In this study, to assess the distribution and fate of PAEs, specifically inside a full-scale horizontal subsurface flow constructed wetland, four PAEs including dimethyl phthalate (DMP), diethyl phthalate (DEP), di-n-butyl phthalate (DBP), and bis (2-ethylhexyl) phthalate (DEHP) were investigated. In e􀀏uent, PAEs concentration decreased 19.32%(DMP), 19.18%(DEP), 19.40%(DBP), and 48.56%(DEHP), respectively. Within the wetland, PAEs partitioned in water (0.18–1.12 􀀖g/L, 35.38–64.92%), soil (0.44–5.08 􀀖g/g, 1.02–31.33%), plant (0.68–48.6 􀀖g/g, 0.85–36.54%), air and biological transformation (2.72–33.21%) . The results indicated that soil and plant adsorption contributed to the majority of PAE removal, digesting DMP (19.32%), DEP (19.18%), DBP (19.40%), and DEHP (48.56%) in constructed wetlands. Moreover, the adsorption was a􀀋ected by both octanol/water partition coe􀀎cient (Kow ) and transpiration stream concentration factors (TSCF) . This work, for the first time, revealed the partition and fate of PAEs in constructed wetlands to the best of our knowledge.  \nKeywords: balance; constructed wetlands; full scale; phthalate acid esters  \n1. Introduction  \nPhthalate acid esters (PAEs) and phthalates are synthetic compounds used mainly as plasticizers to improve the flexibility, durability, and transparency of plastics [1] . As additives in numerous products, including coatings, coverings, insecticides, flooring, drainpipes, packaging, cosmetics, adhesives, and paints [2], they may migrate into the environment via various pathways including microbial transformation, microsomal metabolism, and sunlight exposure [3] . With strong chemical bond to the matrices of polymers, PAEs are persistent and found in almost all the environments, such as rivers [4], sediments [5], soils [6], sewage [7], air [8], biota [9], and even in human tissue [10] . Many pieces of evidence show the carcinogenic, teratogenic, and estrogenic e􀀋ects of PAEs [11] . Their potential risk to human and animal health has attracted increasing attention around the world. Accordingly, in 1977, six PAEs were listed as priority pollutants by the United States Environmental Protection Agency (US EPA) [12], including dimethyl phthalate (DMP), diethyl phthalate (DEP), di-n-butyl phthalate (DBP), bis (2-ethylhexyl) phthalate (DEHP), di-n-octyl phthalate, and butyl benzyl phthalate.
