Nitro Derivatives of Polycyclic Aromatic Hydrocarbons (NO2-PAH),ases from motor vehicles are regarded as being the main source. Although present in smaller quantities than the corresponding PAH, they deserve special attention because of their biological activity: a number of them have proved to be mutagenic and carcinogenic in animal testing.

Collingwood’s Claim that History is a Scienceuse Collingwood has never worked it out properly. Collingwood’s claim concerning the scientific nature of history is based on his view that it is inferential, though in a specific way, that is, being neither inductive nor deductive.
