“…The nutrient concentrations in simulated wastewater were low, and the systems were not limited by oxygen availability. 14 In previous studies, El-Khateeb et al 23,24,47 combined constructed wetlands with wastewater treatment technology to achieve wastewater treatment efficiency and improve effluent quality. However, from the perspective of the treatment efficiency of constructed wetlands, that of ordinary constructed wetlands is lower than that of constructed wetlands that were modied with Fe.…”

“…13 For this reason, the occurrence of PPCPs and pesticides in the aquatic environment has become a worldwide issue of increasing environmental concern. 14 In nature, organic micropollutants (OMPs) have increasingly emerged in the environment. 15 For example, pharmaceutical residues and endocrine disrupting compounds are subjected to a series of complex degradative processes, but some of them remain in soil and water owing to their stability.…”

“…The redox potential or the pH could influence the storage of this pesticide in the sediments [13], [22]. The lower concentrations of tebuconazol in the other samples could be also explained by its high rate of biodegradation by plants [23]. These observations were the reverse for boscalid and metolachlor ( Figure 3A).…”

Currently, pesticides massively used in agricultural areas end up in watercourses, since they are usually final receptacles of organic contamination. A large number of ponds occurred in agricultural catchments, but their role regarding pesticides behaviour, is still poorly investigated. The Pestipond project aims to fill this gap, particularly considering the Bassioué pond, which is located in the carbonated agricultural upper sub-catchment of the Auradé critical zone observatory (Gers, France), with a wheat/sunflower crop rotation and a steep slope. Our current objective was to understand (i) how and where pesticides are stored in the sediments, and (ii) the relationship with the characteristics of sediments, supposed to be highly involved in the storage and degradation of pesticides. A regular quadrat of cores (#20cm) was sampled at autumn 2019 and summer 2020. A set of pesticide molecules was quantified as well as sediment texture, and organic carbon and nitrogen content. The results highlighted that sediment texture varied between upstream and downstream of the pond, as did the spatial distribution of pesticides, which was partly controlled by their physicochemical properties. More hydrophilic pesticides had more affinity with the finest fractions of the sediments. This study also highlights the difference in storage of these molecules according to depth. In particular, boscalid (logKOW=3) was found in greater quantities in the deepest samples, in relation with increasing coarse silt content. Finally, a seasonal effect is also observed on pesticide levels. This work provides new knowledge on the role of ponds in pesticide storage, dissipation and transfer downstream.

“…Ayrıca pestisitlerin yeraltı suyuna sızma potansiyellerine bakılmış, chlorpyrifos, fenthion ve dichlorvos bu açıdan daha az tehlikeli görülürken, diazinon'ın yeraltı suyuna geçme potansiyelinin yüksek olduğu belirtilmiştir. Benzer şekilde bitkilendirilmemiş ve farklı bitkiler kullanılmış yapay sulak alan uygulamalarının verimini labaratuvar ölçeğinde araştıran bir çalışmada, pestisitlerin giderimi için mekanizmaların biyodegredasyon ve bitki içinde metabolizasyon aşamaları olduğu tespit edilmiştir [86].…”

Pestisitler, yeterli miktarda ve kalitede tarımsal üretim gerçekleştirmek için modern tarımının vazgeçilmezi olmuşlardır. Kontrolsüz ve aşırı pestisit kullanımı, doğal kaynaklar, insanlar ve diğer canlılar için tehlike oluşturmaktadır. Özellikle su kaynaklarındaki pestisit kirliliğinin kontrolü için, pestisit kullanım ve satışına dair verilerin sağlıklı tutulması, pestisit uygulaması birlikte pestisitlerin taşınım ve dönüşüm mekanizmalarının bilinmesi, izleme çalışmaları ile pestisit varlığının tespit edilmesi gerekmektedir. Matematiksel modeller vasıtası ile de pestisit kirliğinin yönetiminde zaman ve ekonomik açıdan tasarruf sağlanabilecektir. Ayrıca En İyi Yönetim Uygulamaları (EİYU) gibi doğal arıtım yöntemlerinin ve alternatif kontrol tedbirlerinin havzada uygulanabilirliği araştıralabilecektir. Bazı çalışmalarda EİYU kapsamında uygulanan bitkilendirilmiş filtre şeritler ile su kaynaklarında %40 üzerinde pestisit giderimi sağlandığı görülmüştür. EİYU'ların verimliliğini araştırmak için karar destek sistemleri (KDS) önemli bir araç olup, pestisit türlerine ve havza yapısına göre giderim oranları değişmektedir. Bir metre uzunluğundaki bir bitkilendirilmiş şerit uygulamasının etkinliğini KDS ile ölçen bir çalışmada Kaliforniya'daki domates tarlalarında %40-60 oranında pestisit giderimi sağlanırken aynı uygulama Oregon'daki buğday tarlalarında %15-20 oranında giderim sağlamaktadır. Bu tarz çalışmaların ulusal düzeyde artması ile yoğun pestisit kullanımı olan tarımsal havzalarda pestisit kirliliğinin kontrolü kolaylaşacak, alınabilecek tedbirler kolayca belirlenebilecektir. Pesticide use is essential for sufficient quality and quantity production in modern agriculture. Uncontrolled and excessive pesticide use poses serious danger for human health, other living things and natural resources. It is necessary to keep track of pesticide sale and consumption data, to determine pesticide fate and transport mechanisms in the environment after application and monitoring pesticides in water sources for sustain efficient pesticide pollution control. Mathematical models are useful for the pesticide pollution control by time and money saving. It will also possible to investigate the applicability of natural treatment and alternative control methods in the basins such as Best Management Practices (BMP). As mentioned in this study, vegetated filter strip application as BMP reduces pesticide load over 40% in water sources. Decision Support Systems (DSS) are promising tool for assess the efficiency of BMPs. DSS are able to predict pesticide concentrations in the watershed that depends on pesticide types and watershed properties. In a DSS study, 1 meter vegetated filter strip application in tomato fields removes 40-60% pesticide concentration in receiving water bodies while reduces 15-20% pesticide pollution in the wheat fields in Oregon. With the increase of such studies at the national level, the control of pesticide pollution in agricultural basins with intensive pesticide use will be easier.
