Total arsenic (As) in suspended particulate matter (SPM) of lacustrine ecosystems has been extensively documented, but knowledge on the distribution of As between the particle and aqueous phases in freshwater lakes remains largely unknown. The present study employed a rapid method to determine the total and dissolved As and As in SPM at sites covering the entire areas of three large shallow lakes in China, e.g., Taihu, Chaohu, and Dianchi, to obtain a Brepresentativem ean value of the As concentration in various phases. The average concentrations of total and dissolved As were below 6.0 and 3.3 μg/L, respectively. Arsenic in SPM was much higher than that in waters, as ranging from 24.7 to 516 μg/g. Lake Taihu exhibited extensive seasonal variation both in total and dissolved As, while little difference was observed in SPM concentration, with an average value of 54.2 and 49.3 mg/L in winter and summer, respectively. Among the algae in the three lakes, Cyanophyta dominated in both cell abundance and biomass. Algae mass occupied significant parts of SPM, especially in Dianchi; the proportions of algae in the SPM fractions were measured as 10.4 and 7.1 % in Taihu in winter and summer, 4.5 % in Chaohu, and 53.3 % in Dianchi, both in summer season. The total As in SPM had a significant positive relationship with total As in water and a high distribution coefficient (Kd) between SPM and dissolved fraction of As at all three lakes. The high proportions of Algae, especially Cyanophyta in the composition of SPM in the three large shallow lakes, might play an important role in affecting the As distribution between the aqueous and particulate phases in aquatic ecosystem.

“…MCs are very stable compounds (Jones and Orr, 1994;Harada, 1996), and are known to accumulate in sediment (Kankaanpää et al, 2009) and various aquatic organisms (Amorim and Vasconcelos, 1999;Ferrão-Filho et al, 2002;Magalhães et al, 2003;Xie et al, 2007;Lance et al, 2010;Zhang et al, 2012), and can be transferred to the organisms located at the upper trophic levels through the food chain (Ibelings et al, 2005;Xie et al, 2005;Smith and Haney, 2006).…”

“…In the natural environment, MCs accumulate in a wide range of aquatic animals, including fish (Magalhães et al, 2003;Mohamed et al, 2003), shrimps (Chen and Xie, 2005b), gastropods (Chen and Xie, 2005b;Zhang et al, 2012;Zurawell et al, 1999) and bivalves (Chen and Xie, 2005a;Williams et al, 1997). MCs are found in both the viscera and also in the edible muscle/foot.…”

Microcystins (MCs) are the toxic products of harmful algal blooms and they accumulate in fish. The accumulation of MCs in fish living in different trophic levels from different parts of Lake Taihu was determined. This information was then used to evaluate the risks posed by the MCs in fish to human health. The concentrations of three MCs, MC-LR, MC-YR and MC-RR, were quantified in the following four fish species: silver carp (Hypophthalmichthys molitrix), bighead carp (Aristichthys nobilis), crucian carp (Carassius auratus) and common carp (Cyprinus carpio), using high performance liquid chromatography interfaced with tandem (triple quadrupole) mass spectrometry. The mean concentrations of MCs in the muscle, the kidney, the intestinal wall and the heart were significantly different among the four fishes except in the liver. C. carpio contained the highest mean concentration of MCs in the muscle (31.7 ± 12.1 ng/g, dry mass (dm)), whereas C. auratus had the highest mean concentrations of MCs in the liver (45.4 ± 44.5 ng/g, dm), kidney (114 ± 51.1 ng/g, dm), intestinal wall (2.04 × 10 3 ± 4.43 × 10 3 ng/g, dm) and heart (59.5 ± 26.7 ng/g, dm). The mean concentration of MCs in the intestinal walls of the fish species was significantly higher than in other organs (p b 0.01). The fish from Meiliang Bay had significantly higher concentrations of MCs than those from the centre, west or south banks of the lake (p b 0.01). The body lengths and masses of the fish were negatively correlated with the concentrations of MCs in the kidney (p b 0.05) and heart (p b 0.01). The average daily intake (ADI) of MCs in the muscle of all fishes exceeded the provisional tolerable daily intake (TDI) set by World Health Organization. The estimated daily intakes of MCs in 55.6% of the muscle samples exceeded the TDI. The MCs in the tissues of the fish from Lake Taihu pose potential risks to the health of humans who consume these four fish species.
