Arsenic is a naturally occurring element that can be found in soil, water, air, and many types of rocks. It is also used in a number of industrial processes, including the production of pesticides, wood preservatives, and semiconductors. Arsenic exposure can occur through ingestion, inhalation, or skin contact. Chronic exposure to arsenic has been linked to skin lesions, cancer, and other serious health problems. To protect oneself from exposure to arsenic, it is important to be aware of potential sources of contamination and to take steps to reduce exposure, such as using protective equipment and following proper hygiene practices.
