Bioaccumulation and physiological responses of the Coontail, Ceratophyllum demersum exposed to copper, zinc and in combination.

Ceratophyllum demersum is a submerged aquatic angiosperm which is fast growing in contaminated water. This plant has no roots and so takes up nutrients from the water column without the complicating factor of differential shoot/root uptake of nutrients. This study aimed to compare the bioaccumulative capacities of Cu, Zn and their combination by C.
