  ABSTRACT: For full understanding of the bacterial community in the intertidal zones of Bohai Bay, China, we used pyrosequencing-based approach to analyze the 16S rRNA gene of bacteria in the sediments from the two typically intertidal zones - Qikou (Qi) and Gaoshaling (Ga). Results showed that, at a 0.03 distance, the sequences from the Qi sediment were assigned to 3252 operational taxonomic units (OTUs) which belong to 34 phyla, 69 classes and 119 genera, while the 3740 OTUs from the Ga sediment were affiliated with 33 phyla, 66 classes and 146 genera. Comparing the bacterial communities inhabiting in the two intertidal sediments, we observed significant difference in the dominant composition and distribution at phylum, class and genus levels. Canonical correspondence analysis (CCA) showed that the median grain size and DO were the most important factors regulating the bacterial abundance and diversity, while the other environmental factors have effects with different degree.

  ABSTRACT: Between 1972 and 2009, evidence of red tide outbreaks in the Yangtze River Estuary and adjacent waters was collected. A geographic information system (GIS) was used to analyze the temporal and spatial distribution of these red tides, and it was subsequently used to map the distribution of these events. The results show that the following findings. (1) There were three red tide-prone areas: outside the Yangtze River Estuary and the eastern coast of Sheshan, the Huaniaoshan-Shengshan-Gouqi waters, and the Zhoushan areas and eastern coast of Zhujiajian. In these areas, red tides occurred 174 total times, 25 of which were larger than 1000 km(2) in areal extent. After 2000, the frequency of red tide outbreaks increased significantly. (2) During the months of May and June, the red tide occurrence in these areas was 51% and 20%, respectively. (3) Outbreaks of the dominant red tide plankton species Prorocentrum dong-haiense, Skeletonema costatum, Prorocentrum dantatum, and Noctiluca scientillan occurred 38, 35, 15, and 10 times, respectively, during the study interval.

• Article: Sources of fluorescent dissolved organic matter in high salinity seawater (Bohai Bay, China).

  [show abstract] [hide abstract]
  ABSTRACT: Fluorescent dissolved organic matter (FDOM) identified in coastal waters within a large salinity range had been widely reported in previous studies, which stated that conservative mixing of terrestrially derived and river-transported FDOM by clear seawaters could account for the relatively low FDOM fluorescence signals in high salinity seawaters. This study aimed at testing the conservative mixing model in high salinity seawaters in a shallow bay (Bohai Bay, China) with low river flow in a dry season. The water showed high salinities varying in a narrow range (30.52 - 2.07), and salinity effects on fluorescence quantum yields therefore less likely introduced complications to fluorescence data analyses. By applying a parallel factor analysis to fluorescence excitation emission matrices of the water samples, we identified a tyrosine-like FDOM component, a tryptophan-like FDOM component, and two humic substances-like FDOM components. Based on a theoretical analysis, we found that dissolved organic carbon concentrations and suspended solid concentrations of the bulk-water samples as well as the maximum fluorescence signals of each identified FDOM component showed spatial distributions that could not be accounted for by the conservative mixing model. Marine autochthonous processes including microbial activities and FDOM releasing from resuspended sediment were likely to be invoked.

• Article: Correlation between molecular absorption spectral slope ratios and fluorescence humification indices in characterizing CDOM

  [show abstract] [hide abstract]
  ABSTRACT: Ultraviolet–visible absorption spectral slope ratios SR (slope in 275–295nm divided by slope in 350–400nm) and humification index (HIX, integrated fluorescence emission in 435–480nm divided by that in 435–480 and 300–345nm) were compared when characterizing chromophoric dissolved organic matter (CDOM) in three humic acids and 44 whole water samples. HIX increased with increasing pH for humic acids, while their SR showed much more complicated dependencies on pH. There was a negative correlation between SR and HIX. SR increased in the order terrestrial coal/peat<terrestrial soil/river<seawater, while HIX increased in the order seawater<terrestrial soil/river<terrestrial coal/peat. The comparative study in this work indicates that terrestrially derived CDOM has higher HIX and lower SR than marine CDOM. Investigators may potentially use these two indices to compare qualitatively the character of CDOM in different sources (e.g., terrestrial vs. marine).

