“…These scenarios are different from those that actually occur in the Mezquital Valley but are undoubtedly important references to consider in future research, which mainly concern factors that influence the transportation and observed destination of EDCs and analysis in soil, roots, leaves, and edible crops [55]. Yet, there are undoubtedly important references to consider in future research studies, which are mainly regarding the factors influencing the transport and observed destination of EDCs [56,57], in an analytical experience for detection in soil, roots, leaves, and part of the edible cultivation [52], as well as in the risk assessment associated with the presence of EDCs in crops in the region [49,58].…”

The aim of the research was to show the presence of micropollutants contained in the wastewater of Mexico City within the distribution canals of the Mezquital Valley (MV), as well as their retention in agricultural soil and aquifers. This system constitutes the world's oldest and largest example of the use of untreated wastewater for agricultural irrigation. The artificial recharge associated with the MV aquifers, with groundwater extracted for human consumption showing its importance as a water resource for Mexico City. The results of sampling show the presence of 18 compounds, with 10 of these considered as endocrine disruptor compounds (EDCs). The concentration of these pollutants ranged from 2 ng/L for 17 β-estradiol to 99 ng/L for DEHP, with these values decreasing throughout the course of the canals due to the wastewater dilution factor, their retention in agricultural soil, and their accumulation in the local aquifer. The main mechanisms involved in natural attenuation are adsorption, filtration, and biodegradation. Drinking water equivalent levels (DWELs) were estimated for 11 compounds with regard to acceptable daily intakes (ADIs), by assuming local exposure parameters for a rural Mexican population. These were compared with the maximum groundwater concentrations (Cgw) to screen the potential risks. The very low ratios of Cgw to DWELs indicate no appreciable human health risk from the presence of trace concentrations of these compounds in the source of drinking water in the MV. Despite this, far from being exceeded after more than 100 years of irrigation with residual water, the natural soil attenuation seems to remain stable.

“…Pharmaceuticals often detected in sewage sludge include non-steroidal anti-inflammatory drugs (NSAIDs), blood thinners, psychiatric drugs, antidiuretics and β-blockers [47][48][49]. Plant uptake of a wide variety of pharmaceutical groups like NSAIDs, antihistamine, β-blockers, calcium channel blockers, antiepileptics, steroid hormones, antidepressants, antineoplastic agents, anti-itch compounds, x-ray contrast agents, lipid-lowering agents, benzodiazepines, tranquilizers and veterinary drugs from soil and contaminated water has been observed and studied [50][51][52]. Wu et al reported that a primary pathway for contamination by pharmaceuticals in food crops is through irrigation water [53,54].…”

In the race to enhance agricultural productivity, irrigation will become more dependent on poorly characterized and virtually unmonitored sources of water. Increased use of irrigation water has led to impaired water and soil quality in many areas. Historically, soil salinization and reduced crop productivity have been the primary focus of irrigation water quality. Recently, there is increasing evidence for the occurrence of geogenic contaminants in water. The appearance of trace elements and an increase in the use of wastewater has highlighted the vulnerability and complexities of the composition of irrigation water and its role in ensuring proper crop growth, and long-term food quality. Analytical capabilities of measuring vanishingly small concentrations of biologically-active organic contaminants, including steroid hormones, plasticizers, pharmaceuticals, and personal care products, in a variety of irrigation water sources provide the means to evaluate uptake and occurrence in crops but do not resolve questions related to food safety or human health effects. Natural and synthetic nanoparticles are now known to occur in many water sources, potentially altering plant growth and food standard. The rapidly changing quality of irrigation water urgently needs closer attention to understand and predict long-term effects on soils and food crops in an increasingly fresh-water stressed world.

“…Antibacterial compounds can displace microbes that are antagonistic toward plant pathogens, allowing them to increase in numbers and therefore have a higher chance to establish an infection (Mulligan et al, 1982;De Vries-Hospers et al, 1991;Azevedo et al, 2015). Previous studies have shown that certain pharmaceutical products can have detrimental impacts on plants (Liu et al, 2009a;Madikizela et al, 2018). The impacts of CECs on disease severity or disease severity index varied with the CEC: TMP-H had a higher severity index earlier in the season (week 2-4), while SMX at both concentrations had a greater impact later in the season (week 5-9).…”

“…In our study we subject plants and microorganisms to concentrations similar to those found in treated wastewater effluent, or reclaimed water. A number of previous studies have found direct phytotoxic effects of various CECs, however these studies used concentrations that are higher than those found in typically treated wastewater effluent (D'Abrosca et al, 2008;Liu et al, 2009a;Pino et al, 2016;Madikizela et al, 2018). Some studies found phytotoxic effects to developing plants, but did not grow the plants in soil (D'Abrosca et al, 2008;Pino et al, 2016), which can impact plants uptake of chemicals through the roots (Pan and Chu, 2017).…”

Agriculture production in California is negatively impacted by soilborne fungi, such as Verticillium dahliae, and limited water availability for irrigation. Some regions have adapted the use of recycling wastewater, i.e., reclaimed water, to supplement the potable water supply. Wastewater purification is not fully efficient at removing all contaminants and small amounts of pharmaceutical products, known as chemicals of emerging concern (CECs), remain. Acetaminophen, trimethoprim, sulfamethoxazole and gemfibrozil are some of the most common CECs found in treated wastewater and were therefore used in this study. These CECs were evaluated for their potential to interact with microorganisms directly, or for their ability to alter the development of Verticillium wilt disease in eggplants. The microorganisms Verticillium dahliae, Fusarium oxysporum f. sp. lycopersici, Piriformospora indica, Phytopthora capsici, and Bradyrhizobium japonicum were used for in vitro growth assays in the presence of CECs. CECs induced varying responses in strains of the same fungi by promoting growth of one strain while inhibiting growth of the other. CECs influenced spore germination of V. dahliae and F. oxysporum. Greenhouse experiments in which Solanum melongena (eggplants) were inoculated with V. dahliae and irrigated with CECs were used to evaluate the impacts of these chemicals on disease development. Overall our results found that most of the organisms we tested were sensitive to the CECs. P. capsici was found to be the most sensitive microorganism, while B. japonicum growth was unaffected by the CECs at the concentrations used. The greenhouse assays results indicated that plant disease severity may be influenced by given CECs at certain stages of plant growth. Overall the results of this study indicate that the concentrations of CECs found in reclaimed water are occurring at biologically relevant concentrations.
