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 P1. 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.
The food waste water quality of sampling points of restaurant were collected within the Bilaspur city limit state Chhattisgarh India by determining some physicochemical parameter of the water samples using standard analytical techniques. The results of physicochemical parameters (pH, temperature, turbidity, conductivity, alkalinity, total dissolved solids, total suspended solids, total solids, Alkalinity and dissolved oxygen) revealed high variations in the concentrations of physicochemical parameters. Therefore, it is imperative that the water sources should be monitored regularly and be subjected to further treatments in order to reduce the concentrations of the few identified pollution indicators that may pose some dangers to the health of people living in this area. The aim of the present study is to develop a simpler direct uv- spectrophotometric method for the trace determination of lead with dithizone in the presence of inexpensive anionic micelles, such as sodium dodecyl sulphate (SDS), in aqueous solutions.