• Article: Mercury (Hg2+) effect on enzyme activities and hepatopancreas histostructures of juvenile Chinese mitten crab Eriocheir sinensis

  [show abstract] [hide abstract]
  ABSTRACT: We studied the effects of mercury (Hg2+) on antioxidant and digestive enzyme activities in terms of LC50 value and on hepatopancreas histostructures of juvenile Chinese mitten crabs Eriocheir sinensis in 40-day exposure to various concentrations of Hg2+ (0, 0.01, 0.05, 0.10, 0.20, and 0.30 mg/L). The results show that the activities of superoxide dismutase (SOD), glutathione peroxidase (GPX) and catalase (CAT) significantly increased in the concentrations of 0.01 and 0.05 mg/L, while that of enzyme decreased in 0.10, 0.20 and 0.30 mg/L treatments. Meanwhile, Hg2+ disrupted the histostructures of the hepatopancreas, causing decreases in activities of pepsin, tryptase, amylase, and cellulose, which are synthesized in the hepatopancreas. Moreover, as the Hg2+ concentration increased, the survival rate of the crabs decreased, worst at 56.57% in 0.30 mg/L. Therefore, although crabs are able to tolerate low levels of mercury pollution, high levels lead to cellular injury and tissue damage in hepatopancreas, which then loses some of its vital physiological functions such as absorption, storage, and secretion.

• Article: Sedimentary record of polycyclic aromatic hydrocarbons in a reservoir in Northeast China.

  [show abstract] [hide abstract]
  ABSTRACT: A sediment core from the Dahuofang Reservoir in Northeast China was (210)Pb and (137)Cs dated and analyzed for polycyclic aromatic hydrocarbons (PAHs) to track the regional PAH pollution in the past 50 years. The 2-4 ring PAHs peaked in the early 1990s, reflecting the historical role of coal usage in the energy structure in this area. More recently, vehicle emissions caused the continuous increase of the 5+6 ring PAHs. However, the sixteen US EPA priority PAHs showed a significant decline since the early 1990s. This PAH temporal trend is different from the U.S., the European countries and Japan, and is also different from the other areas of China, which could be attributed to the switch from coal to oil or natural gas as the main energy, and the large-scale elimination of outdated combustion facilities and techniques in Northeast China.

  [show abstract] [hide abstract]
  ABSTRACT: Polycyclic aromatic hydrocarbons (PAHs) in 24 surface sediments from the Dahuofang Reservoir (DHF), the largest man-made lake in Northeast China, were measured. The results showed that the concentrations of 16 US EPA priority PAHs in the sediments ranged from 323 to 912 ng/g dry weight with a mean concentration of 592 ± 139 ng/g. The PAH source contributions were estimated based on positive matrix factorization model. The coal combustion contributed to 31 % of the measured PAHs, followed by residential emissions (22 %), biomass burning (21 %), and traffic-related emissions (10 %). Pyrogenic sources contributed ∼84 % of anthropogenic PAHs to the sediments, indicating that energy consumption release was a predominant contribution of PAH pollution in DHF. Compared with the results from the urban atmospheric PAHs in the region, there was a low contribution from traffic-related emissions in the sediments possibly due to the low mobility of the traffic-related derived 5+6-ring PAHs and their rapid deposition close to the urban area.

• Article: Characterizing natural dissolved organic matter in a freshly submerged catchment (Three Gorges Dam, China) using UV absorption, fluorescence spectroscopy and PARAFAC.

