PHYCOLOGY AND HEAVY‐METAL POLLUTION
1. All heavy metals, including those that are essential micronutrients (e.g. copper, zinc, etc.), are toxic to algae at high concentrations.

UNLABELLED The present study compares protein diversity within three Anabaena species (Anabaena doliolum, Anabaena sp.PCC 7120 and Anabaena L31). 2-DE based analysis of 256 protein spots in control… Expand
Heavy Metal Tolerance in Algae
Algae are often exposed to heavy metal pollution due to the disposal of industrial and domestic wastes into waterways. Many algae growing in metal–polluted environments display an ability to tolerate… Expand
