Carbofuran is a carbamate pesticide, a broad-spectrum, high-efficiency, low-residue, and highly toxic insecticide, acaricide, and nematicide, widely used in agriculture. Carbofuran is most harmful to birds, and birds or insects killed by furan poisoning can be killed by secondary poisoning after being foraged by raptors, small mammals, or reptiles. In this paper, an UPLC-MS/MS method was developed for the determination of carbofuran and its metabolite, 3-hydroxycarbofuran, in duck liver. Liver tissue was first ground into a homogenate and then passed through ethyl acetate liquid-liquid extraction processing samples. Multiple reaction monitoring (MRM) mode was used for quantitative analysis, m/z 222.1 → 165.1 for carbofuran, m/z 238.1 → 180.9 for 3-hydroxycarbofuran and m/z 290.2 → 198.2 for an internal standard. The standard curves of carbofuran and 3-hydroxycarbofuran in duck liver were within a range of 2–2000 ng/g, where the linearity was good, the lower limit of quantification was 2 ng/g. The intra-day precision of carbofuran and 3-hydroxycarbofuran was <14%, and the inter-day precision was <13%, the accuracy range was between 91.8 and 108.9%, the average extraction efficiency was higher than 75.1% with a matrix effect between 93.4 and 107.7%. The developed method was applied to a situation of suspected duck poisoning at a local farm.

ÖZAromatik yapılı, çevresel koşullarda zorlukla parçalanabilen, kararlı organik kirleticilerin başında gelen pestisitler, atmosfere, su sistemlerine, besin zincirine taşınmakta, asıl kaynaklarından çok uzak noktalarda birikebilmektedir. Konvansiyonel arıtma proseslerinin pestisitlerin gideriminde yetersiz kalmasından dolayı kirletilmiş sulardan uzaklaştırılmaları için yeni arıtım teknolojilerine ihtiyaç duyulmaktadır. Son yıllarda, su sistemlerinden konvansiyonel tekniklerle arıtılamayan kirleticilerin giderilmesinde birleşik fotokatalitik-biyolojik arıtma umut verici bir alternatiftir: Fotokataliz toksik organikleri biyolojik olarak parçalanabilir ürünlere dönüştürürken, biyolojik parçalama ürünlerini verimli şekilde mineralize eder. Ön arıtma sırasında gereksiz kimyasal ve %60 oranında enerji sarfiyatından kaçınmak amacıyla ön arıtma basamağında mineralizasyon yüzdesi minimalize edilerek çalışma maliyeti düşürülür. Literatüre göre yalnız kimyasal prosesle yaklaşık %80 pestisit parçalanması ve %50'den az mineralizasyon gözlemlenebilirken hibrit reaktör sistemiyle tamamen parçalanma ve yaklaşık %90 pestisit mineralizasyonu elde edilebilmektedir. Bu derlemenin amacı, fotobiyokataliz işleminin, bireysel fotokataliz ve/veya biyolojik arıtma yöntemlerine göre pestisit giderim koşulları kapsamında, temellerini, mekanizmalarını ve literatürde yer alan güncel çalışmaları ele almak ve incelemektir. ABSTRACTPesticides, which are aromatic, hardly degradable under environmental conditions, leading to stable organic contaminants are transported to the atmosphere, water systems, food chain, and can accumulate at far distances from their original sources. Novel treatment technologies are required to eliminate pesticides from contaminated waters due to ineffectiveness of the conventional treatment processes for pesticide removals. In recent years, combined photocatalytic-biological degradation is a promising alternative to eliminate contaminants not treatable by conventional techniques from water systems: Photocatalysis converts toxic organics into biodegradable products, while biodegradation efficiently mineralizes the products. In order to avoid unnecessary chemical and 60% energy consumption during pre-treatment, the percentage mineralization in the pre-treatment step is minimized and the operating cost is reduced. According to the literature, while only about 80% pesticide degradation and less than 50% mineralization can be observed by the chemical process, a completely degradation and about 90% pesticide mineralization can be obtained with hybrid reactor system. The aim of this review is to ÖHÜ Müh. Bilim. Derg. / OHU J. Eng. Sci.8(2): 675-688 G. DOĞDU OKÇU, H. E. ÖKTEN, A. YALÇUK 676 evaluate handling and examining fundamentals, mechanisms and recent studies in the literature within scope of pesticide removal conditions accordance with individual photocatalysis and/or biological treatment methods.

“…Carbofuran has become one of the dominant insecticides used in agriculture due to its ability to control a wide range of pests [ 6 ]. However, carbofuran is known as a powerful inhibitor of acetyl-cholinesterase and possesses serious toxicity, producing negative health effects for wild animals and humans and poisoning rivers and groundwater [ 7 , 8 , 9 ]. In addition, the application of carbofuran to crops results in changes in the metabolism of plants and changes the soil microbiota and their metabolites [ 10 ], which ultimately affects crop quality [ 11 , 12 , 13 , 14 ].…”

Carbofuran is one of the most commonly used N-methylcarbamate-based pesticides and is excellent for controlling pests; however, carbofuran also causes soil and water pollution. Although various studies have been conducted on the bioremediation of pesticide-contaminated soil, the changes occurring in the metabolome during the bioremediation of carbofuran are not fully understood. In this study, the intracellular and extracellular metabolites of the Chryseobacterium sp. BSC2-3 strain were analysed during carbofuran degradation by using a liquid chromatography–mass spectrometry-based metabolomics approach. We found that the BSC2-3 strain extracellularly transformed carbofuran into 3-hydroxycarbofuran. Intracellular metabolite analysis revealed that carbofuran mainly affected aminobenzoate degradation, ubiquinone and terpenoid-quinone biosynthesis, and arginine and proline metabolism. Carbofuran especially affected the metabolic pathway for the degradation of naphthalene and aminobenzoate. Metabolomics additionally revealed that the strain produces disease resistance inducers and plant growth regulators. We also identified the genes involved in the production of indole-3-acetic acid, which is one of the most active auxins. Overall, we identified the metabolic changes induced in carbofuran-degrading bacteria and the genes predicted to be responsible for the degradation of carbofuran.
