Human Health Risk Assessment of Heavy Metal Concentration in Seafood Collected from Pattani Bay, Thailand.

A significant impact of marine pollution is the contamination of seafood which has raised concerns due to its potential human health risks. This current study investigated seasonal bioaccumulation of 9 heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) in 14 commercially important seafood species, including 4 fish, 5 molluscs, and 5 crustacean species. Samples were collected from Pattani Bay, Pattani province, Thailand, during the dry (July 2020) and wet (February 2021) seasons.

Comparative study of four species (Bagridae, Siluriformes) from Thailand: insights into their karyotypic diversity.

Karyotypes of four catfishes of the genus Scopoli, 1777 (family Bagridae), Fowler, 1937, Roberts, 1992, (Bleeker, 1846) and (Bleeker, 1851), were analysed by conventional and Ag-NOR banding as well as fluorescence in situ hybridization (FISH) techniques. Microsatellite d(GC), d(CAA), d(CAT) and d(GAA) repeat probes were applied in FISH. The obtained data revealed that the four studied species have different chromosome complements.
