“…DCF was almost completely disappeared in aerobic slurry regardless of the origins of the soils after 14 days of incubation. The high degradability of DCF in this study was quite different behavior from that in aerobic wastewater treatment where DCF is persistent in general [16,[27][28][29][30]. IBP and FEP were also degraded completely regardless of the origin of soils under aerobic condition, although several metabolites of IBP have been well known in biological degradation [31].…”

“…A study on the degradation of pharmaceuticals in four US agricultural soils reported half-life times of 1-20 days for ibuprofen, naproxen, and diclofenac [15]. The removal of NSAIDs in reed beds for sludge treatment was reported to be high, although complete separation of removal into adsorption, biodegradation and transformation to other compounds was difficult [16]. The fate of NSAIDs in plants and crops after taking up pharmaceuticals from reclaimed water and sewage sludge have been actively investigated [17].…”

One of the concerns against the use of sewage sludge for agricultural purposes is emerging contaminants contained in sewage sludge. Most of the studies on biological degradation of pharmaceutically active compounds in agricultural land were carried out with water-unsaturated soils under relatively aerobic conditions. In this study, the degradation of pharmaceuticals mainly including non-steroidal anti-inflammatory drugs (NSAIDs) was investigated in Asian rice paddy soils that are flooded in anaerobic condition. The experimental results showed that the concentrations of the target pharmaceuticals excluding the exception of naproxen were poorly decreased in anaerobic condition. On the other hand, the microbial communities of the soils contained the aerobic degraders of clofibric acid and diclofenac, which are generally persistent in biological wastewater treatment. The higher degradation rates in aerobic condition suggest the possibility of enhanced degradation of pharmaceuticals by supplying oxygen with plowing anaerobic rice fields or with drying the field in off-season for farming.

“…38,39 PCT is easily degraded under aerobic conditions 40 and readily eliminated in WWTPs, with high removal percentages. [41][42][43][44] The in silico biodegradability predictions showed that PCT and its TPs were biodegradable compounds. This could be explained by the presence of the amide functional group, which facilitates enzymatic hydrolysis.…”

Diklofenak, insan ve veterinerlik amaçlı yaygın kullanılan ilaçlardan biri olmuştur. Diklofenak'ın çevre ve organizmalar üzerindeki olumsuz etkilerinin ortaya çıkmasıyla, araştırma çalışmaları atıksudan uzaklaştırılmasına yönelmiştir. Atıksu ya da yüzeysel suda mikrogram düzeyindeki derişimlerine rağmen, endokrin sistemini bozabilir, bu da üst düzey organizmaların metabolizmasında dolayısıyla ekosistemde sorunlara yol açabilir. Bu nedenle diklofenakın tüketiminden başlayarak etkin diklofenak arıtımına, deşarj standartlarının belirlenmesine ve su yaşamının üst düzeyde korunmasına kadar uzanan bir yelpazede diklofenak kontrolü için acil önlemler alınmalıdır. Diklofenak ile ilgili diğer bir problem ise, fotoliz ve biyolojik reaksiyonları ile oluşan bozunma ürünlerinin atıksu arıtma tesislerinin çıkışında bulunmasıdır. Bu dönüşüm ürünleri organizmalar için daha fazla tehdit oluşturmaktadır. Dolayısıyla, bu derleme makalesi diklofenakın çevre üzerindeki olumsuz etkilerini, birincil diklofenak kaynaklarını, hayvanlar üzerindeki endokrin bozucu etkilerini, insan vücudundaki metabolizmasını, arıtma yaklaşımlarını, biyolojik ve kimyasal bozunma metabolitlerinin türünü veya dönüşüm ürünlerini vurgulamayı amaçlamaktadır.Diclofenac has been one of the widely consumed pharmaceuticals for human and veterinary purposes. The research studies are devoted to investigating its removal from wastewater since its adverse effect on the environment and the organisms have been revealed. Despite its microgram level concentrations in the wastewater or water bodies, it could disrupt the endocrine system, which leads to problems in the metabolism of the higher-level organisms and, thereby, the ecosystem. Therefore, urgent measures should be taken to control diclofenac starting from its consumption and extending to the efficient diclofenac treatment, determination of discharge standards, or the high-level protection of aquatic life. Another problem with diclofenac is the degradation end-products that form through photolysis, or biological reactions remain in the wastewater treatment plants' effluent. These transformation products create further threats for the organisms. This review paper aims to emphasize the adverse effects of diclofenac on the environment, the primary diclofenac sources, its endocrine disrupting effects on the animals, metabolism in the human body, treatment approaches, type of biological and chemical degradation metabolites, or transformation products.
