Assessment of Ammonia, Nitrates and Nitrites in Water Consumed by Animals in Local Households
The aim of this paper was to assess the quality of the water consumed by animals in rural households in terms of ammonia, nitrates and nitrites concentration. Thirty-seven water samples were collected from different sources (15 wells, 9 springs and 13 rivers and streams), all from Transylvania. The results were compared with the drinking water standards of the Law 7/2023 and statistically processed with the SPSS program, version 17. Significant differences (p < 0.05) were observed for ammonia, nitrites and nitrates. Ammonia concentration was significantly higher (p < 0.05) in rivers and streams than in wells and springs. For this parameter, no significant differences were observed between wells and springs (p > 0.05). Nitrites had a significantly higher concentration (p < 0.05) in
wells and rivers and streams than in springs, while nitrates had a significantly higher value in wells (p < 0.05).
