With the growth of the industrial sector and the production of consumer goods in the last decades, there has also been an increase in the chemical contaminants eliminated in the environment reaching the water supply. However, such substances can act as endocrine disruptors causing serious damage to living organisms. Especially in the case of human beings, an important source of exposure to such substances, occurs through the water that supplies their homes, however the processes to which the water distributed to the population is subjected in the treatment plants are not able to eliminate these contaminants to in order to avoid potential damage to human health. Given the above, this project aims to develop an electrochemical sensor with high efficiency for monitoring species of environmental interest in public water samples. The making of the device will be carried out from the screen printing process widely used to obtain miniaturized devices and large-scale production. In order to improve the electrochemical performance of the manufactured device, it is intended to modify the electrode surface with nanomaterials derived from carbon and silver.
