So far, we've discussed the concept of e-waste, its types, causes and legal framework. You might be wondering, why so much emphasis on e-waste though?
Well, most electronics are made with toxic chemicals and metals that are perfectly safe when in use, but that’s not the case when they are being tossed away;
When disposed of improperly, e-waste can negatively impact ;
The Air:
The burning, dismantling, shredding or melting of e-waste materials by scavengers or the informal sector to extract valuable components of e-waste leads to the release of dust particles or toxins, such as dioxins, into the environment that causes air pollution and damages respiratory health.
For example the burning of wires to extract copper.
The air pollution caused by e-waste impacts some animal species more than others, which may be endangering these species and the biodiversity of certain regions that are chronically polluted.
The Soil:
When e-waste is dumped on the landfills or open areas, it breakdowns and during this process release heavy metals like lead or cadmium which could leach or seep into the soils.
This affects plant growth and development in these affected areas and invariably animals. They could also get into human food through the food web causing negative health implications.
Ground Water/ Water bodies:
After soil contamination, heavy metals from e-waste, such as mercury, lithium, lead and barium, then leak through the earth even further to reach groundwater. When these heavy metals reach groundwater, they eventually make their way into ponds, streams, rivers and lakes. Through these pathways, acidification and toxification are created in the water, which is unsafe for animals, plants and communities even if they are miles away from a recycling site. Clean drinking water becomes problematic to find.
Humans:
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. It can also considerably affect the nervous and reproductive systems of the human body, leading to disease and birth defects.

Although the long term impacts of e-waste are not yet known, there is still cause for concern judging from the aforementioned. What can we do then?
Join us next week as we will be preferring solutions to this growing menace.
