“…Within the last decade, the burial of bodies in cemeteries has aroused the interest of scientists, due to its polluting potential (Gonçalves et al 2022). According to Batista et al (2022), better planning is necessary regarding burial practices due to the risk of groundwater pollution from this type of activity. The risks pertaining to this type of pollution must be evaluated, as the degree of understanding with regard to the polluting loads of cemeteries remains insu cient (Franco et Rodrigues and Pacheco 2003).…”

“…The risks pertaining to this type of pollution must be evaluated, as the degree of understanding with regard to the polluting loads of cemeteries remains insu cient (Franco et Rodrigues and Pacheco 2003). These studies point to the need for better monitoring of cemetery areas and to assess, in detail, the toxic effects of by-products coming from cadaveric decomposition (Batista et al 2022).…”

“…Most necropolises were built without prior studies assessing the impacts on the environment and the local community (Neckel et al 2021). According to Gonçalves et al (2022), the increasing number of burials, especially during the SarsCov-2 pandemic, led to a worsening of the pollution scenario and to an alert about the potential ecotoxicological risks derived from the presence of necro-leachate in cemeteries (Gonçalves et al 2022).…”

Cemeteries are among the most polluting sources of groundwater and surface water in the world. Necroleachate, a liquid released during the putrefaction of corpses, is the main culprit of such pollution. Among the compounds in this liquid are the potentially toxic amines cadaverine and putrescine, which are still poorly understood in terms of the environmental health risks they pose. This study evaluated the acute toxicity of cadaverine and putrescine, using e cient contamination bioindicators of aquatic environments. Danio rerio and Daphnia magna were exposed to both amines individually or in a mixture. Acute toxicity (LC 50 ) was then observed in both organisms after exposure to the amines individually.Cadaverine showed higher lethality for D. magna (LC 50 -9.5 mg. L -1 ) and D. rerio (LC 50 -335.5 mg. L -1 ) than did putrescine (LC 50 -36.7 mg. L -1 and LC 50 -452.6 mg. L -1 , respectively). In embryotoxicity tests with D. rerio (hatching rate and malformations), delayed hatching, vertebral column malformations, and pericardial edema were observed after exposure to an amine mixture. However, co-exposure to cadaverine and putrescine was not toxic to D. magna. The results of this study con rmed the e ciency of the bioindicators used to assess contaminants in cemeteries and raised awareness of the toxic potential of cadaveric decomposition by-products.
