Periodically, both influent and eff

Periodically, both influent and effluent samples were collected and analyzed for PPCP concentrations. Differences between influent and effluent concentrations for active columns were attributed to PPCP biotransformation if they were greater than concentration differences observed across the abiotic control column.

結果 (中文) 1:

定期，进水和出水样品收集并对 PPCP 的浓度进行了分析。如果他们是大于跨非生物控制列观察到的浓度差异，进水和出水浓度为活动列之间的差异被归因于 PPCP 生物转化。

結果 (中文) 2:

每隔一段时间，无论进水和出水样本收集和PPCP浓度分析。进水和出水浓度之间的差异对主动列归因于PPCP生物转化，如果他们均大于整个非生物控制栏中观察到的浓度的差异。

結果 (中文) 3:

定期，进水和出水样品收集和分析的PPCP浓度。进水和出水的有源柱浓度是由于目前生物转化是否大于浓度的差异，观察在非生物控制塔之间的差异。
