Financial Tribune - A study conducted by the Department of Environment on gasoline and diesel quality indicates both fuels sold in the country contain dangerous chemicals above acceptable standards, head of the Comprehensive Assessment Unit at the DoE said.

�Although there has been a decline in sulphur levels compared to summer, aromatic compounds and benzene are still above acceptable levels,� Zahra Samaee was quoted as saying by ISNA.

As part of the study, regular and premium (unleaded) gasoline samples were collected at random from 163 gas stations and the results revealed relatively high levels of aromatic hydrocarbons, she said.