  [show abstract] [hide abstract]
  ABSTRACT: This study applied parallel factor analysis (PARAFAC) to fluorescence excitation-emission matrices (EEMs) of natural water samples in a freshly submerged catchment in the upper reach of Three Gorges Dam (China). Two fluorescent natural dissolved organic matter (NDOM) components (humic/fulvic-like) were uncovered and were positively correlated with selected water quality parameters, i.e. dissolved oxygen concentration, dissolved organic carbon concentration, dissolved Kjeldahl nitrogen concentration and total (dissolved plus particulate) phosphorus concentration, respectively. To other water quality parameters (i.e. total nitrogen, particulate nitrogen, particulate phosphorus, dissolved phosphorus, dissolved nitrate, pH, and chemical oxygen demand), either the two components did not show any correlation or only one component showed correlation. In particular, particulate N correlated significantly to the fulvic acid, but not to the humic acid. Meanwhile, two conventional spectroscopic indices i.e. specific UV absorbance at 254 nm (SUVA254) and fluorescence index (FI) indicated that the whole NDOM in the waters were low in aromaticity and predominantly derived from aquatic microbial processes. Given together, it concludes that N and P did not function equally in the NDOM production, and the two components were not derived from the same microbial processes. The EEMs-PARAFAC has proven to be of potential as an effective tool in investigation of the interlink between NDOM and nutrients which may be utilized as an indicator of water environment.

• Article: The correlation of sorption coefficients with nonlinearity of sorption isotherms in contaminated nearshore sediments in Bohai Bay (China).

  [show abstract] [hide abstract]
  ABSTRACT: Phenanthrene sorption to seven nearshore sediments (Bohai Bay, China) collected under similar environments were investigated. Based upon well-fitted Freundlich models, the calculated organic carbon-normalized sorption coefficients at aqueous concentrations of 1 and 5,900 μg/L (PHE supercooled liquid solubility) showed positive and negative correlation with the nonlinearity of sorption isotherms, respectively, and the latter has not previously been reported. The present observations highlighted the viewpoint that PHE at low concentrations is primarily adsorbed to low quantity but highly adsorptive black carbon (BC) whereas partitioning to soft carbon may take over for high concentrations. Therefore, BC should be taken into account when modelling PHE (and analogues) sorption in contaminated sediments, and the correlation approach provides a promising diagnostic tool to this end.

  [show abstract] [hide abstract]
  ABSTRACT: The characteristics of ammonia in drinking water sources in China were evaluated during 2005-2009. The spatial distribution and seasonal changes of ammonia in different types of drinking water sources of 22 provinces, 5 autonomous regions and 4 municipalities were investigated. The levels of ammonia in drinking water sources follow the order of river > lake/reservoir > groundwater. The levels of ammonia concentration in river sources gradually decreased from 2005 to 2008, while no obvious change was observed in the lakes/reservoirs and groundwater drinking water sources. The proportion of the type of drinking water sources is different in different regions. In river drinking water sources, the ammonia level was varied in different regions and changed seasonally. The highest value and wide range of annual ammonia was found in South East region, while the lowest value was found in Southwest region. In lake/reservoir drinking water sources, the ammonia levels were not varied obviously in different regions. In underground drinking water sources, the ammonia levels were varied obviously in different regions due to the geological permeability and the natural features of regions. In the drinking water sources with higher ammonia levels, there are enterprises and wastewater drainages in the protected areas of the drinking water sources.

