Diesel Emissions Classfied as Carcinogens by World Health Organization

Diesel Emissions Classfied as Carcinogens by World Health OrganizationBy 2015 Shenzhen officials are planning to transform the city’s existing diesel powered boilers to natural gas powered ones in line with a recent decision of the World Health Organization that has classified diesel exhaust as a carcinogen. Emissions for diesel vehicles, power plants and boilers are names as the primary air polluter in Shenzhen.

Recently a second west to east natural gas pipeline have started servicing Shenzhen in August that will supply the city with more than 4 billion of natural gas a year. The natural gas being transported to Shenzhen using the new pipeline will replace the diesel as fuel used in power plants and boilers and will reduce carbon dioxide emissions down to 7 million tons a year. But still the problem remains since clean diesel technology is still yet to be used.

Diesel exhaust has been classified by WHO as a probable carcinogenic in 1988. After a decade of reevaluation WHO elevated diesel classification to known carcinogen which declares the diesel fumes can cause bladder and lung cancer. Diesel fumes are also more carcinogenic than being exposed to secondhand smoke. When used in power plants or boilers diesel has the tendency to emit a mixture of particles, metals and gases that poses serious health problems.
