A) If we burn any fossil fuel in the presence of insufficient supply of oxygen
carbon monoxide and unburnt hydrocarbons released into the atmosphere
which is harmful for human health and if we burn any fossil fuel in the presence of sufficient supply of oxygen it release Carbon dioxide which absorb harmful radiation which is emitted by the earth which increase temperature of earth and cause Global Warming.
B) 
Dust contain plant pollen,burnt particles,fine soil particle,smoke and many other materials which pollute our environment.If we see our environment after rain its seem clear than before rain because dust particle settle down due to drop of rain.And its also cause difficulty to breath in that environment.So we can say that dust is a pollutant
