The second study concluded that air pollution was harmful for people with failing hearts. The research looked at 35 studies with data on thousands of heart patients in 12 countries, including the U.K., the U.S. and China. While air pollution has been linked to heart attacks, the new research now ties it to heart failure - a potential consequence of heart attacks.
The study assessed the link between daily increases in pollutants with increased heart failure, including hospitalization and heart failure mortality. It particularly focused on the effects of exposure to carbon monoxide, sulphur dioxide, nitrogen dioxide, ozone, and PM2.5 and PM10 particulate pollution.
The review found that people with already weakened hearts, who are exposed to high levels of carbon monoxide, nitrogen dioxide and fine particulate air pollution from vehicular exhaust fumes, are more susceptible to heart failure. These pollutants are particularly harmful, as they tend to penetrate the lungs deeply and enter the bloodstream.
City filters for urban pollution Densely populated urban environments have a higher level of air pollution, and to "keep the city out" in urban centres, Camfil has developed the "City" series of molecular filters - City-Flo XL™, CityCarb™, City-Flo™ and CitySorb™ - which represent the ultimate filtration solution for maintaining high indoor air quality control in public and commercial buildings.
Camfil's City filters are ideal for the ventilation systems of buildings situated along streets and roads with heavy traffic. These filters combine a high-performance particle filter and highly effective broad-spectrum carbon filter in a single filter product. The filters are highly effective against particulates, exhaust fumes and smells, and their highly activated carbon removes a wide range of volatile organic compounds and even ozone.
City filters have high energy-efficiency and ozone-removal ratings. In addition to their high filtration efficiency to remove harmful particles and gases, City filters offer additional benefits for building owners, as they require no modifications to air handling units for installation.
