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 musselPerna viridisfrom Da-Peng Bay Lagoon. Data from this study may provide information on the use ofPerna viridisas a bioindicator for heavy metals pollution in the lagoon. The heavy metals concentrations were greater in viscera than in muscles of the green-lipped musselPerna viridis.Results showed that the mussel is capable of accumulating high contents of Cu and Zn. Generally, the order of concentrations in the muscle by season was Zn > Cu > Cr or As. In viscera, the general order of concentrations was Zn > Cu > Pb or Cr or As. Mercury was not detected in winter and spring in muscle and viscera. Cadmium displayed significant variation with season. There was also significant correlation between tissue concentration and heavy metals, including Cu, Pb, Zn, Ni, Cd, and As. [ABSTRACT FROM AUTHOR]

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 34.1 ng Sn L−1and from 2.44 to 29.7 ng Sn g−1weight per weight (w/w), respectively. Concentrations in the TBT‐contaminated fish muscle samples ranged from 10.8 to 79.6 ng Sn g−1w/w. The TBT concentrations in fish muscle were higher than those in water and sediment samples. The fish muscle/water TBT bioconcentration factor (BCF) ranged from 590 to 3363 L kg−1. Additionally, the water samples were assessed for androgenic activity with an MCF7‐AR1 human breast cancer cell line. The androgenic activity ranged from 0.94 to 3.1 ng‐dihydrotestosterone per litre water (ng‐DHT L−1). Higher concentrations of TBT in water and sediment samples occurred in the dry season, but the androgenic activity had higher values in the rainy season. [ABSTRACT FROM PUBLISHER]
