“…Atrazine, DEA, DIA, simazine, propazine, terbuthylazine and DET have also been detected in water samples from the Turia river basin (Ccanccapa et al, 2016a). In other European countries, triazines have frequently been detected in groundwater (atrazine, DEA and DIA) (Vryzas et al, 2012) and in surface waters (atrazine, DEA and simazine) (Thomatou et al, 2013) in Greece, in most of the tap water samples collected around Paris in France (atrazine, DEA and DIA, simazine, propazine, terbuthylazine and DET) (Cotton et al, 2016), and in drinking and groundwaters (atrazine, terbuthylazine, DEA, DIA and DET) around Zagreb in Croatia (Fingler et al, 2017).…”

“…Their application in the environment may contaminate water resources, especially those located in intensive agricultural areas (Menezes Filho et al, 2010). An increasing number of herbicides, insecticides and fungicides have been detected in different watercourses (Masiá et al, 2015;Cotton et al, 2016;Rousis et al, 2017), some of which are destined for human consumption, so the protection of water quality has now become subject to more stringent legislation. The European Union has introduced strict directives to protect water quality, such as the REACH Regulation (EC, 2006) concerning the Registration, Evaluation, Authorization and Restriction of Chemicals, while Directive 2008/105/EC, on environmental quality standards in the field of water policy, provides a detail of priority substances (33) to be controlled in water, with pesticides making up a third of the list (EC, 2008).…”

Pesticides are needed to maintain high production in the vineyard area of La Rioja (Spain), and monitoring their spatial distribution is a priority for preserving the quality of natural resources. Accordingly, the purpose of this work was to conduct a study to evaluate the presence and seasonal distribution of herbicide and insecticide residues in ground and surface waters in this region. The monitoring network comprised 12 surface waters and 78 groundwaters, covering the three subareas (63,593ha) into which the vineyard region is divided. The quality of natural waters was examined through the analysis of twenty-two herbicides, eight of their main degradation products, and eight insecticides. Pesticides were extracted by solid-phase extraction, and analysed by gas chromatography-mass spectrometry or by liquid-chromatography-mass spectrometry. The results reveal the presence of most of the herbicides and insecticides included in the study in one or more of the samples collected during the four campaigns. The herbicide terbuthylazine and its metabolite desethylterbuthylazine were the compounds more frequently detected (present in >65% of the samples across all the campaigns). Other compounds detected in >50% of the samples in one sampling campaign were the herbicides fluometuron, metolachlor, alachlor and ethofumesate. Insecticides were present in a small number of samples, with only pirimicarb being detected in >25% of the samples in March and June campaigns. The results reveal that the sum of compounds detected (mainly herbicides) was higher than 0.5μgL in >50% of the samples, especially in the campaigns with the highest application of these compounds. A possible recovery of the quality of the waters was detected outside the periods of crop cultivation, although more monitoring programmes are needed to confirm this trend with a view to preventing and/or maintaining the sustainability of natural resources.

“…Treatment technologies commonly applied in the process of drinking water production have been shown to result in only partial removal of TBA (Ormad et al 2008). The herbicide and its metabolite DET have frequently been detected in tap water samples collected in France (Cotton et al 2016), Croatia (Fingler et al 2017) and other European countries (HerreroHernandez et al 2017). Recent occurrence, and mobility, of TBA and DET in European waters are summarised in this review.…”

Terbuthylazine and desethylterbuthylazine: Recent occurrence, mobility and removal techniques

2018

View full text Add to dashboard Cite

The herbicide terbuthylazine (TBA) has displaced atrazine in most of EU countries, becoming one of the most regularly used pesticides and, therefore, frequently detected in natural waters. The affinity of TBA for soil organic matter suggests prolonged contamination; degradation leads to the release of the metabolite desethylterbuthylazine (DET), which has higher water solubility and binds more weakly to organic matter compared to the parent compound, resulting in higher associated risk for contamination of groundwater resources. Additionally, TBA and DET are chemicals of emerging concern because of their persistence and toxicity towards aquatic organisms; moreover, they are known to have significant endocrine disruption capacity to wildlife and humans. Conventional treatments applied during drinking water production do not lead to the complete removal of these chemicals; activated carbon provides the greatest efficiency, whereas ozonation can generate by-products with comparable oestrogenic activity to atrazine. Hydrogen peroxide alone is ineffective to degrade TBA, while UV/HO advanced oxidation and photocatalysis are the most effective processes for oxidation of TBA. It has been determined that direct photolysis gives the highest degradation efficiency of all UV/HO treatments, while most of the photocatalytic degradation is attributed to OH radicals, and TiO solar-photocatalytic ozonation can lead to almost complete TBA removal in ∼30 min. Constructed wetlands provide a valuable buffer capacity, protecting downstream surface waters from contaminated runoff. TBA and DET occurrence are summarized and removal techniques are critically evaluated and compared, to provide the reader with a comprehensive guide to state-of-the-art TBA removal and potential future treatments.

“…A multiresidue screening method for mixtures of pesticides and drugs was published by Cotton et al (2016) to quickly characterize contaminant concentrations in water. The fully automated method utilizes solid phase extraction (SPE) and ultrahigh pressure liquid chromatography (UHPLC) with high resolution mass spectrometry (HRMS) to measure over 500 different analytes at detection limits ranging between 0.1 and 1,000 ng L −1 .…”

A total of 79 papers published in 2016 were reviewed ranging from detailed descriptions of analytical methods, to fate and occurrence studies, to ecological effects and sampling techniques for a wide variety of emerging contaminants likely to occur in agricultural environments. New methods and studies on veterinary pharmaceuticals, steroids, antibiotic resistance genes, cyanotoxins, and potential effects of biochar use in agricultural environments continue to expand our knowledge base on the occurrence and potential impacts of these compounds. This review is divided into the following sections: Introduction, Analytical Methods, Steroid Hormones, Anthelmintics, Antibiotic Fate and Occurrence, Antibiotic Resistance Genes, Cyanotoxins, and Implications of Biochar in Agricultural Environments.
