When plants were considered, MLR mo

When plants were considered, MLR models indeed improved the
assessment of Cr and Ni accumulation, and highlighted that soil factors
such as pH, carbonates or total content of exchangeable cations may
play a significant role in the phyto availability of TE. However for the
other TE studied (As, Cd, Cu, Pb and Zn) the MLR did not give better
correlation coefficients than simpler models using only “available” soil
contents as explanatory variable. At the opposite for snails, considering
the soil parameters and/or plant contents in the regression models
improved the assessment of all TE, but As and Cu. As a rule, TE contents
in snail viscera were mostly correlated to plant contents, except for Cu.
This is in agreement with the results of Scheifler et al. (2006) who
showed that up to 90% of Cd accumulated by snails came from plants.
Internal TE contents in snails were also correlated to total contents
in soil (As, Cd, Cr) and/or to organic carbon (Cd), pH (Cr, Pb) and
carbonates (Cr).

当植物被认为时，确实改进 MLR 模型评估的铬和镍的积累，并强调该土壤因素如 ph 值、 碳酸盐或交换性阳离子的总含量可能在 TE 植物可用性发挥重大的作用。然而为其他 TE 研究 （砷、 镉、 铜、 铅和锌） 国土资源部不做得更好相关系数比用只有"可用"土壤的简单模型作为解释变量的内容。在对面的蜗牛，考虑土性参数和/或植物回归模型中的内容提高了评估的所有 TE，但作为和铜。作为一项规则，TE 内容在蜗牛内脏主要相关植物内容，除铜。这是一致结果的成等人 （2006 年） 的人显示，上升到 90%的 Cd 积累的蜗牛来自植物。蜗牛的内部 TE 含量也呈正向总含量（如，Cd，Cr) 土壤中有机碳 (Cd)、 ph 值 （铬、 铅） 和 （或) 和碳酸盐岩 (Cr)。
