBPA）及其氧化降解产物2，5-二溴-1，4-苯醌的毒性影响（2，5-DBBQ）、2，5-二溴对苯二酚（2，5-DBHQ）、2，6-二溴苯醌（2，6-DBBQ）和2，6-二溴苯酚（2，6-DBP）对近头状拟基希氏藻（Pseudokirchneriella subcapitata）的毒力。EC 50值为：EC50（TBBPA）= 7 mg L−1，EC50（2，5-DBHQ）= 7 mg L−1，EC50（2，5-DBBQ）= 19 mg L−1，EC50（2，6-DBP）= 49 mg L−1，EC50（2，6-DBBQ）= 13 mg L−1。在HA存在下，化学品的毒性略低。以磷为氧化剂，研究了5，10，15，20-四（对磺酸基苯基）卟啉铁（Fe（III）-TPPS）与KHSO_5组成的仿生催化体系对TBBPA的降解毒性。subcapitata和莱茵衣藻Chlamyelomareinhardtii。
A micro-scale algal growth inhibition (μ-AGI) test using a common micro-plate based fluorometric detection was used to demonstrate the effects of humic substances (HSs) on the toxicity of tetrabromobisphenol A (TBBPA) and its oxidative decomposition products 2,5-dibromo-1,4-benzoquinone (2,5-DBBQ), 2,5-dibromohydroquinone (2,5-DBHQ), 2,6-dibromobenzoquinone (2,6-DBBQ), and 2,6-dibromophenol (2,6-DBP) toPseudokirchneriella subcapitata. The EC50values were: EC50(TBBPA)= 7 mg L−1, EC50(2,5-DBHQ)= 7 mg L−1, EC50(2,5-DBBQ)= 19 mg L−1, EC50(2,6-DBP)= 49 mg L−1, and EC50(2,6-DBBQ)= 13 mg L−1. The toxicity of the chemicals was slightly lower in the presence of HA. The toxicity of TBBPA decomposed by a biomimetic catalytic system consisting of iron (III) 5,10,15,20-tetrakis (p-sulfonatophenyl) porphyrin (Fe(III)-TPPS) and KHSO5was also evaluated usingP. subcapitataandChlamydomonas reinhardtii.
