Absorption of arsenic through the skin is minimal and thus, for example, washing hands or clothes and bathing in water containing arsenic or working in paddy fields with arsenic-contaminated waters do not pose risks to human health. Mitigation strategies should therefore focus primarily on reducing consumption of arsenic-rich drinking-water. 3.

Abstract. Metalloids such as boron and silicon are key elements for plant growth and crop productivity. However, toxic metalloids such as arsenic are increasing in the environment due to inputs from natural sources and human activities. These hazardous metalloids can cause serious health risks to humans and animals if they enter the food …
