Fresh Water Pollution

Contamination of fresh water in most cases remains invisible, because contaminants are dissolved in water. Aluminum compounds that are in earth, as a result of chemical reactions, get to fresh water. Huge damage Fish Stocks cause floods that wash away harmful to fish magnesium from the soil of meadows. But the volume of natural contaminants in comparison with man-made null and void. Thousands of chemicals fall into the water basins annually with unpredictable effects. new chemical compounds. Elevated concentrations of toxic heavy metals (chromium, lead, mercury, cadmium), polyphosphates, surfactants, petroleum, nitrates and phosphates, pesticides in the water can be detected.

Different ways to get fresh water contaminants: a result of spills and leaks, deliberate dumping, accidents. To a large the degree of water polluted due to traditional use in household water filters, filters of scale polyphosphates, which lead to accelerated proliferation in the water of toxic blue-green algae. As a result, This river is dying all living creatures. Around the city there is a rapid contamination of groundwater. In terms of biochemical oxygen demand (BOD) is measured pollution of fresh water-that is, how much oxygen from the water absorbs the contaminant.

The degree of oxygen starvation of aquatic organisms to evaluate this indicator. According to World Health Organization, eighty percent of diseases in the world are caused by unsanitary condition and unsuitable water quality. Particularly acute problem of water quality in rural areas, about ninety percent of all rural residents consistently use for bathing and drinking contaminated water. All of this says that in every house, every apartment you need to install water purification systems. Hear other arguments on the topic with קרוס ריבר. Water purification systems for household REDD purify water from heavy metals, organic pollutants, also serve as filters for scale. They help clean the water is very effective, and drains, domestic water, passing through such household filters do not contain polyphosphate.
