“…Due to toxicity of individual PAHs, different overall effects such as mutagenicity and carcinogenicity would be expected (Li et al, 2014b). In this study, the assessed ecological toxicity of individual PAHs in marine sediments using SQGs values (Table 2), indicated that concentration of all PAHs was below the respective ERL, TEL and TEC values in all stations.…”

“…The plasticizers such as phthalate chemicals [24] and bisphenol A [25] have been proved mutagenic by Ames test and other microbial experiments, which may contribute to the mutagenicity of water near whiteboard factory. As for the increase of MRs of TA98 strain, it could result from the release of organics absorbed in sediments because organics with hydrophobic nature and weak degradation characteristics had accumulate in sediments [26]. After the equilibrium between sorbed and aqueous phases was broken, the absorbed organics could repartition into water and cause secondary pollution to the surroundings [27,28].…”

The judgment and assessment of remediation effect on urban black-odor river still depend on the physical-chemical parameters and lack in ecological safety effects. A set of combined biological toxicity tests were applied to evaluate the ecological effects of one urban black-odor river before and after the remediation. The special growth rate of Chlorella vulgaris and mortality rate of Daphnia magna were used to assess acute toxicity. The Salmonella Typhimurium/Reverse Mutation Assay was applied to test the mutagenicity. The tests by C. vulgaris growth showed that there was no inhibition before and after remediation by overlying water, in contrast promoted the growth of C. vulgaris. The tests by D. magna showed slight toxicity on site 3# before remediation and nontoxic after remediation. The mutagenicity of organic extracts from overlying water at all sampling sites were positive before remediation, but were eliminated after remediation except from 3 of 4 sites on TA98 strain. The addition of the liver microsomal S9 induced the positive mutagenicity on site 4# compared to S9 absence. The results clarified the applicable and the importance of the biological toxicity tests on assessing the remediation effect and potential ecological risk of urban black-odor river.

“…Polycyclic aromatic hydrocarbons (PAHs) are a large set of organic compounds that are inherent in crude oil and its derived products (Inam et al, ). Some of these compounds have the potential to accumulate in living organisms and are probable carcinogens (Li et al, ). Possible mechanism for their carcinogenic nature through DNA‐binding of PAH metabolites has been proposed and illustrated in Figure .…”

Polycyclic aromatic hydrocarbons (PAHs) are among the world's most significant environmental organic contaminants because of their carcinogenic properties.PAHs are widely distributed globally as a result of releases from numerous natural and anthropogenic activities. Consequently, several PAH monitoring studies have been conducted and remediation approaches explored. This article aims to provide the current status of PAH distribution in Nigeria's oil and gas industrial region in relation to the technologies adopted for PAH remediation.Ideally, the findings will provide insight into the challenges in managing organic contaminants derived from petroleum exploration activities in developing countries with Nigeria as a case study.
