Environmental Impact But as the phosphate loading continues and there is a build-up of phosphate in the lake or surface water ecosystem, the aging process of lake or surface water ecosystem will be accelerated. The overproduction of lake or water body can lead to an imbalance in the nutrient and material cycling process (Ricklefs, 1993).

Phosphate rock contains varying amounts of innate Cd and some of that Cd is transferred to fertilizer products during the manufacturing process. In addition to other anthropogenic activities (e.g. mining Zn bearing ores, combustion of fossil fuel, waste incineration, land application of sewage sludge and manure, and irrigation water), P fertilization can add Cd to agricultural soils.

Effects of Fluoride Pollution. The source of the problem lies in the fact that raw phosphate ore contains high concentrations of fluoride, usually between 20,000 to 40,000 parts per million (equivalent to 2 to 4% of the ore).

But if too much phosphate fertilizer is applied to soil, excess phosphorus can easily find its way into water systems via storm drains and plumbing. Grass clippings and leaves from plants that have been grown in soils with an overabundance of phosphorus will release their phosphorus into water, leading to algae and bacteria outbreaks and water contamination issues.
