It is beginning to infiltrate
10industry at a fast rate, and it’s a challenge for designers and also engineers.
11I wondered when a weakness will be revealed. Then I stomped on an article
12talking about harm in using LED technology. It looks like this magical
13technology is not so magical and eco-friendly.<p>A new study from the University of California indicates that LED lights contain
14toxic metals, and should be produced, used and disposed of carefully. Besides
15the lead and nickel, the bulbs and their associated parts were also found to
16contain arsenic, copper, and other metals that have been linked to different
17cancers, neurological damage, kidney disease, hypertension, skin rashes and
18other illnesses in humans, and to ecological damage in waterways.<p>Since then, I haven’t yet found any regulation for disposal of LED lights or any
19other regulation or standard. This might be a problem in the future. And it is a
20massive drawback. This might have quite an impact on consumer market.<p>Nevertheless, there is a potential, and I am sure the market will adapt. I also
21hope I will be reading documents regarding solution for this concern soon.<p><strong>Additional resources:</strong><ul><li><a href="http://ezinearticles.com/?Recycling-and-Disposal-of-Light-Bulbs&amp;id=1091304">Recycling and Disposal of Light Bulbs</a><li><a href=http://www.ehow.com/how_7483442_dispose-lowenergy-light-bulb.html>How to Dispose of a Low-Energy Light Bulb</a></ul></div></article></main><section><hr><h2>Posts from blogs I follow around the net</h2><ul><li><a href=https://utcc.utoronto.ca/~cks/space/blog/linux/NFSv4ServerLockClients target=_blank rel=noopener>Finding which NFSv4 client owns a lock on a Linux NFS(v4) server</a> — <a href=https://utcc.utoronto.ca/~cks/space/blog/>Chris's Wiki :: blog</a><div>A while back I wrote an entry about finding which NFS client owns
