“…Obviously, a mechanistic understanding of how crops take up and accumulate pesticides from the surrounding environment (e.g., aqueous solution) is essential for the risk assessment of pesticide accumulation in agricultural products (Pullagurala et al, 2018). Data on plant uptake is essential in developing and parameterizing models to predict pesticide accumulation and subsequent human exposure through the terrestrial food chain (Gobas et al, 2016;Li et al, 2020;Wu and Zhu, 2019).…”

“…In the second cluster, with more elaborated TK models, three studies emphasize the importance of considering biotransformation, that is the possi ble dégradation of the parent compound into métabolites, that may be even more toxic (Firdaus et al, 2018;Gao et al, 2013;Wu and Zhu, 2019), the work by Wu and Zhu (2019) having the particularity to concern plants. One study has accounted for time-variable exposure (Rubach et al, 2010) going so far as to propose the 95% dépuration time (£9 5 ) as a complément to the BCF.…”

A wide diversity of plant protection products (PPP) is used for crop protection leading to the contamination of soil, water, and air, which can hâve ecotoxicological impacts on living organisms. It is inconceivable to study the effects of each compound on each species from each compartment, experimental studies being time consuming and cost prohibitive, and animal testing having to be avoided. Therefore, numerous models are developed to assess PPP ecotoxicological effects. Our objective was to provide an overview of the modelling approaches enabling the assessment of PPP effects (inc.luding biopesticides) on the biota. Six categories of models were inventoried: QSAR, DR and TKTD, population, multi-species, landscape, and mixture models. They were developed for various species (terrestrial and aquatic vertebrates and invertebrates, primary producers, micro-organisms) belonging to diverse environmental compartments, and address different goals (e.g., species sensitivity or PPP bioaccumulation assessment, ecosystem ser vices protection). Among them, mechanistic models are increasingly recognized by EFSA for P P P regulatory risk assessment but, to date, remain not considered in notified guidance documents. The strengths and limits of the reviewed models are discussed together with improvement avenues (multi-generational effects, multiple biotic and abiotic stressors. ..). This review also underlines a lack of model testing by rneans of fleld data and of sensitivity and uncertainty analyses. Accurate and robust modelling of PPP effects and other stressors on living organisms, from their application in the ffeld to their functional consé quences on the ecosystems at different scales of time and space, would help going towards a more sustainable management of the environment.

“…Briggs et al [39] proposed that the uptake of neutral chemicals by plants would imply a maximum translocation at a log Kow∼1.78 compared to particularly hydrophobic (high log Kow) and hydrophilic (low log Kow) conditions. Plant uptake depends on both species and compounds [34], and root uptake from soil and/or water is the major pathway [20] for most hydrophobic organic compounds (log Kow > 3.0). As CBZ is hydrophilic in nature (log Kow = 2.45), it appears more in the aqueous phase than being attached to soil particles.…”

“…The new EU regulation on minimum water reuse requirements for agricultural irrigation purposes was published in 2020 [5]. As emerging pollutants are not regulated by this reuse regulation, predicting the translocation of organic pollutants to plants is crucial to ensure the quality of agricultural goods and to assess the risk of human exposure via the food web [20]. Of all the EU reuse regulation indications, drip irrigation systems are considered the safest.…”

Water and food security are of global concern. Improving knowledge on crops’ potential uptake of pharmaceutical compounds (PhCs) is necessary to guarantee consumer health and improve the public’s perception of reclaimed water reuse. This study aimed to determine how water management (bottom-up applied for being supplied by Subsurface Drip Irrigation) and the plant rhizosphere effect on the uptake of PhCs. Five PhCs were mixed: atenolol, carbamazepine, dicoflenac, ibuprofen and valsartan. A total of 5 treatments were considered: 3 concentrations of PhCs in agricultural volcanic soil: 0.1, 10 and 100 µg·L−1; 0.1 µg·L−1 in sterilized soil; and a blank with three plant replications at 30, 45, and 60 days after emerging. The maximum quantity of the added PhCs was 100 µg·kg soil−1. A variant of the QuEChERS method was followed to extract PhCs from samples. The limits of quantification were between 10 ng·L−1 and 100 ng·L−1 in extracts. No PhCs over the limits of detection were detected (0.06–0.6 µg·kg−1 of dry plant sample). Hence, the described water reuse methodology poses a negligible consumer risk, which contrasts with hydroponic systems in which this risk has been shown. The results are discussed in terms of the effects of irrigation system, water management and the soil-plant barrier.
