Gas in the TV screen is more toxic than coal vapor

Nitrogen trifluoride (NF ₃ ) is commonly used in toxic TV industry 17,000 times more than carbon dioxide (CO2) and every year has a production volume of 4,000 tons.

Michael Prather, director of the Institute of Environment at the University of California (USA), said the production caused NF _{3 to} be booming and will double next year. But unlike greenhouse gases such as CO ₂ , SF ₆ , PFC . NF _{3 is} not restricted in the Kyoto protocol on environmental protection.

However, scientists have not statistics how many tons of NF ₃ emissions are released into the atmosphere every year. And Air Products, the maker of NF ₃ for electronics companies, said this number is very small.

For consumers, experts still recommend not opening or smashing CRT monitors or liquid crystals.
