In fact, the WHO published new sharpened air quality guidelines on the day before the webinar took place. There has been a visible ‘corona effect’ during the COVID-19 lockdown and the consequent reduction in the burning of fuels in industry and transport. Mean nitrogen dioxide levels in Madrid, Milan and Rome, for example, fell by about 45% from 2019 to April 2020; in Paris, it was 54%. This, however, is a shortterm and extraordinary effect, Bielfeldt said. Clearly pollution will return; the question is by how much. The major components of air pollution are: Toxic gases: sulfur dioxide, nitrogen oxides (NOx), volatile organic compounds (VOCs) & photochemically derived ozone Particulate matter (PM), mainly of <2.5 µm diameter that can reach the alveoli of the lungs. PM is also a carrier of organic compounds that can generate reactive oxygen species (ROS), as well as metals, notably copper, that catalyse the oxidation of lipids and proteins in exposed tissues. Indoor pollutants, such as smoke from indoor combustion of coal, wood and petrol, plus cigarette smoke, both of which generate toxic gases and PM. The main hazards to skin from air pollution comes from two sources: ROS, notably superoxide (O2), hydroxyl (OH), ozone (O3) singlet oxygen (1 O2) and hydrogen peroxide (H2O2), which form free radicals that can interact with many molecules in the human body; and particles loaded with VOCs and polycyclic aromatic hydrocarbons (PAHs).

[article]  inGLOBAL PERSONAL CARE > Vol. 23, N° 3 (03/2022) . - p. 16-18 Titre : Hand sanitisers for COVID protection and more Type de document : texte imprimé Auteurs : Andrew Warmington, Auteur Année de publication : 2022 Article en page(s) : p. 16-18 Langues : Anglais (eng) Catégories : Cosmétiques Désinfectants Mains -- Désinfection Mains -- Soins et hygiène Index. décimale : 668.5 Parfums et cosmétiques Résumé : The COVID-19 pandemic has caused a complete disruption of the supply chain, characterised by increasing raw material lead times and costs. The personal care sector was as vulnerable as any other. Traditional ways of working had to be adapted rapidly to meet the situation, including design work being done remotely and laboratory workers only going into the lab when absolutely necessary.
