[求助] 求帮忙翻译一句话

It was reported that the concentrations of DBP and DEHP in plastics greenhouse soils were 2.5-3 times higher than the corrosponding data in soils from out-side of plastic film greenhouse.

与此相反,LgKow高的DEHP和DnHP的Ri值明显比DMP和DEP相应的(Ri值)低。...

再帮忙一下吧大神。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.

据报道,在塑料温室大棚内土壤的DBP和DEHP浓度是大棚外土壤的相应浓度的2.5到3倍。

在麻烦您一下,Given DBP with lgKow = 4.45, it is more apt to soil-air and soil-water exchanges, while DEHP is adsorbed easily by soil organic matter owing its higher lgKow (7.50).这句话是什么意思

lgKow应该是某种平衡常数的对数值吧 这个不清楚

在DBP的lgKow是4.45时 土气和土水交换更加好 DEHP更容易被土壤有机质(拥有更高的lgKow=7.50)吸收

专业词汇凑合一下吧 你应该比我清楚
