Total dissolvable manganese (TDMn) was measured at 13 stations in the East China Sea and the Yellow Sea. High manganese concentrations of more than 100 nmol/l were observed at stations near the Yangtze River estuary and in the bottom water of the central Yellow Sea, while the manganese conce...
Lots of lead in the water? Maybe manganese is to blameIn the right environment, a harmless mineral can do a lot to change the composition of the drinking water that flows through lead pipes. New research discovers how.F.J.RuizL.Ripoll...
The elevated concentrations are attributed to the diagenetic release of dissolved manganese from the underlying fine-grained sediments and its subsequent precipitation in the water column. The rate of manganese precipitation is rapid compared to the rates of diffusion and mixing in the bottom water. ...
drop of 1%, 2% and 5% in Performance IQ scores. Methods Data from two studies conducted in Canada were pooled resulting in a sample of 630 children (ages 5.9–13.7 years) with data on tap water manganese concentration and cognition, as well as confounders. We used the Bayesian Bench...
The "Zakrzówek" quarry is located in the south-western suburb of Cracow, about 600-900 m to the east of the Vistula riverbed. Exploitation of the Upper Jurassic limestone reached about 30 m below the static water level. Flooding process was started in 1992 after the mine abandoning and fi...

When rainwater filters through the soil and rocks, many things get dissolved in it such as small quantity of iron and manganese. This water, when sips through bed of rocks, becomes groundwater. Iron and manganese concentration can change drastically as t
Manganese, a group VII element of the periodic table, plays an important role in biological systems and exists in a variety of oxidation states. The normal level of Mn in air surrounding major industrial sites is 0.03 μg/m3, in drinking water 0.05 mg/liter and in soil between 560 and 85...
