摘要
本研究于2007年5月和2011年5月在加拿大苏必利尔湖的Jackfish Bay研究了接触纸浆厂废水的棘鱼种群(Culaea inconstans)。小溪棘鱼被从污水接收处清除,大概是由于这段时间后缺氧。2007年和2011年,污水接收点的雌性性腺尺寸显著增大。2011年,与参考地点相比,暴露于污水的女性性腺发育显著提前;在三个不同的参考站点中,它们是第二成熟的。对7-乙氧基间苯甲醚- o -去乙基酶活性的分析显示,2007年,污水接收部位雌性的CYP1A诱导程度更高,2011年的CYP1A诱导程度显著更高。2007年,污水接收区雄鱼CYP1A诱导显著降低,2011年显著增强。接收环境中沉积物的化学评价显示树脂酸和多环芳烃(retene)含量升高。较高的条件因子和更成熟的性腺与较高的冬季和春季温度相一致,这些温度是由流出物或湖泊与溪流环境改变的。总的来说,对暴露于废水的小溪棘鱼的影响与先前研究中暴露于相同废水的白色吸盘的报道效果不一致。感谢CAWQ/ACQE (https://www.cawq.ca)的大力支持,本文已开放获取。
Effects of habitat and pulp and paper mill contamination on a population of brook stickleback (Culaea inconstans)
This study examined the responses of a population of brook stickleback (Culaea inconstans) exposed to pulp mill effluent at Jackfish Bay, Lake Superior, Canada, in May 2007 and May 2011. Brook stickleback were extirpated from the effluent-receiving site, presumably due to anoxia after this period. Females at the effluent-receiving site had significantly larger gonad sizes in 2007 and 2011. In 2011, effluent-exposed female gonadal development was significantly advanced when compared with reference sites; they were the second most mature when compared among three different reference sites. Analysis of 7-ethoxyresorufin-O-deethylase activity revealed that effluent-receiving site females had greater CYP1A induction in 2007 and significantly greater CYP1A induction in 2011. Effluent-receiving site males showed significantly reduced CYP1A induction in 2007 and significantly greater induction in 2011. Chemical evaluation of sediment from the receiving environment showed elevated levels of resin acids and the polycyclic aromatic hydrocarbon, retene. Higher condition factors and more mature gonads were consistent with higher winter and spring temperatures modified by effluent or by lake vs. stream environments. Overall, effects on effluent-exposed brook stickleback were not consistent with reported effects in white sucker exposed to the same effluent in previous studies.
