  • Benzene is a recognized carcinogen. It is directly affected by the evaporation and combustion of gasoline and the release of exhaust gas into the atmosphere. Therefore, this indicator is restricted in the EU, UK, Australia and Russia gasoline standards, generally not more than 5% (v/v). According to Beijing local standard Precisely, the content of benzene is required to be not more than 1.0% by volume. However, as environmental requirements, governments and relevant agencies may also impose more stringent restrictions.
