The objective of this paper is to study the histological changes induced by Reldan 40EC in a dose of 0.01 ml chlorpyrifos/g body weight at the level of the lungs of the amphibian specimens Pelophylax ridibundus (Pallas, 1771). The insecticide was administrated by intraperitoneal injection (1 injection at 2 days in a scheme for 2 weeks). Highly degenerative changes were observed in animals cultured at 22–24°C, compared to those cultured at 4–6°C: thickness of alveolar septa, intraparietal, higher number of hypertrophied goblet cells, disorganization of blood capillaries, fibrosis.
