East Lindsey District Council are required to review and assess local air quality. For detailed information on air quality in this area, please look at our Local Air Quality Management document.
The Air Quality Regulations 2000 set standards and objectives for seven pollutants that are associated with local air quality. The objectives are aimed at reducing the health effects of the pollutants to negligible levels. A brief outline of each of the pollutants can be found on this web site by clicking the links below.
o Benzene
o 1,3 butadiene
o Carbon monoxide
o Lead
o Nitrogen dioxide
o Particulates (PM10)
o Sulphur dioxide
1,3, BUTADIENE
Health effects
1,3 butadiene has been shown to be a genotoxic carcinogen, particularly associated with the induction of cancers of the lymphoid system and blood forming tissues. No absolutely safe level of the pollutant can be specified for ambient concentrations. The air quality objective set by the Government is a running annual mean of 1ppb.
Sources
The main source of atmospheric 1,3 butadiene is the combustion of petrol and diesel. The chemical arises from the combustion of olefins in these fuels. 1,3 butadiene also arises from a number of industrial processes such as the manufacture of synthetic rubber.
It has been estimated that in 1998 around 88% of national emissions of 1,3 butadiene arose from the road transport sector. Although the proportion of olefins in fuel has increased over the last decade there have been significant reductions in emissions from this sector due to the increased number of cars equipped with catalytic converters.
