Altogether 10… 20 kg/ha·a N from precipitation are introduced into the soil. The fertilization of the agriculturally used area increased from 50 to 120 kg/ha·a N between 1950 and 1982. The nitrogen concentration is theoretically increased by 0.4 mg/l due to infiltration of surface water and...
The oxidative conversion of strongly alkaline sulphide concentrations in wastewaters from the wet molybdenite enrichment is successfully performed within a relatively short time by the application of atmospheric oxygen, “Winkler adsorbent” (activated form of ash from Winkler generators) or...
About 53 million tons of liquid manure from the animal husbandry plants of the GDR are used for purposes of organic fertilization per year. Fertilization by liquid manure must be reasonably done, since there should be avoided fertilization and yield losses of agriculture and damages to the...
Some heavy metal concentrations were determined for the water and sediments within‐ the Altenwörth impoundment. The dissolved heavy metal concentrations were very low. The heavy metal contents in the sandy riverine sediments 10 or more kilometres distant from the dam wall were also at a low...
Selected journals are scrutinized for the period from 1980 to 1986 with respect to the application of HPLC to the detection of organic substances in water and the state of knowledge deducible from that is represented. Various chromatographic methods are compared with respect to their sensitivity...
