ESTIMATION OF BORON CONCENTRATION IN SOME DRINKING WATER SAMPLES OF RURAL AREAS

Aim . Significant risks for human health may results from exposure to non pathogenic toxic contaminants that are often globally ubiquitous in waters from which drinking water is derived. In Moldova's rural areas (România) the wells are important water sources for the population. Material and methods . We have investigated the level of boron (B) in relation with other chemical parameters of water quality in 60 samples from 8 districts from Moldova (North-East România) in the period of 2005-2006 (nitrate, chloride, calcium, magnesium, total hardness, sodium, potassium, bicarbonate). Results . We have found out that the level of boron are below Romanian's sanitary norm, but there were noticed that well waters are polluted with nitrate. Conclusions . The presence of boron in drinking water sources in this territory is of natural origin. Thus, there is not a problem of aquifer pollution with boron.
