The water quality assessment of part of oil producing Niger Delta of Nigeria is in progress.What parameters in water and sediment samples are associated with oil exploitation.
our lab determines low-level PAH for NOAA and USFWS using performance based methods. we also conduct environmental baseline surveys for the offshore oil industry that involve a standard set of analytes in water and soil. contact [email protected]
Jones Environmental Laboratory is based in the UK but does analysis for a number of companies in Africa. Also, UIS Organic, based in Johannesburg, South Africa.
You'll need to look for components such as BTEXN and specifically high chain carbon compiunds C10 - C40 for crude. Also, PAH compounds.
You should request analysis of individual PAH compounds, probably including alkanes. This will allow fingerprinting of PAHs for comparison with any future discharges of petroleum to the water.
