“…Similar results reported by Leon et al (2013) and Skarpheoinsdottir et al (2007) demonstrated that bivalves located near ports and cities had relatively high concentrations of LMW PAHs. The presence of LMW PAHs generally indicates a petrogenic origin (Gu et al, 2013;Sun et al, 2016), therefore, in this study, a high abundance of LMW PAHs in this region was typically a characteristic of petrogenic source.…”

“…In our study, low-ring PAHs accounted for a large proportion. Another study in Daya Bay showed that the increase in naphthalene content may be due to oil pollution, and this supports that the contamination of the sediments in Jiaozhou Bay was from crude oil (Sun et al 2016 ).…”

In 2013, the “Qingdao oil pipeline explosion” released an estimated 2000 tons of oil into the environment. Sediment samples were collected from ten sites in Jiaozhou Bay and Shilaoren Beach to evaluate the influence of the spilled oil on the benthic environment 3 years after the oil spill accident. The compositions of oil, bacterial diversity and biotoxicity were examined in this study. The results showed that the concentration of total petroleum hydrocarbons (TPHs) peaked near the oil leak point and gradually decreased along the coastline, ranging from 21.5 to 133.2 μg/g. The distribution of polycyclic aromatic hydrocarbons (PAHs) was correlated with TPH, and naphthalenes were dominant in the 20 detected PAHs. The bacterial diversities in seriously polluted and slightly polluted sediments were completely different. As degrading bacteria, Alcanivorax and Lutibacter were the main genera at the oil-polluted sites. The analysis of biotoxicity by the luminescent bacteria method showed great differences among the polluted sites, the control site in Jiaozhou Bay, and the non-polluted site outside of Jiaozhou Bay. The biotoxicity also peaked at the site near the oil leak point. These results indicate that the oil spill that occurred 3 years ago still affects the environment and impacts the bacterial communities in the sediments.Electronic supplementary materialThe online version of this article (10.1186/s13568-018-0603-6) contains supplementary material, which is available to authorized users.

“…PAHs are primarily derived from incomplete combustion or pyrolysis of organic materials, for instance when coal, oil, gas, wood, garbage or tobacco are burned [23]. PAHs enter the marine environment through several mechanisms including atmospheric deposition, discharge of industrial sewage, marine transport, terrestrial runoff, and petroleum spills [24]. PAHs are distributed among different trophic levels through bioaccumulation processes.…”

“…Aquatic organisms such as shrimp, are capable of concentrate pollutants directly from sediments and water and transfer these pollutants through the food web [25]. In terms of human exposure, PAHs have been reported to be carcinogenic, mutagenic and teratogenic [24]. The most significant endpoint of PAH toxicity after long term exposure is cancer, they can lead to proliferation of mutated cells resulting in cancer growth [26].…”

“…Moreover, the shrimps sampled in estuary regions seem to be the mo contaminated ones [24,36,54,60,106,109,117]. For the PAHs evaluation the number of samples analysed varied between 3 [54,116,117,119,120] and 10 [24], the number of individuals collected ranged between 10 [117] and 300 [24]. The number of specimens pooled per sample ranged between 7 [109] and 200 [120].…”

Shrimps are widely distributed in coastal areas, estuaries and rivers. Although this shellfish is a good source of nutrients, it can also accumulate environmental contaminants, such as organochlorine pesticides (OCPs), brominated flame retardants (BFRs), synthetic musks (SMs) and polycyclic aromatic hydrocarbons (PAHs). Due to their bioaccumulative properties, these pollutants are endocrine disruptors. In this review, an overview of the world's shrimp market, pollutants legislation and values found in shrimp samples will be discussed. Shrimps analysed from all continents showed the presence of contaminants, Asia being the continent with the highest values reported. The concentration values reached a maximum of 26100 ng/g wet weight (ww) for OCPs, of 226.45 ng/g ww for BFRs, of 12.1 ng/g ww for SMs and of 50650 ng/g ww for PAHs. Exposure data and risk, taken from different studies, are very variable and indicate that shrimp's consumption may represent a risk especially in certain geographic areas.
