Algae are known to accumulate both metals and organochlorine compounds. [1] Heavy metals can depress algal growth when they are present above a certain threshold level. They can also destabilize their cell membrane. This inhibits the cell division or causes the algae change shape. [2]
Organochlorine compounds can also inhibit photosynthesis and algae cell growth. However, there seems to be a wide range in the tolerance of algae towards these compounds. Therefore the compounds might be a threat to the algae biodiversity and seasonal cycles of algae. [3]
