India is becoming a dumping ground for the hazardous Cathode Ray
Tube (CRT), popularly called picture tubes. They were earlier used in computer
monitors and erstwhile television sets. In the age of LEDs and LCDs, these
obsolete CRTs present an alarming trend as its glass is being recycled for
making bangles, marbles, bottles and other day to day items. This has been
observed in a recent study conducted by Toxic Link, (NGO working on the hazards
of
e-waste). The CRTs have been found to contain high percentage of lead and
other heavy metals which are major health and environmental threats to the
country today.
The study
points out that due to high presence of lead, the CRT monitors have been declared
“hazardous” and subsequently “banned” from land-fills and incinerators in most
developed countries. Due to a shift in technology, most countries including
those in Asia, have shifted to new projection systems (LCD, Plasma), thereby
creating a huge pile of this hazardous waste.
