What are the effects of lead, zinc, calcium, magnesium and asbestos on the human body?
The utility model has the advantages that the drinking water problem can be solved conveniently. Disadvantages: 1. drinking machine cooking repeatedly, not only a waste of electricity, but also easy to form thousands of boiling water, affecting the health; 2. out of the water, into the air inside the machine, then the impurity in the air will enter, forming two pollution; 3. even 2 cases without above (which is not possible), also can only solve the drinking water problem, while you wash the rice, washing dishes, cooking, soup kitchen water problem is still not resolved, it is necessary to use the tap water pollution two. Water purifier.
Organic pollutants bring great harm to the human body. At present, the pollution of organic pollutants in water sources is very serious in our country. More and more kinds of organic substances are found. According to statistics, there are about 70 thousand kinds of common organisms. Organic matter in water has protective effect on the stability of colloid, improve water treatment, not only increase the difficulty, and the small molecular organic toxic and hard degradation, bioaccumulation, and three caused by strong (carcinogenic, teratogenic and mutagenic) or chronic toxicity, harm of organic compounds the human body is often lag, from discovery to illness requires a long time, even 20 - 30 years. In addition, halogenated compounds are produced when organic compounds are combined with chlorine disinfectants, and many have been identified as an inducer of cancer. Among them, mainly volatile three halogen methane and non-volatile halogen acetic acid, the latter carcinogenic risk is the former 50 - 100 times. Drinking machine and water purifier from drinking machine: water dispenser water heating device is a water machine, you can use bottled water as a water source, you can also add a cleaner at the top (that is accurate, the net bucket) tap water added as a water source.
Water softeners mainly solve the problem of scale caused by hard water, so household water softeners are quite popular in the United States where the water quality is hard. Domestic soft water machines enter China, with the water quality of the north and northwest regions as the main market, and they are in the embryonic stage. At present, the product terminal sales are mainly concentrated in Beijing and Shanghai regions. The classification of natural water and natural water can be divided into two types: hard water and soft water where there are lots of calcium and magnesium ions (inorganic minerals) water is called hard water, otherwise known as soft water. If the water hardness by containing sodium carbonate or magnesium bicarbonate caused by water, this is called temporary hard water; the water if the hardness of containing calcium and magnesium sulfate or chloride caused called permanent hard water. In brief, water containing less than 10 milligrams of calcium carbonate belongs to a high standard of soft water.
