Abstract
Results of a monitoring program revealed that there was a steady level of paralytic shellfish poisoning (PSP) toxins in the marketed shellfish samples in Hong Kong and the eastern coast of South China Sea. The PSP contents varied from 300 μ/kg to 2,500 μ/kg. According to high-power liquid chromatography (HPLC) analyses, the major toxins included: CTXs, STX1, STX2, GTX2, GTX3, and GTX4. By means of similarity analysis it was discovered that the PSP toxins in shellfishes collected from Macau, Hong Kong, and Mirs Bay were of the highest similarity. The toxins in shellfish samples that were collected from Daya Bay and the eastern coast of South China formed another similarity group. Results of the present study suggested that PSP causative phytoplanktons and the PSP-contaminated shellfish sold in Hong Kong markets were mainly imported from the eastern coast of South China Sea.
