A typical computer monitor may contain more than 6% lead by weight, much of which is in the lead glass of the cathode ray tube (CRT).
What computer component contains a lot of lead?
The central processing unit in a computer contains toxic substances, and lead is found in circuit boards.
What parts of a computer can be recycled?
Recyclable materials in computers
The glass monitor, keyboard, plastic or aluminum casing, cables, CD-ROM drive, ray tube, power cord, circuit board, batteries and printer cartridges are all recyclable computer materials.
Do computers contain lead?
Computers contain toxic heavy metals such as lead, cadmium, mercury and chromium, all carcinogenic and not easily degraded.
What is lead used for in computers?
Lead is used in three primary PC applications: it makes up 37% of the tin-lead solder that connects computer chips to printed circuit boards, it is used as a radiation shielding in monitor glass, and it is sometimes used as a plastic stabilizer in PVC cabling.
Do electronics contain lead?
Most smartphones and other electrical or electronic products contain small amounts of lead, which doesn’t sound like a big problem on its own. But when there are many billions of such products, either in daily use or gone astray, the total sums up to very large amounts of lead — which is a toxic heavy metal.
Is there lead in laptops?
In laptops and other electronics, there are heavy metals known to cause brain damage even at low dose, including lead, nickel and cadmium. There are also toxins less known to the public—bromine, phthalates and arsenic acids—that serve as wire coatings in your devices.
Which is most easily recyclable component of a computer?
Just like they sound, microprocessors are very small, but don’t let their size fool you. They are actually the easiest computer part to recycle since the only metal contained in them is (a very small amount of) gold. A mix of hydrochloric acid and nitric acid is used to separate the gold from the ceramics.
What parts of a laptop can be recycled?
All of the cables and cords that you use with your laptop, including the power cord, audio cables, peripherals like a keyboard and mouse, A/V and HDMI cables, and pretty much anything else that you can plug in, are all recyclable.
Why should materials be recycled?
Recycling reduces our need for new raw materials.
It also uses up a lot of water and energy. When we recycle, we extract less, which conserves many of our precious (and finite!) natural resources, including trees, water, oil and metals. The more we recycle, the more we protect our resources!
How much lead is in a computer?
Your typical piece of electronic equipment — especially one like a PC with many circuit boards — may contain up to 8 pounds (3.6 kilograms) of lead, along with lower levels of mercury, arsenic, cadmium, beryllium and other toxic chemicals [source: Downing]. These elements are all toxic at varying exposure levels.
What chemicals elements are found in computers?
The metals contained in PC’s commonly include aluminum, antimony, arsenic, barium, beryllium, cadmium, chromium, cobalt, copper, gallium, gold, iron, lead, manganese, mercury, palladium, platinum, selenium, silver, and zinc.

How is arsenic used in computers?
Arsenic is often found in integrated circuit boards where it is used because of its efficiency as a conductor. … Lead was traditionally used in solder on printed circuit boards – it has been banned in the EU since 2006 – and lead oxide is used in cathode-ray tubes.
Do circuit boards contain mercury?
And circuit boards often contain poisonous metals that are used in the manufacturing process, including mercury and lead. Both of these can have profound health effects in humans. Mercury toxicity is such a problem that some countries have proposed banning the metal completely.
