Naphthalene, originating from anthropogenic activities, is a toxic contaminant commonly found in urban stormwater runoff. This study investigated the adsorption and desorption potential of naphthalene in a bioretention cell soil at various temperatures and salinities representative of cold-climate winter conditions. In all experiments, more than 70% of the initially added naphthalene was adsorbed on the bioretention soil at equilibrium. Temperature and salinity showed little but inconsistent effects on the adsorption of naphthalene, and the adsorption of naphthalene was partially reversible under some conditions, e.g., at higher temperature. Despite its reversibility, naphthalene desorption may allow for the regeneration of the sorption capacity of the soil media, and transformation processes to take place. Overall, these results suggest that bioretention cells are able to temporarily retain a large portion of the inflowing naphthalene over short periods.

寒冷气候条件下生物滞留细胞中萘的吸附和解吸

萘源自人为活动,是一种常见于城市雨水径流中的有毒污染物。本研究调查了在代表寒冷气候冬季条件的各种温度和盐度下,萘在生物滞留细胞土壤中的吸附和解吸潜力。在所有实验中,超过 70% 的最初添加的萘在平衡状态下被吸附在生物滞留土壤上。温度和盐度对萘吸附的影响很小但不一致,并且在某些条件下,例如在较高温度下,萘的吸附是部分可逆的。尽管具有可逆性,但萘解吸可能允许土壤介质的吸附能力再生,并发生转化过程。全面的,
