“…In the case of diuron, the obtained RQ values are in good agreement with those given in the specialist literature. In publications concerning European rivers, the RQ values observed for diuron was below or equal to 1 (Deng et al 2012;Palma et al 2014;Tsaboula et al 2016;Tousova et al 2017;Carazo-Rojas et al 2018;Shao et al 2019) which means no adverse effects due to the presence of this biocide in water. A similar situation occurs in reference to terbutryn-the RQ value obtained in this work is reflected in other authors' research The RQs have been found in the literature as no more than 0.1 (Tsaboula et al 2016;Tousova et al 2017;Gallé et al 2019).…”

The EU directive 2013/39/EU has incorporated four biocidal compounds as priority substances: diuron, isoproturon, cybutryne, and terbutryn. The research was undertaken to determine the concentration of biocides in surface waters in three locations in southern Poland: the Wisła River in Kraków, the Wisłoka River in Mielec, and the drainage ditch draining water from arable fields located near Mielec. Environmental samples were taken in two series: winter (February) and spring (May and June). The analyses were carried out using gas chromatography with mass spectrometry. The seasonality of biocides in surface waters was observed. In winter samples, the concentrations were below MQL, while in spring, they ranged from a few to several dozen nanograms per liter. The highest concentrations of all analyzed compounds were recorded in water taken from the Wisła River. According to directive 2013/39/EU, the maximum allowable concentration was exceeded only in the case of cybutryne in water from the Wisła, both in May and in June. The assessment of the toxicity with the tested compounds was defined based on the Environmental Risk Assessment method. Low risk was estimated for diuron and isoproturon, while moderate risk for terbutryn and cybutryne.

“…A notable exception comes from a study conducted in Costa Rica ( Carazo-Rojas et al., 2018 ), where crop growing seasons and pesticide application extend throughout the year. In this case, pesticide application patterns were not a good predictor of aquatic pesticide concentrations.…”

A review of long-term pesticide monitoring studies to assess surface water quality trends

Aquatic pesticide pollution from both agricultural and urban pest control is a concern in many parts of the world. Making an accurate assessment of pesticide exposure is the starting point to protecting aquatic ecosystems. This in turn requires the design of an effective monitoring program. Monitoring is also essential to evaluate the efficacy of mitigation measures aimed to curb pesticide pollution. However, empirical evidence for their efficacy can be confounded by additional influencing factors, most prominently variable weather conditions. This review summarizes the experiences gained from long-term (>5 years) pesticide monitoring studies for detecting trends and provides recommendations for their improvement. We reviewed articles published in the scientific literature, with a few complements from selected grey literature, for a total of 20 studies which fulfill our search criteria. Overall, temporal trends of pesticide use and hydrological conditions were the two most common factors influencing aquatic pesticide pollution. Eighteen studies demonstrated observable effects to surface water concentrations from changes in pesticide application rates (e.g., use restriction) and sixteen studies from interannual variability in hydrological conditions during the application period. Accounting for seasonal- and streamflow-related variability in trend analysis is important because the two factors can obscure trends caused by changes in pesticide use or management practices. Other mitigation measures (e.g., buffer strips) were only detectable in four studies where concentrations or loads were reduced by > 45%. Collecting additional agricultural (e.g., pesticide use, mitigation measures) and environmental (e.g., precipitation, stream flow) data, as well as establishing a baseline before the implementation of mitigation measures have been consistently reported as prerequisites to interpret water quality trends from long-term monitoring studies, but have rarely been implemented in the past.

“…Due to the threat that pesticides as Chlorpyrifos pose to the ecosystems, and owing to the growing public awareness on the need of protecting both ecosystems and human health from the risks related to chemical pollution (Kuzmanović et al, 2015). There is an increasing need to intensify the environmental monitoring data and Ecotoxicological Risk Assessment(ERA) (Carazo-Rojas et al, 2018). Recently, many monitoring programs and scientific studies have put more focus on the occurrence, distribution and fate of pesticides and their potential environmental effects in individual rivers, reservoirs and lakes (Chen et al, 2018).…”

Chlorpyrifos is a commonly used pesticide that belong to the organophosphorus pesticides (OPPs) group. Chlorpyrifos is widely used in residential environments and agriculture for pest control. As many OPPs, Chlorpyrifos degrades faster to more complex and toxic compounds under natural conditions, thus diverse effects of these compounds over aquatic species are unknown. Due to the risk that pesticides as Chlorpyrifos, which mainly breaks down to 3,5,6- trichloro-2-pyridinol (TCP) on the ecosystems, there is an increasing need to intensify the environmental monitoring and ecotoxicological risk assessment for both substances. Risk assessment provides a systematic approach for characterizing the nature and magnitude of the risks associated with environmental health hazards. However, in countries like Colombia, where the use of Chlorpyrifos is widespread, the number of investigations on the dynamics and risk involved in the presence of this class of substances in water bodies is limited.
