Vedclass · Answer

(D) Pollutants from vehicles can be reduced by several methods:$1$. Catalytic converters: These contain expensive metals like platinum,palladium,and rhodium as catalysts. They convert unburnt hydrocarbons into $CO_2$ and $H_2O$,and carbon monoxide $(CO)$ and nitric oxide $(NO)$ into less harmful $CO_2$ and $N_2$ gas.$2$. Proper maintenance: Regular servicing of vehicles ensures efficient combustion of fuel,thereby reducing the emission of harmful pollutants.$3$. Lead-free fuel: Using unleaded petrol or diesel prevents the release of lead into the atmosphere,which is a toxic heavy metal that can damage catalytic converters and cause health issues.
