toxic element
Dangerous chemical component
A toxic element is a chemical element harmful to living organisms, even in small amounts.
Lead, mercury, arsenic, and cadmium are classic examples—they accumulate in tissues and disrupt biological processes.
The term appears in environmental science, toxicology, and public health contexts: The soil was tested for toxic elements before construction began.
