Benzene results - diffusion tube sampling

As part of the London-wide Benzene Monitoring Programme the London Borough of Richmond monitors benzene at 5 locations(pdf, 16KB).

London-Wide Environment Programme annual benzene reports

The main objective of the Benzene Monitoring Programme is to determine the ambient concentrations of benzene to which people are exposed to in urban areas. The programme was initiated in response to continuing concern that people living in urban areas are often exposed to elevated concentrations of benzene, which is a known human carcinogen. The reports include background information about benzene, sources of benzene, health effects, air quality standards and sampling results.

The historical reports consist of results solely within the Richmond Borough whilst the current reports include results from other participating London Boroughs. The results in the following report are quoted in ug/m3.

Benzene diffusion tube results

The following results are raw data from the laboratory analysis of the 5 benzene tubes located in the borough. The results run from January to December and include results from other related organic compounds i.e. toluene, ethyl benzene, M+p-Xylene and o-Xylene that were also sampled.

Benzene annual average concentration graph

The graph represents the annual average concentration of benzene from 2002 to 2011. The results indicate there has been a steady decrease in benzene concentrations over this monitoring period. In 2003 the annual average for the first time, fell below the 2010 air quality objective of 5ug/m3.
