In this respect, the Undersecretary of Public Health, Cristóbal Cuadrado pointed out that "it has been a long-awaited study on the health situation of the three communes of Quintero, Puchuncaví and Concón, in which we will be analyzing the different effects on health that prolonged pollution in the area could have had. Let's study heavy metals like lead, arsenic, but also other common health conditions, respiratory situations, among others. In this way, this study is going to be very useful, it will be developed for a year and will provide us with high quality information to be able to measure what are the main health problems of the community, from this we will be able to design an organized response of the health system, identify what kind of investment we need to make in the area to improve access to primary care, to the hospitals in the area, to respond in a timely manner to the needs that long-standing exposure to pollutants in the area may have generated", Pointed out.

Sandra Cortés, professor of the Department. of Public Health of the PUC and researcher responsible for the study explained that a communication campaign will be deployed to invite the community to participate in a complete evaluation of their state of health that will be carried out by very well trained people from that university. "We hope to recruit people who have lived at least 5 years in the commune and we are going to take a blood sample from them, a urine sample to know your state of health with clinical parameters more related to sugars, fats; plus a couple of quizzes about your residential history, in the case of adults, and your work history. Also, we are going to do tests of respiratory function and with that we are going to calculate different parameters that will have a communal representativeness, that means that they will give an image of what are the most important diseases that occur in the population of these three communes and what social factors, of the environment, of your residential or work history have to do with your current state of health".

For its part, the Seremi of Health of the Region of Valparaíso, Mario Parada Lezcano added that "this study will be complemented by a census study of the population of children, girls and adolescents from the three communes; and will also be complemented by another study, retrospective to specifically search for events related to neurological diseases, oncological and respiratory. All this battery of very rigorous investigations will allow to deepen the diagnosis and have a clear panorama of all the affectation of the community to better implement the public policies that exist and implement new policies that allow transforming this area into a recovery zone ".
