Abstract: The Total Hydrocarbon Content (THC) in fresh surface waters and sediments of Oyigbo communities in Rivers State were determined using Gas Chromatography equipped with flame ionization detector (GCFID). Fresh surface water and sediments samples were taken from different locations in four communities namely; Umuagbai, Komkom, Egberu, and Izuoma. Result of the analysis revealed thus: mean of total hydrocarbon content in surface water and sediment as 7.869±1.166 mg/L and 12.01±0.856 mg/kg respectively. The total hydrocarbon content obtained from the various locations in surface water were Umuagbai (8.529±1.208 mg/L), Komkom (9.212±1.009 mg/L), Izuoma (6.701±1.670 mg/L), and Egberu (7.034±0.778 mg/L). In sediment the total hydrocarbon content obtained were; Umuagbai (12.62±0.585 mg/kg), Komkom (16.12±1.790 mg/kg), Izuoma (8.627±0.585 mg/kg), and Egberu (10.67±0.465 mg/kg). The result showed that the sediment had more total hydrocarbon content than the surface water, which is expected because the sediment is a reservoir for the water. The sediment and surface water THC levels were lower than the WHO permissible standard which indicates low risk level. The result showed some elevated concentration especially for the sediment sample which is noticed mostly in sediments and surface waters from Komkom community samples. It is recommended that usage of the water and even consumption of fish from the said river should be limited and anthropogenic actions within the study area should be limited.

Abstract: Following the evaluation of air quality at national level, the municipality of Bacau falls under the management regime I. The evaluation of air quality was carried out both by measurements at fixed points, with the help of measuring stations that are part of the National Air Quality Monitoring Network, central public authorities for environmental protection, as well as based on the results obtained from the mathematical modeling of the dispersion of pollutants emitted into the air. The main sources of air pollution in Bacau are represented by combustion in the energy sector, production processes, road traffic and individual heating systems. These sources require continuous monitoring to find the best possible techniques for minimizing and reducing the amount of pollutants released into the atmosphere. Emissions of nitrogen oxides (NOx) on the territory of Bacau municipality are released into the atmosphere especially in urban areas (inhabited areas) and on industrial platforms. Once released into the air, pollutants, due to the dispersion phenomenon, can be transported to different areas depending on the weather conditions present. The unfavorable combination of dispersal, weather conditions, topography of the region and pollutant concentrations can lead to exceeding limit values, with negative effects on human health.
