为比较不同地区水样对HNS毒性效应的影响，研究了两种常见的HNS：对氯苯胺和丙烯酸丁酯对莱州湾和胶州湾海水养殖微拟球藻（Nannochloropsis oculatsis）的毒性效应。结果表明，对氯苯胺和丙烯酸丁酯对N.在两个水样中都有对氯苯胺抑制其净氧化速率和耗氧速率。丙烯酸丁酯抑制净氧合速率，而显着刺激耗氧速率。N的性能。对氯苯胺和丙烯酸丁酯投加量相同时，两种水样的浊度变化规律相同。N.与莱州湾相比，胶州湾海水中的藻细胞生长量增加了11.60%，耗氧率增加了26.91%，藻细胞生长量下降了16.83%。N.在胶州湾，0.5和2.0 mg L− 1对氯苯胺对oculatricated的抑制作用更为显著，而5 mg L− 1对氯苯胺则显著抑制。0 mg L-1的丙烯酸丁酯，与莱州湾相比。随着HNS浓度的增加，HNS对净氧合速率和耗氧速率的毒性作用均明显减弱。在两个海水样品中培养的微藻的生长抑制在0.5和5.0 mg L− 1对氯苯胺比在2.0 mg L− 1对氯苯胺更明显，在两个海水样品中培养的微藻的生长抑制在2.0和5.0 mg L− 1丙烯酸丁酯比在0.5 mg L− 1丙烯酸丁酯更明显。这些结果表明，对氯苯胺和丙烯酸丁酯对N.两种水样中的污染物对眼动电位均有影响。因此，需要对水样进行相应的研究，以提高未来HNS生态风险评价的准确性。
To compare the influence of water samples collected from various areas on toxic effect of HNS, we examined the toxic effect of two commonly found HNS: p-chloroaniline and butyl acrylate, onNannochloropsis oculatacultured in seawater collected from Laizhou bay and Jiaozhou bay (China). The results showed that both p-chloroaniline and butyl acrylate had significant toxic effect onN. oculatacultured in both water samples. P-chloroaniline inhibited its net oxygenation rate and oxygen consumption rate. Butyl acrylate inhibited the net oxygenation rate whereas significantly stimulated oxygen consumption rate. Performance ofN. oculatachanged between two water samples under same level of p-chloroaniline and butyl acrylate. The net oxygenation rate ofN. oculatacultured in the seawater from the Jiaozhou bay increased by 11.60 %, the oxygen consumption rate increased by 26.91 %, algae cell growth decreased by 16.83 %, compared to those from Laizhou bay. The Fv/Fm ofN. oculatacultured in Jiaozhou bay was more significantly inhibited at 0.5 and 2.0 mg L−1p-chloroaniline, while it was significantly inhibited at 5. 0 mg L−1of butyl acrylate, compared to those from Laizhou bay. Moreover, the toxic effect of both HNS on net oxygenation rate and oxygen consumption rate were significantly attenuated as the concentration increased. The growth inhibition of microalgae cultured in two seawater samples was more evident at 0.5 and 5.0 mg L−1p-chloroaniline than at 2.0 mg L−1p-chloroaniline,and the growth inhibition of microalgae cultured in two seawater samples was more evident at 2.0 and 5.0 mg L−1butyl acrylate than at 0.5 mg L−1butyl acrylate. These results indicated that toxic effect of p-chloroaniline and butyl acrylate on the growth ofN. oculatawas influenced by the pollutants in the two water samples. Consequently, a corresponding research on water sample is required in advance to increase accuracy of future ecological risk assessment of HNS.
