title: [Nitrates and nitrites content in the samples taken from the dug and drilled wells from the area of Podkarpacie region as a methemoglobinemia risk factors].
abstract: The aim of the study was to determine the nitrates and nitrites content in water samples taken from fourteen dug and drilled wells from the area of Podkarpacie, as well as a summary of the previously performed analysis. Private water intakes are not under the supervision of the State Sanitary Inspection. So in the case of exceeding the standards provided by the Regulation of the Minister of Health, regulating the requirements for drinking water, private water intakes can be a serious threat to the health of consumers. Particularly at risk are infants, in whom nitrates and especially nitrites can cause, among others, methemoglobinemia. The analysis was performed by ion chromatography method, making it possible to simultaneously determining the concentrations of nitrates and nitrites. As it turned out there was no presence of nitrites in the water of the tested wells. In five samples taken from the dug wells nitrates concentration exceeding the norm of 50 mg/L have been reported. In two cases, exceeding the nitrate concentrations were significant: 96.53 mg L and 204.65 mg/L.
