Metales Pesados presentes en Pilas Tipo Botón y su Comportamiento en el Agua y en la Tierra

Abstract

Experimental study was conducted analytical laboratory, identifying the substances contained in the electrolyte of the batteries sold in the domestic market and the degree of human toxicity and environmental (eco-toxicity).
Also conducted experiments on the behavior of these cells unarmed and exposed to the action of acid water,neutral and alkaline, in order to determine the mobility of heavy metals into the media.
Also batteries were buried whole and disarmed in natural soil columns, being subjected to the action ofartificial rain with distilled water, analyzed the leachate.
The study takes a period of 10 months and still not found heavy metals in the leachate. However, wasimmediately the appearance of increases in pH due to the alkaline nature of some batteries.
We also found significant changes in electrical conductivity and metal findings were not mentioned in the literature.
After completion of studies is planned to transfer the results of the program to provincial, municipal and community to give them a technical and scientific base to enable them to set environmental policies.
