THE IMPACT OF ACID RAIN ON AQUATIC ECOSYSTEMS
AGRICULTURE
Modern agriculture makes sure of many chemicals
called agrochemicals. These include pesticides, herbicides and fertilisers.
All of these are water-soluble and can cause pollution in water bodies, with a variety of consequence for humans and the enviroment.
PESTICIDE AND HERBICIDE POLLUTION
Pesticides are made to kill living things but not people. Humans have a lot of things in common with some living organisms, pesticides can sometimes harm humans.
Insecticides are a kind of pesticide that kill insects.
Pesticides are water - saludable, so water pollution made by these agrochemicals would be a big concern.
POLLUTION CONTROL AND LEGISLATION
Pollution control
Refuse disposal systems such as sanitary landfills, emission control systems for automobiles, sedimentation tanks in sewerage systems, the electrostatic precipitation of impurities from industrial gas, or the practice of recycling.
Legislation
Puts pressure on the polluters to find ways to reduce the pollutants.
Example of the bi-national Great Lakes water quality agreement which was devised in 1972.
EUTROPHICATION
Nutrients such as nitrate and phosphate can enter water from many sources, including farmland, industry and domestic outputs. In addition, organic matter can enter water directly as sawege and from other sources.
This is called an algal bloom. When the algae die there is an increase in organic matter in the water. These bacteria use up oxygen, lowering its level in the ater.
REDUCING ACID RAIN
To reduce SO² emissions, low-sulfur varieties of fossil fuel should be used.
A reduction in the production of acid rain-causing gases is achieved when substitutes for fossil fuels are found to produce energy.
