BOFFINS are asking for more hi-tech equipment to help them check air quality.
A report to Kirklees Cabinet next Wednesday will outline need the need for £70,000 to buy three testing units to measure pollution.
Environmental Services staff want the new equipment to gauge the levels of nitrogen dioxide emissions from cars using Dewsbury Ring Road and a stretch of the M62 and check sulphur dioxide levels in Holmfirth.
Sulphur dioxide can come from burning fossil fuels such as coal and oil.
Three monitoring stations already exist in Kirklees. One is by Huddersfield's ring road at Shore Head, another is by Leeds Road at the junction with Old Fieldhouse Lane and the third is at Birstall Smithies.
Under the Environment Act 1995, local authorities must carry out regular checks on air quality.
Any area where purity does not reach certain levels must be declared an Air Quality Management Area.
An action plan then has to be put in place to cut down on emissions or pollutants.
