SPATIAL AND TEMPORAL DISTRIBUTION OF NITRATES AND NITRITES IN THE FARMS’ WATER OF TIMIS COUNTY, ROMANIA: A CASE-STUDY

The present study aimed to investigate the spatial and temporal distribution of nitrates and nitrites in the farms’ water of Timis County. The sample for the study consisted of 4028 analysis bulletins of the nitrate and nitrite concentrations, measured in 41 farms and local water sources over two years (2016- 2242 and 2017- 1904 water samples) by the Surveillance Service, Public Health Direction, Timis. The data has been analysed with an observational case study of the spatial and temporal distribution of nitrate and nitrite concentrations in the farm water in Timis County. It has been found that the mean concentrations of nitrite and nitrate were lower than the standards, with a statistically significant difference (t=8.11, Sig.< 0.001) between the 2 years of study and with higher values recorded in 2016 than in 2017. A specific spatial distribution of the mean concentrations of these two substances was slightly high in old, polluted localities and pig farms in Timis County.
