GOVERNMENT has expressed concern over the continued use of ozone depleting substances, which is contributing to skin-related cancers and eye complications.
The Montreal Protocol On Substances That Depletes The Ozone Layer was adopted by the international community in September 1987 to gradually reduce, and eventually eliminate, the production and consumption of man-made chemicals, which negatively affect the ozone layer.
Addressing journalists during a media workshop in Kadoma yesterday, National Ozone Unit Manager in the Ministry of Environment, Climate, Tourism and Hospitality Industry, George Chaumba, said the use of these substances comes with health complications.
“There are some man-made chemicals that are used in refrigeration and air conditioning and these are used worldwide,” said Chaumba. These substances, once released into the atmosphere, react with ozone molecules, depleting the ozone molecules and, once they are depleted, it will lead to an increase in UltraViolet radiation, getting to the earth surface.
“Once UV radiation gets to the earth surface, it will affect human beings, causing eye cataracts, skin cancer and suppression of the immune system. Eye cataracts are caused when the UV radiation heats the eyes causing damage to the lense and that will lead to partial or permanent blindness.
“There is also damage to DNA material, leading to skin cancer.”
He added: “Other effects range from damage to synthetic materials, such as auto mobile car paints, roof materials, green houses.
“As the National Ozone Unit in the Ministry of Environment, Climate Change, Tourism and Hospitality Industry, we are reaching out to communities, informing them about the dangers of ozone layer depletion and what they can do to protect themselves from excessive UV radiation.
“We are also raising awareness on the use of ozone and climate -friendly appliances in homes, such as the use of refrigerators, freezers and cold rooms that use climate friendly products.”
