The indoor air, where we all spend about 90% of our lives, is more polluted than the outdoor one. The same external pollutants are found there, moreover more concentrated due to the entrapment effect of the external air, essentially due to the absorbing action of walls, floors, furniture.
The pollutants of indoor environments are represented by house dust, by the materials with which the house and its furnishings are built, by the coatings. The study: Air pollution and indoor settings, published on the The World Allergy Organization journal, said: "Indoor environments contribute significantly to total human exposure to air pollutants, as people spend most of their time indoors.
Household air pollution (HAP) resulting from cooking with polluting ("dirty") fuels, which include coal, kerosene, and biomass (wood, charcoal, crop residues, and animal manure) is a global environmental health problem.
Indoor pollutants are gases, particulates, toxins, and microorganisms among others , that can have an impact especially on the health of children and adults through a combination of different mechanisms on oxidative stress and gene activation, epigenetic, cellular, and immunological systems.
Air pollution is a major risk factor and contributor to morbidity and mortality from major chronic diseases. Children are significantly affected by the impact of the environment due to biological immaturity, prenatal and postnatal lung developme nt.
Poor air quality has been related to an increased prevalence of clinical manifestations of allergic asthma and rhinitis. Health professionals should increase their role in managing the exposure of children and adults to air pollution with better methods of care, prevention, and collective action.
Interventions to reduce household pollutants may promote health and can be achieved with education, community, and health professional involvement."
Canada: temperatures up to 50 degrees still leave no respite
Canada set an extreme heat record for the third consecutive day: 49.5 degrees were recorded in Lytton, a village northeast of Vancouver, in the midst of a heat wave that would have caused more than 200 sudden deaths reported in recent days in the region.
"At 4:20 pm Lytton Station broke daily and historic temperature records once again," tweeted Environment and Climate Change Canada. The Royal Canadian Mounted Police has announced that at least 134 people have died since Friday in the metropolitan area located on the Canadian Pacific coast, in a grip of heat that is also affecting the country.
The feared fire alarm is triggered in the country with the first outbreaks. The residents of Lytton, the Canadian town that in recent days recorded the highest temperature in the history of the country (49.6 ° C) were forced to evacuate due to a fire. The record heatwave that hit British Columbia this week claimed 486 lives in just five days.
