“…Also, the absorption and toxicity of pesticides in the body may be exacerbated with the increment of heat stress and core body temperature ( Gordon et al, 2014 ). As discovered in our previous pilot study on this farm, the high levels of pesticide metabolites in urine were correlated with heat stress and body temperature ( López-Gálvez et al, 2020 ), which can potentially affect kidney function. Further research should be conducted in the interaction of heat and pesticides in relation to kidney functioning.…”

“…We found that nearly all MSFWs reported working in extreme heat, most had core body temperatures reaching and exceeding 38 °C at some point during the workday, and all workers were dehydrated to some degree ( Wagoner et al, 2020 ). Also, many had high levels of organophosphate (OPs), pyrethroids (PYRs), and imidacloprid biomarkers in their urine; the highest pesticide levels were found during the summer, late in the harvest season ( Lopez-Galvez et al, 2018 ; López-Gálvez et al, 2020 ). Although the MSFWs are exposed to occupational risk factors such as heat and pesticides, to our knowledge, no studies have comprehensively examined, longitudinally, the potential effect of these combined occupational factors on kidney function in MSFWs.…”

Chronic kidney disease of unknown etiology (CKDu) is an epidemic that affects young agricultural workers in several warm regions of the world. However, there is a lack of monitoring of kidney issues in regions with extremely warm environments such as the Northwest of Mexico, a semi-arid region with a growing agricultural industry, where migrant and seasonal farm workers (MSFWs) travel to work in the fields. The objective of this study was to longitudinally assess kidney functioning of MSFWs in relation to pesticide exposure, heat stress and dehydration in a large-scale farm in Mexico. We enrolled 101 MSFWs, of whom 50 were randomly selected to work in an organic certified area and 51 were randomly selected to work in a conventional area. We also enrolled 50 office workers within the same region as a reference group. We collected urine and blood samples from all workers in addition to demographic, behavioral, and occupational characteristics. The physiological strain index (PSI) was used to estimate workers’ heat strain. Sampling was conducted at pre-harvest (March) and late in the harvest (July). Linear mixed models were built with the estimated glomerular filtration rate (eGFR) as the dependent variable. We found a significant decrease in kidney function in MSFWs compared to office workers. By the late harvest, one MSFW developed kidney disease, two MSFWs suffered a kidney injury, and 14 MSFWs were at risk of a kidney injury. We found that the eGFR in MSFWs decreased significantly from pre-harvest (125 ± 13.0 mL/min/1.73 m 2 ) to late harvest (109 ± 13.6 mL/min/1.73 m 2 ) (p < 0.001), while no significant change was observed in office workers. The eGFR was significantly lower in MSFWs who worked in the conventional field (101.2 ± 19.4 mL/min/1.73 m 2 ) vs the organic field (110.9 ± 13.6 mL/min/1.73 m 2 ) (p = 0.002). In our final model, we found that dehydration was associated with the decrease of eGFR. We also found an interaction between heat strain and job category, as a significant decline in eGFR by job category (conventional/organic MSFWs and office workers) was related to an increase in heat strain. This suggests that pesticide exposure needs to be considered in combination with heat stress and dehydration. This study provides valuable information on kidney function in MSFWs, and it shows the importance of early long-term monitoring in farm workers in other regions where CKDu has not been evaluated yet.

The exposure of operators, workers, residents and bystanders to pesticides is of high potential concern. Yet, reports on pesticide residues in the environment and near treated fields often spark debates if such findings might indicate a health risk. Although the underlying models are considered conservative, there are only limited field data on systemic exposure available. As a first step to improve the situation, we conducted a scoping review of state-of-the-art pesticide exposure biomonitoring studies in operators, workers, residents or bystanders. In contrast to existing reviews, we focused on target cultures of potential high pesticide exposure such as tree-grown produce, vine or hops. The search was conducted in Web of Science, Scopus and PubMed. Out of 17 eligible articles, a total of 11 studies met our search criteria, and 6 of them quantified the systemic exposure of humans. The analysis revealed that exposure was mainly driven by application of pesticides and reentry work, resulting in a higher exposure of operators and workers than of residents and bystanders. In nearly all cases, the systemic exposure was below the relevant toxicological reference values. The studies were subsequently analyzed to identify key criteria for a reliable design of a biomonitoring study on pesticide exposure.

“…However, several studies have shown that the use of neonicotinoid insecticides, such as imidacloprid, is a key factor for declining biodiversity of non‐target terrestrial insects [2–5] . In addition, imidacloprid residues affect soil properties, [6] soil organisms, [7–9] and take a threat to human health [10] . Imidacloprid is highly soluble in water, and there is a high possibility of it to enter into aquatic ecosystems through runoff, and thus potentially may pose risks to aquatic organisms, [11–12] such as dropping the survival of invertebrates, [13] inducing cyanobacteria blooms [14] and so on.…”

The photocatalytic composites based on BiVO4, TiO2 nanotubes (TNT) and reduced graphene oxide (RGO) were synthesized by a one‐step hydrothermal synthesis method. The properties and structures of the samples were characterized by SEM, XRD, UV‐Vis DRS, Raman spectroscopy, photoluminescence spectroscopy and XPS. The effects of RGO‐TNT loading, pH, and dosage of catalysts on degradation efficiency were tested. The best removal results were occured on the condition that loading amount of RGO‐TNT was 10 %, solution pH 10, and catalyst dosage was 1.4 g L−1. The obtained ternary composite with 10 wt% RGO‐TNT exhibited a significant enhancement in photocatalytic efficiency due to the lower band gap with enhanced light absorption and a suppression in the recombination rates of the photogenerated charge carriers, and about 73 % of imidacloprid was degraded within 30 min under UV irradiation. Furthermore, BiVO4/RGO‐TNT‐10 can be reused for 6 times without obvious catalysis loss. Trapping experiments showed that hydroxyl radicals were the main active species in the imidacloprid photocatalytic degradation, and a possible photocatalytic mechanism was proposed based on the results of trapping experiments.
