“…Furthermore, runoff and flooding also contribute to the unintentional diffusion and non-target contamination of pesticides [ 14 , 15 ]. Globally, varying levels of pesticides, as documented by Cech et al [ 16 ], Panis et al [ 17 ], Peris et al [ 18 ], Sun et al [ 19 ], and Vickneswaran et al [ 20 ], pose threats to both human health and the environment.…”

This study delved into the impact of open biomass burning on the distribution of pesticide and polycyclic aromatic hydrocarbon (PAH) residues across soil, rice straw, total suspended particulates (TSP), particulate matter with aerodynamic diameter ≤ 10 µm (PM10), and aerosols. A combination of herbicides atrazine (ATZ) and diuron (DIU), fungicide carbendazim (CBD), and insecticide chlorpyriphos (CPF) was applied to biomass before burning. Post-burning, the primary soil pesticide shifted from propyzamide (67.6%) to chlorpyriphos (94.8%). Raw straw biomass retained residues from all pesticide groups, with chlorpyriphos notably dominating (79.7%). Ash residue analysis unveiled significant alterations, with elevated concentrations of chlorpyriphos and terbuthylazine, alongside the emergence of atrazine-desethyl and triadimenol. Pre-burning TSP analysis identified 15 pesticides, with linuron as the primary compound (51.8%). Post-burning, all 21 pesticides were detected, showing significant increases in metobromuron, atrazine-desethyl, and cyanazine concentrations. PM10 composition mirrored TSP but exhibited additional compounds and heightened concentrations, particularly for atrazine, linuron, and cyanazine. Aerosol analysis post-burning indicated a substantial 39.2-fold increase in atrazine concentration, accompanied by the presence of sebuthylazine, formothion, and propyzamide. Carcinogenic PAHs exhibited noteworthy post-burning increases, contributing around 90.1 and 86.9% of all detected PAHs in TSP and PM10, respectively. These insights advance understanding of pesticide dynamics in burning processes, crucial for implementing sustainable agricultural practices and safeguarding environmental and human health.

“…It is known that approximately 99.9% of applied pesticides are transported to nontarget areas by evaporation, spray drift, surface runoff, degradation, adsorption, and leaching processes, and only 0.1% of applied pesticides reach the intended target pest [7,8]. Precipitation and agricultural irrigation transport pesticides from the areas where they are applied to receiving water bodies (WBs) [9,10].…”

In this study, current pesticide use was determined on the basis of active substances (ASs) in each water body in the Marmara Basin, which is the most crowded region of Türkiye and where agriculture is intensive. The risks of detected pesticide ASs were then categorized in terms of usage amount, water body monitoring results, and hazardous characteristics. At the same time, a system was proposed for determining pesticide use on an AS basis, based on the product planted in districts that do not have detailed information on AS use. Finally, a methodology for assessing pesticide pressure on water bodies was developed by utilizing pesticide risk based on the determined AS types under data scarcity conditions. The topic undertaken is current and extremely important in the era of food safety, and is related to growing pressure on water, on one hand, and human health and quality of food products, on the other. Data based on ASs are hard to record and store, particularly in developing countries; therefore, a data inventory was initially realized in the study as an essential step towards an assessment procedure. The easy-to-use pesticide pressure determination methodology was developed and applied to the Marmara Basin of Türkiye, ensuring compliance with the Water framework Directive (WFD) and EU Green Deal. Constraints experienced during the application of the developed methodology are put forth with the intention of providing utilizable information to those international scientists who will be interested in practicing it in the future. Therefore, transposition of the methodology to other basins in different countries will be possible. According to 2021 data, 0.04–8.83 kg/ha pesticide and 173 pesticide active substances were used in the basin. ASs were prioritized over four criteria based on the amount of use, hazardous properties, and monitoring results. Consequently, 52 active substances were determined and included in the risk group. Taking these criteria into consideration, all the 276 agricultural water bodies in the basin were revealed to be under pesticide pressure.

With considerable concerns about the associations between metabolic disorders and agricultural biocides, there are scattered data suggesting that the triazole fungicide prothioconazole (PTC) at lower doses than the no observed adverse effect level of 5000 μg/kg/d possibly has the potential to disrupt glycolipid metabolism in mammals. Here, we investigated the effects of 50, 500, and 5000 μg/kg/ d of PTC on glycolipid metabolism in mice following 8 weeks of administration via drinking water, with specific attention on brown adipose tissue (BAT) and white adipose tissue (WAT) in addition to the liver. We found that along with the increased serum triglyceride level in the 5000 μg/kg/d group, small fatty vacuoles occurred in livers in all treatment groups, indicating lipid accumulation. No change in WAT was observed, but PTC caused BAT whitening, characterized by adipocyte hypertrophy, more unilocular adipocytes with enlarged lipid droplets, reduced UCP1 levels, and down-regulated Doi2 expression, and even the dose of 50 μg/kg/d was effective. Transcriptomic analysis revealed immune inhibition and circadian rhythm disturbance in BAT from the 5000 μg/kg/d group, which are in agreement with BAT whitening and inactivation. On employing the C3H10T1/2 cells in vitro, we found that PTC treatment concentration-dependently promoted lipid accumulation in brown adipocytes, along with altered expression of thermogenesis-related and circadian genes. Taken together, our study shows that low doses of PTC caused BAT whitening, calling for much attention to the new target by pollutants.
