Is catalyst harmful to humans

Catalysts themselves are generally not harmful to humans, as they are substances that speed up chemical reactions without being consumed in the process. However, some catalytic processes may involve toxic materials or produce harmful byproducts, which can pose health risks. Additionally, exposure to certain catalysts, especially in industrial settings, may lead to safety concerns if proper handling and safety protocols are not followed. Overall, the safety of catalysts depends on their specific chemical nature and the context in which they are used.
