Frészpor

Frészpor is a term primarily used in Hungary to describe a very fine dust or powder that can accumulate in various environments. It is often associated with construction sites, workshops, or any location where materials are processed or broken down into small particles. The composition of frészpor can vary widely depending on its source, ranging from wood dust and plaster to metal filings and other fine debris.

The term is generally considered informal and descriptive rather than a precise scientific classification. In practical terms, frészpor can be a nuisance, requiring frequent cleaning to maintain hygiene and prevent respiratory irritation. In some industrial settings, specific types of frészpor, such as fine mineral dust, can pose health hazards if inhaled over prolonged periods, necessitating protective measures like dust masks and ventilation systems. The term itself is thought to derive from a colloquial or dialectal origin, emphasizing the extremely small size of the particles.
