“…Similarly Shenker et al (2011) found the largest concentrations in the leaves followed by the concentrations in the roots, stems, and fruits of cucumber plants. The high accumulation in the leaves of green pea plants is associated with the transpiration stream and not the restricted transfer of neutral molecules of low MW, lipophilicity, and number of H-bonds (Kumar and Gupta, 2016) through the plant bodies (e.g., Goldstein et al, 2014;Hurtado et al, 2016;Kodešová et al, 2019a, b;Malchi et al, 2014;Montemurro et al, 2017;Mordechay et al, 2018;Shenker et al, 2011, Winker et al, 2010Wu et al, 2013) due to a passive diffusion through lipid bilayer membranes (Chuang et al, 2019). The lower accumulation in the pods is explained by the significantly shorter exposure to the contamination and a lower transpiration of pods in comparison to that in the leaves.…”

Treated water from wastewater treatment plants that is increasingly used for irrigation may contain pharmaceuticals and, thus, contaminate soils. Therefore, this study focused on the impact of soil conditions on the root uptake of selected pharmaceuticals and their transformation in a chosen soil–plant system. Green pea plants were planted in 3 soils. Plants were initially irrigated with tap water. Next, they were irrigated for 20 days with a solution of either atenolol (ATE), sulfamethoxazole (SUL), carbamazepine (CAR), or all of these three compounds. The concentrations of pharmaceuticals and their metabolites [atenolol acid (AAC), N1-acetyl sulfamethoxazole (N1AS), N4-acetyl sulfamethoxazole (N4AS), carbamazepine 10,11-epoxide (EPC), 10,11-dihydrocarbamazepine (DHC), trans-10,11-dihydro-10,11-dihydroxy carbamazepine (RTC), and oxcarbazepine (OXC)] in soils and plant tissues were evaluated after harvest. The study confirmed high (CAR), moderate (ATE, AAC, SUL), and minor (N4AC) root uptake of the studied compounds by the green pea plants, nonrestricted transfer of the CAR species into the different plant tissues, and a very high efficiency in metabolizing CAR in the stems and leaves. The results showed neither a synergic nor competitive influence of the application of all compounds in the solution on their uptake by plants. The statistical analysis proved the negative relationships between the CAR sorption coefficients and the concentrations of CAR, EPC, and OXC in the roots (R = –0.916, –0.932, and –0.925, respectively) and stems (R = –0.837, –0.844, and –0.847, respectively).

“…In addition to charged species and hydrophobicity, the bioaccumulation of pharmaceuticals could also be affected by chemical molecular weight (MW), plant physiology, metabolism, exposure time, and plant growth rates, etc. For example, MW is considered as another factor that associate with the membrane permeability (Kumar and Gupta, 2016;Topp et al, 1986). Studies on diffusion have indicated that the compounds with MW > g/mol have the restricted membrane permeability (Camenisch et al, 1998), while the compounds with MW > 1000 g/mol are impossible to be absorbed by cells (Sanderson et al, 2004).…”

Pharmaceuticals in agricultural soils originating from irrigation with treated wastewater and landapplied biosolids can enter field crops. However, little is known about the role of pore water in plant uptake of pharmaceuticals from soil. In this study, the fate, uptake and distribution of fifteen commonly used pharmaceuticals in soil-water-radish systems were investigated to examine the relationship between the accumulation and their physicochemical processes in soils. The results indicate that the distribution of pharmaceuticals between soil and pore water, as well as their biodegradation, combined to govern the bioavailability of pharmaceuticals to plant uptake. Fourteen out of 15 pharmaceuticals could enter radish tissues in which the accumulation ranged from 2.1 to 14080 ng/g. Comparison of bioconcentration factors (BCFs) on the basis of pharmaceutical concentration in bulk soil vs. in pore water implies that pharmaceuticals present in soil pore water are the major bioavailable fractions to plant uptake. The pore water-based BCFs exhibited a positive linear relationship with log Dow for the pharmaceuticals with > 90% as neutral species in soil pore water, while such relationship was not observed between bulk soil-based BCFs and log Dow mainly due to sorption by soil. Other than hydrophobicity, the dissociation of ionizable pharmaceuticals in the soil pore water and (or) root cells may lead to the "ion-trap" effects and thus influence the uptake and translocation process. The large molecular size pharmaceuticals (e.g., tylosin) manifested a minimum uptake due plausibly to the limited permeability of cell membranes.

“…Such problems are mitigated in the model developed in this study, which can be used in various applications, such as phytoremediation involving uptake and metabolization processes of toxic compounds from contaminated soils (e.g., Ouyang, 2002), pesticides fate assessment (e.g., Legind et al, 2011), remediation of contaminated groundwater plumes (e.g., Hong et al, 2001), assessment of salinity in agricultural arid areas (e.g., Trapp et al, 2008), and air pollution removal by urban vegetation (e.g, Yang et al, 2008). To further extend the range of the model applicability, future research should focus on the modification of the model structure to consider DPU of electrolytes and refine the description of the root uptake mechanism of large molecules (Kumar & Gupta, 2016).…”

Food contamination is responsible for thousands of deaths worldwide every year. Plants represent the most common pathway for chemicals into the human and animal food chain. Although existing dynamic plant uptake models for chemicals are crucial for the development of reliable mitigation strategies for food pollution, they nevertheless simplify the description of physicochemical processes in soil and plants, mass transfer processes between soil and plants and in plants, and transformation in plants. To fill this scientific gap, we couple a widely used hydrological model (HYDRUS) with a multicompartment dynamic plant uptake model, which accounts for differentiated multiple metabolization pathways in plant's tissues. The developed model is validated first theoretically and then experimentally against measured data from an experiment on the translocation and transformation of carbamazepine in three vegetables. The analysis is further enriched by performing a global sensitivity analysis on the soil-plant model to identify factors driving the compound's accumulation in plants' shoots, as well as to elucidate the role and the importance of soil hydraulic properties on the plant uptake process. Results of the multilevel numerical analysis emphasize the model's flexibility and demonstrate its ability to accurately reproduce physicochemical processes involved in the dynamic plant uptake of chemicals from contaminated soils.
