This designated factor of Water, Air and Soil pollutants bargains unique contributions from BIOGEOMON, a global symposium on surroundings habit and the assessment of built-in tracking of small catchments, held in Prague, Czech Republic, in September 1993. The assembly attracted approximately two hundred scientists from 27 nations on 5 continents. BIOGEOMON was once a free continuation of one other overseas assembly, GEOMON, which was once held in Prague in 1987. either sym­ posia supplied a discussion board for the dialogue of rules on environmental difficulties in western and jap Europe, with very important contributions from the yank continent. With the dramatic cave in of the iron curtain, it was once our desire that extra so than GEOMON, BIOGEOMON would offer possibilities for the loose alternate of rules, fostering the improvement of study collaborations among its individuals. With foreign openness comes the expanding attention that each indus­ trialized state has its personal legacy of environmental degradation. Anthropogenic affects range in severity and scale; air and water delivery of pollution rework neighborhood affects into local and international ones, ignoring political obstacles and eco­ nomic alterations. Environmental outcomes of anthropogenic actions frequently are detectable on the surroundings point. hence, the problem of environment technological know-how, and to the people who perform it, is to increase a accomplished realizing of surroundings functionality some time past and at the moment, and to use such figuring out towards minimizing destiny insults to the neighborhood, nearby, and international environment.

Trends in atmospheric pollutant chemistry and openfieid precipitation Trends in the mean monthly concentrations of S02 and N02 in air, over the period 1987-1993, are presented in Figure 3. 1). However, S02 concentrations were highest during winter 1986-1987 and 1990-1991 compared to the rest of the period. , 1995; Laurila, 1990). 09). 149). This could be related to the present increase in N pollution in Europe (Granat, 1993; Matzner and Meiwes, 1994). No increasing trend in atmospheric N02 concentrations in the USA since the early 1960's is evident (Driscoll and Likens, 1993).
