Abstract

 

This paper showed, that the samples recovered from the subsurface water always contained much fewer bacteria than those sampled from the surface microlayer. The neustonic bacteria are more resistant to the heavy metals ions than bacteria collected from subsurface water. The mean data obtained allow a statement that copper ions provoked the least response, while lead and cadmium ions - the greatest ones.

 

Key words: heavy metals, surface microlayer, neustonic bacteria
