“…The variables VBP18, VBP19 and VBP20 presented normality 5% of likelihood with the Kolmogorov-Smirnov test, disregarding the disparate points. This scenario of regional agricultural development is corroborated by the results of research by Krelling et al (2023). Figure 2 shows the boxplot chart of the variables under study.…”

Os modelos lineares mistos longitudinais são importantes por analisarem medições em frequências repetidas na evolução média no tempo. Neste trabalho foi realizada uma aplicação com modelos mistos longitudinais para investigar a relação entre o valor bruto da produção agropecuária expresso em reais associado às variáveis agropecuárias: quantidade de aves produzidas por cabeça, quantidade de suínos produzida por cabeça, quantidade de bovinos produzida por cabeça e produção de leite em mil litros produzida por municípios para os anos de 2018, 2019 e 2020 no estado do Paraná-Brasil. Os resultados mostraram que há um relacionamento entre a variável de interesse e as variáveis quantidades de aves produzidas por cabeça, quantidade de suínos e quantidade de bovino nos municípios que compõem o estado do Paraná estudada neste trabalho, e sendo possível identificar mesorregiões com as variáveis que explicam o valor bruto da produção agropecuária distintos para o modelo. Na análise de variância com os modelos, a variável produção de leite não foi significativa para explicar o valor bruto da produção agropecuária em cada ano, já as demais variáveis foram significativas ao nível de 5% de probabilidades. O modelo linear misto longitudinal forneceu informações necessárias sobre o relacionamento associado aos pesos que cada variável agropecuária forneceu no valor bruto da produção agropecuária que foi analisado no cenário econômico do estado do Paraná-Brasil.

“…The fact that plastic biomedia had not been reported in our study area before June 2023, despite previous (Moreira et al, 2016;Bettim et al, 2021;Mesquita, 2022;Krelling et al, 2023; Figure S1) and ongoing marine debris investigations, suggests that its presence in the Paraná coastline and, consequently, environmental input is most likely recent. Our research group performed a marine debris investigation field campaign that sampled Praia de Leste, Shangri-lá, and Pontal do Sul beaches in mid-May 2023, and these particles were not observed on that occasion.…”

“…At the lab, we identified the material as plastic biomedia and counted 411 items. It is worth noting that, despite different marine debris studies being conducted in this area (Krelling et al, 2017(Krelling et al, , 2023Bettim et al, 2021;Nunes et al, 2021;Mesquita, 2022), the presence of plastic biomedia, classified as mesoplastic (plastic items in the 5 -25 mm size fraction), was not reported before. Therefore, we decided to investigate this issue further to elucidate the possible sources of these particles on the Paraná coastline.…”

Plastic biomedia, also known as filter media, are small, perforated plastic pieces (polyethylene [PE] or high-density polyethylene [HDPE]) used as bacterial biofilm carriers to improve the wastewater treatment process, invented in Norway in the 1980s (Ødegarrd et al., 1994;Ballerini et al., 2022). These plastic particles, also called biocarriers, are applied in the Moving Bed Biofilm Reactor (MBBR) technology, the most used technique in wastewater treatment plants (WWTP) worldwide (Madan et al., 2022). This includes but is not limited to urban, industrial, and aquaculture wastewater treatment (Maurya et al., 2023). Although recognized by their We present the first report of plastic biomedia contamination on Brazilian beaches based on evidence collected from 14 beaches of the Paraná state coastline (southern Brazil). Plastic biomedia, also called biocarriers, are small, perforated plastic pieces used worldwide in wastewater treatment plants (WWTP) that apply the Moving Bed Biofilm Reactor (MBBR) process. Accidental release of these particles into the environment adds to Ocean's long-term plastic pollution problem. A high amount of plastic biomedia presence in the coastal areas of Paraná was first noticed by a community member, who found 411 plastic particles on a beach located in Pontal do Paraná, bringing this issue to our attention. In this study, plastic biomedia was retrieved from drift line alongshore transects (0.3 to 1 km long) and cross-shore transects (5 m wide) from the water line to the backshore zone. A total of 749 items were collected from 11 of the 14 sampled beaches, including the Mel and Superagui Islands nature reserves. The decreasing trend in plastic biomedia abundance with the increase in distance of the PEC southern outlet suggests that these particles probably originate from a WWTP in the Paranaguá Estuarine Complex (PEC). Once in the water, these floating plastic particles that followed the suspended sediment transport pattern were exported to coastal waters and were transported by longshore currents. Highlighting the potential role of the PEC as a substantial vector for marine debris to the Paraná coastline. The most likely source of this novel plastic contaminant to the Brazilian coastline are WWTP with MBBR systems. Therefore, stakeholders need to discuss and establish a reporting system so that plastic biomedia spillovers or losses are reported, and its dispersal in the environment is reduced.
