RISK TO HUMAN HEALTH CAUSED BY NON CONDITIONAL DRINKING WATER

Abstract

Drinking water quality is one of the key factors that may cause harmful effects to health, especially during lasting continuous consumption. This report analyzes information on current state of some basic health factors for Chernivtsi citizens depending on their place of living and consuming drinking water from local wells. Non quality contact medium risk analysis and some peculiarities of this function application for problem of kinetic modelling are under discussion as well. The analysis of risk increase effects during natural nitrification process on the basis of two kinetic models of the nitrification cycle is studied. The analysis is focused on two cases: when enzymes concentrations are constant and when nitrifying bacteria grow. The numerical solution of kinetic model and geo-informatical analysis are used to explain possible causes of high risk values and oncological diseases occurrences that may be caused by nitrate contamination. The question: why nitrates pollution level correlates with oncological pathology is under discussion of the study. An attempt to forecast health quality factors for citizens taking into consideration nitrogen intermediates is made. A simple kinetic model of immune status of people under chemical pollution of drinking water is considered as well. A comparison of the results of simulation with real statistic illnesses data and contaminant dispersion is the subject of the study.
