Tendo em conta o princípio dos 3R, modelos respiratórios como alternativas para estudos animais estão evoluindo. Especialmente para a avaliação dos riscos das substâncias respiratórias, há uma falta de ensaios adequados. Aqui, descrevemos o uso de fatias de pulmão humano de precisão de corte para a avaliação de substâncias no ar.
