The market for anti-pollution masks is in full swing and the number of users is rising steadily. Depending on the type of mask and its filters, the effectiveness of the anti-pollution masks vary greatly. This protection also has several disadvantages, such as the heating of the breathed air and a condensation of the sweat inside the mask.
Dr. Cristina Paunescu (from the Faculty of Pharmacy of Paris) and al. published a few days ago, in Indoor Air papers, the results of a large field study for particles pollution measurements. A study very rare in its ambition for statistically relevant data acquisition! A cohort of 96 children, aged 9 and living in Paris and suburbs, was gathered to monitor the ultrafine particles and black carbon they breathed over 24 hours of their everyday life, with portable sensors of scientific quality. The results are revealing : school and home are the places where children are the most exposed.
The French are the world's largest consumers of medicines. 42% of those over 18 years old take at least one drug everyday. This tendency to over-medication and overprotection weakens the body and the immune system. Is that true also for air purification?
