MONITORING OF ENVIRONMENTAL POLLUTION AS A RESULT OF THE ACTIVITY OF REARING AND PRODUCTION OF SWINE.

The Danish company Premium Porc Group is the second largest producer of pork on the local market, the production activity being carried out in the 12 pig farms in Vrancea, Brăila, Constanta, Olt, Sibiu, and Brasov and since 2013 also within the Negreni farm in Olt County. The two lagoons for the storage and biological treatment of the liquid dejections have the bottoms and the soles waterproofed with geotextile membrane, and, to prevent the distribution of odours in the village, the dejections stored in these two ponds are permanently covered with a waterproof membrane. The solid dejections storage platform is located at a distance of 35 m from the two liquid dejections storage lagoons. To highlight how the activity of rearing and production of swine within Premium Porc Negreni Company from Olt County affects the quality of environmental factors, samples of air, rain water and groundwater were collected during 2018-2020 and subjected to analysis. The following quality indicators were analysed and monitored: NH3 and H2S emission (longlasting 24 h and short-term 30-minute averages), pollutant emissions from combustion gases from the natural gas thermal power plant (particulate, CO, NO2 and SO2) and the noise in the air; pH, total suspended particulates (TSM) and total petroleum hydrocarbons (THP) from meteoric/pluvial water discharged into the Negriöara stream; pH, nitrites and nitrates species in groundwater.
