INTRODUCTION The prevalence of iron deficiency anemia (IDA) is high among infants younger than two years old, especially in disadvantaged populations. OBJECTIVE To study certain social and biological determinants associated with IDA in children aged 12 to 23.9 months old in Northeast Argentina in the 2004-2005 period. METHODOLOGY Cross-sectional design. Explanatory outcome measures were org...

Pit lakes in the Lausitz lignite mining district of Germany are diverse in size and morphometry. Many are extremely acidic with pH ≤ 3 and high in iron concentrations. Productivity in most of the mining lakes is generally low and they support only simple food webs; a few of the acidic lakes, with high nutrient concentrations, are highly productive. State planners hope to develop the lake region...

OBJECTIVES To assess nutritional iron status and anemia prevalence in children less than 5 years old at public daycare centers in the city of Recife, PE, Brazil. METHODS A cross-sectional study, with a systematic random sampling of 162 children aged 6 to 59 months. Nutritional iron status was assessed in terms of body iron reserves (serum ferritin), transferrinemia (serum iron, total iron bin...

Background: Barapukuria coal mine which has been operating from 2002 is situated in such a location that is dependent on agriculture. Pollution from Coal mining poses a huge risk to the ecosystem and surrounding soil. So, there could be some impact of the Barapukuria coal mine on the surrounding soil. The main aim of this study is to identify the soil quality of the study area and also see how ...

A legacy of coal mining in the Appalachians has provided a unique opportunity to study the ecological niches of iron-oxidizing microorganisms. Mine-impacted, anoxic groundwater with high dissolved-metal concentrations emerges at springs and seeps associated with iron oxide mounds and deposits. These deposits are colonized by iron-oxidizing microorganisms that in some cases efficiently remove mo...

Technical reclamation and spontaneous succession (passive restoration) are the two main approaches for restoring post-mining sites worldwide. Despite substantial differences between both approaches, little is known regarding how they differ in terms of ecological outcomes. We assessed compared vegetation structure composition one forest that 29 years old, technically reclaimed forests 2 10 old ...

abstract background iron overload is the main transfusion related side effects in patients with transfusion dependent hemoglobinopathies. severe iron deposition in tissues leads to organ dysfunction. many organs can be affected such as heart, liver, and endocrine organs. cardiac failure and liver fibrosis are the consequent of iron overload in transfusion dependent hemoglobinopathy. magnetic re...
