Palladium in Waste Waters and Surface Waters of North Rhine-Westfalia

Specific electric conductivity of water samples in a polluted urban stream was compared with other water quality parameters such as concentration of inorganic carbon, total organic carbon, and total nitrogen. Increasing of water conductivity 1.3...10 times was observed downstream canalization outlets discharging drainage waters together with residential waste waters from inhabited district of city. In some periods water conductivity showed good correlation with pollutants concentration such as TN and IC (with correlation coefficients 0.54...0.96). The received data show that electric conductivity can be used for revealing waste waters pollution in fresh surface waters.

Rapid Deterioration

Finland's water resources are abundant and can be considered adequate to meet needs except in some coastal areas. This abundance was previously considered so obvious that water resources were used carelessly, without a thought to the harmful changes in water quality caused by the reckless use of lakes e.g. for discharging waste waters. In the late 1950's people finally perceived the rapid deterioration of Finland's beautiful lakes. An administration for water pollution control was established and a new Water Act was passed at the beginning of the 1960's. Since then the fight for clean waters has continued with varying success. What is the state of Finnish surface waters now, and what are the prospects for the future?

Some spectrometric and extraction photometric methods for the determination of uranium were compared using pure solutions, a model sample and samples of surface waters and waste waters; the characteristics examined included sensitivity, accuracy, repeatability, time demands and tediousness. Among the most sensitive methods are those based on the use of triphenylmethane dyes in the presence of surfactants; uranium is separated from associate ions by extraction into tri-n-octylamine in an organic solvent and subsequently re-extracted into an aqueous phase. The results compare well with those attained by using methods given in the Czechoslovak State Standard and in the standard of the Czechoslovak Uranium Industry corporation.

AbstractThe genus Klebsiella is seemingly ubiquitous in terms of its habitat associations. Klebsiella is a common opportunistic pathogen for humans and other animals, as well as being resident or transient flora (particularly in the gastrointestinal tract). Other habitats include sewage, drinking water, soils, surface waters, industrial effluents, and vegetation. Until recently, almost all these Klebsiella have been identified as one species, ie, K. pneumoniae. However, phenotypic and genotypic studies have shown that “K. pneumoniae” actually consists of at least four species, all with distinct characteristics and habitats. General habitat associations of Klebsiella species are as follows: K. pneumoniae—humans, animals, sewage, and polluted waters and soils; K. oxytoca—frequent association with most habitats; K. terrigena— unpolluted surface waters and soils, drinking water, and vegetation; K. planticola—sewage, polluted surface waters, soils, and vegetation; and K. ozaenae/K. rhinoscleromatis—infrequently detected (primarily with humans).

Toxic Trace Metals

INTRODUCTION“Acid rain” and “acid deposition” are terms no longer confined to the lexicon of atmospheric scientists and 1imnologists. Public awareness of and concern over this phenomenon, particularly as it affects acid-sensitive regions of North America, have increased dramatically in the last five years. Temperate ecosystems are suffering from decreased pH caused by acid deposition. Human health may be directly affected by respirable sulfates and by the increased solubility of toxic trace metals in acidified waters. Even man's monuments are deteriorating as airborne acids etch metal and stone features.Sulfates account for about two thirds of airborne acids with wet and dry deposition contributing equally to acids reaching surface waters or ground. The industrial Midwest is widely assumed to be the source of most sulfates reaching the acid-sensitive Northeast since S02 emitted as a byproduct of coal combustion in the Midwest dwarfs S02 emitted from all sources in the Northeast.
