Quantitative assessment data of PAHs and N-PAHs in core sediments from the Niger Delta, Nigeria.

Abstract Polycyclic aromatic compounds (PACs) pollution has been the focus of environmental research, mostly due to their mutagenicity, carcinogenicity, teratogenicity and genotoxicity. Concentrations of polycyclic aromatic hydrocarbons (PAHs) and the nitrogen-containing analogues (N-PAHs) (which tend to accumulate in sediments rather than water) was measured in 2 cm intervals segments from Bonny Estuary, Niger Delta using GC-MS. Data showed that PAHs/N-PAHs levels ranged from 8699–22528µg/kg and 503–2020µg/kg, respectively. Furthermore, the data revealed that ƩPAHs level in the estuarine segments was > 45% higher than DPR/EGASPIN intervention limit. This gives insight on PAHs/N-PAHs contamination in the oil rich region.
