Blyholdig

Blyholdig is an adjectival term used in Norwegian, Swedish, and Danish to describe substances or materials that contain lead (chemical symbol Pb). In scientific, industrial, and regulatory contexts, blyholdig materials are contrasted with blyfri (lead-free) materials.

Etymology: The word derives from bly, the word for lead, and holdig, meaning containing or bearing. The construction is typical for adjectives indicating content.

Usage: Blyholdig materials include pigments and solders, lead glass or crystal, lead-based alloys, and certain types of batteries. The term can refer to both intentionally formulated lead-containing materials and products that contain lead as an impurity.

Health and regulation: Lead exposure is a recognized health risk, particularly for children and during pregnancy. Many jurisdictions restrict the use of blyholdig materials or require labeling, safe handling practices, and proper disposal of lead-containing products, with recycling programs for such components.
