TIME TO REDUCE THE TRAFFIC! WE CANNOT MANAGE THE AIR POLLUTION

DAGS ATT DAEMPA TRAFIKEN! LUFTFOERORENINGARNA KLARAR VI INTE AV

Carbon monoxide mainly occurs in petrol exhaust. Its long-term effects such as increased frequency of heart attacks and effects on the central nervous system can be proved at concentrations as small as 5-10 ppm, i.e. along moderately trafficked roads. Oxides of nitrogen attack lung tissue and weaken the defence mechanism of the lungs. Nox are very active in acidification of precipitation. Sulphur dioxide has similar effects but only at concentrations much higher than those due to vehicular traffic. Hydrocarbons and nox are involved in reactions which form photochemical smog. Polyaromatics, particularly 3, 4-benzopyrene, are highly carcinogenic. The sizes of polyaromatic particles in diesel exhaust are particularly unfavourable from the cancer viewpoint. Problems due to polyaromatics will increase due to rise in diesel traffic. Lead is an environmental problem, but may be subordinate to polyaromatics and nox. Since cuts in one exhaust component usually result in an increase in some other component, traffic must be restricted, particularly in towns. Public transport must be made electric in the form of trolley-buses and trams, which are environmentally favourable. For the present, heavy traffic must be kept out of towns and parts of town centres must be set aside for pedestrians only. /TRRL/
