Fertilisers and Pesticides

Fertilisers

The process of Eutrophication

The process of Eutrophication cont.

Biochemical Oxygen Demand (BOD). This measures the rate of oxygen consumption by a sample of water, and therefore gives a good indication of eutrophication. A high BOD means lots of organic material and aerobic microbes, i.e. eutrophication

The nitrate concentration falls during spring and summer and rises during autumn and winter Less algal growth as autumn begins Possibly all plants have died

Pesticides

Include: Herbicides Insecticides Fungicides Bactericides

Pesticides Persistence + Lipid solubility = Bioacculmulation

Bioaccumulation E.g DDT
