Seasonal variations of heavy metals content in muscle and viscera of green-lipped mussel Perna viridis from Da-Peng Bay Lagoon in Taiwan.

As a natural lagoon, rich in biological resources including fish, crabs, and bivalves, Da-Peng Bay Lagoon receives the discharges from the neighboring rivers, Kao-ping, Dong-gang, and Lin-Bian, which have harmed the ecology and reduced the water quality of the lagoon. This study analyzes seasonal variation of heavy metals concentration (As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn) in the muscle and viscera of the green-lipped mussel Perna viridis from Da-Peng Bay Lagoon. Data from this study may provide information on the use of Perna viridis as a bioindicator for heavy metals pollution in the lagoon.

Tributyltin distribution and producing androgenic activity in water, sediment, and fish muscle.

This study investigated the concentrations of Tributyltin (TBT) in water, sediment, and fish muscle samples taken from Kaohsiung Harbor and Kaoping River estuary, Taiwan. TBT concentrations in water and sediment samples ranged from less than 18.5 to 34.

Heavy metals in bivalve mollusks collected from Da-Peng Bay Lagoon in south-southwestern Taiwan.

In this study, concentrations of several heavy metals (Cu, Pb, Zn, Ni, Cr, and Cd) were measured in Katelysia hiantina, Anomalocardia squamosa, Perna viridis, Anadara antiquata, Paphia undulata, and Sanguinolaria diphos bivalve mollusks from Da-Peng Bay Lagoon near the south-southwestern coast of Taiwan. The metal pollution index (MPI) values were highest and lowest in winter and autumn, respectively. The MPI value in the viscera of P.

Variation, correlation, and toxicity of phenolic endocrine-disrupting compounds in surface water.

This study investigated the variation in toxicity of phenolic endocrine-disrupting compounds (EDCs) and determined the correlation between their concentrations. All twenty-four samples acquired from a polluted river contained five phenolic EDCs. The EDC nonylphenol (NP) concentration was found to be the highest (4.

Total estrogenic activity and nonylphenol concentration in the Donggang River, Taiwan.

We report a survey on the occurrence and distribution of nonylphenol (NP) and 17beta-estradiol equivalent quotient (EEQ) concentrations in Donggang River, Taiwan. Concentrations of NP were measured with a high-performance liquid chromatography/fluorescent system and EEQs were carried with an MVLN cell line. Concentrations of NP ranged from less than 93 to 511 ng/L; EEQs ranged from less than 0.
