Ecologist Tasks Media On Ozone-Depleting Products

An ecologist, Mr Abdullahi Aremu has urged the media to sensitise Nigerians on the dangers of using refrigerators and air conditioning units which emit ozone-depleting substances like chlor-ofluorocarbons into the atmosphere.
Aremu, the Director-General, Advocacy for Environmental and Sanitation Integrity, an NGO gave the advice in an interview with newsmen in Abuja.
The ecologist advised Nigerians not to buy products that contain chlorofluorocarbons; as such devices released toxic chemicals which depleted the ozone layer.
He said that the depletion of the ozone layer was a global environmental challenge which posed serious dangers to the entire human community.
“Therefore, if you are out for shopping, don’t buy aerosol products containing chlorofl-uorocarbons.
“Check your fire extinguishers to ascertain if halon or halogenated hydrocarbon is the main ingredient.
“I am urging the people to dispose of their old air conditioning units and refrigerators that use chlorofluorocarbons to function, as these devices release toxic chemicals into the atmosphere,’’ he said.
Aremu describ-ed chlorofluorocarbons as one of the primary causes of the depletion of the ozone layer.
“Industrial products, including solvents, soaps, spray aerosols, insulating foams, ‘take-away’ containers and cooling utilities, such as refrigerators and air conditioners, also use chlorofluorocarbons.
“Over time, the toxic chemicals accumulate in the atmosphere and are carried by wind into the stratosphere,’’ he said.
He said that once  chlorofluorocarbons were in the stratosphere, their molecules were broken up by the Ultraviolet (UV) radiation from the sun which released chlorine atoms.
“Depletion of ozone layer does not affect a region or a country the whole world is vulnerable to it.
“The increase in the levels of ultraviolet rays lead to the high incidence of skin cancer and eye-related problems,’’ he said.
Aremu also said that fertilisers and pesticides produced nitrous oxide, which also contributed to the depletion of the ozone layer.
