The water formula is H2O, two atoms of hydrogen and one of oxygen, but only distilled water has this structure. Aluminium concentration is usually lower than 200 mg/l in drinking water. Chemical organic compounds directly originates from plant or animal matter. To reduce the daily sodium intake it would be more logical to change your nutrition: i.e. Aluminium (Al) Aluminium is very abundant on the earth, but is not important for human nutrition. Mineral analysis of a few European mineral water brands; Red = high mineral content; blue = low mineral content. According with some research 10% of fluoride doesn't deposit in teeth and bones, but in organisms such as kidneys. Every day we drink water or we eat watery food to replenish our metabolic reserve. Selenium (Se) Even if selenium is considered a toxic element taken is high dosage, it is an important anti-oxidant. Water can naturally contains small quantities of sulphates, but they are mostly transferred in water bodies from the atmosphere and in the atmosphere form road traffic, industries and energetic production. Mineral water may usually be still or sparkling (carbonated/effervescent) according to the presence or absence of added gases. In 1945 the addition of fluorine in drinking water began to be experimented in New York State, followed by Australia and some areas in UK, with the declared purpose of preventing dental caries in population. Sulphates Sulphates are sulphuric acid salts combined with metallic ions. It is essential in our body for teeth and bones formation, blood coagulation, right functioning of our nervous system. Magnesium (Mg) Magnesium is, with sodium and calcium, among the cations most commonly found in drinking water. There are more than 4,000 brands of mineral water commercially available worldwide. Il Punto d'incorntro, 2003, Health risks from drinking demineralised water, Distributieweg 3 2645 EG Delfgauw The Netherlands Phone: +31 152 610 900 fax: +31 152 616 289 e-mail: info@lenntech.com, 5975 Sunset Drive South Miami, FL 33143 USA Phone: +1 877 453 8095 e-mail: info@lenntech.com, Level 5 - OFFICE #8-One JLT Tower Jumeirah Lake Towers Dubai - U.A.E. It can have total mineral content similar to the bottled water shown above or even much higher concentrations. quality of the water used for their reconstitution has been acknowledged by the Scientific Committee on Food, SCF, of the European Commission (2). Here you could have a rough idea of mineral water compositions. They are also in cosmetics, anti freezing products, glues, colours. Calcium ions are contained in almost all spring, drinking water. Fluorine values useful for our body are very close to toxic values, so a dispense not aimed and personalized can cause high risk of overdosing and chronicle poisoning, with consequent skeleton deformation, spots on tooth enamel, osteosclerosis, neurological disorders, damages on the thyroids and even tumours. The water formula is H 2 O, two atoms of hydrogen and one of oxygen, but only distilled water has this structure. Major lead sources are paint, vehicle emissions, food and water. 2009 Apr;101(8):1195-9. doi: 10.1017/S0007114508061515. Its toxicity is strongly linked on the concentration. Tap water, which may be hard or soft, is delivered via a complex system of pipes, pumps and purification systems to homes and buildings through individual taps. Not very much is known about the compound of phyto-pharmaceuctics, but metabolites can be much more toxic than water. Mercury can be released in ground water or in surface water by industrial waste water discharge in rivers and estuaries, by leach age from toxic landfill, by mercury emissions from volcanoes, seismic underground activity, incineration and fossil fuels combustion. If you would like to have further information from health risks from drinking demineralized water, click here. Our body contains an average of 100 g of sodium which is an important metabolic regulator for nervous and muscular stimulations. Aluminium can have toxic effects even in small quantities. Surfactants Surfactants are the substances used in detergents to lower the surface tension of the water, allowing it to wet the clothes better. Water forms form 50 to 60% in weight of our body and play an active role in all the vital processes of our body: it allows digestion, food elaboration and waste elimination. Traditionally, mineral waters were used or consumed at their spring sources, often referred to as "taking the waters" or "taking the cure," at places such as spas, baths, or wells. Copper (Cu) Copper is an essential element for our health, but it is toxic at high concentration. Mercury (Hg) Mercury can or can not be toxic, depending on its chemical bonds. Drinking calcium poor water is considered dangerous for the risk of coronary diseases. Health Risks from Consumption of Demineralised or Low-mineral Water .....150 III. That salt comes from mineral deposits that find their way to the ocean through the water cycle. The recommended daily intake is 10 mg. Iron is usually contained in low amount in drinking water. Possible increasing (lower than 200 mg/l) are not to be considered harmful, even if they make the water not nice to drink and give an unpleasant reddish colour. Microbiological pollution Microorganisms include bacteria, virus and parasite. A particular type of infection which can be transmitted through water is legionella. The USDA’s Nutrient Data Laboratory (NDL) conducted a study of the mineral content of residential tap water, to generate new current data for the USDA National Nutrient Database. Everyone knows that ocean water tastes salty. No minerals may be added to this water. Tap water Bottled Water Drinking water alternative sources. Well water and tap water mineral content varies widely from location to location. Here and in the related pages you'll find all the answers to these questions. No disinfection treatment is permitted, nor is the addition of any bacteriostatic agents. A nitrates water content of about 10 mg/l is considered normal and natural. Water fluorination is prohibited in Belgium, Denmark, the Netherlands and France; in Spain and Germany local authorities handle every decision and in Italy there is no specific law on this matter. Subsiding sedimentary basins are normally filled with fossil marine waters of varying composition. Health effects caused by hard water, very rich in calcium and magnesium, are unknown. The U.S. Food and Drug Administration classifies mineral water as water containing at least 250 parts per million total dissolved solids (TDS), originating from a geologically and physically protected underground water source. Rain water, snow and ice are quite similar to distilled water. The more calcium and magnesium ions that are dissolved in water, the harder it is said to be; water with few dissolved calcium and magnesium ions is described as being soft. The mercury released in the atmosphere is very light, so it can reach long distances from the source and fall again on the soil through rain, entering water bodies.

All rights reserved, Plant Inspection & Process Optimalisation, Separation and Concentration Purification Request, health risks from drinking demineralized water. The WHO recommend a concentration lower than 20 mg/l. Drinking 2 liters of water containing 20 mg/l of sodium you reach 40 mg, that is about the 5% of the total intake. Today, it is far more common for mineral water to be bottled at the source for distributed consumption. The World Health Organisation recommend a minimum calcium daily intake of about 700 mg. Other inorganic toxic substances. The composition of the mineral water depends on the composition of the underground rocks through which it flows. Perhaps the most important substance dissolved in the ocean is salt. Lead (Pb) Lead is poisoning even in small amounts for microorganisms, interfering with haemoglobin formation and with the functionality of central nervous system. This pollution can happen through the contact of water with porous surfaces or synthetic materials that are an ideal media for microorganisms. The ideal environment for the bacteria of legionella phneumofila is included between 37 and 45 C. Source: "Acqua buona, Acqua sana", Gudrun dalla Via, Ed. Depending on geochemical processes however, similar types of rock may lead to different types of mineral water. to eat only integral sea salt, more equilibrate and rich in mineral salts at home, and to avoid precooked food, always rich in refined salt. If when you open the tap you smell the chlorine odour typical of swimming pools, it is recommended to pour the water in a large tank and to leave it open or semi-open for about half an hour. The salt consumption in industrialized countries is considered much higher than the recommended levels (about 3.9 g/day on average). They are very resistant and can be found in tap water even is a treatment system is present. Viruses are very abundant in water supplies as well. Selenium is useful to attack free radicals and then prevent aging. The risk occurs particularly in showers or Jacuzzis.
