“…Some of these toxic and essential elements have been reported in herbal medicinal products [ 5 ], in snacks [ 6 ], and aquatic organisms including fish [ 7 , 8 ]. A certain level of some elements that exceed the maximum allowable limit (MAL) in the intake are non-essential and toxic (NETs) to humans (e.g., arsenic (As), antimony (Sb), cadmium (Cd), mercury (Hg), and lead (Pb)) [ 9 , 10 ]; however, there are several other elements, including some metals (Others), which their specific biological functions are not well known. In this study, we hypothesized that certain toxic elements might be accumulated in larger quantities in the tissues of aquatic organisms at higher trophic levels (TLs).…”

“…Moreover, Canli & Atli [ 18 ] reported fish-specific and tissue-specific disparities in the accumulation of different elements in fish bodies. There are several previous studies, in particular, analyses of mercury in fish in Sri Lanka (e.g., [ 9 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ]). Temporal and spatial monitoring of such an element in the case of the concentrations in tissues is essential in identifying current and future trends, especially for widely consumed aquatic species, such as yellowfin tuna (YFT) (Scientific name: Thunnus albacares ) in Sri Lanka.…”

Thirty-six elements are categorized as essential but toxic in excess amount (EBTEs), non-essential toxic (NETs), and Other in 29 different edible aquatic species dwelling in offshore pelagic, and coastal and estuarine (CE) ecosystems were investigated in Sri Lanka. Elements were analyzed using an energy-dispersive X-ray fluorescence (EDXRF) spectrometer, and an NIC MA-3000 Mercury Analyzer. EBTEs showed a negative relationship, whereas NETs showed a positive relationship between the concentration (mg/kg wet weight) and trophic levels in both ecosystems. EBTEs showed trophic dilution, whereas NETs showed trophic magnification. Some elements in a few organisms exceeded the maximum allowable limit which is safe for human consumption. There was a positive relationship (R2 = 0.85) between the concentration of mercury and body weight of yellowfin tuna (YFT). For the widely consumed YFT, the calculated hazard index (HI) for the non-carcinogenic health and exposure daily intake of NETs for adults were 0.27 and 9.38 × 10−5 mg/kg bw/day, respectively. The estimated provisional tolerable weekly intake (PTWI) (μg/kg bw/w) was 0.47 for arsenic and 0.05 for antimony, cadmium, mercury, and lead. The HI and PTWI values were below the recommended limits; thus, consumption of YFT does not pose any health risk for Sri Lankan adults.

“…Cadmium is an unessential heavy metal, is highly toxic to plants and represents one of the most dangerous environmental challenges worldwide. The European Food Safety Authority recommended the tolerable daily intake is 0.358 μg Cd kg −1 body weight, which is lower than the World Health Organization's (WHO's) recommended value (25 µg kg −1 BW month −1 ) (Jinadasa et al, 2019). Cadmium is a toxic trace metal that is detrimental to different cereal crops including wheat since it can typically block the essential plant nutrients transport in different plant organs, such as roots, shoots and grain during seedlings' emergence to through to their growth and developments stages (Mahawar et al, 2021).…”

Farmers use wastewater for irrigation in many developing countries, for example Bangladesh, India, China, Sri Lanka and Vietnam because they have limited access to clean water. This study explored cadmium (Cd) bioaccumulation in two spring wheat cultivars (cv. Mustang and Lancer), which were grown in different concentrations of Cd (0,1, 2, 4, and 8 mg kg−1) in agricultural soils. The half maximum inhibitory concentration (IC50) values were 4.21 ± 0.29 and 4.02 ± 0.95, respectively, whereas the maximum health risk index (HRI) was 3.85 ± 0.049 and 5.33 ± 0.271, respectively, for Mustang and Lancer. In other words, the malondialdehyde content increased significantly in Mustang (around five-fold) and Lancer (around four-fold) compared with the control treatment. Results revealed that Cd content was well above the acceptable limit (HRI >1) in the two cultivars when exposed to different levels of Cd stress. The tolerant cultivar (Mustang) has potential to chelate Cd in the nonedible parts of plants in variable fractions and can be used efficiently to improve growth and macro- and micro-nutrients content while reducing Cd concentration in plants in Cd-contaminated soil. It can also diminish the HRI, which may help to protect humans from Cd risks. The two cultivars’ nutrient availability and sorption capacity significantly shape their survival and adaptability under Cd stress. Based on what is documented in the current study, we can conclude that Mustang is more tolerant and poses fewer health hazards to people than Lancer because of its capacity to maintain grain macro- and micro-nutrients under Cd stress.

“…Total THQ value of all heavy metals followed the descending order of Katsuwonus pelamis > Euthynnus affinis > Thunnus albacares. Similarly, consumption of tuna species from the eastern Pacific Ocean (Ordiano-Flores et al 2011), the Indian Ocean around Sri Lanka (Jinadasa et al 2018), and Galicia-Spain (Núñez et al 2018) were found to be safe for human consumption without no threat to health.…”

This study was performed to determine the concentrations of copper (Cu), zinc (Zn), and lead (Pb) in the gill, liver, muscle, and tail fin tissues of Euthynnus affinis, Katsuwonus pelamis, and Thunnus albacares from Oman Sea. All samples were analyzed using a flame atomic absorption spectrophotometer and the results were expressed as μg g −1 dry weight. Metal concentrations were significantly higher in the liver than other tissues in three species (with some exceptions) (p < 0.05). The concentrations of metal accumulation in tissues of tuna species followed the Zn > Cu > Pb. Correlation matrix and principal component analysis (PCA) revealed that Zn and Pb have anthropogenic sources. Estimated daily intake (EDI) in three tuna species for heavy metals were below the tolerable daily intake (TDI). Also, the mean target hazard quotient (THQ) based on studied metals in three tuna species was below 1, which suggests that consumption of these fish can be safe for human health in the Oman Sea.
