In aquatic systems, primary production is typically measured using one of four main techniques:

Low phosphate levels are an important limit to growth in some aquatic systems.

Browne et al. (in press) have looked into the structuring of aquatic systems for water treatment.

The effect on plant life and aquatic systems is also expected to be devastating.

Lead can also have marked environmental impacts, especially in aquatic systems.
