A dietary feeding study with polycyclic aromatic hydrocarbons (PAHs) was conducted with juvenile Chinook salmon (Oncorhynchus tshawytscha) to mimic exposure from urban estuaries during their transition from freshwater to seawater. A significant reduction in mean fish dry weight was observed only for the highest doses; however, analysis of variance (ANOVA) using standard deviations and examination of the cumulative frequency plots revealed high variability among all treatments. The skewed fish weight distribution revealed a large number of small fish in several treatments compared with control fish. Analyses of whole-body lipids and several parameters in blood plasma related to growth and metabolism indicated alterations for most treatments. These results and trends in growth, plasma chemistry, and lipids as a consequence of PAH exposure were similar to those in fish exhibiting starvation, which we have termed "toxicant-induced starvation". Based on these results, we conclude that PAHs are toxic to salmonids at this life stage and the reduction in biomass and lipid stores observed here would have the potential to cause increased mortality for individuals during their first winter.

In a market basket study made in Nanjing, China, in which the most common consumed nine kinds of vegetables foodstuffs were sampled, the contents of 16 polycyclic aromatic hydrocarbons (PAHs) were analyzed using gas chromatography with mass spectrometer detector (GC-MS). The results showed that the total amount of 16 PAHs was within the range of 60.5~312 ng g−1 (wet weight). The ranking of total concentrations for different types of vegetables in decreasing order was leafy vegetable, fruit vegetable, and rhizome vegetable. Source analysis suggested that coal, oil, or other incomplete combustion of biomass mainly contributed to the concentration of PAHs. The margin of exposure (MOE) approach with age/gender group-specific daily dietary exposure level was used to estimate the carcinogenic risk. The calculated total mean MOE in the case of BaP and PAH4 (sum of BaA, CHR, BbF, and BaP) was 14960 and 7723, respectively, for local residents. In addition, the MOEs in PAH4 for some groups of both male and female were below the critical limit of 10 000 proposed by EFSA. Therefore, health effect owing to the consumption of vegetables on local residents needs high concern.

Immune System Modulation

Polycyclic aromatic hydrocarbons (PAH) have been demonstrated to affect immune system modulation. The freshwater species of fish, Lepomis macrochirus (bluegill), was employed to investigate the effects of a 14-day dietary exposure to PAH including 2-aminoanthracene (2-AA), 2-methylnaphthalene (2-MN), and 9,10-dimethylanthracene (9,10-DMA) and a mixture of these 3 compounds at a total dose of 3.1 ± 0.01 mg on lymphocyte proliferation stimulated with 3 mitogens (concanavalin A [Con A], phorbol ester, and calcium ionophore). 2-Aminoanthracene was mitogenic itself and with added mitogens. 2-Methylnaphthalene induced some stimulatory and some inhibitory effects upon cell proliferation by Con A. 9,10-DMA and the mixture each suppressed cell proliferation. The mixture was highly suppressive to lymphocytes. Intracellular baseline calcium levels were reduced, possibly as a step prior to cell death. All PAH compounds tested were immunomodulatory to bluegill lymphocytes. Bluegill were demonstrated to have utility as a biomarker species for investigation of immunotoxicity.
