Are tap water sources contaminated? Where do these unsubstantiated stories originate?

What exactly is what is a “glyphosate” herbicide?

Glyphosate (ingredient named “glyphosate Iopropylamine sal”) is a herbicide for farming and gardening throughout the world including Japan. It is absorbed by the leaf and stem greens, migrates towards the roots and then withers the entire plant. It is not selective and every plant will be killed when it is applied to their leaves. Glyphosate-based herbicides are often offered by pesticide firms because the patent period for their ingredients has expired. All glyphosate-based herbicides are proven and tested.

One of the attributes of glyphosate is “safety” it is extremely safe for animals through a mechanism which inhibits the action of plant-based enzymes (not found in mammals). Furthermore, the chemical solution has the capacity to be absorbed by the soil and become food for microorganisms. https://pesticide.maff.go.jp/agricultural-chemicals/details/14360 The chemical can also be distinguished into carbon dioxide, water and other substances. Because it allows no-tillage cultivation, it is recognized as a pesticide that helps reduce greenhouse emissions of greenhouse gases.

Glyphosate in tapwater

Is there glyphosate in tap water?

Weekly Shincho stated in April 2020 that “In Japan, there’s no standard value left for glyphosate present in tap water. グリホサート There’s only the value that is targeted.” This value is higher than other pesticides and nations and drinking water sources are is contaminated. I wrote an article stating that there is. There has been speculation that high concentrations could remain in tap water. However, this is not the case.

First, glyphosate is not an “standard” value. It’s only an “target” value. Tap water has not detected glyphosate with a concentration higher than 0.2ppm (1). A Ministry of Health, Labor and Welfare study found that the tap water in Japan does not contain glyphosate with levels of more than 0.02ppm. http://www.fsc.go.jp/emerg/inryousui_glyphosate.pdf There is no danger of being detected.

Additionally, the soil decays the glyphosate at a rate of halving within two days. https://search.rakuten.co.jp/search/mall/除草剤+グリホサート/ This means that it can be transferred to waterways and rivers at the same concentration and will not cause any harm to the environment.

Safe tap water in Japan

The tap water of Japan is known as safe around the world. It’s safe to drink tap water as is. There are 51 requirements for inspection, and the water supply is under strict quality control. The pH difference between water is what determines whether it is acidic, neutral or alkaline. Japan’s water quality standards require the tap water to be close to neutral (5.8+ and 8.6+). There is still the possibility that iron rust may be found in your pipes that supply water.

How is tapwater produced? Tap water typically uses river and dam water as its primary water source. The water collected in the water purification plant gets sterilized by injecting chlorine and then removing impurities via precipitation and filtering. The tap water is then piped to homes.

Story of Japanese standard value for residues of pesticides

The glyphosate residual standard value for wheat is 5ppm in Japan. However, it was 5 to 5 ppm from December 2017. There are opinions like “We loosened that to 30ppm by 6x and despised the health damage.”

Tap water glyphosate

The standard residual value of glyphosate equals the international standard.

グリホサート But the reality is that we did not loosen the standard, but modified it to match the standard residual value that is the international standard. Japan imports wheat in large quantities from the United States, Canada and South America. The importer, who is the largest producer of wheat in the world regulates its use at 30ppm. The standard Japanese value is 5ppm. Anything that is higher than this standard will be banned. This could lead to reduced supply of wheat and may cause Japanese food products being at risk. So, we have revised the standard value to be in line with the international standards. Also, safety is not an issue with current standards.

You need to have a good understanding of the chemical glyphosate

To prevent consumers from being in a hurry to be influenced by emotions regarding pesticide residues, it is essential to acquire the correct knowledge that is based on research done by experts. It is also essential to not let gossip distract from your healthy lifestyle.
