For years there have been professional noses in the perfume industry, today
they are also being employed in environmental protection.
The environment monitoring station of Panyu will soon employ people with
sensitive noses to sniff out foul
gases in the atmosphere, and with the aid of scientific equipment, give a more
accurate reading of air quality.
The station's Vice-Director Liu Jingcai said, "Foul gases have already become
one of our major pollutants they are unleashed by the chemical, rubber, and oil
refining industries, garbage processing sites and sewers. They cause damage to
the human respiratory system." He
said, "Our equipment can accurately analyze the density of a particular gas but
with mixed gases they are not reliable and it cannot tell the effects on
humans."
Liu and his team of 11 professional noses, have received training from
experts working in top laboratories dealing with environmental protection and
air pollution control.
He said, "Now we can differentiate between hundreds of smells that may make
people ill, before making an assessment on their density."
"We have honed our smelling skills for various sources of pollution. It will
help in the detection efforts of our bureau, and hopefully, bring more pollution
violators to justice."
"The work is quite unpleasant," he said. "We have to stay in a lab smelling
those awful gases repeatedly."
Liu and his team will soon be issued certificates allowing them to officially
start their careers as professional noses.
The certificates will be valid for three years at a time, as one's sense of
smell diminishes with age.