  ABSTRACT: In recent years, the rapid economic development along Bohai Bay, has brought out continuous increasing of the pollution loads in the Bohai Sea, especially by the large coastal reclamation project, Tianjin Binhai New Area. In the period of 2007-2009, we collected the sediments of the main rivers, estuaries, intertidal zone, and near-shore area of Bohai Bay, and Macrobenthos associated with the marine sediments to assess the influence of hydrodynamics in the coastal environment on the pattern of trace contaminants and the macrobenthic community. Based on data derived from these samples, the levels of polycyclic aromatic hydrocarbons (PAHs), organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs) in sediments followed the order PAHs>OCPs>PCBs>PBDEs. The higher concentrations of PCBs, OCPs, PAHs and PBDEs were found in the estuarine and near-shore environment of the Dagu Drainage River. The spatial distribution of OCPs was different to that of PCBs due to the direction of the velocity field of Bohai Bay in its old and new topography, and the higher water-solubility of OCPs than that of PCBs. The results of the Pearson correlation and the PCA indicate that the medium diameter (MD) of sediments was the predominant factor influencing the distribution of PCBs and OCPs, most sampling sites were characterized mainly by TOC of sediments and biomass of macrobenthos. The results indicate that the distribution of trace contaminants and macrobenthic community in Bohai Bay are mainly affected by the hydrodynamic conditions.

  ABSTRACT: Induction of cytochrome P4501A (CYP1A) has been used as a biomarker in fish for monitoring aromatic and organic contaminants. In this study, a partial of CYP1A gene in redeye mullet (Liza haematocheila) was isolated and sequenced, and then a real-time quantitative reverse-transcription polymerase chain reaction assay was developed for quantification of CYP1A mRNA normalized to β-actin. The developed method was applied to detect CYP1A mRNA expression in redeye mullets collected from Nandaihe (reference site) and Dashentang (impacted site) in Bohai Bay, China. CYP1A mRNA expression values were significantly elevated in redeye mullets from Dashentang compared to a reference site--Nandaihe, which was correlated with the contents of different environmentally relevant pollutants in tissues, particularly with PCBs and PBDEs.

  ABSTRACT: LA50, the Lethal Accumulation of Cu on the Medaka fish (Oryzias latipes) gills that results in 50% mortality during a toxicological exposure (96 hours) in synthetic water was assessed by use of the biotic ligand model (BLM). The LA50 was employed to predict the 96 h Cu toxicity (LC50) to this fish in different natural surface waters in China. The LC50 values were predicted with errors of no more than 1.55 for the river water except for two water samples, one of which was from a tidal river and the other of which was from a river that was subject to joint metal pollution and possibly affected by other pollutants.

  [show abstract] [hide abstract]
  ABSTRACT: Recent occurrence, distribution and mass inventories of 16 priority polycyclic aromatic hydrocarbons (PAHs) proposed by USEPA in the south Bohai Sea (BS) were studied based on the analytical data of 71 surface sediment samples. The concentrations of 16 PAHs varied from 37 to 537 ngg⁻¹ (dry weight). A clear difference was observed between the coastal Bohai Bay (CBB) and its adjacent BS (ABS) in the distribution and compositions of PAHs. The petrogenic source of phenanthrene in CBB was attributable to the industrial wastewater, fugitive fuel leakages from ships and offshore oil production. Four to six ring PAHs were predominantly from the coal and wood combustions in the whole area. The estimated PAH input to the south BS (43,000 km², 56% of BS in area) was 36.6 ton yr⁻¹, indicating that the study area was one of the important reservoirs of PAHs in world.

• Article: Comparison of PARAFAC and PARALIND in modeling three‐way fluorescence data array with special linear dependences in three modes: a case study in 2‐naphthol

  Hao Chen, Binghui Zheng, Yonghui Song
  [show abstract] [hide abstract]
  ABSTRACT: Owing to excited-state proton transfer in 2-naphthol solutions, the fluorescence excitation–emission matrices (EEMs) have factors that are highly dependent in three modes. For the first time such EEMs are used to compare the capability of PARALIND (PARAFAC with linear dependence) and conventional PARAFAC in modeling three-way EEMs having linearly dependent factors in three modes. Two primary conclusions have been drawn. First, the results indicate that a 3-factor PARAFAC model fit the data better than two PARALIND models (type 1 and 2) in this case while equally well with a specially PARALIND model (type 3); second, a negative core consistency (CC) in the 3-factor PARAFAC model is reported but the type 3 PARALIND model reports a nearly 100 CC. This work has demonstrated that a properly constrained PARALIND can fit the very special EEMs of 2-naphthol. The presence of negative CC associated with a perfect PARAFAC model would imply the presence of very special linear dependences in EEMs, which would be used as an “alarm” for the investigators to interpret the data more carefully when dealing with complicated environmental EEMs in the absence of a priori knowledge.

