Workers exposed to welding fumes may be at increased risk of damage to the same brain area harmed by Parkinson's disease, according to a new study by researchers at Washington University School of Medicine in St. Louis.Fumes produced by welding contain manganese, an element that scientists have linked to neurological problems including Parkinson's disease-like symptoms."In the United States alone, there are more than 1 million workers who perform welding as a part of their jobs," says Brad...

New research suggests that workers exposed to welding fumes may be at risk for developing brain damage in an area of the brain also affected in Parkinson's disease. The study is published in the April 6, 2011, online issue of Neurology®, the medical journal of the American Academy of Neurology. Fumes produced by welding contain manganese. Manganese is a chemical element that, even at low levels, has been linked to neurologic problems, including Parkinson's disease-like...

Central Pennsylvania lands, once dotted with iron furnaces, retain traces of earlier burning Iron furnaces that once dotted central Pennsylvania may have left a legacy of manganese-enriched soils, according to findings reported last week in the journal Environmental Science & Technology (ES&T). This manganese can be toxic to trees, especially sugar maples and other vegetation, say geoscientists funded by the National Science Foundation (NSF). The research, which quantified the amounts...

Iron furnaces that once dotted central Pennsylvania may have left a legacy of manganese enriched soils, according to Penn State geoscientists. This manganese can be toxic to trees, especially sugar maples, and other vegetation. The research, which quantified the amounts of manganese in soil core samples, was part of work done at the Shale Hills Critical Zone Observatory funded by the National Science Foundation. "Our group's focus was to study the soil chemistry," said Elizabeth M. Herndon,...

Sensitive new quantitive methods could be used to detect small signs of increased tremor and impaired motor skills caused by exposure to certain metals, and to follow up the treatment of neurological disorders, reveals a thesis from the University of Gothenburg, Sweden. "The aim was to investigate whether quantitative measurement methods, in other words sensitive computer-based methods, could be used to detect small changes in tremor or other motor functions resulting from exposure to low...

(Ivanhoe Newswire) -- Ever heard the saying: you are what you eat? Now, Canadian researchers may be saying: you are what you drink. They found children who drink water with more manganese have lower IQs. Researchers examined 362 children who lived in Quebec and were between ages 6 and 13. These kids all lived in homes that were supplied by groundwater. Investigators measured the concentration of manganese, iron, copper, lead, zinc, arsenic, magnesium and calcium in their tap water. Manganese...

Aluminum (or aluminium) is a soft, lightweight, silvery metal. It is an element in the boron group on the periodic table of elements, with the symbol Al and atomic number 13. On the earth's crust, aluminum is the most abundant metal, and the third most abundant of all elements on the earth's crust, after oxygen and silicon. It accounts for 8% of the weight of the Earth's solid surface. Because aluminum is a highly reactive metal, it doesn't occur in nature in a pure form. Aluminum forms a...

Manganese is a chemical element in the periodic table that has the symbol Mn and atomic number 25. Notable characteristics Manganese is a gray-white metal, resembling iron. It is a hard metal and is very brittle, fusible with difficulty, but easily oxidized. Manganese metal is ferromagnetic only after special treatment. The most common oxidation states of manganese are +2, +3, +4, +6 and +7, though oxidation states from +1 to +7 are observed. Mn2+ often competes with Mg2+ in...
