Arsenic is also a common n-type dopant in semiconductor electronic devices, and a component of the III–V compound semiconductor gallium arsenide. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining with the ...
Some chemicals are linked to cardiovascular disease and reduced lung function. Other adverse health effects might arise from inhaling more mobile and toxic forms of arsenic, chromium and benzene. Exposure to magnetite, which can form when fire burns iron, has been linked to Alzheimer's disease, for example.
