Multispecies Biomonitoring of Metal(loid) Contamination and Human Health Risk in a Peri-Urban Transboundary River System (Brazil–Paraguay)
Urban and peri-urban river systems subjected to intensive agriculture are vulnerable to diffuse metal(loid) inputs, yet the integration of hydrological compartments, bioindicators, and human health risk remains poorly explored. This study investigated the seasonal dynamics, bioaccumulation patterns, and potential human health risks associated with metal(loid)s in the Santa Virgem River (Brazil–Paraguay border), using water from backwater zones an…
Assessment of the Risk to Human Health and Pollution Levels Due to the Presence of Metal(loid)s in Sediments, Water, and Fishes in Urban Rivers in the State of Mato Grosso do Sul, Brazil
This study aimed to assess the pollution levels, sources, ecological risk, and human health risks of metal(loid)s in water, sediment, and muscle tissue of Prochilodus lineatus and Pimelodus maculatus from rivers in the state of Mato Grosso do Sul, Brazil. The metal(loid)s content in river sediment, water, and fish tissue were determined by inductively coupled plasma optical emission spectrometry. Sediment pollution assessment was carried out by g…
Assessment of Metal(loid)s in Fern Amauropelta rivularioides (Fee), Soil, and River Water in a Peri-Urban Agriculture Area on the Brazil–Paraguay Border
This study examined the temporal dynamics of metal(loid) concentrations in agricultural soils, fern Amauropelta rivularioides, and surface waters in a peri-urban region on the Brazil–Paraguay border during 2019–2020. Elevated levels of As, Se, Co, Mn, Cu, and Zn raised concerns about environmental and human health risks, especially when compared to international guidelines. Post-harvest and pre-harvest periods, particularly during corn cultivatio…
Assessment of Metal(loid)s and Nonmetals Contamination in Soils of Urban Ecological Parks in Brazil
Metal(loid)s and nonmetals in the soil of urban parks can pose risks to human health. Thus, we aimed to study the soil elemental content, soil types and their pH, contamination factor, geo-accumulation index, pollution load index, total carcinogenic risk, and hazard quotient for children and adults by ingestion, inhalation, and dermal routes contact in ecological parks (EP) in Central-West Brazil. In Lago do Amor EP, high concentrations of Mg and…
Casearia sylvestris var. lingua (Càmbess.) Eichler leaves aqueous extract improves colon inflammation through mucogenic, antioxidant and anti-inflammatory actions in TNBS- induced IBD rats
Faeces of Capybara (Hydrochoerus hydrochaeris) as a Bioindicator of Contamination in Urban Environments in Central-West Brazil
Along with exposure to parasites and other biological disease vectors, animal faeces can also contain heavy metals and metalloids. We quantified metals, metalloids, and non-metals in the faeces of capybara (Hydrochoerus hydrochaeris) that live in parks in the city of Campo Grande (Brazil). Quantification of metalloids was obtained after acid digestion using an inductively coupled plasma optical emission spectrometer. Higher mean concentrations in…
Monitoring of Metal(loid)s Using Brachiaria decumbens Stapf Leaves along a Highway Located Close to an Urban Region
Studies on tollbooth workers involving the concentration of metal(loid)s in highway dust are scarce. We aimed to assess the levels of metal(loid)s in soils and washed and unwashed leaves of Brachiaria decumbens on roadsides. Dust deposition and heavy metal content in the leaves are used to estimate the exposure of tollbooth workers to oral, inhalation, and dermal ingestion of metals in highway dust. The concentrations of aluminum (Al), arsenic (A…
Indirect Methods to Determine the Risk of Damage to the Health of Firefighters and Children Due to Exposure to Smoke Emission from Burning Wood/Coal in a Controlled Environment
People are constantly exposed to particulate matter and chemicals released during fires. However, there are still few studies on gas and particulate emissions related to exposure to burning firewood and charcoal during forest fires, making it difficult to understand the effects on the health of the population. The objective of this study was to quantify the metal(loid)s present in the smoke from wood and charcoal fires through the deposition of m…
Exposure to Toxic Metals and Health Risk Assessment through Ingestion of Canned Sardines Sold in Brazil
The presence of heavy metals in the environment is increasing, which can be a danger to public health. Fish exposed to contaminated environments tend to have higher concentrations of some metals in their tissues. Monitoring these elements remains urgent as it is a matter of global concern. Canned sardines from the Brazilian market were analyzed for elements (Al, As, Ba, Cd, Co, Cr, Cu, Fe, Ni, Pb, Se, and Zn) of metals and metalloids, including s…
Transfer of Metal(loid)s from Soil to Leaves and Trunk Xylem Sap of Medicinal Plants and Possible Health Risk Assessment
The objective of the present study was to investigate metal(loid)s in soils, in the trunk xylem sap and in the leaves of the Dipteryx alata plant located near the highway with high vehicle traffic in agricultural regions and near landfills, and to assess the transfer of metal(loid)s from soil to plant and possible health risk assessment. Trunk xylem sap, leaves and soil samples were collected at three sites near the highway. The analysis of trace…
High Concentration of Heavy Metal and Metalloid Levels in Edible Campomanesia adamantium Pulp from Anthropic Areas
This study aimed to quantify the extent of heavy metal, non-metal and metalloid levels in the Campomanesia adamantium pulp obtained from an area crossed by road experiencing high large vehicle traffic and intensive agriculture modern farming, to monitor the health risks associated with pulp consumption by humans. For this purpose, in three spots located within this area, ripe fruits were collected on the roadside, bush and farm-margin. Pulp sampl…
Assessment of Trace Elements Supply in Canned Tuna Fish Commercialized for Human Consumption in Brazil
This study evaluates the elemental content in 4 types of canned tuna fish groups, each with 4 brands that are commercialized for human consumption in Brazil. The results are based on trace elements in canned tuna fish quantified by ICP OES and a comparison to limit levels set by the FAO/WHO. We also checked the carcinogenic risk (CR), non-carcinogenic risk (Hazard Index (HI) and Hazard Quotient (HQ)), and pollution index (PI) for the studied cann…
Human Health Risk Assessment through Roasted Meats Consumption
Data on the content of metals and metalloids in roasted meats with different types of wood and charcoal are still scarce in the literature. The concentrations of metals (Al, Cr, Cd, Cu, Fe, Mg, Mn, Mo, Ni, V, and Zn) and metalloid (As) were determined by inductively coupled plasma mass spectrometry (ICP-OES) after microwave digestion, and the estimated daily intake ( EDI ) for adults was assessed to determine the hazard quotient ( HQ ). The conce…
