(SI) Aerosoli so trdni ali tekoče delci suspendirani v zraku oziroma atmosferi. Delci se v atmosfero emitirajo neposredno iz različnih virov (primarni delci), ali pa nastanejo v atmosferi preko različnih foto-kemijskih pretvorb (sekundarni delci). Prašni delci različnega izvora imajo različno kemijsko sestavo, obliko in različna fizikalna stanja. Aerosoli so vpleteni v številne procese v atmosferi – sodelujejo pri različnih kemijskih in fizikalnih pretvorbah atmosferi, nastanku kislih padavin, vplivajo na prosojnost in električne lastnosti atmosfere. Delci v ozračju pomembno vplivajo na klimo, vreme in tudi na zdravje ljudi. Različne epidemiološke študije so pokazale povezavo med povišanimi koncentracijami delcev PM10 in porastom bolezni respiratornega in kardiovaskularnega sistema. Manjši, ko so delci, globlje prodrejo v dihalne poti. Projekt izvaja meritve obstoječih obremenitev zraka na območju pristanišča, z metodami in na način, ki ureja monitoring kakovosti zunanjega zraka.
(EN) Aerosols are solid or liquid particles suspended in the air or atmosphere. Particles are emitted directly into the atmosphere from various sources (primary particles) or are formed in the atmosphere through various photochemical transformations (secondary particles). Dust particles of different origins have different chemical compositions, shapes, and physical states. Aerosols are involved in many processes in the atmosphere - they are involved in various chemical and physical transformations of the atmosphere, in the formation of acid precipitation, and in the transparency and electrical properties of the atmosphere. Particulate matter in the atmosphere has a significant impact on climate, weather, and human health. Various epidemiological studies have shown an association between elevated concentrations of PM10 and increases in respiratory and cardiovascular diseases. The smaller the particles, the deeper they penetrate the respiratory tract. The project measures the existing air pollution in the port area, using the methods and in the manner regulated by the ambient air quality monitoring. |
