“…However, since many organohalogens have similar health effects and some have established dietary routes of exposure (that is fish and exposure via airborne pathways) (Weitekamp et al 2022 ), we can characterize the risk of traditional food consumption in our study region. This approach has been used in previous studies (Huang et al 2022 ; Naqvi et al 2020 ; Sari and Esen 2022 ). Therefore, investigating any route of exposure from organohalogens is critical to estimating the potential risk to humans following exposure from consuming contaminated food.…”

Hunting, trapping, and fishing are part of an Indigenous lifestyle in subarctic Canada. However, this lifestyle may be a route of exposure to contaminants and may pose a risk for the people who rely on a subsistence diet. Monte Carlo simulations for the chemical concentration of eight game species and one fish species were carried out by randomly sampling 10,000 samples from the contaminant measures for each species. We then calculated a probabilistic non-carcinogenic hazard quotient or carcinogenic risk values to estimate the human health risk of exposure to contaminants. Of the species examined, ducks were of concern for potential carcinogenic risk. There was a modeled probabilistic 95th-percentile risk associated with the consumption of ducks and polybrominated biphenyl (PBB) congener 153 in boys, women, and men (1.09 × 10−6, 1.57 × 10−6, and 2.17 × 10−6, respectively) and, to a lesser extent, with geese and polychlorinated biphenyl (PCB) congener 153 in men (1.19 × 10−6). Contaminant concentration in the intake rate (food consumption) for PBB congener 153 exposure risk was more important than that for PCB congener 153, where intake rate had greater relevance. The consumption of waterfowl may increase the exposure to organohalogens; however, there are health and wellness benefits associated with the harvesting and consumption of subsistence foods that must also be considered. We recommend follow-up species-specific studies focused on ducks to clarify and elucidate the results in the present study.

“…135,140,145,[151][152][153][154] Bioaccumulation and trophic transfer are important criteria for evaluating ecological and health risks. [155][156][157] There are a few field studies on bioaccumulation and trophic transfer (biomagnification) of phosphate esters. [158][159][160][161] It is also worth noting that the limited research on phosphate ester bioaccumulation and biomagnification has shown mixed results.…”

“…159,161,164 Different environmental settings, local pollution variables, the complexity of the food chain, species composition, and biotransformation could all play a role in food web transfer mechanisms that ought to be investigated further. 157,159,162,165 It is essential to acknowledge the scarcity of bioaccumulation and trophic transfer studies of alternative plasticizers other than phosphate esters despite detecting alternative plasticizers in water environments and sediments. 64,166 Therefore, we consider it an important research gap that needs urgent investigation to avoid global environmental and health issues.…”

The photosynthetic pigments, protein, macro and microelements concentrations, and fatty acids composition of Salvinia natans, a free-floating aquatic plant, were analyzed after exposure to Hoagland nutrient solution containing 1, 3, and 5 mg/L Li. The Li content of Salvinia natans grew exponentially with the Li concentration in the Hoagland nutrient solution. The exposure to Li did not induce significant changes in Na, Mg, K, Cu, and Zn content but enhanced the Ba, Cr, Mn, Ni and Mo absorption in Salvinia natans. The most abundant fatty acids determined in oils extracted from Salvinia natans were C16:0, C18:3(n6), C18:2(n6), and C18:3(n3). The photosynthetic pigments did not change significantly after exposure to Li. In contrast, chlorophyll and protein content decreased, whilst monounsaturated and polyunsaturated fatty acids content increased after the exposure to 1 mg/L Li. The results indicated that Salvinia natans exposed to low Li concentrations may be a good source of minerals, omega 6 and omega 3.
