Development of a QuEChERS-based method for the analysis of pharmaceuticals and personal care products in lettuces grown in field-scale agricultural plots irrigated with reclaimed water

Oak wood provides suitable nutrients for long-term continuous pesticides removal by Trametes versicolor in a pilot plant trickle bed reactor

“…Regarding soil composition and irrigation system, the E. coli levels found in lettuces (Table 3) suggest that C soil and sprinkling irrigation favor the accumulation of E. coli in the lettuces. According to the previous determination of PPCPs in lettuces [48], concentration values were much lower in crops irrigated with B water. But the other variables (soil composition and irrigation system) also appeared to impact the final concentrations of CECs in the plant, being C soils and sprinkling irrigation, the ones leading to a lower CECs' uptake by lettuces.…”

“…The determination of CECs in the lettuces and soils was performed following the developed QuEChERS-based method by Sunyer-Caldú and Diaz-Cruz, [48]. Briefly, this method consists of a first extraction step of 1 g dw lettuce using QuEChERS kits (citrate and PSA-Kit-02 kits).…”

“…The occurrence of PPCPs in the lettuces was discussed together with the description of the analytical method developed for their analysis in Sunyer-Caldú and Diaz-Cruz, [48]. In the present work, we focus on soil and water, however, to have the full picture, the concentrations of the PPCPs determined in the lettuces are listed in Table S4.…”

Beach showers as sources of contamination for sunscreen pollution in marine protected areas and areas of intensive beach tourism in Hawaii, USA

“…A recently recognized source of sunscreen petrochemical pollution is found associated with agriculture; reclaimed water from wastewater treatment effluent and sludge biosolids are used in irrigated agriculture and as soil/fertilizer amendments to commercial agricultural settings (Plagellat et al, 2006;Zhang et al, 2011;Eljarrat et al, 2012;Jurado et al, 2014;Sunyer-Caldú and Diaz-Cruz, 2021;Cadena-Aizaga et al, 2022). This point-source of pollution can have adverse impacts to crop yields, contaminate crops with these petrochemical UV-filters, and be associated with agricultural runoff within a watershed, ultimately discharging into groundwater, and freshwater and marine receiving-waters (Loraine and Pettigrove, 2006;Molins-Delgado et al, 2016;Serra-Roig et al, 2016;Cabrera-Peralta and Pena-Alvarez, 2018;Glover et al, 2021;Ramos et al, 2021;Bigott et al, 2022).…”

Optimization method for quantification of sunscreen organic ultraviolet filters in coastal sands

“…Recently, the focus of contamination has been on coral reefs, but these chemicals are found in marine and aquatic environments, including Arctic and Antarctic coastlines, rivers, and lake systems worldwide, as well as potable water sources. Water and sediment contamination is the most commonly screened sample matrix, but contaminated biological matrices include corals, subsistence fish, migratory birds and their eggs, sea turtle, marine mammals, vegetable produce (e.g., lettuce, tomato, and cucumber), and marine algae [2][3][4][5][6][7].…”
