Resumo: | Microplastics are another type of contaminant of concern today, abundant in all ecosystems, have high potential for contamination, derived from larger plastics or for the right use, are produced on a large scale, because they are derived from materials with wide use, in addition to having low degradation capacity, they are discarded inappropriately causing problems for many organisms. Although amphibians can be subject to contamination, being exposed in both aquatic and terrestrial ecosystems, there are few studies on the ingestion of these contaminants. They are animals that are indicators of environmental health and the global population decline is caused by multiple stressors, such as habitat loss, temperature warming, parasites, herbicides, heavy metals and diseases. These environmental contaminants are important contributors to understanding the decline of the world population, as well as microplastics. This work aimed to report one more type of contaminant to the group of amphibians. 120 individuals of Leptodactylus macrosternum were collected in two areas in municipalities in Pernambuco. During March 26 to April 5, 2019 (rainy season) and September 17 to October 22, 2019 (dry season). Of the total number of individuals collected, almost 86% had microplastics in their stomach contents, totaling 449 particles. Ingestions occurred accidentally during the capture of food items. There was no significant difference between the areas studied and seasonality did not interfere with intake for this work. The types of materials and colors of the particles found in all collected samples were similar to the studies found in the literature for ingestion of other organisms, even aquatic, with blue fibers/filaments being the most representative. The need to combat these contaminants is urgent, we must have a radical change in our attitudes regarding the decrease in the use and proper disposal of plastic waste. |

Embora, os anfíbios possam ser alvo de contaminação, sendo expostos tanto em ecossistemas aquáticos como terrestres, existem poucos estudos sobre a ingestão desses contaminantes. Eles são animais indicadores da saúde ambiental e o declínio populacional global é causado por múltiplos estressores, como perda de habitat, aquecimento da temperatura, parasitas, herbicidas, metais pesados e doenças. Esses contaminantes ambientais são contribuintes importantes para entender o declínio da população mundial, assim como os microplásticos. Esse trabalho teve como objetivo relatar mais um tipo de contaminante para o grupo dos anfíbios. Foram coletados 120 indivíduos de Leptodactylus macrosternum em duas áreas em municípios pernambucanos. Durante os dias 26 de março a 05 de abril de 2019 (período chuvoso) e 17 de setembro a 22 de outubro de 2019 (período seco). Do total dos indivíduos coletados quase 86% apresentaram microplásticos em seu conteúdo estomacal, totalizando 449 partículas. As ingestões ocorreram de maneira acidental durante a captura de itens alimentares. Não houve diferença significativa entre as áreas estudadas e a sazonalidade não teve interferência na ingestão para esse trabalho. Os tipos de materiais e cores das partículas encontradas em todas as amostras coletadas foram similares aos trabalhos encontrados na literatura para ingestão de outros organismos mesmo aquáticos, sendo as fibras/filamentos azuis as mais representativas. A necessidade para combater esses contaminantes é urgente, devemos ter uma mudança radical nas nossas posturas quanto à diminuição da utilização e descarte adequados dos resíduos plásticos.Submitted by (ana.araujo@ufrpe.br) on 2023-08-24T14:23:23Z No. of bitstreams: 1 Thamires Freitas Campos.pdf: 1252001 bytes, checksum: 1b15adfa4ef1e5305ae8d346530b5a2a (MD5)Made available in DSpace on 2023-08-24T14:23:23Z (GMT).
