-
Indicators: Sediment Toxicity
Phosphorus, like nitrogen, is a critical nutrient required for all life. Phosphate (PO4), which plays major roles in the formation of DNA, cellular energy, and cell membranes (and plant cell walls). Too much phosphorus can create water quality problems.
-
Indicators: Sediment Mercury
Sediment mercury is mercury that has become embedded into the bottom substrates of aquatic ecosystems. Mercury is a common pollutant of aquatic ecosystems and it can have a substantial impact on both human and wildlife health.
