HEALTH RISK ASSESSMENT TO ZINC IN DRINKING WATER OF RURAL RESIDENTS LIVING IN BHUSAWAL CITY, MAHARASHTRA (INDIA)
In context to human health these trace elements are important and inadequate daily consumption can impair health, these can be fulfilled by parallel consumption of water. Zinc plays important role in first line defense (Immunity), taste sensation, secretion of gastric enzymes and wound healing. Zinc is essential for proper growth, normal spermatogenesis, wound healing, taste sensation and secretion of gastric enzymes and inadequate Zinc intake is associated with retardation of growth in children, coronary artery disease, poor wound healing, high blood cholesterol, low blood sugar level and diarrhea in pediatrics (Lingamaneni P et al., 2015). The acceptable safe limits of Zinc content in drinking water according to World Health Organization is 5-15 mg/L (World Health Organization Guidelines for Drinking Water Quality, 1993).
Table no. 2: List of adequate intake of Zinc in different group of population
Daily requirement of zinc varies in different age groups from 5 to 15 mg/day (Prasad A et al., 2013). As food is a primary source but adequate intake can be fulfilled by parallel consumption of water.
Quantitative estimation of Zinc in water samples from Natural sources Of Bhusawal (21.0455° N, 75.8011° E) region showed that concentration of zinc is within acceptable safe limits as per WHO guidelines of Zinc and Concentration of Zinc Was Found High in water samples of Bore well as compared to well and river, therefore from the study it can be suggested that Population residing in Bhusawal region consuming water from Bore well are getting more Zinc as compared to Population Consuming water from Well and river and Population Consuming water from Bore well will be less prone to Zinc deficiency and other diseases associated with Zinc deficiency.
