How often do you change your cellphone , laptop, or television? Do you know where the electronic waste goes? Is it processed properly or is it just allowed to pollute the environment? In modern times, electronic devices, including batteries, cellphones, cameras, computer equipment, air conditioners, game consoles, electric trains, refrigerators, hair dryers, fans, are usually damaged and their garbage is thrown away.
Reporting from the National Institute of Environmental Health Sciences, an estimated 40 million tonnes of electronic waste are disposed of each year. Electronic waste will continue to increase so that its careless disposal will have a negative impact on humans and the environment. The careless disposal of electronic waste can cause air, soil, water pollution and health problems in humans.
Electronic waste usually contains precious metals such as silver, copper and gold. These precious metals can be purified from electronic waste by burning or applying acids and chemicals. This purification process is called traditional recycling and produces dioxin, lead, and greenhouse gas hydrocarbons into the air as pollutants.
Reporting from the World Health Organization , inhaled lead will interfere with the performance of the brain, central nervous system, causing coma, seizures, kidney problems, infertility, and even death. Not only humans, plants and animals will slowly experience air poisoning as a result of purified electronic waste.
Soil and Water Pollution
Electronic waste that is dumped carelessly ends up on the ground as well as in water and releases large amounts of toxic metals. Electronic waste contains toxic heavy metals such as mercury, lead, barium, cadmium, lithium and arsenic which are harmful to living things.
Heavy metals will enter the soil, pollute plants and seep into aquifer rocks (groundwater sources). In waters such as lakes, rivers, bays and seas, these heavy metals can cause death or harmful genetic mutations to living things. Heavy metals penetrate into plants, soil, water and animal bodies.
This makes humans who consume water, plants, meat, and breathe polluted air which will also be contaminated with heavy metals. Cadmium can cause respiratory problems, kidney damage, anemia, and anosmia. Reporting from the National Organization of Rare Disorders , arsenic can cause damage to the brain, nervous system, capillary bleeding, skin problems, muscle spasms, coma, and even death.
