During 25–29 September, for example, the development of the pollution episode includes two distinct secondary aerosol formation processes.The occurrence of high concentrations of nano-sized particles during the clean period is characteristic of aerosol nucleation (Fig. New particle formation typically corresponds to a regional event, and a variety of compounds have been associated with aerosol nucleation, including sulfuric acid, organics, basic species, and preexisting particles (7, 19–23).levels in Beijing on the basis of measurements of ambient gases and aerosol properties. S1) may be affected by transport, local emissions, and chemistry, the evolutions of the particle size, mass, number concentration, chemical composition, and meteorological parameters (such as measured wind direction and speed and back-trajectories) were analyzed to decouple the various processes.The measured PM) demonstrate the presence of a higher number concentration of smaller particles during the clean period but a slightly lower particle number concentration of larger particles during the polluted period. 1During our observation period, southerly winds were most prevalent (50%), followed by winds from the northwest (42%) and northeast (7%) (Fig. The wind was much weaker from the south but stronger from the northwest and northeast.The formation mechanisms leading to severe haze episodes with exceedingly high PM in Beijing has been suggested to be mainly from industrial pollution and secondary inorganic aerosol formation, but negligibly from traffic emissions (14).In addition, meteorological conditions may govern regional and long-range transport of air pollutants (17, 18).crystalise, crystalize, crystallise, shed light on, sort out, crystallize, elucidate, illuminate, enlighten, straighten out, clear up, clear - make free from confusion or ambiguity; make clear; "Could you clarify these remarks?"; "Clear up the question of who is at fault"elaborate, expatiate, expound, lucubrate, dilate, flesh out, exposit, enlarge, expand - add details, as to an account or idea; clarify the meaning of and discourse in a learned way, usually in writing; "She elaborated on the main ideas in her dissertation"When I have intimated that the foreigner with the scar was a member of the Brotherhood (admitted in Italy after Pesca's departure from his native country), and when I have further added that the two cuts, in the form of a T, on the left arm of the dead man, signified the Italian word "Traditore," and showed that justice had been done by the Brotherhood on a traitor, I have contributed all that I know towards At the back of the estrade, and attached to a moveable partition dividing this schoolroom from another beyond, was a large tableau of wood painted black and varnished; a thick crayon of white chalk lay on my desk for the convenience of any grammatical or verbal obscurity which might occur in my lessons by writing it upon the tableau; a wet sponge appeared beside the chalk, to enable me to efface the marks when they had served the purpose intended.
Also, primary and secondary particles undergo chemical and physical transformations and are subjected to cloud processing and transport in the atmosphere (8, 9).Your access to the NCBI website at gov has been temporarily blocked due to a possible misuse/abuse situation involving your site.This is not an indication of a security issue such as a virus or attack.The stronger northwesterly and northeasterly winds were most frequent during the clean period, carrying unpolluted air masses from the less populated northern mountainous areas.Furthermore, precipitation typically occurred between the pollution episodes, and wet deposition was also responsible for removal of aerosols.
