Freshwater pollution

1. Freshwater species

1.1. The types of species that could become affected by water pollution in freshwater ecosystems are:

1.2. insects

1.3. crustaceans

1.4. fish

1.5. amphibians

1.6. arthropods

1.7. plants

1.8. fungi

1.9. bacteria

1.10. algae

1.11. viruses

2. In order to solve this problem we need to use less water every day. For example, a car wash, brushing teeth, washing your face, cleaning the house, and the like. Also, we need to use ecological oil for cars, start to run a line of specialized tanks for disposal in areas where a lot of fresh water, but even if that does not work, then we will have to go to extreme measures, namely to put on duty patrol to monitor offenders and surveillance cameras.

3. it is an environmental factor, cause water. especially fresh water is part of our ecology with you

4. The concentration of dissolved O2 highly depends also on the amount of pollutants, because most water pollutants cause low oxygen levels in freshwater. These pollutants make it difficult for species to live, and many aquatic organisms, especially fish, die when dissolved oxygen levels fall below 5 ppm. There are a few natural sources of pollutants present in aquatic ecosystems. But mostly, freshwater ecosystems may become unbalanced by factors due to human activities. Human activities affect the bioavailability of chemicals to organisms, cause temperature fluctuations, and modify rainfall, pH and salinity. Water plays a key role in diluting pollutants and because of that superiority as a solvent, it also means that water-soluble wastes pollute water easily. For instance, runoff from nearby land provides freshwater life zones with an almost constant input of organic material, inorganic nutrients, and other pollutants. Some 1500 substances have been listed as pollutants in freshwater ecosystems. Plants and animals can’t live without freshwater, because all organisms are made up mostly by water. A tree for example is about 60% water by weight and most animals are about 50-65% water. Also each of us needs huge amounts of water.
