Consequences of the incorrect disposal of electronic waste when growing flower seedlings

The improper disposal of batteries has numerous consequences for the environment, since they contain potentially toxic metals that can be leached, infiltrating, and contaminating the soil layers, the groundwater, as well as the fauna and flora of nearby regions. Therefore, studies were conducted to simulate and analyze soil contamination by the release of potentially toxic metals from the incorrect disposal of alkaline batteries in the environment, in similar natural conditions, by doing leaching tests in fertilized soil resembling a landfill. Therefore, in this paper a simple experiment is proposed for sensitizing students toward the consequences of an incorrect disposal of batteries in the environment.
