The composition and acidity of precipitation in Hungary
Atmospheric Environment (1967), 1984The aim of this paper is to summarize the results of precipitation chemistry measurements carried out in Hungary by using bulk and wet-only collectors. While data gained by bulk collectors show a west to east gradient in the concentration of different constituents, results obtained with a network consisting of wet-only gauges indicate a rather uniform ...

Precipitation: Its Acidic Nature
Science, 1975A comparison of the free hydrogen ion concentration and the total hydrogen ion concentration of rain samples shows that rain is a weak acid. The weak acid nature of rain casts doubt on the concepts that the acidity of rain is increasing and that these increases are due to strong acids such as sulfuric acid.

Fractional Precipitation of Nucleic Acid
Nature, 1954MELVILLE et al.1 have recently used turbidity measurements to follow the fractional precipitation of high polymers from solution. The turbid suspensions were found to be stable if very dilute polymer solutions were used. Nucleic acids are precipitated from aqueous solution by acids, cationic detergents, positively charged polyelectrolytes and alcohol ...

Water, Air, and Soil Pollution, 1976
The total annual emissions of sulfur oxides and nitrogen oxides in Canada are estimated to be 7.2 × 106 t and 1.4 × 106 t, respectively. These figures represent 5% and 2%, respectively, of the estimated worldwide anthropogenic emissions. Nearly two-thirds of the Canadian SO2 emissions come from primary smelters located in low population areas.

Acidic Precipitation Research in France
1990Some cases of forest decline were known 10 or 20 years ago in certain regions of France, mainly in the vicinity of industrial cities, but also as a consequence of the severe drought of 1976. But, beginning in 1983, forest decline, with the same symptoms as observed in Germany, become visible in the Vosges and was noticed in the following years in the ...

1990
Serious interest in chemical pollution in precipitation began in Japan in 1930. However, the strong influence of the surrounding oceans on the atmospheric pollution environment in this island country was not at first fully realized. In the 1970s, people in the Kanto Plains—Tokyo and the surrounding coastal plain area—experienced a period of severe eye ...

The effects of acid precipitation on amphibians
Ecotoxicology, 1993: A large number of studies conclusively demonstrate that low pH conditions have important ecological effects on amphibian communities. These effects vary developmentally and depend on complex interactions with other physical, chemical, and biological parameters. Acid sensitivity varies widely within and among species of amphibians.

Acid precipitation in historical perspective
Environmental Science & Technology, 1982The history of acid precipitation is traced from the first awareness of the problem in the mid-17th century to the present. An outline of the National Acid Precipitation Assessment program is also given, and the author makes recommendations for future research. (JMT)

Acid precipitation in The Netherlands
Environmental Science & Technology, 1978There is a pronounced relationship between SO/sub 2/ emissions and the acidification of precipitation in the Netherlands. However no such relationship can be demonstrated for NO/sub x/ emissions and acidification, probably because more than 40% of NO/sub x/ will be absorbed by the direct surroundings.The remaining 60% will hardly play a role in ...
