A couple is taking legal action against a housing association over claims their home was built on contaminated land.
Angela and Robert McManus, from the Watling Street estate in Motherwell, North Lanarkshire, say the site they live on was not decontaminated properly after it fell out of industrial use.
The couple think the land's previous incarnation as a location for factories and industrial plants is behind health issues at the estate.
The former site had handled and processed metals and chemicals, and materials said to have been found at the site include trichloroethylene (TCE), tetrachloroethylene (PCE) polychloranated biphenols and polyaromatic hydrocarbons.
Mrs McManus has lived on the site since the houses were built and Mr McManus moved there in 2004.
An action has now been launched on behalf of Mr and Mrs McManus by Collins Solicitors against Lanarkshire Housing Association (LHA). The firm hope it will result in a "test case" to establish whether there are harmful substances at the site and if they are causing health problems.
Des Collins, senior partner of Collins Solicitors, said: "Whilst it is important to ask why the site was not properly remediated before the houses were built, the much more pressing issue is to find an immediate solution to the ongoing health problems.
"Site investigations have been ongoing for over two years. The most recent survey commissioned by the residents revealed levels of neuro-toxins in the air inside the houses to be far higher than those recommended by the World Health Organisation.
"LHA, as landlord to a number of residents on the estate, is responsible for the provision of accommodation which meets basic standards. We anticipate that this test case will be sufficient to demonstrate the extent of the problem and the need for extensive remediation."
LHA said no-one was available to comment until Tuesday.
