A study prepared by the Department of Pharmacology, Faculty of Medical Sciences, State University of Campinas (Unicamp), São Paulo collected 90 urine samples from men and women exposed to glyphosate. The survey did not found significant traces of the urine herbicide of rural workers in Mato Grosso.
Of all samples collected in 12% quantifiable levels of glyphosate were found. In these samples, the highest value found was 0.007mg / kg. According to the National Agency of Sanitary Surveillance (Anvisa), the Acceptable Daily Intake (IDA) is 0.042mg / kg. The results were analyzed by the professors Angelo Zanaga Trapé, medical toxicologist, and Paulo César Pires Rosa, chemist and pharmacist.
The report states that the time these workers were exposed to glyphosate prior to the study did not influence the amount of residues, as the highest level was obtained from candidate No. 19 (7.13 ng / mL) with time of exposure of 1 year and 9 months, while the candidate of nº 29, with 10 years exposure time, did not obtain any level of quantifiable residue.
“As studies suggest an absorption rate of approximately 20%, one can consider that the intake may have been up to five times greater than the internal dose found. Thus, the highest level of residue found, 7.13 ng / mL could be equivalent to an external dose of up to 0.003 mg / kg. That is, 7.14% of the acceptable daily dose, “reports the researcher. Trapé stressed that “no study shows a causal relationship between being a farmer and having cancer.”
Dr. Paulo Rosa explained that the research method was validated to give security in the results and that the device used to verify the samples was certified. “We still have to expand to a larger number of samples. But this is a pilot project that shows the safety of glyphosate, “he said.
Although studies have minimized the use of the herbicide, Judge Luciana Raquel Tolentino de Moura of the 7th Federal Court of Justice in Brasilia, to determine the suspension of registration of all products that use abamectin and glyphosate.
Last Friday (24), the Attorney General’s Office (AGU) filed an appeal against the injunction that suspended the use of the product, but no opinion has yet been given.
