But scientists have discovered one small population of people living in a remote part of the Andes in north west Argentina who have developed some resistance to arsenic. They have found that over thousands of years the local inhabitants there have developed a genetic ability to metabolise the arsenic to reduce the impact it has on their bodies. Local women in San Antonio de los Cobres in the Andes pictutred above carry a genetic variant that gives them greater tolerance of the poison arsenic by helping them to metabolise the element more efficiently.
Worldwide arsenic poisoning caused by contaminated water and food is thought to harm more than million people. Even low levels of arsenic poisoning can cause damage to the lungs, heart, kidneys and liver, leading to cancer, heart disease and diabetes.
The Emperor was said to have died from stomach cancer.

Based on the description, scientists put forward other theories as to why he died - which included arsenic poisoning.
