Airborne sawdust and sawdust accumulations present a number of health and safety hazards. [9] Wood dust becomes a potential health problem when, for example, the wood particles, from processes such as sanding, become airborne and are inhaled. Wood dust is a known human carcinogen.
Uncommonly, sawdust exposure can come from sweeping dust off of old furniture, which may haw sawdust particles inside. Occupations at higher risk include carpenters, construction workers, shipbuilding workers, cleaning or maintenance staff (sawdust generation or reintroduction), and workers in logging, sawmills, furniture, and cabinet making.

Air pollution can cause diseases, allergies, and even death; it can also cause harm to animals and crops and damage the natural environment (for example, climate change, ozone depletion or habitat degradation) or built environment (for example, acid rain). [3] Air pollution can occur naturally or be caused by human activities. [4]
The solubility of gas obeys Henry's law, that is, the amount of a dissolved gas in a liquid is proportional to its partial pressure. Therefore, placing a solution under reduced pressure makes the dissolved gas less soluble. Sonication and stirring under reduced pressure can usually enhance the efficiency.
Dust kicked up by vehicles traveling on roads is a significant source of harmful air pollution. [8] Road dust consists of deposits of vehicle and industrial exhaust gas, particles from tire and brake wear, dust from paved roads or potholes, and dust from construction sites.
Soot, particularly diesel exhaust pollution, accounts for over one-quarter of the total hazardous pollution in the air. [ 12 ] [ 22 ] Among these diesel emission components, particulate matter has been a serious concern for human health due to its direct and broad impact on the respiratory organs.
Trichodesmium, also called sea sawdust, is a genus of filamentous cyanobacteria. They are found in nutrient poor tropical and subtropical ocean waters (particularly around Australia and in the Red Sea , where they were first described by Captain Cook ).
Particulates or atmospheric particulate matter (see below for other names) are microscopic particles of solid or liquid matter suspended in the air.The term aerosol refers to the particulate/air mixture, as opposed to the particulate matter alone, [1] though it is sometimes defined as a subset of aerosol terminology.
