“…Besides, when the particle size was 0 ~ 45 and 75 ~ 150 µm, the average removal e ciency decreased from 74%, 81%, 90% and 92-66%, 74%, 82% and 85% at 10 cm, 20 cm, 40 cm and 50 cm depth in bioretention facility. The similar decreasing phenomenon on removal e ciency with the increase of particle size was also found in Shen's study (Shen et al 2021). In addition, the removal e ciency of naphthalene in the top 10cm reached a satisfactory level under the in uences of 0 ~ 45µm particles.…”

Particulate matter (PM), as an important carrier for carrying and transporting runoff pollutants, can signi cantly affect the behavior and removal e ciency of pollutants in bioretention facilities. In order to control the pollution caused by polycyclic aromatic hydrocarbons (PAHs) in bioretention facilities, the removal e ciency and migration characteristics of typical PAHs-naphthalene were systematically investigated under the in uences of PM. The results showed that the removal e ciency of naphthalene was 74% ~ 97% in bioretention facilities under the in uences of PM. With the higher naphthalene concentration, the lower rainfall return period, and the longer antecedent drying period, the removal e ciency of naphthalene in each media layer were higher. Furthermore, the PM in the runoff increased the naphthalene adsorption onto media in the rst 10 cm depth, which showed more than 80% removal e ciency and lower mobility of naphthalene. The removal e ciency of naphthalene was signi cantly higher (90% ~ 97%), when the particle size and concentration of PM were 0 ~ 45 µm and 500 mg/L, respectively. This study investigated the important role of PM for naphthalene removal in bioretention facilities, and provided effective guidelines for runoff pollution control, design of stormwater facilities, and assessment risk of PAHs.
