Bioinorganic chemistry is found as a sizzling field in today’s era. It deals with chemistry amongst the heavy metals with natural resources, i.e., air, soil, water, plant byproducts (foods), and environmental essences. The aim of this research is to determine the concentration of heavy metals present in the food waste water sample and to study the environmental effects of metal ion concentration. To conduct the research work, the physicochemical parameters and levels of five heavy metals of food waste water samples were collected from five sampling points of renowned hotels, restaurants, canteens, and confectionaries of a state of India and assessed using the standard analytical procedure. Sampling was carried out from January 2017 up to December 2017. The physicochemical parameters were determined such as pH, temperature, turbidity, conductivity, total dissolved solids, total suspended solids, total alkalinity, biological oxygen demand, chemical oxygen demand, dissolved oxygen, total organic carbon, sulphate, nitrate, and phosphate. The heavy metal concentration was determined by using the UV-spectrophotometer, and the results were compared with the standards prescribed by the WHO, BIS, ICMR, and municipal authorities. The results obtained in the physicochemical analysis revealed that a few parameters were found beyond limits, and the metal ion concentration (iron and zinc) results were found above the permissible limits set by the CPCB (Central Pollution Control Board), ICMR, BIS, and World Health Organization (WHO), most especially, effluent from point . It was concluded that all the effluents required further treatment before releasing them into the water body or land to prevent pollution. The obtained results reveal that waste water used for irrigation and farming of nearby areas and water drained from restaurant kitchens were considerably polluted and not suitable for aquatic organisms, irrigation, and agricultural purposes.

环境影响测定食品废水中的理化参数和重金属含量。

在当今时代，生物无机化学是一个炙手可热的领域。它处理具有自然资源的重金属中的化学成分，这些自然资源包括空气，土壤，水，植物副产品（食品）和环境要素。这项研究的目的是确定食品废水样品中重金属的浓度，并研究金属离子浓度对环境的影响。为了开展研究工作，从印度某州的著名酒店，饭店，食堂和糖果店的五个采样点收集了五种食物废水水样的理化参数和含量，并使用标准分析程序进行了评估。从2017年1月至2017年12月进行采样。确定了理化参数，例如pH，温度，浊度，电导率，总溶解固体，总悬浮固体，总碱度，生物需氧量，化学需氧量，溶解氧，总有机碳，硫酸盐，硝酸盐和磷酸盐。使用紫外分光光度计测定重金属浓度，并将结果与​​WHO，BIS，ICMR和市政当局规定的标准进行比较。在理化分析中获得的结果表明，发现一些参数超出了限制，并且发现金属离子浓度（铁和锌）的结果超出了CPCB（中央污染控制委员会），ICMR，BIS和世界卫生组织（WHO），尤其是从点 总有机碳，硫酸盐，硝酸盐和磷酸盐。使用紫外分光光度计测定重金属浓度，并将结果与​​WHO，BIS，ICMR和市政当局规定的标准进行比较。在理化分析中获得的结果表明，发现一些参数超出了限制，并且发现金属离子浓度（铁和锌）的结果超出了CPCB（中央污染控制委员会），ICMR，BIS和世界卫生组织（WHO），尤其是从点 总有机碳，硫酸盐，硝酸盐和磷酸盐。使用紫外分光光度计测定重金属浓度，并将结果与​​WHO，BIS，ICMR和市政当局规定的标准进行比较。在理化分析中获得的结果表明，发现一些参数超出了限制，并且发现金属离子浓度（铁和锌）的结果超出了CPCB（中央污染控制委员会），ICMR，BIS和世界卫生组织（WHO），尤其是从点。结论是所有废水在排放到水体或土地之前都需要进一步处理以防止污染。所得结果表明，用于附近地区的灌溉和耕作的废水以及从餐厅厨房排出的废水被严重污染，不适合水生生物，灌溉和农业用途。
