“…Most existing plant uptake models were developed for neutral compounds [31,32,37,38,39,40], while most pharmaceuticals are ionisable [41]. The recently used dynamic model [31] was modified to consider additional processes relevant for ionic compounds, such as (i) adsorption to proteins, (ii) speciation and ion trapping [33] and (iii) phloem transport of weak acids.…”

“…Many emerging contaminants in TWW are ionizable. The transport of ionic compounds requires the consideration of additional processes, such as ion trap and electrical interaction [33]. Weak acids may also undergo ion trapping in the alkaline phloem sap [33] with subsequent downwards transport, while phloem transport is of marginal relevance for neutral compounds.…”

Weak acids may also undergo ion trapping in the alkaline phloem sap [33] with subsequent downwards transport, while phloem transport is of marginal relevance for neutral compounds. This study aimed to (i) adapt and parameterize a simple steady-state model for the specific situation of greenhouse-grown, TWW-irrigated lettuce in Murcia, (ii) test this simulation tool against experimental data of an EOC (carbamazepine, CBZ), (iii) predict the uptake of other EOCs (ibuprofen, IBP; ketoprofen, KTP; naproxen, NPX) for this specific situation, and (iv) to evaluate implications of irrigation with TWW containing these EOCs for food safety and human exposure via dietary intake.…”

“…All over the world, micropollutants (MPs) are detected in various types of water systems, such as surface water, groundwater and wastewater (Philip, Aravind, and Aravindakumar 2018;Yang et al 2017). The presence of MPs in these water systems raises concerns regarding ecosystems and human health (Kidd et al 2007;Krzeminski et al 2019;Oaks et al 2004;Polesel, Plósz, and Trapp 2015). Both human population and the consumption of chemicals like pharmaceuticals are increasing, hence the discharge of MPs into the environment will also increase.…”

Ozonation for micropollutant removal from wastewater treatment plant effluent is energy and costintensive because of competition between background organic matter and micropollutants. This study aims to elucidate the interference of different organic matter fractions during the ozonation of micropollutants. Wastewater treatment plant effluent was fractionated using membranes and XAD-8 resin. All membrane and resin fractions were spiked with 18 micropollutants (2 µg/L) and ozonated with 0.25, 0.5 and 1 g O 3 /g TOC. Results show that these fractions differ in their interference with the ozonation of micropollutants. Interference was lower in the smallest size fraction (<1 kDa) than in all other fractions for micropollutants with low and medium ozone reactivity. The hydrophobic neutrals and hydrophilics resin factions showed a high interference for ozonation of micropollutants with medium and high ozone reactivity, respectively. The four parameters that were analyzed (specific UV absorbance at 254 nm, fluorescence, chemical oxygen demand and nitrite) could not elucidate the differences in micropollutant removal. Still, we conclude that understanding the type of organic matter present in the matrix, is essential to optimize micropollutant ozonation and other tertiary micropollutant removal treatments.

Predicting the Accumulation of Ionizable Pharmaceuticals and Personal Care Products in Aquatic and Terrestrial Organisms

The extent to which chemicals bioaccumulate in aquatic and terrestrial organisms represents a fundamental consideration for chemicals management efforts intended to protect public health and the environment from pollution and waste. Many chemicals, including most pharmaceuticals and personal care products (PPCPs), are ionizable across environmentally relevant pH gradients, which can affect their fate in aquatic and terrestrial systems. Existing mathematical models describe the accumulation of neutral organic chemicals and weak acids and bases in both fish and plants. Further model development is hampered, however, by a lack of mechanistic insights for PPCPs that are predominantly or permanently ionized. Targeted experiments across environmentally realistic conditions are needed to address the following questions: (1) What are the partitioning and sorption behaviors of strongly ionizing chemicals among species? (2) How does membrane permeability of ions influence bioaccumulation of PPCPs? (3) To what extent are salts and associated complexes with PPCPs influencing bioaccumulation? (4) How do biotransformation and other elimination processes vary within and among species? (5) Are bioaccumulation modeling efforts currently focused on chemicals and species with key data gaps and risk profiles? Answering these questions promises to address key sources of uncertainty for bioaccumulation modeling of ionizable PPCPs and related contaminants.
