The "fully export-dedicated" plant imported mercury (about five tonnes a year) from Bethlehem Apparatus, Pennsylvania, U.S., made thermometers and exported them to the U.S. for re-export to other countries. At its peak, the factory produced 500,000 pieces of thermometers a year; about 165 million pieces were exported between 1984 and 2001. - http://www.frontline.in/static/html/fl2017/stories/20030829001808200.htm
