Particulate Matter

Small But Deadly: The Spectre Called SPM

Suspended Particulate Matter (SPM) has its genesis in dust, fumes, mist, smoke and in its deadlier cousin: smog. A major chemical component of SPM is lead. Other particularly harmful constituents include nickel, arsenic and sulphur. SPM has a major impact on lung and lung tissue, nose tissue and tear ducts; in fact, scientists believe that prolonged exposure to polluted air is more harmful than passive smoking.
