Which health effect is NOT typically associated with nickel compounds?

Nickel compounds are known to cause a variety of health effects, particularly related to dermal and respiratory exposure. Contact dermatitis is a common effect due to nickel's allergenic properties, which typically manifest as skin rashes or irritation upon contact. Airway irritation can occur with inhalation of nickel dust or fumes, leading to respiratory symptoms.

Lung cancer is associated with prolonged exposure to certain nickel compounds, especially in occupational settings where workers might be exposed to dust, fumes, or other forms of nickel over an extended period.

Respiratory depression, on the other hand, is not a typical health effect linked to nickel exposure. It generally refers to a slowing of breathing or a decrease in oxygen intake, often associated with other types of toxins or drugs that act on the central nervous system. Nickel compounds influence skin and respiratory health but do not typically impact the central nervous system in a way that causes respiratory depression. Thus, it is not considered a health effect of nickel compounds.
