“…As these sites have shoe, A/C fan manufactures or car mat workshops nearby (Table S1), it is possible that they may constitute the main sources for Cr pollution in these sites. This is especially true as leathers used in shoe and car mat industry are significant sources for Cr pollution (Mwinyihija, 2010). The As distribution was different from that of Pb, Cd, and Cr and As concentrations did not vary with the distance of sampling site from C1, indicating sources other than e-waste processing activities are major contributors for As contamination in this region.…”

Freshwaters are not only used locally in many developing countries but they are often over exploited for domestic purposes, agriculture and disposal of industrial wastes which result in an overload of excess nutrients, harmful chemicals and heavy metals. Plant species together with sediments and water samples collected from eleven aquatic water bodies in the vicinity of industrial units in Kolkata were studied for their potential to uptake Pb, Cd and Cr under field conditions. Cd and Cr concentrations in the sediments were higher than background values considered to be toxic.Alternanthera philoxeroides and Eichhornia crassipes were the two invasive species present, with the former being more widely distributed. Among native plants, Ipomoea aquatica was the most abundant. Metal uptake in the plants differed among species, tissues and sites. Pb and Cd accumulation in root tissues for all plants in most sites suggested an exclusion strategy for metal tolerance. Since I. aquatica is widely consumed in many parts of SE Asia, its metal content should be checked before use since it was found to efficiently translocate both Pb and Cd from roots to shoots.The potential of A. philoxeroides as a metal excluder needs to be explored further since it translocates less to its shoots as compared to E. crassipes and I. aquatica.

“…Heavy metal contamination in water is one of the major health concerns around the globe, and this can cause severe health disorder not only for humans but also for every living creature [36][37][38][39]. There are different sources causing heavy metal pollution in water such as industrial waste; mining, pharmaceutical, textile, fertilizers, petrochemicals mostly contribute to heavy metal ions such as i.e., Zn, Ni, Cu, Cr, Pb, Cd, Ar, Mn ions [2,[40][41][42]. Different approaches have been made for the detection and removal of heavy metals for the water purification purpose such as bioremediation where bacteria as biosorbents as some of the microbes (i.e., Citrobacter, Pseudomonas, Streptomyces, Bacillus, etc.)…”

The presence of inorganic pollutants such as metal ions (Ni2+, Pb2+, Cr6+) in water, probably by long-term geochemical changes and from the effluents of various industries, causes diseases and disorders (e.g., cancer, neurodegenerative diseases, muscular dystrophy, hepatitis, and multiple sclerosis). Conventional methods for their removal are limited by technical and economic barriers. In biosorption, low-cost and efficient biomaterials are used for this purpose. In this study, Brassica Campestris stems from the agriculture waste and has been used for the removal of Ni2+, Cr6+ and Pb2+ ions from an aqueous solution containing all the ions. Effect of different parameters, e.g., pH, contact time, metal ion initial concentration, adsorbent dose, agitation rate and temperature were analyzed and optimized. The adsorbent worked well for removal of the Pb2+ and Cr6+ as compared to Ni2+. The atomic absorption spectrophotometer (AAS) and FTIR investigation of adsorbent before and after shows a clear difference in the adsorbent capability. The highest adsorption percentage was found at 98%, 91%, and 49% respectively, under the optimized parameters. Furthermore, the Langmuir isotherm was found better in fitting to the experimental data than that of the Freundlich isotherm.
