- Abstract
- Antifouling agents including tributyltin (TBT) compound and its derivatives have been used for many
years, but the usage of TBT in Korea was legally restricted in 2003, due to its significant environmental impact.
Following this, many new alternative antifouling agents have been used. In this experiment, four major antifouling
agents were selectively analyzed to study their release in seawater and tidal flats on the Korean Peninsula. These
new antifouling agents were extracted from the seawater and tidal flats using a liquid-liquid extraction method
and microwave extraction, respectively. The measured concentrations of Irgarol 1051, Sea-Nine 211, Dichlofluanid
and Chlorothalonil ranged from N.D.-23.80 ng/L, N.D.-15.30 ng/L, N.D.-61.69 ng/L and N.D.-4.19 ng/L in the
seawater samples and from N.D.-159.45 ng/g, N.D.-476.57 ng/g, N.D.-59.79 ng/g and N.D.-21.27 ng/g in the tidal
flat samples, respectively. Interestingly, these new antifouling agents were not detected in any area in the tidal
flats at Pusan, whereas a certain amount of them was found in the seawater.
