“…These affectations attack the systems of the human body and each of the organs in general, showing cases of neuropsychiatric affectation among children from 0 to 4 years old and a decrease in the total weighted IQ [43]. In addition, deterioration is observed in the functions of the central nervous system with neuromotor impairment and the appearance of symptoms similar to Parkinson's, the endocrine system with symptoms of renal and hepatic insufficiency and genetic alterations, mutagenic, teratogenic, and carcinogenic effects [40,44,45].
