Iran points out that some of the hydrocarbons, such as polycyclic aromatic hydrocarbons, are very toxic.

The presence of an amine group strongly increases the reactivity of the aromatic ring, due to an electron donating effect.

For example, a number of research institutions across developing countries have discovered the medicinal uses of aromatic and medicinal plants, but are unable to commercialize those findings.

The dry deposition was in the form of gaseous pollutants and soot particles containing heavy metals and polycyclic aromatic hydrocarbons, including benzoapyrene, which is a known carcinogen.

While being toxic to marine life, polycyclic aromatic hydrocarbons (PAHs), the components in crude oil, are very difficult to clean up, and last for years in the sediment and marine environment.

Iran states that its territory was exposed to wet deposition from approximately 350,000 tonnes of soot, as well as nitrogen and sulphur oxides, organic carbons, heavy metals and polycyclic aromatic hydrocarbons from the oil well fires in Kuwait.

Other chemical differences between these two groups include the nature of heteroatoms (O and N enriched in natural products, and S and halogen atoms more often present in synthetic compounds), as well as level of non aromatic unsaturation (higher in natural products).

2 HOCl Cl2O H2O K (0 C) 3.55x10 3 dm3 molDespite this, it has been suggested that dichlorine monoxide may be the active species in the reactions of HOCl with olefins and aromatic compounds, as well as in the chlorination of drinking water.
