TITLE:

ASSESSMENT OF ENVIRONMENTAL IMPACTS CAUSED BY DISPOSAL OF EMERGING DRUGS IN WATER BODIES

KEY WORDS:

PAGES: 150
BIG AREA: Outra
AREA: Ciências Ambientais
SUMMARY:

Human interventions in recent decades have caused great destruction of natural habitats around the planet, resulting in profound changes in ecosystems, through contamination by heavy metals and toxic agents. In this context, water pollution from medicines can be one of the main threats related to the decline of several species of aquatic animals, including the group of amphibians. In this way, ecotoxicological studies are essential to detect and establish permissible limits of pollutants present in water, allowing preventive and corrective measures for the protection of fauna and flora. In addition, people's attitudes and behaviors over time have significantly worsened the pollution of water resources. The lack of awareness and knowledge on industrial and domestic waste management issues by the population, including pharmacists, as well as the effects they cause on human health and the environment can result in the problem worsening. In view of the above, the present work aimed to: (a) carry out a review of the literature on the impacts of drugs on the development and survival of amphibians; (b) to investigate the toxicological effects of the drug Carbamazepine (CBZ) using tadpoles of the species Physalaemus cuvieri (Leptodactylidae), as a bioindicator organism of environmental changes; (c) to analyze the knowledge about environmental risks and attitudes of undergraduate students of the Biological Sciences course at the Federal University of Rio Grande do Norte. As a methodology, the following were carried out: (a) a scientometric survey on the status of knowledge about the impacts of drugs on the development and survival of amphibians, through the analysis of articles; (b) assays with Physalaemus cuvieri tadpoles to assess mutagenicity; (c) an environmental risk perception study to understand how students perceive their actions to the environment. In the review, the lethal and sublethal effects caused by pharmaceutical compounds on amphibians, and the occurrence and permanence of these substances in the environment were discussed. The results of the trials are being analyzed and studied. Regarding the students' perception of environmental risk, most are aware that the actions are not correct and that they cause environmental problems, but they continue to dispose of them incorrectly. The justifications and positions of the students showed that they are aware of the risk, but do not relate the man exposed to these dangers. Ongoing efforts or programs of environmental education must be reinforced among students and the population. Creating guidelines for the safe disposal of medicines is a high priority. There are major challenges in the environmental conservation effort. It is critical that we develop an understanding of how factors associated with urbanization drive changes in biological systems, as well as create ways to monitor these effects in urban environments around the world.
