The toxic effects of p-xylene, 4-methylbenzyl alcohol, p-methyl benzaldehyde, and p-toluic acid on two marine microalgae (Phaeodactylum tricornutum Bohlin, and Skeletonema costatum) were investigated. p-Xylene was the most toxic to Pha. tricornutum with a 96 h EC value of 6.76 mg L. Based on the 96 h EC values for two microalgae, the toxicity of the four chemicals, in descending order, was: p-xylene, p-methyl benzaldehyde, 4-methylbenzyl alcohol, then p-toluic acid. The results showed that the toxicity of the transformed products of p-xylene was lower than that of p-xylene.
研究了对二甲苯、4-甲基苄醇、对甲基苯甲醛和对甲苯酸对两种海洋微藻（三角褐指藻和中肋骨条藻）的毒性作用。对二甲苯对三角褐指藻的毒性最大，96 小时 EC 值为 6.76 毫克/升。根据两种微藻的 96 小时 EC 值，这四种化学物质的毒性依次为：对二甲苯、对甲基苯甲醛、4-甲基苄醇，然后是对甲苯酸。结果表明，对二甲苯转化产物的毒性低于对二甲苯。
