Endocrine disruption chemicals(EDCs) are world widely used and detected in ecosystem. Organotin compounds, Nonylphenol(NP) and Bisphenol A(BPA) are suspected as endocrine disruption chemicals.
Organotin compounds are widely used as antifouling paint to prevent adherence of sedentary organisms to ship's hull and other structural surfaces immersed in seawater. Organotins such as tributyltin(TBT) and triphenyltin(TPT) are considered to be dangerous chemicals because of their deleterious effects on non-target marine organisms.
Nonylphenol and bisphenol A are suspicious endocrine disrupting chemicals causing estrogenic effect and genital trouble etc.
In the study, a study for accumulation characteristics and level of EDCs such as organotin compounds, NP, BPA, in fish were performed.
Organotin compounds(tributyltin, triphenyltin and their metabolism products), NP and BPA were determined in fish collected from local markets and the coast in Incheon, Gunsan, Masan, Yeosu, Pohang and Jeju. Two fish species such as mullet, Mugil cephalus and flounder, Paralichthys olivaceus were sampled as alive. Organotins, NP and BPA concentrations in muscle and liver of each fish were analysed.
Butyltin compounds were detected in most of the samples of fish muscle and liver. But phenyltin compounds were detected in some of the samples. The concentrations of tributyltin(TBT) compound in fish muscle and liver were in the range of 1.06 ～ 21.16 ng/g-wet wt. and 6.77 ～ 703.06 ng/g-wet wt., respectively. Those of triphenyltin(TPT) compound in muscle and liver ranged from < 0.1 to 70.32 ng/g-wet wt. and <0.1 to 316.33ng/g-wet wt., respectively. Organotin residues in liver of were mostly higher than in muscle. The highest concentrations were detected in the liver of flounder collected from Pohang. The compositions of butyltin compounds in fish were different according to muscle and liver, but those of phenyltin compounds were similar. The concentrations of BPA in fish muscle ranged from <0.1 to 1.45 ng/g-wet wt. but those of NP were not detected.
The bioaccumulation effects of endocrine disruption chemicals(EDCs) such as TBT compound, NP, and BPA on flounder, Paralichthys olivaceus. The exposure experiment with the flow through system was performed to examine the effects of single and multi-chemicals exposure.
In the muscle of flounder exposed to TBT compound, the concentrations of TBT compound were significantly increased to compared with the control value in each system of single and multi-chemicals exposure after two months. Those in liver of flounder were more remarkably accumulated than the case of muscle. TBT compound in muscle of the low level of EDCs were highly accumulated in single exposure of TBT than the multi-chemicals exposure with NP and/or BPA.
In flounder reared in high level of EDCs, the concentrations of TBT in muscle were increased in multi-chemicals exposure system. Those of TBT in liver of flounder showed lightly decrease in multi-chemicals exposure system. The metabolites of TBT, DBT and MBT were also concentrated in muscle and liver of flounder after exposure.
Nonylphenol and bisphenol A in muscle of flounder were accumulated in exposure system of high level of EDCs. NP and BPA in muscle of flounder after depuration period were significantly decreased to compared with TBT compound.
