演講題目 Topic: Viewing the Earth's Atmospheric Environment and Human Health from the
Perspective of Interstellar Aerosol
演講摘要 Summary:
Environmental problems extrude from place to place and time to time. The problems consist
of nearby in addition to international problems. The know-how of problems is important to
discover solutions. Air pollutants problems have been modified over a duration of time. Issues
like atmospheric brown clouds, weather extrude, unsafe air pollutants, black/muddy snow
that is hardly ever mentioned few many years lower back have now gained significance. This
bankruptcy elaborates the most important problems because of air pollutants.
Since bad air first-class influences human fitness withinside the brief and lengthy-term, a
great deal of study has been achieved on indoor and outdoor aerosol publicity; however,
there's a loss of unique records at the publicity and health dangers of inhalable aerosols that
contain bioaerosol in one-of-a-kind environments of human life.
Air pollutants can be described as any atmospheric situation wherein positive materials are
found in such concentrations that they could produce unwanted outcomes on the people and
their environment. These materials consist of gases (SOx, NOx, CO, HCs, etc) particulate
matter (smoke, dust, fumes, aerosols) radioactive substances, and lots of others. Most of
those materials are evidently gift withinside the surroundings in low (background)
concentrations and are normally taken into consideration to be harmless. Air pollutants are
a problem of apparent significance in a maximum of the sector that influences human, plant,
and animal health. For example, there is ideal proof that the health of 900 million city humans
suffers daily due to excessive levels of ambient air sulfur dioxide concentrations.
心得 Review:
Air pollutants are a totally complex physical and chemical system. It may be the notion of a
lot of elements that can be dissolved or suspended in air, a lot of which have interaction with
any other, and a lot of which acts collectively to supply their effects. The elements of air
pollutants extrude with the season, with business activity, with modifications in traffic, and
with the prevailing winds, to call only a few applicable factors. The composition of air
pollutants is, therefore, now no longer constant from daily or maybe a week to week on an
average, however developments to cycle. Average levels cross up and down fairly continually
relying on the time of year however the real stages are especially variable from three hundred
and sixty-five days to the next. One of the riskiest modes of transmission of fitness-associated
problems is, air serves as a vehicle. Therefore negative airflow of air and overcrowding
situations are developing an extra favorable situation to the transmission of pollutants.
At that time, some students had been involved that air transmission turned into too difficult
to prevent, and if you want to inspire human beings to clean their hands often and be aware
of hygiene, they intentionally downplayed the significance of air transmission. Wang Jiazhen,
associate professor of the Department of Chemistry at Chung Shan University and director of
the Aerosol Center, stated that aerosol now no longer best remains withinside the air longer
than the takeoff foam, it may ultimate for numerous hours, and it may unfold farther than
the current norm of 1 to 2 meters social distance. Once inhaled into the body, small debris of
virus aerosol, particularly the ones under 5 microns, can at once move the nasopharynx and
higher breathing tract, attaining the micro bronchus or even alveoli withinside the deeper
part of the lung, as opposed to being struck by the cutting-edge Detected by nasopharyngeal
sampling screening.
