Air quality and particles Epidemiological(流行病学) evidence associates atmospheric particles with diseases and mortality Particles penetrate the lungs, blocking and irritating aIr passages. Particles themselves could exert toxic effects. ( toxic substances present in the particles [polycyclic Aromatic Hydrocarbons are examples of toxic substances in aerosols.]
Air Buoyancy Akin to water keeping something afloat, samples can be “lifted” by air, artificially decreasing their apparent weight. This air buoyancy can have a significant effect on smaller samples. Electrostatic Forces Electrostatic charges are almost always present in any environment, particularly in areas with very low humidity. If there are

Air Safety: End of the Golden Age? First-World aviation has become so safe that a passenger who takes a domestic jet flight every day would on average go 36,000 years before succumbing to a fatal crash. But certain aerial dangers that were practically absent from the First World in the 1990s might be poised for a resurgence (Among these hazards are terrorism, mid-air collisions, and ground collisions. We explore recent data about the mortality risk of air travel, and discuss the prospects for the years ahead Arnold barnett
