For thirty years, they still feed the chronicles, despite scientific evidence of their lack of toxicity. Do nutritionists not suggest consumingvegetables, some of which can contain a hundred times more nitrates per kilo than a liter of tap water? Even if serious studies lead to note the beneficial effects of nitrates on inflammation, immune capacities, and its implications in cardiovascular protection, the will of the public authorities is to track down nitrates, like the recent decision of the Government of the Netherlands which threatens 500 to 600 farms to close to limit nitrogen levels. Agriculture is still presented as the main cause of water pollution.

Where does water pollution come from?
Tired of such inconsistencies, a few farmers from the Rural Coordination proceeded, in the presence of a bailiff on November 24, 2021, to take water samples from the outlets (1) of three wastewater treatment plants in medium-sized towns in Charente.

Similarly, on February 28, 2022, they took water from the outlets of two hillside reservoirs in southern Charente, only fed by runoff from the surrounding fields.

These analyses, entrusted on the day of the sample to a COFRAC-accredited laboratory in Nantes, looked for 120 chemical or biological products potentially present in the water...

Although nitrate itself is not carcinogenic, it is the precursor of dangerous substances.

Nitrates NO3- are only transformed into nitrites NO2- when they are in the presence of an extremely abundant microbial population, more precisely when the number of bacteria in the medium concerned exceeds 106 ml-1 [Cf. sections of May 7, 11 and 14, 2010].

The presence of nitrites in the spinach and lettuce leaves analyzed by the authors simply shows that they have been left at room temperature for too long. There is therefore no need for unnecessary new regulations.

The only health risk from nitrates is indirect. It concerns the infant, when in the bottle the nitrates are transformed into nitrites following a microbial proliferation exceeding 106 germs ml-1. The risk of infant methemoglobinemia exists when the bottle is prepared with "squalid" well water. It also exists if the infant is presented with a vegetable soup (carrots, spinach) that has escaped standard hygiene rules. When kept in the refrigerator, the bottle or the small pot already opened should not remain there for more than twenty-four hours. When left at room temperature, the bottle or jar that has already been opened should not stay there for more than six hours.

The concept is classic. When the classic hygiene rules are not respected, considerable quantities of NO2- nitrites can appear in the leaves of vegetables, the levels observed being able to exceed 2000 mg NO2- kg-1 [Hölscher and Natzchka, 1964; Filer et al., 1970; Hunt and Turner, 1994].

The preparation of a bottle or a small pot for the infant therefore responds to a single principle: respect the rules of hygiene.

The International Agency for Research on Cancer (IARC) declared in 2015 that deli meats enriched with nitrites were carcinogenic. Michèle Rivasi explains in her press release "thatnitrate and nitrite are never carcinogenic themselves. Regardless of the dose of ingestion, these two substances never directly cause cancer - neither in animals nor in humans. However, after being injected into meat, nitrate and nitrite decompose and become associated with the meat material. It is then that they give rise to three types of carcinogenic molecules: nitrosyl iron, nitrosamines, nitrosamides."

Nitrates and nitrites are molecules that occur naturally in water, air and soil. But it is also found in fertilizers, manure, chemical oxidizing agents, explosive compounds and in certain foods, either naturally occurring or added.

These additives, onceinjected into the meat, heated, combined with organic components produce carcinogenic substances, nitrosamines, and these nitrosamines cause colorectal cancer

For health reasons, the standards impose constraints on farmers to store and spread agricultural effluents when no one is worried about otherwise dangerous city waste!

It should be noted that the regulations impose grass strips on the banks of streams on farmers to limit the runoff of nitrates into the water of the rivers. Meanwhile, nothing is being done to deal with city stormwater that pours directly into waterways, washing pet feces, passers-by spit and leaking car sumps onto impermeable asphalt surfaces. .

as with everything, it is the synergy that occurs in living organisms, dose or not, that brings benefits or risks. A person allergic to peanuts, for example, is not because of the massive doses he absorbs, but even if there are only traces of these or others.

Desensitization (or specific immunotherapy) consists of administering, over a long period (several years), extracts of allergens in progressive doses, so as to stimulate the immune system and make the person tolerant to the substance.
