LEBS is the Portuguese acronym for “Limites de exposição baseados em saúde (LEBS)” (Limits of exposure based on health), otherwise known as relatorios pde, which is essentially the same as an HBEL (health-based exposure limit) such as ADE, or PDE. Often, in ANVISA regulations, they use the term synonymously with HBEL, ADE, and PDE
