Seasonal variation of PM10 around an upcoming airport
In this paper an attempt has been made to study the variation of PM10 at different receptor locations around an upcoming airport at Navi Mumbai, India. Air monitoring was carried out during all seasons in the base year i.e premonsoon, monsoon, post monsoon and winter season and results were analyzed. It was observed that overall yearly average concentrations of PM10 are lower than permissible lower limit of CPCB except two stations. It was found that PM10 concentrations were highest during winter season and PM10 is decreasing during pre monsoon, monsoon and monsoon seasons. Aviation affects the environment through the emission of pollutants from the aircrafts and other supporting airport infrastructure facilities, resulting on human health and the atmosphere. Emitted pollutants resulting from the aircrafts include green house gases and particulates matter that contribute to forcing of climate and gases and particulate matter that are harmful to human health. Navi Mumbai in the state of Maharashtra, India has been chosen as the study area. The PM10 concentrations were compared with the National Ambient Air Quality Standards (NAAQS).
