Phenol, the cresols, and the dimethylphenols are formed from the atmospheric degradation of benzene, toluene, and the xylenes, respectively, and data are available concerning the atmospheric reactions of these compounds. The potential atmospheric loss processes of phenolic compounds are reaction with N03, OH radicals, and 03, together with wet and dry deposition (these compounds are readily incorporated into rain- and cloud-water and fog). The OH radical reactions proceed by OH radical addition to the aromatic ring and by H-atom abstraction from the substituent -OH and -CH3 groups (Atkinson, 1989) ... 

Large amounts of smoke from oil slick burning can result in oil rain. The formation and possible sinking of extremely viscous and dense residues can damage the sea bed and its inhabitants. The viscous residue may also be transported to shorelines and beaches by ocean tides or currents. Airborne irritants and possibility of secondary fire are sources of concern when combustion has to be carried out close to residential areas. Carbon monoxide, sulfur dioxide, and polycyclic aromatic hydrocarbons (PAH) are common toxic compounds emitted while burning oil on water.
