Intersex white suckers (Catostomus commersoni) were collected in Boulder Creek and the South Platte River downstream of wastewater treatment plant (WWTP) effluent but not at reference sites. Eighty-three percent of the 60 white suckers collected downstream of the Boulder WWTP in spring and fall were female compared to 45% upstream (n=33). Only female (n=16) and intersex white suckers (n=4) were collected in the South Platte River downstream of the Denver WWTP in the spring. Gonad deformities and delayed follicular maturation were noted in some white suckers in Boulder Creek and the South Platte River downstream of the WWTP effluents. Asynchronous ovarian development was found in some female white suckers downstream of the WWTP effluents, but not upstream. The types and extent of sexual disruption differed in each river studied.
雌雄间性的白亚口鱼（Catostomus commersoni）是在博尔德溪以及污水处理厂（WWTP）废水排放口下游的南普拉特河中采集到的，而在对照点未采集到。春季和秋季在博尔德污水处理厂下游采集的60条白亚口鱼中，83%为雌性，而上游的这一比例为45%（n = 33）。春季在丹佛污水处理厂下游的南普拉特河中仅采集到雌性（n = 16）和雌雄间性的白亚口鱼（n = 4）。在博尔德溪以及污水处理厂废水排放口下游的南普拉特河中的一些白亚口鱼身上发现了性腺畸形和卵泡成熟延迟的情况。在污水处理厂废水排放口下游的一些雌性白亚口鱼中发现了卵巢发育不同步的情况，但上游未发现。所研究的每条河流中性别干扰的类型和程度各不相同。
