Glyphosate’s metal-chelating activity causes bioaccumulation of toxic metals in the body, resulting in an estimated 400 000 cases in Sri Lanka and 20 000 deaths Dr Eva Sirinathsinghji
Sri Lanka is set to partially ban glyphosate-based herbicide use following a new peer-reviewed study linking it to a fatal chronic kidney disease epidemic badly affecting the country . Kidney problems have been further documented in other global regions, prompting an earlier complete ban by El Salvador late last year . A complete ban was initially proposed, but due to plantation sector representatives claiming a shortage of agricultural workers that would not sufficiently manage weeds without glyphosate, the government has now limited the ban to disease endemic areas . Even Brazil, one of the largest growers of glyphosate-tolerant genetically modified (GM) crops has now filed a law suit by Federal Prosecutors to ban glyphosate along with 8 other dangerous pesticides . It is becoming increasingly difficult for government regulators and glyphosate producers to justify the use of this herbicide when other nations are banning the chemical outright in order to protect their citizens.
Glyphosate can impact human health in a number of ways, one of which is through its potent metal chelating abilities. Indeed, glyphosate was originally patented by Stauffer Chemical Co. in 1964 (U.S. Patent No. 3,160,632)  for this very function. Chelating mineral ions can lead to nutritional depletion in plants and animals, which has already been shown to cause health problems in both. In the case of this kidney disease epidemic, its chelation of metals such as arsenic in the water supplies is now though to lead to their bioaccumulation in the body, resulting in kidney failure and even death, as proposed in a new study  by Channa Jayasumana (Rajarata University, Sri Lanka), Sarath Gunatilake (California State University, USA) and Priyantha Senanayake (Hela Suwaya Organization, Sri Lanka) published in the International Journal of Environmental Research and Public Health. Glyphosate has also been linked to many other health problems including cancers (see  Glyphosate and Cancer, SiS 62), infertility (see  Glyphosate/Roundup & Human Male Infertility, SiS 62), along with neurotoxicity, reproductive problems, birth defects, and other problems (see  Ban GMOs Now, special ISIS report).
