Recent evidence has shown that humans metabolize benzene more efficiently at environmental air concentrations than at concentrations > 1 ppm. This led the researchers to speculate that an unidentified metabolic pathway was mainly responsible for benzene metabolism at ambient levels.
The International Fuel Quality Center recently released a ranking of the top 100 countries based on the lowest benzene limits in gasoline. Colombia was at the top of the ranking with the lowest limit, followed by Canada and Luxembourg.
Draft new EU legislation that would limit harmful vapour emissions from petrol pumps was proposed on 4 December by the European Commission. Petrol vapour contains benzene, which is known to cause cancer, and contributes to the formation of ground-level ozone, one of the air pollutants that is most damaging to human health and the environment and which also contributes to global climate change.
Cancer is the second leading cause of death among U.S. children with few known risk factors. There is increasing interest in the role of air pollutants, including benzene and 1,3-butadiene, in the etiology of childhood cancers.
Petrochemicals are hydrocarbons, obtained from naturally occurring raw materials viz. petroleum, natural gas, coal etc. Coal was initially the basic raw material for organic chemical industry. However the basic feedstock has changed recently from coal to petroleum. This is attributed to the recent innovation and technological advance in the field of chemical industry based on petroleum feedstock.
vehicular pollution is common to most metros. A Kolkata-specific study has highlighted how vehicles in Kolkata emit cancer-causing volatile organic compounds (vocs). The study noted that specific
Benzene is a human carcinogen. Exposure to benzene occurs in occupational and environmental settings. The researcher evaluated data from a cohort of 1,845 rubber hydrochloride workers. Benzene exposure
A Kannan has been feeling dizzy with fever for days, his limbs are shaky. He has come to the government hospital in Tamil Nadu's coastal Cuddalore town with others from nearby Kudi
Benzene exposure from vehicular sources and its health impact are relatively unexplored in India. We have investigated in this study hematology and lymphocyte subsets of 25 petrol pump attendants, 25 automobile service station workers and 35 controls matched for age, sex and socioeconomic conditions.
despite petrol's benzene content being lowered from 3 per cent to 1 per cent in 2000-2001, there has been no significant effect on the current ambient levels of this carcinogenic chemical.
