The influence of varying concentrations of tannery wastewater was studied on cotton and brinjal plants. Tannery effluents were provided at 0%, 10%, 20%, 30%, 40% and 50% concentrations and data for various growth, biochemical and ion attributes were recorded successively at 20, 40 and 60 days after effluent treatments. Plant treated with different effluent exhibited a prominent reduction in growth traits of root and shoot at all three harvests. Maximum inhibition in growth was evident at 50% effluent application followed by 40% and 30% respectively. The increasing effluent concentrations inversely inhibited NRA activity and reduced total soluble proteins in both the plant species. A concentration dependant bioaccumulation of chromium and sodium was recorded while potassium and calcium ions exhibited reduction. Brinjal plants had higher Cr bioaccumulation (at all harvests) compared with cotton plants. In an overall assessment, irrigation with tannery effluents at all concentrations especially at 40% and 50% concentrations were toxic for both cotton and brinjal cultivation and it is further proposed that leather tannery effluent should not the used for irrigation of agricultural fields.

研究了不同浓度的制革废水对棉花和茄子厂的影响。制革厂废水的浓度为0％，10％，20％，30％，40％和50％，并在废水处理后20、40和60天连续记录了各种生长，生化和离子属性的数据。在所有三个收获期中，用不同的废水处理过的植物的根和芽的生长性状均显着降低。在污水处理量为50％时，生长的最大抑制作用明显，其次分别为40％和30％。增加的废水浓度反过来抑制了两种植物中的NRA活性并降低了总可溶性蛋白。记录了铬和钠的浓度依赖性生物累积，而钾和钙离子表现出还原。与棉花植物相比，茄子植物具​​有较高的Cr生物蓄积量（所有收成）。在总体评估中，使用所有浓度（尤其是40％和50％浓度）的制革废水对棉花和茄子种植均具有毒性，并且进一步建议皮革制革废水不应用于农业灌溉。
