Deposition of aero-pollutants as a source for pollution of surface storages for water supply
1997
Ristic, R. | Kadovic, R. (Sumarski fakultet, Beograd (Yugoslavia))
Products of wet and dry deposition of aero-pollutants, reached by over-boundary or internal-boundary transport, are significant source of pollution, almost, whole territory of Serbia (Yugoslavia). Products of wet and dry deposition endangere surface storages in two ways: (1) directly, by deposition on surface storages; (2) indirectly, by deposition on surface of catchment areas, and further transporting through hydrographic system. In the period 1992-1996 investigations were carried out at some localities in Serbia (Yugoslavia). Their results show that recorded quantities significantly over pass MDK (maximal permitted quantity). Investigations included analysis of samples of precipitation (rain and snow), soil and sediment from hydrographic system.

L'evaluation des risques pour la sante et l'environnement lies a differents types d'exposition tels que la pollution de l'air, necessite d'elargir les activites de surveillance de l'environnement. En milieu urbain, le trafic automobile devient la principale source d'emission de polluants entrainant dans les periodes de fort ensoleillement l'elevation des niveaux l'ozone qui peuvent quelquefois depasser les valeurs reglementaires. Il est donc important de connaitre sa distribution au niveau d'une agglomeration. L'utilisation d'un bioindicateur vegetal, le tabac Bel-W3, particulierement sensible a l'ozone, a permis d'etudier et de realiser la cartographie des differents niveaux d'ozone en juin, juillet et aout 1996 sur la Communaute Urbaine du Grand Nancy. En juin, periode caracteristique d'ensoleillement prolonge accompagnee d'un trafic urbain dense, l'etude cartographique montre une repartition concentrique autour du noyau urbain. La presence d'ozone la plus elevee se rencontre a la peripherie de l'agglomeration, particulierement au nord-est de Nancy-ville, ou le panache de pollution de la ville se deplace sous l'influence des vents dominants, et a l'ouest ou le relief accentue favorise l'accumulation de polluants.
