Source and Control of Hydrocarbon Pollution | IntechOpen

2019-01-26· Hydrocarbon contamination in water avoids the penetration of light into the water and the exchange of gases for consumption by aquatic plants. This leads to the death of the plant because plant becomes incapable to photosynthesize and hence can affect the food chain. Plants consume the pollutants from the contaminated water which can be passed to humans and animals through the food .

Extractable Petroleum Hydrocarbons (EPH) in Water by GC/FID

Hydrocarbons (EPH) in water, divided into two boiling point ranges, each quantitated against eicosane (nC20). EPH w10-19 measures hydrocarbons that elute between nC10 and nC19 (b.pt. range of ~ 174-330˚C). EPH w19-32 measures hydrocarbons that elute between nC19 and nC32 (b.pt range of ~ 330-467˚C). The EPH parameters are precursors to the calculation of Light and Heavy Extractable .
