Air pollution is one of the most pressing environmental issues in Bangladesh, with the country frequently ranking among the most polluted in the world. [3] According to the World Air Quality Report, Bangladesh was the country with the worst air quality in 2020, a situation that has persisted over several years. [4]
Mold is a dangerous library pest because of the damage it causes to the collections. Mold thrives off of paper and books; these objects provide the fungi a source of nutrition, namely the sugar and starches present in the cellulose materials. [6] Mold feeds on cloth, leather, glues, adhesives, cellulose starch and starches in the sizing.
Prevention of mold exposure from food is generally to consume food that has no mold growths on it. [48] Also, mold growth in the first place can be prevented by the same concept of mold growth, assessment, and remediation that prevents air exposure. Also, it is especially useful to clean the inside of the refrigerator and to ensure dishcloths ...
Bangladesh Environment Conservation Act (BECA) is set of laws enacted by the government of Bangladesh in 1995 to conserve the nation's environment. [1] Its main goals were to "provide for conservation of the environment, improvement of environmental standards and control and mitigation of environmental pollution."(Bangladesh Environmental Conservation Act, 1995).
Air quality monitors are operated by citizens, [3] [4] [5] regulatory agencies, [6] [7] non-governmental organisations [8] and researchers [9] to investigate air quality and the effects of air pollution. Interpretation of ambient air monitoring data often involves a consideration of the spatial and temporal representativeness [10] of the data ...
Modern particulate samplers use a volumetric flow control system that pulls air through the particle separator at the velocity required to achieve the desired cutpoint. For air pollution applications, the definition of "particulate" does not include uncombined water , and water from a particulate sample must be removed before it is weighed.
The air sampler pump draws in air and deposits microscopic airborne particles on a culture medium. The medium is cultured in a laboratory and the fungal genus and species are determined by visual microscopic observation. Laboratory results also quantify fungal growth by way of a spore count for comparison among samples.
