Both the Massachusetts Department of Environmental Protection (MADEP) and the Total Petroleum Hydrocarbon Criteria Working Group (TPHCWG) developed fraction-based approaches for assessing human health risks posed by total petroleum hydrocarbon (TPH) mixtures in the environment. Both organizations defined TPH fractions based on their expected environmental fate and by analytical chemical methods...

Petroleum hydrocarbon residues in weathered soils may pose risks to humans through the ingestion pathway. To understand the factors controlling their gastrointestinal (GI) absorption, a newly developed experimental extraction protocol was used to model the GI solubility of total petroleum hydrocarbon (TPH) residues in highly weathered soils from different sites. The GI solubility of TPH residue...

Several industrial activities around the Niger Delta region have contributed to widespread contamination of marine ecosystems with organochlorine compounds (OCs), petroleum products that are a source polycyclic aromatic hydrocarbons (PAHs). These pollutants tend be persistent in environment and also often highly toxic biota. The study was therefore, aimed at determining concentrations organic (...

Drilling operations of petroleum generate oily wastes. The disposal of a significant amount of oil-based drill muds has caused soil contamination and critical environmental impacts in the last decades.The current study aimed to investigate the potential of microbial remediation for an aged oil-based drilling waste and to monitor the fluctuation in microbial population throughout a ...

The present study discusses an assessment of oil, grease, total petroleum hydrocarbons (TPH) and some heavy metals in surface and ground water within and around the Nigeria National Petroleum Corporation (NNPC) depot, in Apata, Ibadan metropolis in other to assess the pollution status of the water. Samples were collected randomly within and around the depot. Control samples were taken from Awba...

The assessment of the quality of carwash effluents has received scant attention as a potential source of public and environmental health hazard in South Africa as demonstrated by the lack of literature in this subject. The physicochemical quality and potential ramifications of carwash effluents on receiving waterbodies were investigated in this study. Grab effluent samples were collected from s...

This work was aimed at evaluating the relative merits of bioaugmentation, biostimulation and surfactant-enhanced bioavailability of a desert soil contaminated by crude oil through biopile treatment. The results show that the desert soil required bioaugmentation and biostimulation for bioremediation of crude oil. The bioaugmented biopile system led to a total petroleum hydrocarbon (TPH) reductio...

ports’ activities could result in oil spills occurrences and oil pollution in different ways including the discharges of ships’ oily wastes, discharges of oily ballast water and leaks at oil terminals. in this paper, using the results of the analyses of the hydrocarbon compounds in the samples collected from the sediments in the anzali port in the caspian sea in iran, the levels of oil pollutio...

1. introduction isfahan oil refinery (isfahan, iran) is responsible for the production of huge amounts of oil waste. as the released organic compounds are highly toxic, carcinogenic, and mutagenic, they can potentially contaminate the soil and groundwater resources of the adjacent area. this is particularly important in isfahan where arid/semi-arid climate has limited the access to adequate sur...

The contamination of soil due to activities involved in crude oil exploration and production, spillage emanating from pipeline vandalization, sabotage, theft, corrosion the enterprises artisanal refineries pose health ecological problems. This is especially as contains chemical compounds which are grouped into Total Petroleum Hydrocarbons (TPH), known be toxic, mutagenic, carcinogenic. Bioremed...
