“…For B. cuvieri, on Teles Pires River in a preserved area (Castilhos et al, 2012), and on Rio Roosevelt belonging to Madeira River basin (Dos Anjos et al, 2016) in an area with deforestation and golddigging, studies showed higher concentrations of mercury compared to data from present study ( Table 6). There are studies showing higher mercury concentrations than present study for H. armatus with its counterpart Hydrolycus scomberoides in Tocantis River in an area with gold-digging and deforestation (Milhomem-Filho et al, 2016), in Tapajós River in an area with golddigging, deforestation and agriculture (Bidone et al, 1997), on Teles Pires River in an area with gold-digging and deforestation (Uryu et al, 2001). However, other studies have lower concentrations of mercury than those in present study for H. armatus, in Teles Pires River in an area with deforestation, gold-digging, and agriculture (Matos, 2018) and in a preserved area (Castilhos et al, 2012; Table 6).…”

“…Among mercury forms that are present in aquatic environments, methylmercury (MeHg) incites greatest interest from an ecotoxicological perspective, since it is a neurotoxin and has a tendency to bioaccumulate and biomagnify in trophic chains (Bisinoti and Jardim, 2004). Fish intake is considered the main pathway to human exposure from MeHg, particularly for riverside populations as fish is their main source of protein (Milhomem-Filho et al, 2016). To this end, analysis of fish muscle is a powerful tool to determine risk of mercury transfer to humans who feed on fish.…”

Ingestion of fish is considered the main pathway of human exposure to methylmercury (MeHg), particularly for riverside populations, where fish is the main source of protein. The objective of this study was to estimate concentration of MeHg based on total concentration of mercury in muscles of three species of carnivorous fish: Boulengerella cuvieri (bicuda), Serrasalmus rhombeus (piranha), and Hydrolycus armatus (cachorra), collected from Teles Pires River, Brazil. Furthermore, we calculated human health risk related to MeHg contamination caused by fish consumption. Fish were collected in 20 field campaigns from December 2011 to September 2016 at Teles Pires River, in area of influence of Colíder hydroelectric plant. Risk index (RI) related to ingestion of MeHg through fish intake was calculated considering that MeHg corresponds to around 90% of mercury in fish. There were no significant differences in average mercury concentration between all species: S. rhombeus (0.304 mg/kg–1), H. armatus (0.229 mg/kg–1), and B. cuvieri (0.199 mg/kg–1). RI calculated for sensitive groups (lactating women, breastfeeding infants and children) and RI calculated for general population presented average values, suggesting adverse health effects. This first assessment on MeHg and human exposure to people from Teles Pires River area through fish consumption suggests that mercury concentrations might be posing health adverse effects on people of this sensitive group. Further studies involving more fish specimens and considering fish biological factors are needed to fully understand health risks of mercury exposure to humans in this region.

“…Os sintomas neurológicos são retardo mental, convulsões e atraso no desenvolvimento (KASPER et al, 2007;WHO, 1990). Em gestantes, o excesso de consumo de peixes contaminados por Hg acima dos limites de segurança pode dificultar o desenvolvimento neurológico do feto (SILVEIRA et al, 2004;WHO, 1990). Milhomem Filho et al (2016 avaliaram as concentrações de mercúrio em famílias de pescadores no Maranhão.…”

Essa pesquisa consiste em uma revisão integrativa visando discutir sobre a concentração de mercúrio presente em peixes da região Nordeste do Brasil e identificar suas implicações na saúde. A revisão foi composta por seis etapas distintas: 1) elaboração a pergunta norteadora; 2) busca ou amostragem na literatura; 3) coleta de dados; 4) análise crítica dos estudos incluídos; 5) discussão dos resultados e 6) apresentação da revisão integrativa. A leitura dos títulos e resumos foi realizada de forma independente por dois revisores nas bases de dados Scientific Electronic Library Online (SciELO), Portal de Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), ScienceDirect e buscador Google Acadêmico. A coleta de dados foi realizada entre Abril e Agosto de 2018, incluindo os termos mercúrio, peixe, concentração, Nordeste e Brasil para a busca. Selecionou-se seis estudos observacionais. Os maiores níveis de Mercúrio (Hg) foram encontrados nas espécies S. cavalla (444,8 ± 519,9 ng/g-1), R. porosus (509 ng/g-1) e G. cirratum (500 ± 330 ng/g-1). Em quatro estudos incluídos nesta revisão verificou-se a concentração de Hg em peixes e sua relação com o comprimento e o peso. Concluiu-se que os peixes da região nordeste do Brasil apresentam, em média, concentrações totais de mercúrio abaixo do limite considerado seguro para consumo estabelecido pelas normas do Mercosul.

“…Mercury (Hg) in the Amazon region has been recognized since the 1980s, when gold mining had its activities intensified (1)(2) . Several studies (3)(4) also point out that disordered use and occupation of Amazonian soil, in addition to deforestation and fires, has contributed to the release of Hg to aquatic ecosystems.…”

Prevalence and factors associated with mercury exposure in riverside communities in the Brazilian Western Amazon

et al. 2020

View full text Add to dashboard Cite

Objective: to verify mercury exposure prevalence and identify its possible associated factors in two riverside communities in the Madeira River basin of the Western Brazilian Amazon. Method: a cross-sectional study comprising 95 children and adolescents. Age cycle, school attendance, Bolsa Família, number of siblings, meals, fish consumption, height by age were measured. Binary logistic regression was used to verify relationships between mercury exposure and its possible associated factors. Results: the general prevalence of mercury exposure was 46.3%; children, 35.4%; and adolescents, 57.4%. Associated factors were fish consumption (aOR=1.84; 95%CI 1.56-2.16), age cycle (aOR=2.50; 95%CI 1.09-5.7), parasites (aOR=1.22; 95%CI 1.02-2.71), and short stature (aOR=1.32; 95%CI 1.05-2.02). Conclusion: mercury exposure prevalence in riverside children and adolescents was considered worrying, with association with fish consumption, adolescence, parasites, and short stature.
