Acidifying Emissions in The Netherlands

Water, Air, and Soil Pollution, 1995
The emission of acidifying compounds to air in the Netherlands, expressed as acidifying equivalents, consisted in 1992 mainly of NOX (45%), NH3 (35%) and SO2 (20%). Transportation, agriculture and large combustion plants each contributed about 30% to the national total emission of acidifying compounds.

ACIDIFIED MILKS

JAMA: The Journal of the American Medical Association, 1926
The recent literature on acidified milk in infant feeding has been repeatedly1reviewed in this journal, and therefore need not be summarized again. The modification of cow's milk by the addition of acid is based on the high content of buffer substances in cow's milk, the resistance of which must be broken down before gastric digestion can proceed ...

Evolution in an acidifying ocean

Trends in Ecology & Evolution, 2014
Ocean acidification poses a global threat to biodiversity, yet species might have the capacity to adapt through evolutionary change. Here we summarize tools available to determine species' capacity for evolutionary adaptation to future ocean change and review the progress made to date with respect to ocean acidification. We focus on two key approaches:

Anaerobic treatment of acidified and non‐acidified substrata in UASB reactors

Journal of Chemical Technology & Biotechnology, 1999
The selection of a suitable sludge which will be the inoculum of the reactor is the first step in the start-up procedure of an anaerobic reactor. The sludge selected (inoculum) for this study was obtained from a UASB (Up-flow Anaerobic Sludge Bed) reactor used for the treatment of alcohol industry wastewaters.

Deposition of Acidifying Compounds

1992
Inputs of acidifying compounds to terrestrial ecosystems include deposition of the gases NO 2 NO, HNO 2, HNO 3, PAN, NH 3, SO 2 and the ions NO 3-, NH4 +, SO4 2- and H + in precipitation, cloud droplets and particles. Recent research has identified particular ecosystems and regions in which terrestrial effects are closely linked with specific ...

Deposition of acidifying compounds in Sweden

Water, Air, & Soil Pollution, 1995
The Swedish Environmental Research Institute (IVL) has monitored deposition of acidifying compounds in Sweden. The monitoring programmes were initiated by various air quality protection associations, and regional forest and environmental authorities.

A classification of acidified catchments in Britain

Environmental Pollution, 1992
To compare catchments of possible acidified waters in Britain an extensive database was compiled for nearly 600 catchments of lakes and streams for which chemical data were available. Information on the database included map-derived data, pollutant deposition estimates and hydrological characteristics.

Decomposition of thiosulphate in acidified oxidants

Talanta, 1967
The Wollack procedure has been used to study the competition between oxidant and acid for the thiosulphate ion. In concentrated hydrochloric acid solutions of iodine, iodate and chloramine-T, polythionates are the chief products, whereas in acid permanganate substantial amounts of other products occur.

Effects of pH and temperature on heterotrophic bacteria in acidified and non‐acidified lochs

Journal of Applied Bacteriology, 1993
An investigation into the impact of acidification on bacterial populations in Scottish lochs revealed that in the range pH 3.8–6.5, increasing acidity had little effect on activities and diversities of aerobic heterotrophs. Only one organism, a Cytophaga species, showed reduced numbers at ...
