Lead in PETROL
The fallout from leaded petrol exhaust fumes not only pollutes the air we breathe with microscopic lead particles (amongst other pollutants), it is also responsible for adding to the lead content of household dust, soil and ceiling void dust in our homes. Because of their extra hand to mouth activity this dust is a major contamination pathway for small children, especially during renovation or demolition of pre 1970 buildings when the dust from areas such as roof voids or wall cavities is released. Add to this dust, the risk from lead paint that may also be disturbed during works, and you have a typical case of a young urban child - lead poisoned by the combination of sources of lead - paint, petrol and industry.
A recent Public Health Unit study found that children's blood lead levels rise 1 µg/dL for every 10,000 cars per day going past their childcare centre. (Cowie study, Sydney 1996).
Every gram of lead from petrol, put into the environment now is adding to the thousands of tons of lead from petrol which already contaminates our cities. So the lead petrol problem is not "going away" we're simply slowing down the rate of further contamination of our children's environment.
Over 100,000 (40%) cars in NSW could be using unleaded petrol (ULP), but are still using leaded. The NRMA recently published an article to help counter the lead additive manufacturers media campaigns which try to persuade people that leaded petrol is safer than unleaded. The levels of benzene in leaded and unleaded petrol in Australia are essentially the same. Overseas examples are not relevant to Australia and their situation is NOT OURS.
(Source: NRMA - Open Road March, 1996)
Check if your pre 1986 car is one that can immediately switch to ULP.
Since 1993 the Federal government has made $352 million from the leaded fuel tax which was levied because of the recognised health and environment risks attributable to lead. This money could be used to subsidise the more environmentally friendly MTBE (methyl tertiary butyl ether) additive and lead education campaigns. At the moment this lead fuel tax goes to consolidated revenue and less than 1% has been spent on dealing directly with lead.
Old cars would not have to be retired and the new MTBE fuel need not be any more expensive for consumers than leaded fuel is now.
They would just switch to the new product and everyone's lead levels would start to decrease accordingly. There is ample evidence to suggest that the general lead body burden of the population reduces in line with the reduction of lead in petrol. This has been shown to occur dramatically in other countries where lead has been removed from petrol.
Australian children are still dying and permanently injuring their health by sniffing petrol. Although sniffing any petrol is harmful to health, its the lead in petrol that kills or leaves petrol sniffers with permanent brain damage.Transport plans need updating to encourage public transport and reduce the overall need to travel by car. The gains made in Sydney's air quality by the introduction of ULP and catalytic converters are being overtaken by the increase in the number of cars and the distance traveled annually by each car. The amount of Australia's greenhouse gas emissions produced by motor vehicles is 21%. Britain has recently made radical changes to its transport policy to reduce dependence on the car, halving the budget for new roads.
The heavy metal pollution of Sydney Harbour is considered to be contributed to significantly by urban run off, including the substantial amount of leaded petrol exhaust particles which settle on roadways and are eventually washed into stormwater drains and then our Harbour. Sydney waterway sediments have mineable levels of lead and other heavy metals.
In August 1997 the new Clean Air Regulations were passed and leaded fuel can contain a maximum of 0.2 g/L. Unleaded petrol can contain 0.013 g/L. Shell half lead contains 0.1 g/L Australia is at risk of becoming the last developed country to ban lead in petrol. Leaded petrol was banned in Japan in 1986, Austria in 1990, Canada 1993, the US in 1995 and New Zealand in 1996 and yet Australias' Federal Government is considering waiting until 2010!
