1. During the Gulf War, a few years back, tens of thousands of seabirds were killed due
to oil spills. Do you know what makes crude oil on ocean water so deadly?
2. Crude oil is not used in the same state it is produced at the offshore wells. Before it
is refined the oil contains potentially fatal components.
3. Crude oil is made up of compounds of carbon and hydrogen called hydrocarbons.
These hydrocarbons may be paraffin, the oil which is used as a fuel in heaters and
lamps or cycloparaffins (naphthenes) or aromatic compounds in varying proportions.
While crudes found in the U.S. are mostly paraffinic, those found along the Gulf
Coast are naphthenic which contains sulphur compounds in varying amounts, a small
amount of nitrogen and very little oxygen. All crudes will have nickel and vanadium
in high concentration. Iron may be found in inorganic form due to corrosion of pipes.
4. Paraffins like methane and ethane are asphyxiants which will cause suffocation. The
effects of cycloparaffins are more or less similar to those of the paraffins but the
unsaturated paraffins are more noxious than the saturated ones. The sulphur
compounds present in crude oil can be toxic. Sulphur in the form of aromatic
thiophenes, benzoethophenes can damage the livers and kidneys of sea animals.
Sulphur compounds like mercaptes can be very dangerous.​
