Five Reasons to Measure Black Carbon

Five Reasons to Measure Black Carbon

If we would need to sum up the main reasons why Black Carbon needs to be measured, these would be 5 most important ones.

  1. Black Carbon is a primary aerosol component of Diesel Particulate Matter, a known toxin and regulated pollutant by several regulatory agencies, including the California Air Resources Board (CARB).
  2. Diesel Particulate Matter is known to cause adverse health effects in people who are exposed, including premature hospitalization, asthma attacks, bronchitis, other respiratory and cardiovascular symptoms, and premature death.
  3. Black Carbon is the second leading cause of Global Warming.
  4. Black Carbon is emitted as a primary pollutant to the atmosphere through a variety of incomplete combustion of sources and fuels; BC concentration cannot be modeled or predicted, it must be measured.
  5. Black Carbon is NOT adequately characterized through PM-2.5 mass only measurements, chemical speciation is necessary.

Magee Scientific is the originator of the Aethalometer®, the most-widely-used instrument for the real-time measurement of Black Carbon aerosol particles in the atmosphere. We measure it, so you can take action. More about Aethalometer®

Heating Rate of Light Absorbing Aerosols

Heating Rate of Light Absorbing Aerosols

Scientific paper published in Environmental Science & Technology journal presents a novel methodology for experimental quantification of heating rate induced by light absorbing aerosols (LAA) (Black Crabon – BC and Brown Carbon – BrC) into an atmospheric layer.

Multiwavelength aerosol absorption measurements, performed by the Aethalometer, were coupled with spectral measurements of the direct, diffuse and surface reflected radiation to obtain highly time-resolved measurements of heating rate apportioned in the context of LAA species (BC, BrC, dust), sources (fossil fuel, biomass burning), and as a function of cloudiness.

One year of continuous and time-resolved measurements of heating rate were performed in the Po Valley, which allowed experimental determination of its seasonal behavior and daily cycle.

EXPOSURE TO BLACK CARBON DURING CYCLING

EXPOSURE TO BLACK CARBON DURING CYCLING

In the 2017 winter-spring period we performed static and mobile measurements of Black Carbon using our Aethalometers at different sites and cycling routes in Celje, Slovenia.
The results show that street intersections along the cycling routes influence the cyclists’ exposure to Black Carbon and should be as few as possible when planning cycling routes in urban areas.
Exposure can be greatly reduced by moving the cycling route away from busy roads, hence we proposed an alternative route and show that traffic planning and management should include all modes of transport.

HAIFA MUNICIPALITY IS ESTABLISHING ISRAEL’S FIRST EVER LOW EMISSION ZONE

HAIFA MUNICIPALITY IS ESTABLISHING ISRAEL’S FIRST EVER LOW EMISSION ZONE

Haifa is becoming the first city in Israel to establish a low-emissions zone – an important part of the national plan to reduce air pollution from all sources, including vehicles.Exposure to air pollution in Israel causes 2,220 premature deaths every year, half of them from transportation. We are happy the project focuses on Black Carbon using Aethalometer AE33 and its local/regional impacts, and that Haifa has also decided to monitor air pollution through this unregulated parameter.

STORY ABOUT ONE OF OUR INSTALLATIONS

STORY ABOUT ONE OF OUR INSTALLATIONS

Our instruments are installed on all continents, in more than 70 countries. This is one of our numerous installations.

Scientist Armando Retama installed an AE33 Aethalometer and a CO2 probe at a monitoring station operated by Mexico City half-way up the slopes of the volcano Popocatepetl. Below the station, the megacity (population ~ 30 Million) fills the Valle de Mexico with a dense layer of air pollution. During the day, atmospheric advection brings the combined cloud of pollution up the slopes of the surrounding mountains. The ratio between ‘Aerosol Carbon’ and CO2 provides an overall measure of the net aggregated emissions from the entire city.
