Detailed explanation-1: -b)E-waste that is improperly disposed of by residents or businesses also leads to toxins entering groundwater. Toxins like lead, barium, mercury, and lithium are considered carcinogenic(having the potential to cause cancer). This impacts humans that rely on this water.
Detailed explanation-2: -As mentioned, electronic waste contains toxic components that are dangerous to human health, such as mercury, lead, cadmium, polybrominated flame retardants, barium and lithium. The negative health effects of these toxins on humans include brain, heart, liver, kidney and skeletal system damage.
Detailed explanation-3: -E-waste is hazardous to human health since it contains mercury, cadmium, lead, chromium, beryllium, and arsenic (Ilankoon et al., 2018). These pollutants can easily seep/percolate into groundwater and the ecosystems, causing environmental harm (Ilankoon et al., 2018).
Detailed explanation-4: -Therefore, e-waste can be a significant threat to the environment. Toxic metals (e.g., lead, mercury, nickel, and cadmium) are released to the environment from the e-waste and eventually enter into soil, sediment, groundwater, and surface water.
Detailed explanation-5: -About 70% of the heavy metals (including lead, mercury and cadmium) found in landfills come from e-waste*.
