Predicted particles (PM₁₀) levels for 2004

The map shows which areas are expected to be above the annual mean objective level (40ug/m³) for 2004.

The annual average PM₁₀ concentrations are predicted to be below the 2004 objective of 40µg/m³ across the whole Borough. 

Concentrations away from the roads tend to be between 27.5 and 30µg/m³. 

Along busy roads they rise to 32.5µg/m³ and on major roads 37.5µg/m³.

Annual mean particulate (PM₁₀) concentrations (40µg/m³) using using 2004 emissions and 1996 meteorological and background data.
