wziewnych

Wziewnych is the genitive plural form of the Polish adjective wziewny, which means inhalable, breathable, or able to be inhaled. In scientific and regulatory contexts, wziewny describes substances or particles that can enter the respiratory system. The form wziewnych is used when referring to multiple inhalable items, for example in phrases such as pyłów wziewnych (inhalable dust) or cząstki wziewnych (inhalable particles).

In aerosol science and occupational hygiene, a key use is to distinguish the inhalable fraction from other size-based fractions. The inhalable fraction includes particles that can be drawn into the nose or mouth during breathing, whereas smaller fractions are characterized as respirable and capable of penetrating deeper into the lungs. The term wziewnych appears in standards, risk assessments, and exposure limits that focus on what can be inhaled by workers or by the general population.

Grammatical note: wziewnych is a case form of wziewny, not a standalone noun. It is employed to modify plural nouns in contexts requiring the genitive case, such as “pyłów wziewnych” or “cząstek wziewnych.” The base word wziewny is used more broadly to indicate inhalability in both everyday and technical Polish.
