Sources of eutrophication
#Natural eutrophication.
Eutrophication is a process that is slowly occurring naturally in all lakes in the world, because all nutrients are received.
#Eutrophication of human origin.
Human discharges accelerate the process to make, often in a serious pollution problem. The main sources of eutrophication are:
*urban discharges, which are detergents and organic waste
*Livestock and agricultural discharges, contributing fertilizers, organic wastes and other wastes rich in phosphates and nitrates.
The degree of eutrophication
To know the extent of eutrophication of a given water is usually measured the chlorophyll content of algae in the water column and this value is combined with other parameters such as phosphorus and nitrogen and the value of light penetration.
Measures to prevent eutrophication
The most effective way to combat this type of pollution is to reduce the amount of phosphates and nitrates in effluents, using detergents with a low proportion of phosphates, using less amount of detergents, not over-paying fields, using agricultural waste and livestock as fertilizer, instead of pouring, etc. Specifically:
*Treating wastewater in WWTP (wastewater treatment plant), including biological and chemical treatments that remove phosphorus and nitrogen.
*Properly store manure used in agriculture.
*Use fertilizers more efficiently.
*Changing farming practices to other less polluting. For example, delaying the plow and prepare fields for cultivation to planting spring cereal crops in autumn claims to have the land covered with vegetation during the winter thus reducing erosion.
Reduce emissions of NOx and ammonia.
