Data on the level of contamination of the Albanian seashore with PSP biotoxins (saxitoxin and derivates) as well as the heavy metals (Hg and Cr) are given. Lysosome membrane destabilization test has been the method of choice in the present study. A relatively low retention time of the used red neutral dye in some selected monitoring areas was detected at the distance of 50 m offshore indicating a high level of the biological stress. Whereas at 200 m distance the retention time the sensibly increases. Comparably higher levels of Hg and Cr were detected at 50 m offshore distance. The high level of PSP biotoxins in some selected monitoring areas, where sampling of water and bivalve molluscs was performed has impacts on the health.
