Mercury poisoning is a type of metal poisoning due to exposure to mercury. [3] Symptoms depend upon the type, dose, method, and duration of exposure. [3] [4] They may include muscle weakness, poor coordination, numbness in the hands and feet, skin rashes, anxiety, memory problems, trouble speaking, trouble hearing, or trouble seeing. [1]
The Reinsch test is an initial indicator to detect the presence of one or more of the following heavy metals in a biological sample, and is often used by toxicologists where poisoning by such metals is suspected. The method, which is sensitive to antimony, arsenic, bismuth, selenium, thallium and mercury, was discovered by Hugo Reinsch in 1841. [1]
A 1977 report by a Health and Welfare Canada's Task Force on Organic Mercury in the Environment that was formed in 1972, submitted a report that said that found that "despite elevated mercury levels, the clinical tests performed on six locals showed no acute or chronic effects of methyl-mercury poisoning." [31] [32]
Erethism, [n 1] also known as erethismus mercurialis, mad hatter disease, or mad hatter syndrome, is a neurological disorder which affects the whole central nervous system, as well as a symptom complex, derived from mercury poisoning.
At this point, tests proved that she had severe mercury poisoning. [5] [6] [9] Her blood and urinary mercury content were measured at 4,000 μg/L [7] and 234 μg/L, respectively—both many times their respective toxic thresholds of 200 μg/L and 50 μg/L (blood and urine reference ranges are 1 to 8 μg/L and 1 to 5 μg/L). [8]
Other nutrients such as thiamine deficiency at the general population demonstrates an aggravation of the mercury exposure symptoms. Similar to thiamine, iron aggravates mercury exposure effect while ascorbic acid will help reduce the mercury toxicity effect. Fat is another agent that participates in the reduction of the mercury toxicity.
