“…The detected range of ΣPAH among the 12 sampling sites was 7.79 to 19.1 ng/L (mean 13.4 ng/L). This finding is similar to that of previous studies; 13 PAHs, 6.83 to 13.81 ng/L (mean 9.4 ng/L) in the Japan Sea [ 49 ]; 13 PAHs, 10.9 to 29.7 ng/L (mean 19.6 ng/L) in the Sea of Japan and East Sea [ 50 ]. Phe was the predominant species (median: 5.67 ng/L).…”

Polycyclic aromatic hydrocarbon (PAH) concentrations in wharf roach (Ligia spp.), as an environmental indicator, and in environmental components of the intertidal and supralittoral zones were determined, and the PAH exposure pathways in wharf roach were estimated. Wharf roaches, mussels, and environmental media (water, soil and sand, and drifting seaweed) were collected from 12 sites in Japan along coastal areas of the Sea of Japan. PAH concentrations in wharf roaches were higher than those in mussels (median total of 15 PAHs: 48.5 and 39.9 ng/g-dry weight (dw), respectively) except for samples from Ishikawa (wharf roach: 47.9 ng/g-dw; mussel: 132 ng/g-dw). The highest total PAH concentration in wharf roach was from Akita (96.0 ng/g-dw), followed by a sample from Niigata (85.2 ng/g-dw). Diagnostic ratio analysis showed that nearly all PAHs in soil and sand were of petrogenic origin. Based on a correlation analysis of PAH concentrations between wharf roach and the environmental components, wharf roach exposure to three- and four-ring PAHs was likely from food (drifting seaweed) and from soil and sand, whereas exposure to four- and five-ring PAHs was from several environmental components. These findings suggest that the wharf roach can be used to monitor PAH pollution in the supralittoral zone and in the intertidal zone.

“…No statistically significant differences were found between the dissolved and particulate PAH contents in the estuarine waters of both rivers. This is consistent with results previously obtained in rivers and estuaries of the northwestern Sea of Japan [ 15 ] and contrary to the data from PAH studies in the coastal environment of the Sea of Japan, demonstrating that the DPAH fraction is larger than the PPAH fraction [ 16 , 24 , 25 ]. This finding indicates that the estuaries under study are effective geochemical barriers where a significant amount of PPAHs are deposited.…”

The noticeable rise in TPAHs concentrations observed during the cold period resulted from significant PAH emissions from residential and municipal heating systems.…”

“…A single PAH survey in a few rivers and estuaries adjacent to the Sea of Japan (the Russian region) found low levels of contamination in the summer [ 15 ]. However, given that studies in the Russian coastal waters of the Sea of Japan have shown a significant increase in PAH concentrations during the cold season due to emission from heating systems [ 16 ], this assessment may not be correct.…”

The seasonal polycyclic aromatic hydrocarbon (PAH) variability was studied in the estuaries of the Partizanskaya River and the Tumen River, the largest transboundary river of the Sea of Japan. The PAH levels were generally low over the year; however, the PAH concentrations increased according to one of two seasonal trends, which were either an increase in PAHs during the cold period, influenced by heating, or a PAH enrichment during the wet period due to higher run-off inputs. The major PAH source was the combustion of fossil fuels and biomass, but a minor input of petrogenic PAHs in some seasons was observed. Higher PAH concentrations were observed in fresh and brackish water compared to the saline waters in the Tumen River estuary, while the PAH concentrations in both types of water were similar in the Partizanskaya River estuary, suggesting different pathways of PAH input into the estuaries. The annual riverine PAH mass flux amounted to 0.028 t/year and 2.5 t/year for the Partizanskaya River and the Tumen River, respectively. The riverine PAH contribution to the coastal water of the Sea of Japan depends on the river discharge rather than the PAH level in the river water.

Substrate availability and toxicity shape the structure of microbial communities engaged in metabolic division of labor

Metabolic division of labor (MDOL) represents a widespread natural phenomenon, whereby a complex metabolic pathway is shared between different strains within a community in a mutually beneficial manner. However, little is known about how the composition of such a microbial community is regulated. We hypothesized that when degradation of an organic compound is carried out via MDOL, the concentration and toxicity of the substrate modulate the benefit allocation between the two microbial populations, thus affecting the structure of this community. We tested this hypothesis by combining modeling with experiments using a synthetic consortium. Our modeling analysis suggests that the proportion of the population executing the first metabolic step can be simply estimated by Monod‐like formulas governed by substrate concentration and toxicity. Our model and the proposed formula were able to quantitatively predict the structure of our synthetic consortium. Further analysis demonstrates that our rule is also applicable in estimating community structures in spatially structured environments. Together, our work clearly demonstrates that the structure of MDOL communities can be quantitatively predicted using available information on environmental factors, thus providing novel insights into how to manage artificial microbial systems for the wide application of the bioindustry.
