PRINCIPAL COMPONENT ANALYSES OF PAH DATA FROM SUNDSVALL

Abstract

Concentrations of fluoride and polycyclic aromatic hydrocarbons (PAH) have been determined in ambient air in Sundsvall, Sweden. Principal component analysis has been used to find statistically independent linear combustion of th PAH's. The results show that some of the PAH's are associated with the major sources in the area, such as the aluminium industry and traffic.
