Faced with the increasing advancement of technology, the production of cells and batteries has grown continuously. However, in their compositions they present highly toxic components called heavy metals, so when they are incorrectly discarded, they cause contamination in the environment and human health. Thus, this work aimed to show the impacts caused by the incorrect disposal of the same. The methodology involved research using articles, academic dissertations, journals and websites. A literature review was carried out between January and April 2022, in the following database: Google Scholar. With improper disposal, contact with moisture, water, heat and other chemicals is enough for toxic components to leak and mass contamination ensues. Taking as an example the environmental accident that happened in Bauru in 2002, where 314 children were contaminated by lead, causing blood lead and irreparable damage. In Brazil, there are currently some projects aimed at correct disposal, an example of which is recycling. In most treatment processes, a sorting takes place, with the aim of treating each type of electronic waste. This procedure (recycling) is promising and can be applied in serval places.
