Vikelsoe et al.[17] suggested that a downward movement for DEHP occurred approximately 10 cm year-1 because the profile maximum occurred 20 cm deeper in 2 years.
This result was confirmed by the data in UL soil with relative low Ri values of PAEs, where no vertical mixing has taken place, and atmospheric precipitation and/or floods may be responsible for presences of PAEs in surface soil.

还有这一句Conversely with DBP and DEHP frequently founded at 40-50 cm depth, which are mostly predominant of PAEs, DEP and DMP with light molecular weight were not detected in the soils deeper than 40 cm, except for DEP with trace amount in PG soil

However, a fraction of DEP founded at 40-50 cm depth in PG soil also reflected that the concentration of PAEs in surface soil was an important factor on the PAEs distribution in soil profiles.
