Electronic waste recycling is the process of disassembling or shredding unwanted electronics that have reached the end of their useful life or have become obsolete. According to the EPA, the U.S. generated 3.42 million tons of e-waste in 2012. Only 1 million tons (29.20%) of the electronics were recycled.
When e-waste is recycled, toxic particles are released and disperse into the air. This increases the risk of human exposure as these chemicals may enter the soil-crop food pathway. The soil-crop food pathway is considered, “One of the most significant routes for heavy metals’ exposure to humans.” Since e-waste recycling creates fine dust that may contain various hazardous metals, it is the responsibility of both the employer and employee to practice e-waste recycling in a safe and responsible manner. Chemical hazards and potential health effects found in common household electronics (such as computers, monitors, keyboards and mice, TVs and mobile devices) include:
· Lead dust – Anemia, kidney damage, high blood pressure, nerve and brain damage, miscarriage, birth defects.
· Mercury vapor – Nerve and brain damage, birth defects.
· Cadmium dust – Kidney disease, bone problems, lung cancer.
· Beryllium dust – Lung disease.
· Flame retardant dust – Possible thyroid hormone problems.
While e-waste recycling can cause permanent and serious physical and health problems, companies can work towards a safer and greener approach by transitioning to elements that are biodegradable, thus decreasing the risk of chemical exposure.
