Trophic transfer of PFAS from tomato (Solanum lycopersicum) to tobacco hornworm (Manduca sexta) caterpillars

Chemicals/materials of emerging concern in farmlands: sources, crop uptake and potential human health risks

“…In a study on PFAS-accumulated leaf tissues of Solanum lycopersicum , the biomagnification factors (BMFs) and assimilation efficiencies (AEs) were five-fold higher in tobacco hornworm ( Manduca sexta ), fed on those tissues. 149 The uptake and elimination patterns of seven different PFAS were found to be very similar, implying that PFAS accumulated in the leaf tissues were easily transferred to herbivores. 149 In addition to plants, trophic transfers can occur to other animals with different efficiencies.…”

“…149 The uptake and elimination patterns of seven different PFAS were found to be very similar, implying that PFAS accumulated in the leaf tissues were easily transferred to herbivores. 149 In addition to plants, trophic transfers can occur to other animals with different efficiencies. In the agricultural area in Okanagan (British Columbia, Canada), the birds showed high sensitivity to persistent chemicals, 150 and the average values (μg g −1 lipid weight) of ∑PBDE, ∑PCB, DDE and dieldrin in Cooper's hawk were 1.03, 0.76, 110.3 and 0.21, respectively.…”

“…Such insights have significant importance in formulating effective strategies for controlling the entry of CECs into the terrestrial food chain. Cabbage, 134 lettuce, 125 strawberry, 125 candytufts, 122 wheat, 24,136 tomato, 85,149 rice seedlings, 30 and corn 127 are the major plants considered individually for determining the uptake of CECs such as PFAS, PPCPs, PBDEs, MPs/NPs, and nanoparticles. To understand more about the crop plants–CEC interactions, it is necessary to include studies on uptake mechanisms for different CECs, depending on the nature of chemicals or materials, by plant or animal species either alone or in a mixed form.…”

Environmental Fate of Cl-PFPECAs: Accumulation of Novel and Legacy Perfluoroalkyl Compounds in Real-World Vegetation and Subsoils

“…Currently, the primary route of PFAS exposure in the general human population is via consumption of drinking water and food, although respiratory and dermal-contact exposures are also possible. , While direct exposure through manufactured products and drinking water can be reasonably managed, indirect exposures from accumulation in aquatic and terrestrial food sources are more difficult to mitigate . PFAS introduction to food webs, either through ingestion of PFAS-contaminated produce , or animals reliant on these systems, − remains a complex and ever-developing issue, with sources of PFAS varying from ambient atmospheric deposition, precipitation, , irrigation using contaminated water, − or land-applied sludge or biosolids. − Among PFAS sources, one of the most common is atmospheric deposition from fluorochemical-use or -manufacturing facilities, − which can release large quantities of PFAS regionally. Therefore, determining vegetative bioaccumulation in industrialized regions is an essential component of risk assessment.…”
