Nevertheless the arsenic contained in food (amounts ranging from 0.01 to 1.5 mg/kg of dry weight) has a different influence: it carries out some positive metabolic function for our body. Mineral water refers to bottled spring water. Phyto-pharmaceuticals Phyto-pharmaceutical products are the most accused substances for ground water pollution. That's less than 1% of some bottled water! A possible lack of selenium can increase the risk of tumour and cardiovascular diseases. Some precautions can be taken to lower lead content in drinking water: flush the water before drinking it, since lingering water in pipes tends to accumulate lead; to avoid water dissipation it is recommended to collect the flushed water in bottles and tanks for a following use; do not use hot tap water for cooking, since hot water dissolve lead more easily than cold water; periodically remove clinker and slag from the pipes; to use an home water filter is certainly a good way for lead removal. Asbestos Asbestos can reach drinking water through natural sources, pipes built in a compound made of concrete and asbestos and from atmosphere. A nitrates water content of about 10 mg/l is considered normal and natural. The European Directive about drinking water for human consumption 98/93/EC states that the maximum allowed lead concentration in drinking water should decrease from the actual 50 mg/l to 10 mg/l within 25 December 2013. [4] Permitted is the removal of iron, manganese, sulfur and arsenic through decantation, filtration or treatment with ozone-enriched air, in so far as this treatment does not alter the composition of the water as regards to the essential constituents which give it its properties. Chlorine (Cl) Chlorine is an important constituent of organic liquid and a daily intake of 7-15 g of NaCl is recommended. Nitrates and nitrites Nitrates are the main source of nitrogen for plants and an essential constituent for nucleic acids and amino acids. Drinking 2 liters of water containing 20 mg/l of sodium you reach 40 mg, that is about the 5% of the total intake. In contrast to these well-known mineral water brands, Thank You Silver has a mineral content of only 10 ppm. The salt consumption in industrialized countries is considered much higher than the recommended levels (about 3.9 g/day on average). No additions are permitted except for carbon dioxide, which may be added, removed or re-introduced by exclusively physical methods. "Jalsujal-104" makes the water testier, wholesome and healthful drink and best for cooking. We are not going to spend too much time in the description of their use and abuse, but everybody should know cases of closed wells. Guidelines and directives for calcium, magnesium, and hardness levels in drinking ... Health, to address a number of questions relating to the nutrient composition of drinking water and the possibility that drinking water could in some circumstances … Minerals can enter surface or ground water through natural sources, industrial sewage, leach age from urban or agricultural areas, water pipes walls or even from domestic sources. "Jalsujal-104" mineral water powder composition is developed for water received from surface sources like river, pond of reservoir etc after conventional treatment using alum and chlorine for purification. 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. Hard water seems to bring to a lower asbestos loss compared to water poor in salts, which is much more corrosive. 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. Treatment and potabilisation plants work very well reducing these minerals to safe levels. 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. They are also in cosmetics, anti freezing products, glues, colours. To an important extent, the chemical composition of mineral waters is determined by the composition of the rock it is abstracted from. The water formula is H 2 O, two atoms of hydrogen and one of oxygen, but only distilled water has this structure. Can we rely on drinking tap water or it is preferable to buy bottled water? The recommended daily intake is 10 mg. Iron is usually contained in low amount in drinking water. 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. Arsenic (As) Arsenic can be toxic even in low amounts. The composition of mineral waters sourced from Europe and North America in respect to bone health: composition of mineral water optimal for bone Br J Nutr .

Here you could have a rough idea of mineral water compositions. Our body contains an average of 100 g of sodium which is an important metabolic regulator for nervous and muscular stimulations. Cadmium (Cd) Cadmium is a highly toxic heavy metal, considered carcinogen. 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. Available in 125 gram packed bottle. Rain water, snow and ice are quite similar to distilled water. The calcium fluoride presents in nature is very different from the sodium-silica-fluoride (Na2SiF6) added in drinking water, an industrial waste that is toxic and difficult to digest. Many toxic minerals are contained in water supplies, usually at high levels. 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. We can contribute to the reduction of this pollution source, using only the minimum necessary quantity or choosing biodegradable surfactants. Travelling to the mineral water site for direct access to the water is now uncommon, and in many cases not possible because of exclusive commercial ownership rights.

Major lead sources are paint, vehicle emissions, food and water. To accelerate chlorine dispersion you can pour the water from a tank to another repetitively or mix very quickly. Among the several brand on sale, which one should we choose? Aluminium (Al) Aluminium is very abundant on the earth, but is not important for human nutrition. People against drinking water fluorination argue that it is a violence that does not count individual choice freedom, not to mention the individual tolerance limit. Rain water, snow and ice are quite similar to distilled water. There is no evidence that the aluminium assumed through water is more soluble and then more easily digestible, than the aluminium contained in food. They are very resistant and can be found in tap water even is a treatment system is present. The WHO recommend a daily intake of 0.3 mg/day for a 60 kg person. Sodium, potassium, calcium, Mineral analysis of a few European mineral water brands; Red = high mineral content; blue = low mineral content. Selenium (Se) Even if selenium is considered a toxic element taken is high dosage, it is an important anti-oxidant. Tap water Bottled Water Drinking water alternative sources. There are more than 4,000 brands of mineral water commercially available worldwide. If you would like to have further information from health risks from drinking demineralized water, click here. Bacteria are carefully monitored in public water supplies, since they can be responsible of serious diseases as typhoid, cholera, hepatitis etc. Here and in the related pages you'll find all the answers to these questions. and their presence can be easily detected. Most of these compounds are toxic and many have been found in water reservoirs. Phosphates Phosphate in water originates from detergents and fertilisation and a level higher than 0.1 mg/l indicates pollution. No disinfection treatment is permitted, nor is the addition of any bacteriostatic agents. The third group of microorganisms commonly found in water are parasite, as giardia and cryptosporidium.
