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.
World Asthma Day is taking place today, May 3, with the theme « You can control your asthma. » This annual event is organized by the the Global Initiative for Asthma (GINA) to improve asthma awareness and care around the world.
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.
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?
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.
I spent 4 stimulating days at Indoor Air 2016 conference. This conference is a biennial event on research in the field of IAQ (indoor air quality) gathering most of the international community (labs, companies, public agencies, etc.).
This article is the first in our new series about air purification technologies. It concerns the air purifiers with HEPA filters efficiency.
Every day, we expose ourselves to natural and technological risks. Because it is better to be safe than sorry, we are careful. Are the precautions that we take appropriate?
Asthma is a common chronic non-communicable disease that affects as many as 334 million people of all ages in all parts of the world (Source : Global Asthma Report-2014).
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.
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.
Allergies affect up to 40% of the world's population, and the proportion of sufferers is on the rise. Symptoms are aggravated by air pollution.
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.
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.
This article in our series about air purification technologies concerns photocatalysis-based air purifiers. Do they keep their promises ?
The second article in our series about air purification technologies concerns the air purifiers with activated carbon filter. Discover the truth about them.
We spend most of our time indoors breathing polluted air. Cars do not protect their passengers from pollution. On the contrary, they prevent pollutants from evacuating. Do not underestimate the dangers you face.
An exposure to diesel engine emission significantly increases the risk of lung cancer. WHO (World Health Organization) has classified diesel engine exhaust emissions (DEEEs) as carcinogenic to humans.
Asthma strikes more and more people. Bad air quality, indoor or outdoor, is often a triggering or aggravating factor of asthma. An air purifier can help get some relief, and have good nights.
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.
