Which option gives the best control strategies for Dioxins and Furans in the flue gas emitted from waste incineration facilities?
At a pressure of 1 atmosphere and temperature of 25\(^{\circ}\)C, 365 µg m\(^{-3}\) of a pollutant corresponds to a mixing ratio of 139 parts per billion (ppb). The atomic weights: C – 12, H – 1, O – 16, N – 14 and S – 32. Which one of the following options most closely represents the pollutant?
Stubble burning results in release of particulate matter, volatile organic compounds, oxides of nitrogen and sulfur, to name a few. A researcher is planning to use a conventional Gaussian dispersion model to estimate the contribution of stubble burning in a nearby state to air pollution in New Delhi. Choose the option(s) which could explain the possible limitations in this approach.
