Naturally occurring arsenic in the bedrock of the Northern Appalachian Mountain belt was first recognized in the late 19th century. The knowledge of the behavior of arsenic in groundwater in this region has lagged behind nearly a century, with the popular press reporting on local studies in the early 1980s, and most peer-reviewed research articles on regional patterns conducted and written in t...

Arsenic is an environmental hazard and the reduction of drinking water arsenic levels is under consideration. People are exposed to arsenic not only through drinking water but also through arsenic-contaminated air and food. Here we report the health effects of arsenic exposure from burning high arsenic-containing coal in Guizhou, China. Coal in this region has undergone mineralization and thus ...

BACKGROUND Millions of people in Bangladesh, India, Taiwan, and Chile are consuming high concentration of arsenic through drinking water, and thousands of them have already developed chronic arsenic poisoning. There is no specific treatment. Some authors suggest the use of vitamins and minerals for more than 6 months. The present placebo-controlled double-blind study was conducted to evaluate e...

Certain heavy metals such as mercury, lead, arsenic and cadmium are toxic even in reduced concentrations in blood. Their accumulation in the body causes serious illnesses. The most important heavy metals in human pathology are: mercury (Hg), cadmium (Cd), arsenic (As) and lead (Pb). The author mentions the heavy metal sources of poisoning, their toxicokinetics and toxicodynamics, clinical featu...

| February 2013 | 168 l e t t e r t O e d it O r These changes in depilator agents affected our patients’ mortality accordingly from 22% in 1998, to 5.7% in 2003,[4] and no mortality in 2009,[5] suggesting that elimination of arsenic from the depilators could change the outcomes dramatically. In this letter we would like to bring the attention of readers to this point that an arsenic base depil...

A major source of childhood lead poisoning, still a serious problem in the United States, is paint. The dangers of lead were known even in the 19th century, and the particular dangers to children were documented in the English-language literature as early as 1904. During the first decades of the 20th century, many other countries banned or restricted the use of lead paint for interior painting....

Doubt could be expressed that a special section on late 19th century mathematics, or, more specifically, on Victorian mathematics, was an appropriate place for a lecture on 19th century logic. Most 19th century scholars would have been of the opinion that philosophers are responsible for research on logic. On the other hand, the history of late 19th century logic indicates clearly a very dynami...

Introduction: Extensive hemolysis resulting in anuric renal failure is the main clinical sign of acute arsine poisoning. Plasmapheresis and exchange transfusion are recommended for patients with massive hemolysis. We report four cases of arsine exposure which demonstrate the effectiveness of continuous vein-venous hemodiafiltration and on-line hemodiafiltration for arsenic removal. Method: Bloo...
