It is often difficult to recover from an arsenic poisoning. Severe damage is done to many parts of the body. Treatment includes (according to the book Treatment of Acute Poisonings):
“1. Intensive supportive therapy
2. Treatment with dimercaprol should be initiated at once…; 4 mg/kg intramuscularly every four hours for 48 hours, followed by 3 mg/kg twice daily for eight days constitutes the maximum recommended dosage. These injections are painful and locally irritant. They should therefore be given in different sites successively.
3. Renal damage may be severe and require peritoneal dialysis or haemodialysis.
4. Liver damage may require conventional therapy, and where this fails exchange blood transfusion.” (Matthew and Lawson 1970)
If arsenic does not kill you outright, it causes cancer. The studies done in Taiwan were due to the epidemic of bladder cancer, believed to be caused by arsenic in the water. In C?rdoba, Argentina, it is the same: arsenic laden water and a high cancer rate. In fact, the cancer causes 23 percent of the deaths in the area. (Schroeder1974) A good test to detect the presence of even a minute amount of the element was developed by English chemist James Marsh. The test is named the Marsh test in honor of him. The sample to be tested is put into a hydrogen generator. If there is any arsenic in the substance, it would be converted to arsine (AsH3). Arsine then combines with the evolved hydrogen. Next, the hydrogen is heated as it moves through a glass tube, thus breaking up the arsine and the arsenic is left in the tube. The miniscule amounts still produce a considerable stain. (Bodin and Cheinisse 1970)
Conclusion
As more and more is learned about arsenic, the world becomes better prepared to deal with the problems caused by this element. It is one of the most common elements and is easily available. As it is right now, arsenic poses a serious threat to the lives of nearly all humans because of its toxicity and amount in the world. Several countries have already felt the damage caused by arsenic.
The poison travels easily in water and is present in much of the world’s groundwater, which is a large source of our drinking water. Arsenic has been shown to cause cancer and deaths. However, the element is obviously very ambiguous because in other studies it has been shown to have a healing effect. Any research done within the next few years would greatly add to our knowledge of the element and enable us to protect ourselves. The impending crisis in India would be a good opportunity to study the effects of the poison and perhaps show the rest of the world the importance of awareness and spur them into action. Arsenic is a deadly element that must be contained and regulated more strictly than it is now. As yet, few people know much about the effects of arsenic. This is unfortunate since it is an element that will most likely affect the lives of many people on this planet within the next few decades.
As said before, arsenic is a very ambiguous element. It has the both effect of curing diseases and causing them. In addition, its colorful history makes it a highly entertaining topic to study. With its impact on humankind and in the ecosystem, it also offers a ready problem for scientists to work on that will impact many lives. With more knowledge, the world will be able to use arsenic in the manners most beneficial to humankind.
