“…A relevant example is the detection of sulfamethazine and sulfadimethoxine in groundwater near a confined animal feeding operation in Weiser, ID (Batt et al, 2006). Our research is consistent with many other reports that sulfonamide antibiotics move in higher concentrations and to greater distances in soil than hormones, tetracyclines, macrolides, or human pharmaceuticals (Kay et al, 2005b; Wehrhan et al, 2007; Salvia et al, 2014; Zentner et al, 2015). Such movement is a function of sulfonamide charge characteristics as controlled by pH.…”

Transport of Potential Manure Hormone and Pharmaceutical Contaminants through Intact Soil Columns

Although adding manure to agricultural soils is a commonly practiced disposal method and a means to enhance soil productivity, potential environmental contamination by any associated chemicals of emerging concern (CECs) such as hormones and pharmaceuticals is not well understood. Our objective was to provide field‐relevant predictions of soil transport and attenuation of 19 potential manure CECs using undisturbed soil columns irrigated under unsaturated conditions. The CEC concentrations in leached water were monitored for 13 wk using high performance liquid chromatography–time of flight–mass spectrometry (HPLC‐TOF‐MS), after which time soil in the cores was removed and sampled for extractable CECs. Compounds quantified in column leachate included all four of the added sulfonamide antibiotics and the nonsteroidal, anti‐inflammatory drug flunixin. Only trace amounts of several of the seven hormones, five remaining antibiotics, and two antimicrobials leached from the columns from exogenous soil additions. Soil residues of all 19 compounds were detected, with highest extractable amounts for 17α‐hydroxyprogesterone > triclosan (antimicrobial) > flunixin > oxytetracycline. Those CECs with the highest recoveries as calculated by summing leached and extractable amounts were flunixin (14.5%), 17α‐hydroxyprogesterone (5.3%), triclosan (4.6%), and sulfadimethoxine (4.8%). Manure management to prevent CEC contamination should consider the potential environmental problems caused by negatively charged compounds with the greatest mobility (flunixin and sulfadimethoxine) and those that have long residence times in soil (triclosan, 17α‐hydroxyprogesterone, flunixin, and oxytetracycline). Flunixin is particularly important given its mobility and long residence time in soil. Core Ideas Four sulfonamide antibiotics and the drug flunixin leached through soil columns. Trace amounts of nonsulfonamide antibiotics were detected in column leachate. Soil extracts contained 17α‐hydroxyprogesterone > triclosan > flunixin > oxytetracycline. The highest recoveries were observed for flunixin and 17α‐hydroxyprogesterone.

“…Nevertheless, in an attempt to understand the potential human food chain contamination and based on studies described in literature, many of the routes are postulated: contamination of seawater (Buchanan 1971;Carpenter and Smith 1972;Lusher 2015), contamination of soil, waste water and sludge (Zubris and Brian, 2005;Browne et al 2011;Mason et al 2016;Steinmetz et al 2016Steinmetz et al , 2016De Souza Machado et al 2017;Horton et al 2017;Weithmann et al 2018) and contamination of surface and groundwater (Heberer 2002; Barnes et al 2008;Díaz-Cruz et al, 2008;Loos et al 2010;Faure et al 2012;Eriksen et al 2013;Eerkes-Medrano et al 2015;Zentner et al 2015). Unfortunately, validated and standardised analytical methods providing reproducible and internationally comparable data are often lacking.…”

Whereas the dramatic environmental impact of plastic waste rightfully receives considerable attention by scientists, policy makers and public in general, the human health impact of microand nanoplastics contamination of our food and beverages remains largely unknown. Indeed, most studies aim at understanding the environmental impact rather than the human health impact of a possible exposure to micro-and nanoplastics. In addition, these papers generally lack a methodological, standardised approach. Furthermore, some studies focus on the damage to and contamination level of animal species collected from the wild environment, and others investigate the rate and biology of microplastic uptake of animals fed with microplastics in laboratory. This review aims at understanding human exposure. Since there is, with few exceptions, no evidence available on the presence of micro-and nanoplastics in a normal diet, this study takes an indirect approach and analyses peer-reviewed publications since 2010 that document the presence of micro-and nanoplastics in those animals (more than 200 species) and food products that are part of the human food chain and that may thus contribute directly or indirectly to the uptake of micro-and nanoplastics via the human diet. It also addresses the question of the definitions, the methodologies and the quality criteria applied to obtain the reported results. This review suggests that, beyond a few estimations and comparisons, precise data to assess the exact exposure of humans to micro-and nanoplastics through their diet cannot be produced until standardised methods and definitions are available.

“…Shortage in water resources and rainfall in semiarid and arid zones, and the need for freshwater resources for the urban sector lead to the use of low‐quality water (e.g., treated waste water (TWW)) for irrigation. Because of the ionic concentration and composition of the TWW, its long‐term use for irrigation may have adverse influence on soil hydraulic properties (e.g., Coppola et al, ; Lado et al, ), on agricultural production (e.g., Rusan et al, ; Zavadil, ), and on environmental quality (e.g., Russo et al, ; Schoups et al, ; Zentner et al, ).…”

The main goal of this study was to test the capability of irrigation water‐based and soil‐based approaches to control nitrate and chloride mass fluxes and concentrations below the root zone of agricultural fields irrigated with treated waste water (TWW). Using numerical simulations of flow and transport in relatively a fine‐textured, unsaturated, spatially heterogeneous, flow domain, scenarios examined include: (i) irrigating with TWW only (REF); (ii) irrigation water is substituted between TWW and desalinized water (ADW); (iii) soil includes a capillary barrier (CB) and irrigating with TWW only (CB + TWW); and (iv) combination of (ii) and a CB (CB + ADW). Considering groundwater quality protection, plausible goals are: (i) to minimize solute discharges leaving the root zone, and, (ii) to maximize the probability that solute concentrations leaving the root zone will not exceed a prescribed, critical value. Results of the analyses suggest that in the case of a seasonal crop (a corn field) subject to irrigations only, with respect to the first goal, the CB + TWW and CB + ADW scenarios provide similar, excellent results, better than the ADW scenario; with respect to the second goal, however, the CB + ADW scenario gave substantially better results than the CB + TWW scenario. In the case a multiyear, perennial crop (a citrus orchard), subject to a sequence of irrigation and rainfall periods, for both solutes, and, particularly, nitrate, with respect to the two goals, both the ADW and CB + ADW scenarios perform better than the CB + TWW scenario. As compared with the REF and CB + TWW scenarios, the ADW and CB + ADW scenarios substantially reduce nitrogen mass fluxes to the groundwater and to the atmosphere, and, essentially, did not reduce nitrogen mass fluxes to the trees. Similar results, even better, were demonstrated for a relatively coarse‐textured, spatially heterogeneous soil.
