Abstract

The paper assessed major air pollutants resulting from gas flaring using rainwater. Rainwater samples were collected during the dry and wet seasons (2002/2003) and analyzed for physico-chemical characteristics such as, pH, TDS, conductivity, NO 3- , CO 3 2- and SO 4 2- . The mean values for the studied parameters during the dry season were pH (5.3) conductivity (20.50 µs/cm), TDS (17.13 mg/L), NO 3- (23 mg/L), S0 4 2- (1.41/ mg/L) and CO 3 2- (16.97 mg/L) and that for wet season were; pH (6.1), conductivity (19.60µs/cm), TDS (16.56mg/L), NO 3- (24mg/L), CO 3 2- (16.13mg/L) SO 4 2- (1.29mg/L). The mean levels of conductivity, TDS, and SO 4 2- were within statutory safe limits, while that of pH, CO 3 2- and NO 3- were above the safe limits specified by the Federal Ministry of Environment guidelines and standards for drinking water quality. Keywords : rainwater, gas flare, pollutants, monitoring, water quality Global Journal of Environmental Sciences Vol. 4(2) 2005: 123–126
利用雨水监测燃气燃烧产生的空气污染物
本文评估了利用雨水燃烧天然气所产生的主要空气污染物。在干湿季节(2002/2003)收集雨水样本,分析其理化特征,如pH、TDS、电导率、no3 -、co32 -和so42 -。枯水期研究参数的平均值分别为pH(5.3)、电导率(20.50µs/cm)、TDS (17.13 mg/L)、no3 - (23 mg/L)、s42 - (1.41/ mg/L)和co32 - (16.97 mg/L);pH(6.1),电导率(19.60µs/cm), TDS (16.56mg/L), no3 - (24mg/L), co32 - (16.13mg/L), so42 - (1.29mg/L)。电导率、TDS和so4.2 -的平均水平在法定安全范围内,而pH、co3.2 -和no3 -的平均水平高于联邦环境部饮用水质量指南和标准规定的安全范围。关键词:雨水,气体火炬,污染物,监测,水质,环境科学,Vol. 4(2), 2005: 123-126
