First identification of the hepatotoxic microcystins in the serum of a chronically exposed human population together with indication of hepatocellular damage.
TLDR
The data raise the question whether extended exposure in the range of the TDI or up to a factor of 10 above it may already lead to indication of liver damage, and demonstrate a risk of health effects from chronic exposure to MCs at least for populations with high levels of exposure, like fishermen at Lake Chaohu.
Organ distribution and bioaccumulation of microcystins in freshwater fish at different trophic levels from the eutrophic Lake Chaohu, China
TLDR
The organ distribution and bioaccumulation of hepatotoxic microcystins (MCs) in freshwater fishes at different trophic levels from the large, shallow, eutrophic Lake Chaohu in September 2003 are reported, indicating that fish are already severely contaminated by MCs and that the local authorities should warn the public of the risk of poisoning by eating the contaminated fish.
Tissue distributions and seasonal dynamics of the hepatotoxic microcystins-LR and -RR in two freshwater shrimps, Palaemon modestus and Macrobrachium nipponensis, from a large shallow, eutrophic lake

TLDR
Among the shrimp muscle samples analyzed, 31% were above the provisional WHO TDI level, suggesting the risk of consuming shrimps in Lake Chaohu, and gonads of these invertebrates are the second important target organ of MCs.
Methane and carbon dioxide fluxes from a shallow hypereutrophic subtropical Lake in China
Up to now, there have been few studies in the annual fluxes of greenhouse gases in lakes of subtropical regions. The fluxes of methane (CH4) and carbon dioxide (CO2) across air-water interface were
Transfer, distribution and bioaccumulation of microcystins in the aquatic food web in Lake Taihu, China, with potential risks to human health.
TLDR
The main uptake of MC-YR in fish seems to be through the gills from the dissolved MCs, which is the first study reporting MCs accumulation in the gonad of fish in field.
Enhancement of dissolved phosphorus release from sediment to lake water by Microcystis blooms--an enclosure experiment in a hyper-eutrophic, subtropical Chinese lake.
TLDR
The results indicate that Microcystis blooms induced massive release of P from the sediment, perhaps mediated by high pH caused by intense algal photosynthesis, and/or depressed concentrations of nitrate nitrogen (NO3-N).
Simultaneous determination of microcystin contaminations in various vertebrates (fish, turtle, duck and water bird) from a large eutrophic Chinese lake, Lake Taihu, with toxic Microcystis blooms.
TLDR
This is the first to conduct simultaneous determination of microcystin (MC) contaminations in multi-groups of vertebrates (fish, turtle, duck and water bird) from Lake Taihu with Microcystis blooms, indicating that toxicity of cyanobacteria may determine accumulation level of MCs and consequently fates of aquatic wildlife.
In situ studies on the bioaccumulation of microcystins in the phytoplanktivorous silver carp (Hypophthalmichthys molitrix) stocked in Lake Taihu with dense toxic Microcystis blooms
TLDR
Silver carp accumulated less microcystins in liver than other animals in the same site or other fish from different water bodies at similar level of toxin ingestion, and there was possible inhibition of the transportation of the most toxic MC-LR across the gutwall.
Nutrient dynamics and the eutrophication of shallow lakes Kasumigaura (Japan), Donghu (PR China), and Okeechobee (USA).
TLDR
The variable nutrient dynamics that the authors observed among the three study lakes appears to be typical for shallow lake systems, which indicates that a greater reliance on lake-specific research may be required for effective management, and a lesser role of inter-lake generalization than is possible for deeper, dimictic lake systems.
Seasonal dynamics of the hepatotoxic microcystins in various organs of four freshwater bivalves from the large eutrophic lake Taihu of subtropical China and the risk to human consumption

TLDR
There appeared to be positive correlations between the maximum MC contents in the hepatopancreas and the δ13C or δ15N of the foot, indicating that the different MC content in the liver might be due to different food ingestion, and the high risk of consuming bivalves in Lake Taihu.
