An innovative multiple regression analysis was used to evaluate metal/metalloid contamination in the surface sediments of a coastal lagoon. The concentrations of metals/metalloids were represented as a function of geochemical characteristics of the sediments (fine fraction, concentrations of organic carbon, Ca, Al, Mn) and distances between sampling points. The effect of distances on the concentrations were negligible for Li, Co, Ni, Ba, V, Cr, and only geochemical variables specific for each element explained its spatial variation. The concentrations of As, Cu, Zn and Pb were influenced by both geochemical and geographical distance variables, the latter representing the anthropogenic influence and the extent of transport of contaminants away from the upstream source. Enrichment of the sediment with Ba, As, Co, Cr and V was determined mainly by enrichment with Mn. The proposed approach is supplementary to the traditional utilization of enrichment factors, and is better suited for systems with anthropogenic influence.

创新的多元回归分析用于评估沿海泻湖表面沉积物中的金属/准金属污染。金属/准金属的浓度表示为沉​​积物的地球化学特征（细分数，有机碳，Ca，Al，Mn的浓度）和采样点之间的距离的函数。对于Li，Co，Ni，Ba，V，Cr，距离对浓度的影响可以忽略不计，只有每个元素特有的地球化学变量才能解释其空间变化。As，Cu，Zn和Pb的浓度受地球化学和地理距离变量的影响，后者代表了人为影响和污染物从上游源运出的程度。Ba，As，Co，Cr和V主要通过富集Mn来确定。所提出的方法是对传统的富集因子利用的补充，并且更适合于具有人为影响的系统。
