Exposure to some of these metals, such as arsenic, occur near or in hazardous waste sites or areas with naturally high levels in soil, rocks and water, according to OSHA. Others, like chromium, are used explicitly in construction, and OSHA warns workers in welding, painting, cement and more can face occupational exposure.
High exposure to arsenic can cause death, while lower exposure for longer periods of time can cause discoloration of the skin and corns or warts. Metals like chromium are carcinogens, with long-lasting health term effects potentially rising from extended exposure.
