Trace toxic elements concentrations (arsenic (As), boron (B), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), germanium (Ge), molybdenum (Mo), niobium (Nb), nickel (Ni), selenium (Se), zinc (Zn), yttrium (Y)) in sugar beet soils of Beni-Mellal region in Morocco were analyzed to evaluate their potential contamination level. The pollution was evaluated in three different sugar beet soils using enrichment factor (EF), geo-accumulation index (I_geo), contaminant factor (CF), potential contamination index (Cp), and pollution load index (PLI). The obtained results show that the studied agricultural soils were contaminated with various heavy metals and metalloids such as As (<8–34.5 mg kg⁻¹), Ba (186.5–241.0 mg kg⁻¹), B (73.0–103.7 mg kg⁻¹), Co (24.7–34.7 mg kg⁻¹), Ge (10.7–25.7 mg kg⁻¹), Nb (11.5–25.5 mg kg⁻¹), and Mo (32.3–35 5 mg kg⁻¹). The results of EF (99.04–2.60), CF (31.81–1.43) indices showed that these soils are heavily polluted with various elements (Mo> Ge> As> B > Co) suggesting their anthropogenic source. Moreover, these elements are higher than the limits proposed by the Canadian soil quality guidelines which oblige farmers to change their farming habits in order to protect and maintain ecological balance of the soil.

微量有毒元素浓度（砷（As），硼（B），镉（Cd），钴（Co），铬（Cr），铜（Cu），锗（Ge），钼（Mo），铌（Nb），分析了摩洛哥贝尼梅拉尔地区甜菜土壤中的镍（Ni），硒（Se），锌（Zn），钇（Y），以评估其潜在污染水平。使用富集因子（EF），地质累积指数（I _geo），污染因子（CF），潜在污染指数（Cp）和污染负荷指数（PLI）对三种不同的甜菜土壤的污染进行了评估。获得的结果表明，所研究的农业土壤受到各种重金属和准金属的污染，例如As（<8–34.5 mg kg ^-1），Ba（186.5–241.0 mg kg ^-1），B（73.0–103.7 mg kg^-1），钴（24.7-34.7 mg kg ^-1），锗（10.7-25.7 mg kg ^-1），铌（11.5-25.5 mg kg ^-1）和钼（32.3-35 5 mg kg ^-1）。EF（99.04–2.60），CF（31.81–1.43）指数的结果表明，这些土壤被各种元素（Mo> Ge> As> B> Co）严重污染​​，表明它们是人为来源。而且，这些元素高于加拿大土壤质量准则提出的限制，该准则迫使农民改变其耕作习惯，以保护和维持土壤的生态平衡。
