“…However, we emphasize that since the categorization as "positive," "neutral," or "negative" was made a posteriori by the authors, these results reveal a broad and simplified view of what is considered as a perception of improvement (i.e., positive) or loss (i.e., negative) in the environment. Similar observations are reported by Silvano and Begossi [22], who found that although fishermen knew about mercury contamination in fishery resources, they continued to consume this resource. As well as some residents noticing negative changes in the environment due to mining, 85% of residents said they know about the contamination of the mined areas; however, they still collect and use plant species from these areas.…”

Background: Mining activities have environmental impacts due to sediment movement and contamination of areas and may also pose risks to people's food security. In Brazil, the majority of coal mining activities are in the south, in the Santa Catarina carboniferous region. In this region, previously mined areas contaminated with heavy metals frequently occur nearby inhabited zones. Mining is part of the daily lives of local communities, and its environmental impacts are visible in the landscape; however, plants with medicinal and food use from these areas can be still consumed. Heavy metals are contaminants that do not have odor, color, or taste, and are therefore difficult to detect. We aimed to verify whether people use plants from contaminated mine areas, and understand which factors can influence the use of these resources, even from areas visibly impacted. Methods: We conducted 195 semi-structured interviews with residents from 14 areas nearby abandoned mines in the main municipalities of the Santa Catarina carboniferous region. We asked each interviewee about the length of time they lived in the region, their perception of the quality of the environment, and what plant species were used and for what purpose. We constructed generalized multivariate linear models to verify which variables can affect the group of species mentioned and generalized linear models to verify which variables can affect the total number of citations. We estimated the frequency of citing species collected using the Smith index. Results: From all interviewees, 127 (65%) reported collecting plants for medicinal and food use, directly from contaminated mine areas. Long-term residents, as well as those who noticed more environmental changes (positive and negative), cited more plants used and had more detailed knowledge of plant use in their communities. When asked if they were aware of the possible contamination of mined areas, 85% said they knew about it. However, only 10% associated negative health effects with the use of plant species collected in contaminated mined areas.

“…In Brazil, contamination of soil, plant, and fishery resources also poses a health risk to local communities [21,22]. Coal mining in Brazil began in the late nineteenth century, and today, practically all coal produced in Brazil is mined in the southern area [23,24].…”

“…It is important to note that information is lacking for important target species and consumed species from both the coastal and continental waters of Brazil [9,10]. Another area in which the fishers can help is the monitoring of contaminants: as the study by Silvano and Begossi [44] shows, observations of bioaccumulation, such as the mercury content in fish muscle, can be made by fishers and can be very valuable.…”

21We followed landings of dusky grouper, Epinephelus marginatus, from 2013 to 2019. 22 We observed 1,896 individuals of dusky grouper, Epinephelus marginatus, in Copacabana, Rio 23 de Janeiro, from September 2013 to February 2019. The total weight of the catches was 6,065.57 24 kg, with an average of 1,442.50 kg/year and a std of 147.30 kg. 25 We integrated fishers in our study through citizen science (CS): individuals were trained 26 to monitor grouper gonads and supplied information on fishing spots and prices. After comparing 27 catch curves (based on weight) and curve prices (in the Brazilian monetary currency of reals), 28 our results showed that catches in the Copacabana fishery have been stable (the results of the 29 Kruskal-Wallis test showed no significant difference for either the weight of the catches or the 30 average prices of dusky groupers in the years compared). Copacabana has been a sustainable 31 fishery when considering its catches of dusky grouper. This is a very important result for 32 conservation and management, considering the importance of small-scale fisheries in terms of 33 their low fishing efforts and their possible effects on vulnerable species, as well as their 34 ecological and economic importance in developing countries. Citizen science, alomng with local 35 ecological knowledge, helps integrate research and fisheries as well as researchers and fishers 36 and allows for larger sampling efforts and management training for fishers. 57 (e) SFFs lack infrastructure, often occur in remote areas and have low political 58 power. 59 60 Citizen science, local knowledge and the Copacabana fishery 61Disciplines occupy different niches, and ecology came to be a separate niche (as did 62 human ecology) in the postwar period, altering its identity from a soft to a hard science; 63 however, the field of ecology has never lost its links to the physical and social sciences [7]. The 64understanding of the complexities of fisheries management can help to re-establish the balance 65 between the physical and social sciences and conservation ecology by demonstrating that 66 scientific research could be aided in obtaining positive outcomes for fisheries management by 67 other forms of knowledge. 68Currently, local knowledge (LEK) is still under scrutiny with respect to its usefulness and 69 its acceptance in biological or fisheries science [8]. Here, we argue that LEK is very important 70 for data-poor countries; through knowledge from fishers (i.e., LEK) or the public (i.e., CS), we 71 can reduce the costs of time and money by increasing the efficiency of ecological data collection. 72Tropical countries, in particular, lack the infrastructure for data collection, and many have high 73 biodiversity with several species for which there is no knowledge at all. In Brazil, for example, 74 among the 65 marine species most often consumed by marine small-scale fisheries, 33% are 75 decreasing, and 54% have an unknown status [9]. In the freshwater fisheries of the Amazonian 5 76 rivers, among the 90...

“…Os bioensaios de toxicidade, em sua maioria, são realizados em regiões temperadas, utilizando-se espécies e condições experimentais representativas dessas regiões, resultando incongruências nos resultados, quando comparados às regiões tropicais. Desta forma, muitos autores recomendam a utilização de espécies nativas em testes ecotoxicológicos sob condições representativas de regiões tropicais (BUCH et al, 2017;GHOSE et al, 2014;HOWE;REICHELT-BRUSHETT;CLARK, 2014;MANSANO et al, 2018;ROCHA et al, 2018b;SILVANO;BEGOSSI, 2016 Além disso, conclui-se que os bioensaios ecotoxicológicos são uma importante ferramenta na complementação das análises de monitoramento de reatores, e que os invertebrados Chironomus sancticaroli, Allonais inaequalis e Daphnia magna apresentam sensibilidade aguda e crônica ao LAS padrão e às amostras do reator, e podem ser recomendados como organismos-teste em bioensaios de no monitoramento.…”
