Changes in Iron and Manganese Concentrations in

To determine how leachate recirculation affects the iron and manganese concentrations, the author utilized visual and statistical methods. The iron and manganese data for the three C&DD landfill sites, A, B, and C, were plotted on time series graphs and statistically tested for trends using Sen’s Slope/Mann-Kendall and Linear regression methods.

2001-7-9  Tukey analyses indicated that concentrations of iron and manganese were higher in water from the metasedimentary group Ms than in the other metasedimentary groups. To test if arsenic concentrations are related to iron or manganese concentrations in the data set, Spearman’s rank-correlation coefficients were

Background: Iron, manganese, and aluminum are three abundant metals on earth and their concentrations have increased in aquatic environments as a result of natural and industrial activities. This study was undertaken to report the median acute toxicity (LC50) and accumulation of the sub-lethal concentration (10% 96-h LC50) of iron (Fe),

2011-6-20  The iron and manganese concentrations at Site 2 were found to increase significantly with depth, as indicated in Figure 5(a) and 5(b). During the strongest stratification period (between March and July), the total iron and manganese in the bottom water increased to the highest concentration of approximately 13 mg/L and 0.11 mg/L.

Manganese- and Iron-Dependent Marine Methane

Anaerobic methanotrophs help regulate Earth’s climate and may have been an important part of the microbial ecosystem on the early Earth. The anaerobic oxidation of methane (AOM) is often thought of as a sulfate-dependent process, despite the fact that other electron acceptors are more energetically favorable. Here, we show that microorganisms from marine methane-seep sediment in the Eel

Drinking Water: Iron and Manganese

2016-5-6  Manganese can be objectionable in water even when present in smaller concentrations than iron. Iron will cause reddish-brown staining of laundry, porcelain, dishes, utensils, and even glassware. Manganese acts in a similar way but causes a brownish-black stain.

Targeting Iron & Manganese in Drinking Water WWD

2020-10-19  The regulations call for dissolved iron in treated drinking water to be maintained at or below 0.3 mg/L, and dissolved manganese to be maintained at or below 0.05 mg/L. Above these threshold concentrations, iron and manganese can turn drinking water rusty, create stains in laundry, and cause discoloration of porcelain sinks and tubs.