• Article: Grain size effect on PBDE and PCB concentrations in sediments from the intertidal zone of Bohai Bay, China.

  [show abstract] [hide abstract]
  ABSTRACT: Polybrominated diphenyl ethers (PBDEs) are of great environmental concern because their concentrations in the environment are increasing exponentially, and polychlorinated biphenyls (PCBs) are ubiquitous contaminants, although their usage ceased in most industrialized countries in the mid-1970s. This research provides particle-scale understanding of PBDE and PCB distribution in sediments obtained from the three intertidal flats of Bohai Bay, China. The sediments were fractionated into three size groups (<31, 31-63, and >63μm diameter). The PBDE, PCB, and total organic matter contents were not associated with grain size, and the lowest total organic matter was found in the 31-63μm fraction at all three sites. The PCBs and PBDEs were distributed differently among the various fractions from the three sites. The highest level of PCBs and PBDEs occurred in the 31-63μm fraction of the Dagukou sediments, and their lowest levels were found in Lujuhe sediments. In the Qikou sediments, the lowest PCB level occurred in the 31-63μm fraction and the lowest PBDE level was found in the <31μm fraction. These results indicate that the environmental behavior of PBDEs and PCBs are affected by the texture and organic matter content of sediments.

  ABSTRACT: As part of our efforts to identify effective ways and means to keep source water safe, the concept of risk assessment and management is introduced in this paper to address the issue of risk assessment and management of arsenic in source water in China. Carcinogenic and non-carcinogenic risk are calculated for different concentrations of arsenic in source water using the corrective equation between potential health risk and concentration of arsenic in source water with purification process taken into consideration. It is justified through analyses that risk assessment and management is suitable for China to control pollution of source water. The permissible content of arsenic in source water should be set at 0.01 mg/L at present in China, and necessary risk management measures include control contaminated sources and improvement of purification efficiency.

  Article: Phragmites australis and Typha orientalis in removal of pollutant in Taihu Lake, China.

  [show abstract] [hide abstract]
  ABSTRACT: Two plant populations of Phragmites australis and Typha orientalis grown in gravel and sediment substrate were studied to assess their capabilities for purifying polluted water in Taihu Lake, China. The substrate displayed most significant effects on the suspended matter (P < 0.01), with the reduction of 76%-87% and 52%-63% for P. australis, and 83%-86% and 45%-62% for T. orientalis in gravel substrate and sediment substrate, respectively. Both species and substrates significantly decreased the N and P concentrations of water body (P < 0.01). P. australis showed higher total N and P concentrations in tissues than T. orientalis and had a greater potential to remove nutrients from the lake. Phosphate was easily to concentrate in the belowground tissues, while nitrate concentration was higher in leaf and stalk. Therefore, harvesting the aboveground tissues could take most of nitrate out of the sediment. The saturate photosynthetic rate (Asat) of P. australis was higher than that of T. orientalis when grown in sediment substrate. But instance water-use-efficiency (WUEi) (A/E) and intrinsic water use efficiency (A/gs) showed the maximum values of two species grown in river water. With significant difference in gs, however, intercellular CO2 concentration (Ci) had no obvious difference in two species which indicated that high Asat value of P. australis might result from the increased carboxylation capacity of the mesophyll, because of the central role of N in photosynthetic enzymes. Our findings suggest that the plants could absorb most of nitrogen in polluted water, while gravel displayed a high capacity for absorbing the suspended matters and phosphate salts. Therefore, biological and physiological pathways for pollutant removal should be integrated.
