Sources3
- This dust, most often produced by natural sources, travels as far as Japan, Scandinavia, or the Amazon, where it plays an important role for the Earth's biology and climate. (zmescience.com)
- Particulates come from a variety sources, said Axel Friedrich, a Hong Kong-based international transport consultant. (acfa.org.sg)
- The main sources of this particulate matter are the industry standard cast iron brake disks and their friction partners, the brake pads. (laserlines.co.uk)
Mortality1
- Epidemiological studies have shown that lung disease, cardiovascular disease, and their mortality are associated with particulate matter. (ac.ir)
Organic2
- This sugar is used to build organic matter - in the trunk, roots, leaves, branches and flowers. (americanforests.org)
- Dust also sometimes contains organic molecules called ligands. (zmescience.com)
Indoor air qua1
- Why is indoor air quality important? (healthlinkbc.ca)
Processes1
- Saharan dust is mostly produced by natural processes -- for all the impact humans have on the planet, we seem to not play a very important role in this one. (zmescience.com)
Dirt1
- A specialized rotating brush is used to scratch and loosen dirt and dust from impervious surfaces, allowing the vacuum system to recover practically all particulate matter. (dot.gov)
Asthma1
- Knowing your area's air quality in real-time is important, especially for those who have heart and lung conditions, asthma, or allergies. (davisnet.com)
Include1
- Important features in histologic diagnosis include spongiosis (accumulation of fluid in the intercellular and intracellular areas) and exocytosis (infiltration of leukocytes through the epidermis). (medscape.com)
Measurements2
- However, heating engineers also come into contact with particulate matter and are required to be able to work with different measurements in this area. (testo.com)
- On-site particulate matter measurements are therefore part of your day-to-day work and serve to protect both the environment and people. (testo.com)
Typically1
- A continuous filtration system prevents very fine particulate matter from leaving the hopper, which prevents the formation of the dust trails typically seen with conventional mechanical sweepers. (dot.gov)
Harmful2
- The relative abundance of Cyanobacteria , which is harmful, increased during dust. (aaqr.org)
- Home furnishings can also release harmful chemicals and particulates. (pegasushomecare.com)
