Bly är ett metalliskt grundämne. Som metall är bly beständigt mot luft och syror. Bly och alla dess föreningar har en tendens att lagras i människokroppen och kan genom blyförgiftning orsaka fosterskador, njurskador och bestående skador på det centrala nervsystemet. Vid temperatur över 600 °C är blyets ångtryck större än 1 mbar vilket ger en mycket giftig blyånga. Bly skärmar av mot joniserande strålning och är särskilt effektiv mot röntgenstrålning. Därför är väggar och tak i röntgenrum klädda med bly. På latin heter bly plumbum, därav den kemiska beteckningen Pb.'
