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. 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. The positive relations between pH and HOCs were observed in the forest soils in Germany , and in the urban soil in Hong Kong . |

Vikelsoe 等l.[17] 提出DEHP每年大概以10cm/年速度下降, 因為根據(jù)數(shù)據(jù)顯示兩年內(nèi)最大值約為20cm. 這個結果得到來自未曾上下翻動區(qū)域的UL土壤中低Ri值的PAEs數(shù)據(jù)的確認,這個情況下,表層土壤中PAEs的來源可能是降水以及洪水。 與DBP相反,DEHP經(jīng)常可以在40-50cm深處找到,這也是PAEs中含量最高的一種, 分子量較小的DEP和DMP在土層深度超過40cm是測不到的,除了在PG土壤中有微量存在之外。在德國森林土壤中和香港市土壤中內(nèi)可以觀察到pH和HOCs之間有正相關性。 |
