Alerted by the data in its possession, ANSES calls on the public authorities to continue efforts to reduce ambient air pollution and make some recommendations.
The National Agency for Food Safety, Environment, and Labor (ANSES)published Tuesday, July 16, the results of its expertise relating to ambient air particles. The public institution relied on results and scientific readings to determine, " with strong levels of evidence," the health effects caused by certain components of ambient air particles including carbon soot, organic carbon, and ultrafine particles. The
On the compounds and particle size of ambient air: the dangerous consequences of ultrafine particles and carbon soot
At the end of its expertise, with 160 published studies since the 2013 WHO Report on Evidence on Health Aspects of Air Pollution , and reviewing the scientific literature on the subject since that date, the agency attributes Soot carbon, organic carbon and ultrafine particles of nanometric size have the greatest adverse effect on health, with cardiovascular respiratory damage, as well as anticipated deaths .
Soot carbon and ultrafine particles would also have consequences on the child's development of cognitive performance. Soot carbon is another cause of low birth weight. ANSES retains all the same that the body of studies remains limited on this subject.
Finally, there is moderate evidence that secondary inorganic aerosols(which include ammonium, sulfate, and nitrate), transition metals (iron, zinc, nickel, copper, and vanadium), silica and endotoxins cause respiratory and cardiovascular problems and anticipated deaths.
Concerning the sources of ambient air particles: emissions from road traffic are really harmful
For ANSES, " the evidence of adverse health effects related to exposure to emissions from road traffic is strong ". Again, carbon soot, but also PM2.5 particles (whose diameter is less than 2.5 micrometers), road dust and Diesel exhaust particles reinforce the link with respiratory, cardiovascular and respiratory problems. anticipated deaths. The effects are more moderate on neurological health and perinatal health.
ANSES is able to confirm that emissions caused by road traffic, petroleum and biomass products, and coal combustion have health implications.
ANSES advocates for the reduction of road traffic and the development of cleaner automotive technologies
With these damning conclusions, the Agency calls on public authorities to adopt new policies concerning air by reducing ambient air pollution and by acting on the main sources of emissions, that humans have the capacity to control. ANSES evokes an essential reduction in road traffic, coal combustion, petroleum products, and biomass and the reduction of exposure to desert dust.
Regarding road traffic, the Agency believes that future developments in the automotive sector technologies "will allow a more or less marked reduction in ambient air pollution ", without solving the problems. The decrease in traffic should, therefore, be accompanied by a reduction in energy consumption and the development of mobility modes.
Finally, ANSES wishes to continue efforts to carry out research into the health effects of harmful particles from agriculture, shipping or airport activities, regretting the limited data currently available. available on these sections.
