摘要：Environmental impact assessment of liquid rocket motor exhaust obtained due to mainly liquid propellant combustion have been highlighted. Exhaust product analysis has been carried out theoretically by computer software NASA CEC -71 to identify toxic emissions of rocket combustion. In the present study a high volume Air Samplers (APM-430) was deployed at predetermined locations near launch pad for collection of toxic exhausts using liquid absorbents during actual missile launch. The collected samples were analyzed subsequently for quantitative estimation of suspended particulate matter (SPM), oxides of nitrogen (NOX) and oxides of sulphur (SOX) etc. with the help of a spectrophotometer. The dispersion pattern of the various toxic gases verses time and distance has also been monitored.
