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. Dr. Stuart M. McGill takes a slightly different approach. All of this says that in every house, every apartment you need to install water purification systems. 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.

Americas Honey

Historical evidence indicates the existence of bees in different countries. However, until 1500 the presence of bees is fixed only within the Old World. Since the XVI century, the family of the honeybee were brought by settlers in the Americas, and later in Australia. Our country's territory was inhabited by bees from the west. Believe that their ancestors had remained in the post-glacial period in the delta areas Danube. From there, the current area covered steppe and forest steppe zone of Ukraine. Other species of bees on yield performance of honey bees.

Indian wild bees are bred and used in Japan, China, Vietnam, etc. The other two species bees – a giant and dwarf bee bee – live only in tropical southern Asia. The above four species of bees are united in one genus belonging to the family of bees. Honey Bee is the next place in the taxonomy of the animal world: type – chlenistonogieklass – nasekomyeotryad – pereponchatokrylyesemya – pchelinyerod – pchelavid – honey. Provide some benefits as other relatives of these unique insects. In particular, we have a very widespread in nature bumble bees, which pollinate most effective red clover and a number of other cultures.

Bee – listorez adapted to collect food for the flowers of alfalfa. Its specially bred in some countries, in some farms to opylitelnoy of arranging artificial nests, shop for incubation and storage of the brood. Osmium – a useful kind of bee is involved in pollination of flowering plants in the spring. The methods of cultivation and use them for pollination of fruit trees and alfalfa fields. All of these beneficial insects need to protect nature and help in their reproduction. Most related to human activity honeybee, which began to grow on apiaries. Protect bees from diseases of various adverse conditions, and if need be – fed. All this requires a certain amount of funds, the organization of bee-keeping, beekeeping facilities construction, manufacturing hive mastering knowledge. Beekeeping – an important branch of agriculture. More information about breeding and keeping of honey bees can be read at medosbor.rf.
