The present work studied the pH, organic carbon, phosphorus (P), calcium (Ca), magnesium (Mg), and heavy metals Cu, Cr, Co and Pb in roadside agricultural soils of Jalandhar environs of Punjab, India. A total of 120 samples in triplicates were collected from different sites for assessment of heavy metal pollution. The mean values of Cu, Cr, Co and Pb were found below the permissible limits of Indian and Swedish soil limits. Principal component analysis (PCA) showed that heavy metals have different sources of origin. The results of contamination factor (CF), geoaccumulation index (I), degree of contamination (C) and potential ecological risk index (RI) showed low contamination and ecological risks of heavy metals in roadside agricultural soils, respectively. The maps of spatial analysis indicated that northern region of the study area is more polluted.
本研究分析了印度旁遮普邦贾朗达尔周边地区路边农业土壤的 pH 值、有机碳、磷（P）、钙（Ca）、镁（Mg）以及铜（Cu）、铬（Cr）、钴（Co）和铅（Pb）等重金属。共从不同地点采集了 120 个三重复样本，用于评估重金属污染。Cu、Cr、Co 和 Pb 的平均值均低于印度和瑞典土壤限量标准的允许限值。主成分分析（PCA）表明，重金属具有不同的来源。污染因子（CF）、地积累指数（I）、污染程度（C）和潜在生态风险指数（RI）的结果表明，路边农业土壤中的重金属污染程度较低，分别具有低生态风险。空间分析图表明，研究区北部污染程度较高。
