In San Pedro Itzicán and Mezcala, communities of Poncitlán, girls, and boys urinate more than 14 pesticide substances. The results were obtained from the screening analysis applied this year gradually by the University of Guadalajara (UdeG) and the Jalisco Health Secretariat (SSJ)

At the beginning of the year, it was expected to study 24 thousand children from Lake Chapala, however, the coronavirus pandemic delayed the work and only covered 10%, per day it was expected to analyze between 250 to 500 children, but only 100 study per week.

“What we have found most are pesticides, not heavy metals. We have not found what is said to be arsenic, lead, what there is are pesticides, there are children who have up to 14 pesticides in urine out of 24 that we detect, and right now we have the possibility of detecting 60 in urine or blood, “said Felipe Lozano Kasten, a researcher at the Department of Public Health of the University Center for Health Sciences (CUCS) at UdeG.

For the academic, the presence of pesticides is a new factor that must be considered when investigating the causes of kidney inflammation that infants of these populations develop and that over time turns into kidney failure since previously only the presence was discussed of heavy metals in your body.

The study carried out revealed that there is also the presence of these substances in their clothes when washed with the water from Lake Chapala. In other words, they live 100 percent with agrochemicals.
