Arsenic was known to be poisonous during the Victorian era. [105] Beginning in about 3000 BC arsenic was mined and added to copper in the alloying of bronze, but the adverse health effects of working with arsenic led to it being abandoned when a viable alternative, tin, was discovered. [106]
The IDLH (immediately dangerous to life and health) value for arsenic metal and inorganic arsenic compounds is 5 mg/m 3 ... based on non-carcinogenic effects, ...
A dominant kind of metal toxicity is arsenic poisoning. This problem mainly arises from ground water that naturally contains high concentrations of arsenic. A 2007 study found that over 137 million people indicates that more than 70 countries may be affected by arsenic poisoning from drinking water.
Arsenic: When high amounts of arsenic is inhaled or ingested through coal ash waste, diseases such as bladder cancer, skin cancer, kidney cancer and lung cancer can develop. [ 5 ] [ 11 ] Ultimately, exposure of arsenic over a long period of time can cause mortality. [ 5 ]
The toxic effects of arsenic, mercury and lead were known to the ancients but methodical studies of the overall toxicity of heavy metals appear to date from only 1868. In that year, Wanklyn and Chapman speculated on the adverse effects of the heavy metals "arsenic, lead, copper, zinc, iron and manganese" in drinking water. They noted an ...
The incident occurred when arsenic was inadvertently added to dried milk via the use of an industrial grade monosodium phosphate additive. [2] This incident also led to negative health effects for thousands of other infants and individuals, which has had lingering health effects. [2] [3]
A 2007 study found that over 137 million people in more than 70 countries are probably affected by arsenic poisoning of drinking water. The problem became a serious health concern after mass poisoning of water in Bangladesh. [1] Arsenic contamination of ground water is found in many countries throughout the world, including the US.

Arsenical bronze is an alloy in which arsenic, as opposed to or in addition to tin or other constituent metals, is combined with copper to make bronze. The use of arsenic with copper, either as the secondary constituent or with another component such as tin, results in a stronger final product and better casting behavior. [1]
