摘要: Sex hormones are a group of potent endocrine disruptors that can be released into agricultural soils and sediment via wastewater discharge manure fertilization. Sorption represents critical determinant for the transport potential risks sex in environment. Therefore, this study reviewed sorption desorption mechanisms soil- sediment-water systems, summarized effects various factors on processes. A total 359 set data were collected from literature. mostly described by linear model. The magnitudes (logKoc) estrogens, androgens, progestins range 2.77–3.90, 2.55–4.18, 2.61–4.39, respectively. average logKoc values significantly correlated with their logKow (R2= 0.13, p < 0.05), while R2 much lower than those when fewer included analysis. In addition, Kd most OC% 0.16–0.99, but insignificantly particle size distribution surface area. These results indicated hydrophobic partitioning interaction other specific interactions responsible hormone uptake systems. systems also affected environmental variables, including pH, temperature, ionic strength. Future studies should focus coupled leaching-sorption processes manure-water-soil under field-scale conditions.
