|Title:||Spatial and Seasonal Variability of Ambient Concentrations of Particulate Matter Around an Integrated Steel Plant: A Case Study|
|Keywords:||Spatial variability;Particulate matter;Meteorological parameters;Seasonal trend;Ambient air|
|Abstract:||The present study is focused on dispersion and transportation phenomenon of ambient particulates around an integrated steel plant. The dispersion and transportation of emitted particulate matter is greatly affected by various meteorological conditions such as wind speed, relative humidity, wind direction, temperature etc. Ambient air monitoring for levels of particulate matter in the vicinity of an integrated steel plant located in southeastern Chhattisgarh was carried out. The specific objectives are the determination of spatial and seasonal variability of levels of ambient particulates and their relationship with the selected meteorological parameters such as relative humidity (RH) and wind velocity (WV). Samples are collected in postrainy, winter and summer seasons of the year September 2000- June 2001. The results showed a marked seasonal trend and spatial variability of ambient particulate levels in the study area, which is highest in winter and lowest in summer. Seasonal variation in transportation pattern of PM10 (Particulate Matter, aerodynamic diameter ≤10µm) and SPM (Suspended Particulate Matter) is also observed. Ratios of PM10 to SPM and Pearson correlation coefficient values between both sizes or particulate matter and with selected meteorological parameters are also worked out. Relative humidity and wind velocity has shown an inverse relation with particulate deposition pattern.|
