The present study was planned to explore the bioaccumulation potential of 23 plant species via bioaccumulation factor (BAf), metal accumulation index (MAI), translocation potential (Tf), and comprehensive bioconcentration index (CBCI) for seven heavy metals (cadmium, chromium, cobalt, copper, iron, manganese, and zinc). The studied plants, in the vicinity of ponds at Sahlon: site 1, Chahal Khurd: site 2, and Karnana: site 3 in Shaheed Bhagat Singh Nagar, Punjab (India), were Ageratum conyzoides (L.) L., Amaranthus spinosus L., Amaranthus viridis L., Brassica napus L., Cannabis sativa L., Dalbergia sissoo DC., Duranta repens L., Dysphania ambrosioides (L.) Mosyakin & Clemants, Ficus infectoria Roxb., Ficus palmata Forssk., Ficus religiosa L., Ipomoea carnea Jacq., Medicago polymorpha L., Melia azedarach L., Morus indica L., Malva rotundifolia L., Panicum virgatum L., Parthenium hysterophorus L., Dolichos lablab L., Ricinus communis L., Rumex dentatus L., Senna occidentalis (L.) Link, and Solanum nigrum L. BAf and Tf values showed high inter-site deviations for studied metals. MAI values were found to be more substantial in shoots as compared with that of roots of plants. Maximum CBCI values were observed for M. azedarach (0.626), M. indica (0.572), D. sissoo (0.497), and R. communis (0.474) for site 1; F. infectoria (0.629), R. communis (0.541), D. sissoo (0.483), F. palmata (0.457), and D. repens (0.448) for site 2; D. sissoo (0.681), F. religiosa (0.447), and R. communis (0.429) for site 3. Although, high bioaccumulation of individual metals was observed in herbs like C. sativa, M. polymorpha, and Amaranthus spp., cumulatively, trees were found to be the better bioaccumulators of heavy metals.
本研究旨在通过生物积累因子（BAf）、金属积累指数（MAI）、迁移潜力（Tf）和综合生物浓缩指数（CBCI）来探索 23 种植物物种对 7 种重金属（镉、铬、钴、铜、铁、锰和锌）的生物积累潜力。研究地点位于印度旁遮普邦的锡亚尔伯德辛格讷格尔的三个池塘附近：Sahlon（site 1）、Chahal Khurd（site 2）和 Karnana（site 3）。这些植物包括：Ag-eratum conyzoides（L.）L.、Amaranthus spinosus L.、Amaranthus viridis L.、Brassica napus L.、Cannabis sativa L.、Dalbergia sissoo DC.、Duranta repens L.、Dysphania ambrosioides（L.）Mosyakin & Clemants、Ficus infectoria Roxb.、Ficus palmata Forssk.、Ficus religiosa L.、Ipomoea carnea Jacq.、Medicago polymorpha L.、Melia azedarach L.、Morus indica L.、Malva rotundifolia L.、Panicum virgatum L.、Parthenium hysterophorus L.、Dolichos lablab L.、Ricinus communis L.、Rumex dentatus L.、Senna occidentalis（L.）Link 和 Solanum nigrum L. BAf 和 Tf 值在研究的金属方面显示出高的现场偏差。与植物根部相比，MAI 值在植物的茎中更高。在 3 个研究地点，最大的 CBCI 值出现在 M. azedarach（0.626）、M. indica（0.572）、D. sissoo（0.497）和 R. communis（0.474）；F. infectoria（0.629）、R. communis（0.541）、D. sissoo（0.483）、F. palmata（0.457）和 D. repens（0.448）；D. sissoo（0.681）、F. religiosa（0.447）和 R. communis（0.429）。尽管个别金属在草本植物（如 C. sativa、M. polymorpha 和 Amaranthus spp.）中的生物积累量较高，但总体而言，树木是重金属的更好的生物积累者。
