There are two major problems with using leaded fuel.
1) Lead is extremely toxic, and causes mental retardation in children. Lead oxide from car exhaust accumulates in soil near roads, and children can get it on their hands from playing outside. They then ingest it, and it causes its damage.
2) Leaded gasoline ruins automobile catalytic converters. As a result of these two problems, lead in gasoline has been banned in the U.S. Other additives, such as methyl-tert-butyl ether (which is about to be banned), had to be used to improve gasoline's octane rating.

Cars emit carbon monoxide, nitrogen oxides and hydrocarbon. One of the causes of air poisoning is carbon monoxide, a very poisonous gas.

Diesel fuel is heavier and oilier than gasoline and when it was first used in cars during the oil crisis of the 1970s, people found their cars covered in soot. Indeed, diesel engines can emit a fair amount of nitrogen compounds and particulate matter as they burn diesel fuel. These facts combined to give diesel fuel a bad environmental name, even though it in fact emits lower amounts of carbon monoxide, hydrocarbons and carbon dioxide than does gasoline.

Some air pollutants and particulate matter from cars can be deposited on soil and surface waters where they enter the food chain; these substances can affect the reproductive, respiratory, immune and neurological systems of animals.
