Wildfires and heatwaves, which generate microscopic airborne pollutants, risk undermining international efforts to improve air quality, protect human health and safeguard nature, the World Meteorological Organization (WMO) said on Monday.<\/p>\n
The United Nations\u2019 weather and climate agency underlined the links between air pollution and climate change, which scientists say is leading to more frequent and more intense heatwaves and wildfires.<\/p>\n
\u201cExtreme wildfires are increasing, leading to big health consequences because of the high toxicity of smoke,\u201d the WMO said in a statement accompanying its latest annual Air Quality and Climate Bulletin.<\/p>\n
<\/p>\n
\u201cWhilst regulations in Europe and North America have reduced industrial and transport PM2.5 emissions, exposure to fire-related PM2.5 has increased.\u201d<\/p>\n
Particulate matter PM2.5 is composed of microscopic particles and droplets of less than 2.5 micrometres in diameter, which is a health hazard because it can penetrate deep into the lungs and bloodstream.<\/p>\n
It is emitted by fossil fuel-driven industrial activities, farming, domestic heating and transport, as well as by wildfires and dust storms.<\/p>\n
The report said the world needs to better monitor air pollutants such as aerosol \u2014 including black carbon and microplastics \u2013, fine particles and ground-level ozone.<\/p>\n
These pollutants \u201care not sufficiently monitored even though they are widespread and are potentially harmful to ecosystems\u201d, the WMO said.<\/p>\n
\u201c(We need) complementary and coordinated policies on air quality and climate because they cannot be dealt with in isolation.\u201d<\/p>\n
\u201cAir quality and climate change can\u2019t be dealt with separately. If one worsens, the other does too,\u201d Lorenzo Labrador, from the WMO\u2019s Global Atmosphere Watch network of scientists, told AFP.<\/p>\n
\u201cIn places where there are relatively powerful forest fires, we find a lot of fine particle pollution,\u201d he said.<\/p>\n
Microparticles generated by burning vegetation are \u201cmuch more toxic\u201d than those emitted by other sources, even car exhaust, he stressed.<\/p>\n
They damage the health of people and wildlife living far from the fire itself because they are carried by the wind, but their poisonous effect is not sufficiently taken into account in air quality assessments, Labrador said.<\/p>\n
\u201cConventional risks models based on total PM2.5 concentrations may underestimate wildfire-attributable mortality by up to 93 percent,\u201d the WMO said.<\/p>\n
One study cited in the WMO Bulletin says extreme fire-smoke events have tripled globally since the 1990s, contributing to nearly 100,000 additional deaths per year between 2010 and 2018, although this may be an underestimate.<\/p>\n
Another source of air pollution that carries major health risks is ground-level ozone, which accumulates when temperatures rise, atmospheric conditions stagnate and solar radiation is intense, as seen during recent heatwaves in China, Europe and the southeastern United States.<\/p>\n
\u201cThis increased exposure to ozone pollution has the potential to lead to tens of thousands of additional premature deaths,\u201d particularly due to respiratory diseases, the WMO warned.<\/p>\n
Another growing concern is aerosol particles, which can also travel to oceans and continents far from their source.<\/p>\n
They can alter the way the atmosphere reflects sunlight, change the chemical properties of land and water, and pollute otherwise clean environments.<\/p>\n
\u201cOne example is the deposition of black carbon \u2014 or soot \u2014 on snow and ice, which reduces the amount of sunlight reflected by these surfaces and in turn can hasten the melting process,\u201d the WMO explained.<\/p>\n
Another example is microplastics, formed when plastics break down because of sunlight or other factors, and found virtually everywhere \u2014 in the air, the soil and the oceans.<\/p>\n
One simulation in the WMO Bulletin estimates there are \u201c51 million tonnes for land and 22 million tonnes for the ocean \u2014 which are in turn a source of microplastics for the atmosphere\u201d.<\/p>\n
\u201cAs plastic production and, critically, mismanaged plastic waste, continues to increase,\u201d monitoring the airborne paths that carry microplastics from their source and dump them in remote environments will be \u201ccrucial\u201d, the report said.<\/p>\n<\/p><\/div>\n
