It also has some worried that the fibers from fiberglass are just as dangerous as asbestos -- it's sometimes referred to negatively as "man-made asbestos" or the asbestos of the 20th century. But while early research on rats in the 1970s stated that "fibrous glass of small diameter is ...
Microplastics break even further into nanoplastics, which are small enough to move through human organs— including the brain — and enter our cells. Nearly everything around you — carpets, curtains, coasters, cups, packaging, clothing, couches, beds — contains plastic, and it all sheds plastic...
Our fear is that microplastics and nanoplastics might act in a similar way to deadly asbestos fibers. Like asbestos, they are not broken down in the body and can be taken up into cells, killing them and then being released to damage yet more cells. Reassuring, for now But there is a ne...
The researchers observed that when macrophages encountered these small and dangerous types of particles (including smaller asbestos fibers), the macrophages "activated" to recruit other immune cells to the site. However, because these longer particles are less able to be removed physically, activated m...
The simplest kind of filter is a sieve: something with holes that are big enough to trap some particles and small enough to let others through. Some vacuum cleaners do use filters like this to stop bigger particles of dust and dirt—but how do you catch smaller dirt particles as well?
Exposure to relatively small quantities of asbestos fibers, they concluded, was directly responsible for the development of cancers, asbestosis and related diseases. Taking into account evidence provided by economists and building industry management, however, the report assumed that despite the ...
A small amount or smudge or streaks can have an enormous impact to your windows rendering the windows look dirty and dull. Cleaning your windows is an essential daily chore that many people hate and are disinterested by it due to the fact that it’s, let’s face it, cleaning windows is...
Asbestos Program. Asbestos is a fibrous material used in some insulation and fireproofing. When the fibers become airborne and are inhaled, they can cause serious health problems. The EPA's Asbestos Program provides resources on how to identify and manage asbestos. As a governmental agency, the ...
If you encounter black or very dark asphalt floor tiles they are probably very high in asbestos fibers. We discuss floor tiles as an asbestos fiber source in buildings in more detailat ASBESTOS FLOOR TILE IDENTIFICATION.Cork Flooring Tiles as an Indicator of Building Age -...
8 The coated fibers are wound onto cylinders called bobbins. The bobbins are loaded into a spinning machine and the fibers are twisted into yarns of various sizes. Quality Control The very small size of carbon fibers does not allow visual inspection as a quality control method. Instead, produci...
