“…For instance, some studies have demonstrated that heavy metals from the environment may bioaccumulate in commonly consumed fruits, vegetables, and cereals. 24 - 26 Upon ingesting these contaminated crops, the heavy metals may accumulate in the meat and guts of the animals, 16 , 27 which raises concerns about the health of individuals who consume grasscutter digesta. Here, we assessed the knowledge and perceptions of respondents about the safety of consuming grasscutter digesta and evaluated the potential risk of heavy metal poisoning from ingesting this spice.…”

Grasscutter (cane rat/ Thryonomys swinderianus) digesta is used as a spice in Ghana. Research shows that heavy metals from the environment may accumulate in the internal organs of grasscutters, which raises concerns about the possible contamination of grasscutter digesta, too, with heavy metals. Although grasscutter meat in Ghana has been described as safe for consumption, information is lacking on the health risks associated with ingesting the digesta. This study, therefore, aimed to assess the knowledge and perceptions of a merchant and a consumer about the safety of ingesting grasscutter digesta and to evaluate potential health risks from exposure to heavy metals from the spice. A total of 12 digesta samples were analyzed to evaluate potential health risks from exposure to Cd, Fe, Hg, and Mn using a Varian AA240FS Atomic Absorption Spectrometer. The levels of Cd, Hg, and Mn were below the detection limit of 0.01 mg/kg digesta. Also, the estimated daily intake of Fe (0.02 mg/kg) was less than the maximum allowable dose recommended by the US EPA (0.7 mg/kg). The hazard indices of Fe for daily and weekly consumption were <1, suggesting that the consumers may be safe from iron poisoning. Because grasscutter digesta is a relatively expensive spice, it is unlikely to be consumed daily by the average Ghanaian. Moreover, if 10 g of digesta is consumed daily, it can be safely ingested about 971 times in a month. Domestication of grasscutters may be a useful approach to monitor their diet and consequently the quality of their digesta.

“…The target hazard quotient (THQ) assesses the non-carcinogenic risk level from pollutant exposure. THQ values below 1 indicate insignificant health threats, while THQ values ≥1 indicate potential health risks requiring corrective action [63]. The Hazardous Index (HI) is the cumulative sum of the Target Hazard Quotient (THQ) values for all trace elements present in an individual's exposure.…”

The Tocantins–Araguaia basin is one of South America’s largest river systems, across three Brazilian states (Maranhão, Tocantins, and Pará), within the Legal Amazon region. Despite draining extensive Cerrado savanna and rainforest ecosystems, it has suffered significant degradation, notably in the past 40 years. Human activities, including agricultural expansion, deforestation, and the introduction of non-native species, have worsened the environmental damage, which is alarming since many residents and villages along the middle Tocantins River rely on it for water supply, recreation, and fishing. This study assessed the concentration of potentially toxic and essential elements in water samples from four sampling sites distributed along the middle Tocantins River. The monitoring occurred throughout 2023, involving the measurement of parameters both on-site and in the laboratory. Water quality and its health implications were evaluated using the Weighted Arithmetic Water Quality Index (WAWQI), the Water Quality Index (WQI), and the health risk assessment index. The levels of aluminum, copper, iron, magnesium, and selenium exceeded legal standards. Seasonal fluctuations indicate a complex dynamic influenced by climatic or seasonal factors, with February showing the highest values. Site P1, located in urban areas, exhibited elevated mean concentrations for conductivity, total dissolved solids (TDS), and chlorophyll, indicating the need for continuous monitoring. The nitrogen concentrations at P1 raise concerns regarding drinking water quality, which is a concern for the region’s residents who use untreated river water. Despite seasonal variations in element concentrations, the overall WAWQI categorized all sections as “Excellent,” and the WQI rated as “Good.” Human health risk assessments detected no risks, but continuous monitoring and interventions are crucial for sustained water quality improvement.

“…kidney failure, blood and lung cancers, skeletal deformities, and osteoporosis [ 14 ]. Studies that analyse the concentrations of toxic heavy metals in widely consumed foods are therefore beneficial to protect human health from the harmful effects of hazardous metals [ 15 , 16 ]. The bioavailability and occurrence of heavy metals, however, are influenced by other factors such as soil pH and texture, organic matter content, and interactions among elements [ 17 ].…”
