Question

how will absorbing aerosol particles in the boundary layer affect air pollution buildup and cloud formation only if the effects of the aerosol particles on atmospheric stability are considered

Answer 1

Answer:

Features: as solid particles so tiny drops of liquid fragments as small , which may have different chemical composition are included . One can distinguish primary particles emitted directly into the atmosphere , and secondary , resulting from reactions that occur in it . The concentration of particles in air is expressed in mg or ug of particles per m3 of air.

Sources: about 80 % of the particles in the atmosphere have -aerosoles marine natural product of crashing waves , dust entrainment by wind , volcanic eruptions , fires , pollen , etc. ; the major anthropogenic sources are combustion processes and losses in extractive and industrial processes , mainly mining, quarrying , cement , waste treatment , etc. It is also important quantitatively the formation of secondary aerosols from primary gaseous pollutants.

Evolution in the atmosphere: the particles become deposited in two ways :

• Dry deposition , sedimentation , affecting about 20 % of atmospheric particulate.
• Wet deposition , by stripping of the particles by rainwater; Additional particulate may promote condensation of the water , thereby causing precipitation.

Effects vary :

• The particle size: the diameter can range from less than one micron and about one millimeter .
• Composition: metal , both in atomic state and salts , mainly aluminum and calcium , but also to a lesser extent , currently lead by reducing their use in paints and gasolinas- and iron ; other salts , especially sulfates and nitrates ; and organic compounds , both naturally occurring and oils -terpenos essentials as -hidrocarburos- anthropogenic.
