Indoor air purifiers have multiplied in recent years. All promise to help us breathe at home a healthier air. The offer is so wide that navigating the vast array of available air purifiers can be confusing. TEQOYA helps you to choose the right air purifier.
Carbon dioxide, nitrogen oxides, volatile organic compounds .. There are numerous pollutants and they are harmful to your health: irritation, tiredness, stress, migraine, headache, asthma, respiratory problems, etc. What effects do they have on your skin ? How good are the so-called "anti-pollution" cosmetics? The purpose of our article is to provide some answers.
An air purifier is made to remove pollutants from the air. At issue is the impacts of air purifiers on the environment. Do they necessarily reduce air pollution ? Are we sure that air purifiers do not pollute more while trying to take pollution out of the air ? This is a thorny question and TEQOYA provide some answers.
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?
In December, France had its longest pollution peak for at least ten years. The concentration of fine particles remained at a level 4 to 5 times higher than usual. This phenomenon was due to a seasonal increase in particulate emissions, particularly dependent on heating. The meteorological conditions, favourable to the pollutants maintenance near the ground, reinforced it.
On Friday 18 November in Marrakech, the negotiators from 196 countries put an end to COP22. The objective of the 22nd Climate Conference was twofold: to clarify the rules for the implementation of the Paris Agreement and to place the international community face to face with its responsibilities. COP22 took place in a climate of uncertainty, created by the election of Donald Trump at the White House.
Mortality increase due to heat waves has been extensively studied. For example, it is estimated that 70,000 additional deaths occurred during 2003 heatwave in Europe. The increasing frequency and intensity of heatwaves projected for the coming century is an important health concern.
Air ionization is known for decades, as is the correlation between negative ions and air quality: the more negative ions in the air, the less polluting particles. In urban environment, and especially inside buildings, negative ions are missing. To assess the nocivity of this lack of negative ions, scientists have studied the influence of air ionization on our physiology. Here are some picks from their research results.
