“…The total n-alkane concentrations in the fish tissues ranged from 7.27 µg/g Dwt in C. idella (herbivorous) to 23.14 µg/g Dwt in the P. abu (filter feeder). They were similar to the concentration ranges reported in fish tissues and muscles from different rivers and lakes (Colombo et al, 2007;Olaji et al, 2014;Al-Imarah et al, 2016;Wang et al, 2019) The predominance of nC 24 in the fish tissues may be due to the fish feeding on algae and detritus because the major source of nC 24 is likely from the algae, phytoplankton, and bacteria (Gomes and Azevedo, 2003;Shahbazi, 2009). The distribution of n-alkanes and the high level of nC 29 (0.393 µg/g ) in the fish tissue of C. carpio may be attributed to their feeding on a freshwater higher, mainly emergent, plants because usually nC 27 nC 29 and nC 31 are the major n-alkanes in plant waxes of these plants (Eglinton and Hamilton, 1967;Simoneit, 1978;Ficken et al, 2000;Duan and Xu, 2012).…”

Aliphatic hydrocarbon n-alkanes, pristane (Pr), and phytane (Ph) were determined in the tissues of sixeconomic freshwater fish species (Luciobarbus xanthopterus, Ctenophyngodonidella, Cyprinus carpio, Tilapia zillii, Palanizaabu, and Leuciscus vorax) collected from the Shatt Al-Arab river. They were analyzed bycapillary gas chromatography - flame ionization detector (GC-FID). The carbon chain lengths of n-alkanesin the fish tissue samples ranged from nC13 to nC36. The highest concentration of the total n-alkanes wasdetected in the filter feeder P. abu tissue (23.14Î¼g/g dry weight) and the lowest concentration was in theomnivorous C. carpio tissue (3.76 Î¼g/g dry weight). The major sources of the n-alkanes, pristanes, andphytanes were from petroleum hydrocarbons based on the results of the molecular biomarker indices andthe ratios of CPI (carbon preference index), Pr/Ph, LMW/HMW (total nC13-C24/total nC25-nC36), nC17/Pr,and nC18/Ph. The percentage of n-alkanes from petroleum related-products ranged from 83.2% to 94.8%,whereas the natural biogenic sources were in the order of bacterial (3.7-11.7%) > higher plant wax (0.0-9.1%) > algal (0.1-1.2%) sources. The occasion of high fractions of n-alkanes and isoprenoids from petroleumhydrocarbons in these fish tissues indicated that the foster habitats were highly contaminated by crude oil.Further studies are required to investigate the bioaccumulation of other anthropogenic contaminants suchas plasticizers, pesticides, and polycyclic aromatic hydrocarbons fresh-water organisms.

“…The mean BSAFs for the total of the eight MLPs in mollusks and crustaceans were 15.5 and 2.03, respectively. There are no MLP BSAFs available for comparison, but studies of other organic pollutants have revealed that the differences in the BSAF are a consequence of bioavailability, uptake-elimination, and biotransformation. , …”

“…The octanol–water partition coefficient ( K ow ) is an important factor affecting the bioaccumulation and biomagnification potential of nonionized organic compounds, while the octanol–water distribution coefficient ( D ow ) is an alternative for studying ionized analytes. , Our studied MLPs are soluble in lipids and are suggested to have high log K ow values. In addition, a previous study predicted the log K ow values for acidic MLPs, including AZA1 (4.06 ± 2.20), AZA2 (4.32 ± 2.33), OA (4.45 ± 2.60), DTX1 (4.79 ± 2.67), and DTX2 (4.46 ± 2.55) .…”

Only individual samples with levels higher than the LOQs were further subjected to regression analysis.…”

Marine lipophilic phycotoxins (MLPs) are produced by toxigenic microalgae and cause foodborne illnesses. However, there is little information on the trophic transfer potential of MLPs in marine food webs. In this study, various food web components including 17 species of mollusks, crustaceans, and fishes were collected for an analysis of 17 representative MLPs, including azaspiracids (AZAs), brevetoxins (BTXs), gymnodimine (GYM), spirolides (SPXs), okadaic acid (OA), dinophysistoxins (DTXs), pectenotoxins (PTXs), yessotoxins (YTXs), and ciguatoxins (CTXs). Among the 17 target MLPs, 12, namely, AZAs1–3, BTX3, GYM, SPX1, OA, DTXs1–2, PTX2, YTX, and the YTX derivative homoYTX, were detected, and the total MLP concentrations ranged from 0.316 to 20.3 ng g–1 wet weight (ww). The mean total MLP concentrations generally decreased as follows: mollusks (8.54 ng g–1, ww) > crustaceans (1.38 ng g–1, ww) > fishes (0.914 ng g–1, ww). OA, DTXs, and YTXs were the predominant MLPs accumulated in the studied biota. Trophic dilution of the total MLPs was observed with a trophic magnification factor of 0.109. The studied MLPs might not pose health risks to residents who consume contaminated seafood; however, their potential risks to the ecosystem can be a cause for concern.

“…Bioaccumulation occurs from sediment to biota when BSAF are close to, or greater than 1 (Yang et al, 2019). The BSAF values of aliphatic hydrocarbons dramatically varied from 0.829 in Cyprinus carpio to 17.3 in Silurus asotus (Wang et al, 2019), due to the differences in selective excretion abilities and elimination mechanisms among different species (Wang et al, 2018).…”

In order to evaluate the pollution level and risk of total petroleum hydrocarbon (TPH), seawater, sediments, and organisms were sampled from the southern sea area of Zhejiang province (Yangtze River Delta, China) between 2017 and 2019. Petroleum hydrocarbons were widely present in the aquatic environment as well as in products, and their concentrations were highly variable. The average value of PI exceeded 1 from 2017 to 2018, 45.46% to 69.19% samples for seawater and 56.87% to 50.00% samples for sediment were polluted. The results showed significant differences in the TPH concentration in various aquatic organism species. The average TPH value in aquatic organisms order was bivalve＞shrimp＞crab＞fish, further reflecting the ability to accumulate and metabolize TPH exists differently among aquatic organisms within the same culturing pond environment. It is relatively safe to eat aquatic products based on the exposure risk index far below threshold values in this study. Therefore, it will be prudent to undertake regular monitoring of TPH to ensure effective ecosystem functioning as well as seafood safety in Zhejiang southern ocean.
