Dispersion and emission patterns of NO 2 from gas flaring stations in the Niger Delta, Nigeria

摘要: The dispersion of nitrogen dioxide (NO2) emitted from gas flaring stacks affect the environment and human health negatively. This study assessed spatial temporal patterns NO2 emissions stations in Niger Delta between January 2017 December 2018. was measured using Aeroqual monitor. data concentrations were analysed SPSS for Windows. Hybrid Single Particle Lagrangian Integrated Trajectory Model adopted to predict stations. Results revealed that flare Rivers State highest varying 0.029 0.036 mg/m3 0.031 0.034 mg/m3 each station generally higher than 2018 by about 0.002 mg/m3. There an increase concentration 0.002 mg/m3 wet season over dry season. Increase temperature might have led (r = 0.047–0.377). An inverse relationship recorded relative humidity (r = − 0.005 − 0.412). Wind speed showed negative correlations with (r = − 0.148 − 0.139) weak positive correlation (r = 0.104–0.074) Many states Nigeria identified as receptors dispersed concluded people susceptible respiratory ailments should protect themselves impacts pollution Delta.
