The impacts of gas flaring on meteorological factors at Ibeno, Eket, Onna, Esit Eket and Umudike-Nigeria were investigated by measuring air quality parameters. The results show that the mean concentration of air parameters value were below Federal Environmental Protection Agency (FEPA) and United States Environmental Protection Agency (USEPA) National air quality standards with exception of carbon monoxide which exceeded the limit of 35 ppm in March at Ibeno. Concentration of air parameters at Umudike showed a similar trend to that of study locations at Eket, Ibeno, Esit Eket and Onna. Air quality parameters (Cl-, SPM and SO 2) were found to have positive correlation with vapour pressure, humidity and rainfall values in the study areas. It was also established that a positive correlation exits between NO 2 , H 2 S, SO 2 , SPM, chloride, carbon monoxide and wind speed relative humidity, temperature and vapour pressure in the study locations. Chloride and nitrate also have a positive relationship with wind speed in some of the study locations.

This study was carried out to determine the quality of rainwater from three different roofing materials (asbestos, aluminum and zinc) in Bodo Community of Rivers State, Nigeria. Samples were taken to the laboratory and analyzed using standard analytical procedures. The average result obtained ranged from 6.0-7.0, 40-66 µsi/cm, 18-48 mg/l, 32.52-86.67 mg/L, 0.06-3.18 mg/L, 5.02-13.76 mg/L, 2.79-5.02 mg/L, 0.16-0.77 mg/L, 0.27-5.79 mg/L, 0.24-0.62 mg/L and 0.03-4.08 mg/L for pH, conductivity, chloride, salinity, nitrate, sulphate, sodium, magnesium, calcium, iron and zinc respectively. Of interest were rainwater samples from asbestos roofing sheets which gave high calcium and magnesium content. Also, zinc roofing sheet gave high zinc and iron content compared to other roofing sheets. Physico-chemical properties and metal content of the harvested water from the roofing sheets were considerably different from those of control samples (water collected directly from raindrop). This could mean that the impinging of rain drop on the roof gradually erodes the roof material or could be as a result of anthropogenic inputs (deposits of pollutants in contact with roofing sheet) or geographical location. Considering the result of the analysis the harvested water could be put to other domestic use, as they can not be consumed directly. © JASEM http://dx.doi.org/10.4314/jasem.v19i4.15
