“…According to the literature, metals are accumulated and stored in bone structure with resultant loss of Ca levels (Hansson et al, 2020). The concentrations of Cd and Hg found in the muscle tissue of C. asellus were similar to those found by Da Silva Costa et al (2022) in the muscle tissue of the fish species Plagioscion squamosissimus (Cd ~ 0.05 µg/g and Hg ~ 0.31 µg/g), which was collected in the Araguari River middle section, also located in the State of Amapá.…”

Colomesus asellus (Amazonian Puffer) is endemic to the Amazon Basin. It uses channels and streams to reproduce, spawn and feed. In areas close to urban centers, these fish may be exposed to anthropogenic residues containing mixtures of metals that can be bioaccumulated, resulting in genetic alterations. Therefore, we aimed to determine the extent of nuclear alterations in erythrocytes of female C. asellus resulting from the bioaccumulation of metals in tissues and organs. Metal concentrations were analyzed by atomic absorption spectrophotometry. Tissue metal concentrations decreased in the following order: Fe > Zn > Cu > Mn > Hg > Pb > Ni > Cd > Cr. In fish tissues/organs, the concentration of metals followed, in decreasing order, liver > skin > gonads > musculature > bones. The most frequent nuclear alterations were nuclear invagination, nuclear budding and lobulated nucleus. Metal concentrations and resultant nuclear alterations observed can damage C. asellus, thus compromising the conservation of this species at the mouth of the Amazon River.

“…However, the concentration (p50) of Hg measured in our study was up to six times lower than that reported in the previously cited study. Furthermore, the results of our study were compared with studies conducted in the Brazilian Amazon, where gold mining is one of the main anthropogenic activities; Lino et al ( 2019 ) reported Hg values between 0.0006 mg/L and − 0.023 mg/L in Tapajós River Basin; Vieira et al ( 2018 ) reported Hg mean values of 0.0024 mg/L from the Rio Madeira Basin; Viana et al ( 2021 ) reported average Hg concentrations of 0.008 mg/L and da Silva Costa et al ( 2022 ) reported Hg values between 0.005 and 0.0085 mg/L in the Araguari River. While in the work developed by Meili et al ( 1991 ) on Hg concentrations in Poznań surface waters, values of 20 ± 8 ng/L (range 8–40) were denoted showing statistically significant differences between the mean Hg concentrations in the river water under study.…”

Illegal gold mining activities have contributed to the release and mobilization of Hg and environmental degradation in many parts of the world. This study aims to determine the concentration of Hg in five provinces of the Amazon Region of Ecuador, in addition to assessing the risk to human health of exposed populations, applying deterministic and probabilistic methods. For this purpose, 147 water samples were collected in rivers and streams crossing and/or located near mining areas. As a result, 100% of the samples analyzed exceeded the maximum permissible limit (MPL) according to the water quality criteria for the preservation of aquatic life of the Ecuadorian regulations, while 7% of the samples exceeded the MPL for drinking water. On the other hand, considering the European Environmental Quality Standard (EQS) for surface water bodies, in our study, 100% of the samples exceed the maximum permissible limit (0.07 µg/L), and with respect to the Canadian water quality guidelines, 35% of the samples exceed the permissible limit (0.001 mg/l) for drinking water, and 100% of the samples exceed the limit for life in water bodies (0.0001 mg/l). The risk assessment revealed that the probability of developing adverse health effects from exposure to Hg is below the recommended limits according to the probabilistic assessment; this is in relation to the criterion of residential and recreational use of water resources. However, it was identified that the child population doubles the acceptable systemic risk level according to the results of the deterministic assessment in the residential scenario. This information can be used by decision-makers to implement strategies to reduce Hg contamination and exposure of the population in Ecuadorian Amazonian rivers.

“…larvae do not exist in the scientific literature. Nematoda larvae of the Anisakidae family (Railliet and Henry, 1912) bioaccumulated lower concentrations of lead (Pb) and copper (Cu) than the host Dicentrarchus labrax (Linnaeus, 1758) (da Silva-Costa et al, 2022). The present study showed that Eustrongylides sp.…”

“…When ingested, fish can be a relevant vehicle for heavy metal transmission. Some studies (Albuquerque et al, 2021;Alcala-Orozco et al, 2020;da Silva-Costa et al, 2022;Lima et al, 2015;Silva et al, 2019) in fish from Amazonian environments, including in specimens consumed by indigenous communities (Vasconcellos et al, 2021), point to the detection of worrying levels of these metals in species of commercial interest. Human contamination by fish gains importance when considering the preference of Amazonians for this protein source, to the detriment of others (Barreto-Sa et al, 2019;Haddad-Junior et al, 2021;Lino et al, 2018;Lopes et al, 2016).…”

Introduction: Chemical pollution represents a great concern to aquatic organisms, especially fish. Metals enter the aquatic environment from a variety of sources, including natural biogeochemical cycles and anthropogenic sources such as industrial and residential effluents, mining and atmospheric sources. Objective: To describe the Eustrongylides sp. larvae and the interaction with their fish hosts as indicators of mercury (Hg) contamination in the Brazilian Amazon, and the distribution of Hg in the internal organs of fish species Hoplias malabaricus and Pygocentrus nattereri collected in oxbow lakes on the Tapajós River, in the municipality of Santarém, in the state of Pará. Methods: Total Hg was analyzed using the Direct Hg Analyzer - DMA-80. Concentrations of Hg in Eustrongylides sp. were compared with those found in the tissues/organs of the hosts H. malabaricus and P. nattereri. Hg concentrations in the host/parasite system were statistically compared using Principal Component Analysis. The bioconcentration factor (BCF) was calculated to assess the bioaccumulation capacity of metals in Eustrongylides sp. larvae, comparing the concentration of Hg in the parasite with that accumulated in the musculature of infected hosts. Results: Hg concentrations in all tissues/organs analyzed were higher in the parasitic species Eustrongylides sp. larvae when compared with those found in tissues/organs of H. malabaricus and P. nattereri. There was an inversely proportional relationship, showing that when Eustrongylides sp. larvae are present, the concentration in the parasite is higher than in the musculature of host fish H. malabaricus and P. nattereri. The BCF of Hg was found by comparing Eustrongylides sp. larvae/H. malabaricus muscle and was observed during a flood (BCF Hg = 15 364). Conclusions: The results confirm the greater bioaccumulative capacity of Eustrongylides sp. compared to its host. The data indicated the viability of using Eustrongylides sp. larvae in biomonitoring programs. It is worth mentioning that fish samples for Hg analysis must be free of parasites since their presence can alter the results.
