“…The Tl content in aquatic creatures is influenced by seawater along the coast they inhabit. The Tl concentration in seawater is about 0.2-20 µg kg −1 , affected by volcanic events, airborne particles, and deposit inflows from rivers and soil [36]. As a result, if polluted river water or sediment reaches a habitable area, it may affect the Tl concentration of aquatic species.…”

“…Toxic metal(loid)s accumulate in the food chain in natural environments [52,53]. Tl is enriched in the natural environment through anthropogenic sources (e.g., cement production and coal combination) and natural sources, such as volcanic activity and mineral ore mining [36]. Tl accumulates in plants and animals through the food chain, eventually causing harm to humans.…”

Thallium (Tl) is a rare element and one of the most harmful metals. This study validated an analytical method for determining Tl in foods by inductively coupled plasma mass spectrometry (ICP-MS) based on food matrices and calories. For six representative foods, the method’s correlation coefficient (R2) was above 0.999, and the method limit of detection (MLOD) was 0.0070–0.0498 μg kg−1, with accuracy ranging from 82.06% to 119.81% and precision within 10%. We investigated 304 various foods in the South Korean market, including agricultural, fishery, livestock, and processed foods. Tl above the MLOD level was detected in 148 samples and was less than 10 μg kg−1 in 98% of the samples. Comparing the Tl concentrations among food groups revealed that fisheries and animal products had higher Tl contents than cereals and vegetables. Tl exposure via food intake did not exceed the health guidance level.

“…In recent years, Tl has become a technology-critical element because of its utilization in semiconductor and electro-optical industries, which may contribute to new sources of Tl released to the environment [5,6]. When released into the soil, Tl can be taken up by plants and then enter the human food chain [7][8][9][10][11]. The background level of Tl in edible plants is generally low, ranging from 0.03 to 0.3 mg kg −1 [12].…”

This study investigated the uptake of thallium (Tl) by rice seedlings grown in different soils with varying physiochemical properties and Tl levels to elucidate the key factors governing soil Tl availability and accumulation in rice plants. The bioconcentration factors of Tl in rice roots (2.5–25.6) and shoots (1.5–14.7) indicated high soil Tl availability and efficient uptake and translocation of Tl in rice plants, with significant variations across soil types. Growth suppression and visual toxic symptoms, such as stem buckling, yellowish leaf tips, and withering leaf edges, occurred at low soil Tl levels due to high Tl toxicity. The accumulation of Tl by rice plants was influenced by both soil and plant-related factors. Cation exchange reactions primarily influenced the concentration of Tl in soil solution, with potassium ions (K+) acting as competitors for cation exchange sites with Tl+ ions and effective inhibitors of Tl uptake by rice plants. Increasing soil K content may mitigate soil Tl availability in contaminated soils by reducing soil Tl(I) adsorption and plant uptake. This study elucidates the key mechanisms governing soil Tl bioavailability and highlights potential management strategies to reduce Tl accumulation in crops.

“…However, its toxicity to aquatic biota is less well understood. Knowledge of Tl toxicity in aquatic systems is increasingly critical, with this trace element being considered an emerging toxicant (Batley & Campbell, 2022) because of its use in advanced technologies such as superconductors and medical imaging and its subsequent appearance in effluents related to these uses (Migaszewski & Galuszka, 2021). Studies to date using lethality as an endpoint indicate that aquatic animals are at relatively low risk of Tl toxicity.…”

The mechanisms of acute (96 h) and sub‐chronic (28‐d) toxicity of the waterborne trace metal thallium (Tl) to rainbow trout (Oncorhynchus mykiss) were investigated. Specifically, effects on branchial and renal ionoregulatory enzymes (sodium/potassium ATPase and proton ATPase) and hepatic oxidative stress endpoints (protein carbonylation, glutathione content and activities of catalase and glutathione peroxidase) were examined. Fish (19‐55 g) were acutely exposed to 0 (control), 0.9 (regulatory limit), 2004 (half the acute median lethal concentration) or 4200 (acute median lethal concentration) µg Tl L‐1 or sub‐chronically exposed to 0, 0.9 or 141 (an elevated environmental concentration) µg Tl L‐1. The only effect following acute exposure was a stimulation of renal H+‐ATPase activity at the highest Tl exposure concentration. Similarly, the only significant effect of sub‐chronic Tl exposure was an inhibition of branchial NKA activity at 141 µg Tl L‐1, an effect that may reflect the interaction of Tl with potassium ion handling. Despite significant literature evidence for effects of Tl on oxidative stress, there were no effects of Tl on any such endpoint in rainbow trout, regardless of exposure duration or exposure concentration. Elevated basal levels of antioxidant defences may explain this finding. These data suggest that ionoregulatory perturbance is a more likely mechanism of Tl toxicity than oxidative stress in rainbow trout, but is an endpoint of relevance only at elevated environmental Tl concentrations.
