The Athens Medical Association added its voice on Monday to those warning about smog levels in Athens due to the high number of households using fireplaces to keep warm and the weather conditions, which are not helping to disperse air pollution.
Doctors said that readings in several parts of the capital showed that smog levels were above the warning limit. They said there were similar readings in Thessaloniki, Patra and Volos.
The association warned people to take care regarding what materials they burn in their fireplaces and called on the government to create a more comprehensive policy to deal with the problems people have in heating their homes.
On Sunday, the Health Ministry warned the elderly and asthma sufferers that smog levels in Athens and other urban areas were at dangerous levels due to weather conditions and the high number of people burning wood to stay warm.
The ministry warned that people over the age of 65 should limit their physical activity and that asthma sufferers might need to use their inhalers more frequently because of the smog.
The Health and Environment ministries had issued a statement on Saturday night asking households to limit the use of fireplaces to prevent the build up of smog.
