Our water is polluted and toxic

How is it that the quality of water in nature (but also that we consume) will be so degraded ? Who to blame ? What are the consequences for our health and our environment ? Global warming affects the quality of the water ?

The facts

And after the study of the’ASEF (Health environment France Association) from 2010, 10% surface waters of the France (rivers, rivers, Lakes, etc.) are without pesticides, 27% are poor to average and 10% are of very poor quality. 53% groundwater (groundwater), pesticides and 24% require special treatment before being consumable.

Who to blame ? And what are the consequences ?

1) Agriculture

Intensive agriculture requires large amounts of fertilizer (nitrates, phosphorus, etc.), of pesticides (herbicides, insecticides, fungicides) that contaminate the environment (soils, water courses, etc.). The France is the first European consumer of pesticides in tonnage, According to the INERIS (National Institute of the industrial environment and risks). Between 70 000 and 110 000 tonnes of active substances spilled per year on our territory, 90% come from agriculture. Consumption doubled between 1970 and 1990.

“66% nitrate pollution is of agricultural origin” stresses the report by ASEF. Nitrates are transformed in the body into nitrite. They poison the blood and cause methemoglobinemia (or blue disease) by oxidizing the haemoglobin of blood which can no longer attach oxygen disrupts cellular respiration. Related to some pesticides can cause long-term cancers, According to the CNRS (National Centre of scientific research).

The toxicity of pesticides is still poorly known because they form a family of hundreds of molecules very different which, degrading in nature, to generate yet other. “The uncertainty [door] on the long term effects of small doses but repeated” explains the CNRS.

2) Livestock

Intensive farming causes large amounts of manure containing nitrogen matter, phosphorus and bacteria that also contaminate the nature. L’InvS (Institute of sleep health) States that’There is a link between the spread of acute gastroenteritis and the quality of the tap water, to know the rate of fecal matter in the water (see the epidemic in the batch in 2000 and the balance the InvS waterborne outbreak of 2008)


Furthermore, livestock is stuffed to medicines for more often prevent it infections (and not treat) and promote growth. These antibiotic residues, and other, are also serious contaminants. The ASEF report states that “the importance of the drug releases to water is poorly known today”.

3) Medicine

Discharges from livestock drugs, fish farms (see exhibits – Trim all risks in video library), added hospitals, pharmaceutical and chemical industry, and the man ! Indeed the consumption of drugs has ceased to grow, According to a comparative study of the Direction of the Research Evaluation and statistics (DREES) from 2006, the France is the biggest consumer of drugs in Europe. But these are mainly releases from hospitals which are very worrying because contain some radioactive products and anticancer which almost do not degrade.

Specialists suspect antibiotics to be at the origin of resistant bacteria. They realize also has this medication make the most vulnerable fish species to infectious agents and find qu’one “feminization” fish species occurs thus harming their reproductive qualities.

Size problem : the sewage are not designed to treat the traces of drugs in water. “So far, no drug is on the list of priority to analyze drinking water pollutants” According to ASEF. In a more general manner found in the water coming out of the conventional wastewater treatment plants, in concentrations greater than 100 NG/L, 1.5% priority substances, 30% organic molecules and 90% pharmaceutical substances !

4) Industry

Nitrogen is also rejected by the manufacturers of fertilizers and explosives, metal processing industries and agro-industries. 12% nitrates are drawn from industry and an important part of pesticides (weed control) comes from companies that maintain roads, parks, the gardens and the railways.

Certain metals released by the industry (lead, chrome, Mercury, cadmium, nickel) are very harmful to humans and the environment. Heavy metals are not eliminated by the body. Even if these substances are present at very low doses, the fact of ingest them daily “can be the cause of serious diseases” According to the CNRS.

Children are, for example, far more sensitive than adults to lead and can thus develop lead poisoning. It is a disease that affects the growth, the behavior, the development of the central nervous system and intellectual development. Of highest concentrations in the body, lead causes disorders of reproduction, transmissible and kidney failure. Lead can also bind to the bone in our body and to combine, consequent brutal poisoning if returned in the blood lead, which mainly affects the elderly and pregnant women, says the CNRS.

What are the consequences of global warming ?

All this adds climate change causing an increase in temperature of water courses, the seas and oceans and by this fact, promotes the development of some unwanted organisms (bacteria, toxic algae, etc.). Bathing water and the products of the sea (fish, crustaceans, molluscs, etc.) becoming less good quality.

The second consequence of global warming is to reduce the water supply. With a drying, the rivers and groundwater level drops, increasing the concentration of pathogens and other pollutants. Water supply became more difficult and the health risks are increased.

When I drink more d’ one litre of water (tap) I have the right side below the ribs, as if I had gallstones. but after exams I did in
have not. as soon as I drink less water I feel nothing !

A qoi is due ?????????????????

Perhaps because of the chlorine and aluminum in tap water; and or limestone levels in tap water. Note that the minerals in tap water are eliminated 95% in urine; The minerals that are considered 80% by the body are present in the solid bolus; kidney function is to remove impurities from the body and require a slightly mineralized water source for cleaning the body ; more water is highly mineralized, more kidneys will be asked to filter and wash Limestone

Hey well I say, attention to the drinking water and also for the shower faucet …

Hello, between what I read on filtering carafes and what I just read, There are what get lost. Indeed, I just read an article on the water filtered by jugs Brita who said that the tap water is not so bad is believed and contains calcium, component required for our body and which is removed by filtration. The article above which tells us that we drink water very polluting and dangerous to health. Then, who to believe?

Is it possible to tell me what influence may have water on the health of the child and the adult that contains 100 times the authorized railway standard (analysis of a departmental hygiene laboratory result) Bue during 8 years until the change of the network of supply and distribution of water by the Union of my municipality ?

No worries for man that assimilates 1% the amount of trace elements found in drinking water. Unlike seawater …
Man can not assimilate that 1% inorganic water minerals. So only organic minerals ” végétabilisés ” are assimilated by the human being and it must be made through the plant

Would love your thoughts, please comment.x
