Electronics Contain Mercury and Lead
Over the past several decades, technology has evolved quickly enough to make one’s head spin. It wasn’t all that long ago that color television sets were a big deal. Today, most households have HDTVs, DVD players, gaming systems and computers. We’re all enthralled with the latest and greatest technology, and when something new comes along, we’re ready to get rid of the old stuff to make room for it.
The problem is that electronics are not so easy to dispose of. Some of the items, particularly the less bulky ones, end up in the trash. But big or small, most electronics contain things that should not go to the landfill. Two of the most common materials in electronic components, mercury and lead, are extremely hazardous.
Mercury is extremely toxic. High doses of mercury can be fatal. Low doses can affect the central nervous system, immune system, kidneys and liver. Exposure to small amounts of mercury in the womb can cause brain damage in a developing fetus. Mercury is found in LCD displays, switches, batteries and circuit boards.
Lead is well known for its effects on mental development in children. It is also toxic to the kidneys, nervous system and reproductive system. Lead is found in cathode ray tube monitors and television sets. These items may contain as much as eight pounds of lead. Other sources of lead in electronics include circuit boards and batteries.
Keeping Mercury and Lead Out of Landfills
Technology doesn’t appear to be slowing down, so the trend of replacing our gadgets every few years is likely to continue. But the trend of those electronics and the hazardous waste they contain ending up in the landfill doesn’t have to. These items can often be reused, and if their useful life has ended, they can be recycled.
Computer equipment can be upgraded as new technology becomes available. Some manufacturers, however, make it difficult. They design their products without room for expansion, necessitating the purchase of a whole new system. But if we choose to buy only from companies that make upgrading a viable option, we can keep adding on to the same system for years to come.
Electronic items that are not obsolete are good candidates for donation. Schools, charities, civic groups and churches are often in need of computers and media equipment, and donations are tax-deductible in some cases. Donating extends the useful life of the product, and that saves natural resources and reduces the amount of hazardous waste in landfills.
Non-functioning and obsolete electronics should be recycled. It may take some effort to find an electronics recycler, but the benefit to the environment is well worth the trouble. Some manufacturers offer lease and takeback services. Ask about these options when purchasing electronics.
Mercury and lead can end up in the environment when electronics go to the landfill. By disposing of electronics responsibly, we can do our part to protect the earth and the health of its inhabitants
