Bioremediation and phytoremediation of total petroleum hydrocarbons (TPH) under various conditions

International Journal of Phytoremediation, 2017
Remediation of contaminated soils is often studied using fine-textured soils rather than low-fertility sandy soils, and few studies focus on recontamination events. This study compared aerobic and anaerobic treatments for remediation of freshly introduced used motor oil on a sandy soil previously phytoremediated and bioacclimated (microorganisms ...

Total petroleum hydrocarbons in edible marine biota from Northern Persian Gulf

Environmental Monitoring and Assessment, 2015
To provide a baseline information for consumer's health, distribution of total petroleum hydrocarbons in 18 edible marine biota species from northern Persian Gulf was evaluated. The samples were purchased from fish market of Hormozgan Province, South of Iran.

Methodologies for Analysis and Identification of Total Petroleum Hydrocarbons

2019
Analysis of total petroleum hydrocarbons (TPHs) from impacted media involves the collection and preservation of samples followed by extraction, concentration, and clean-up of the sample extract as well as detection and quantification of the petroleum hydrocarbons (PHs). Extraction involves the use of methods such as continuous liquid-liquid extraction,

Large scale treatment of total petroleum-hydrocarbon contaminated groundwater using bioaugmentation

Journal of Environmental Management, 2018
Bioaugmentation or the addition of microbes to contaminated sites has been widely used to treat contaminated soil or water; however this approach is often limited to laboratory based studies. In the present study, large scale bioaugmentation has been applied to total petroleum hydrocarbons (TPH)-contaminated groundwater at a petroleum facility. Initial

Fungal proliferation and hydrocarbon removal during biostimulation of oily sludge with high total petroleum hydrocarbon

Environmental Science and Pollution Research, 2019
A laboratory-scale study was conducted to investigate the effect of bioaugmentation (BA) and biostimulation (BS) on the remediation of oily sludge with high total petroleum hydrocarbon (TPH) content (269,000 mg/kg d.w. sludge). TPH concentration significantly decreased by 30.4% (P

Development of Toxicity Criteria for Petroleum Hydrocarbon Fractions in the Petroleum Hydrocarbon Criteria Working Group Approach for Risk-Based Management of Total Petroleum Hydrocarbons in Soil

Drug and Chemical Toxicology, 1999
The Total Petroleum Hydrocarbon Criteria Working Croup (TPHCWG) was formed in 1993 based on the observation that widely different clean-up requirements were being used by states at sites that were contaminated with hydrocarbon materials such as fuels, lubricating oils, and crude oils.

Isolation of potential total petroleum hydrocarbon degraders from river sediments

2010 International Conference on Science and Social Research (CSSR 2010), 2010
The terrestrial environment and its surrounding areas are vulnerable to contamination by hydrocarbon contaminants with more than half of the petroleum released into the waters is estimated to be adsorbed onto the suspended solids and settled as sediments.

Total organic carbon as a screening method for petroleum hydrocarbons

Chemosphere, 1999
Total Organic Carbon (TOC) was used to screen soil samples for petroleum hydrocarbon contamination at a former refinery in Ohio. TOC was measured in the field via wet oxidation using chromic acid and colorimetry. Selected samples were also analyzed for Total Petroleum Hydrocarbons (TPH). Comparison of TOC and TPH results demonstrated that for this site,

Approaches for Remediation of Sites Contaminated with Total Petroleum Hydrocarbons

2019
For more than a decade, the primary focus of environmental experts has been to adopt risk-based management approaches to clean-up the total petroleum hydrocarbons (TPHs)-polluted sites that pose potentially destructive ecological consequences. This attention led to the development of several physico-chemical, thermal, and biological technologies that ...
