Plants affect the dissipation and leaching of anilide pesticides in soil mesocosms: Insights from compound-specific isotope analysis (CSIA)

Simple extraction methods for pesticide compound-specific isotope analysis from environmental samples

“…S4 and S5, Table S5). These results confirm the applicability of SPE for both carbon and nitrogen CSIA of atrazine, acetochlor, S- metolachlor, metalaxyl, butachlor, and alachlor [ 3 , 5 , 6 , 8 , 10 , 15 ]. The findings also extend SPE methods for CSIA to the fungicides dimethomorph and tebuconazole.…”

“…Three types of water matrices were tested: (i) buffered (pH=7) ultrapure water (>18 MΩ cm), (ii) storm water from a vineyard catchment (Rouffach, France) [14] , (iii) runoff and river water from two different crop catchments (Alteckendorf and Souffel, France) [ 3 , 10 ]. Field samples were successively filtered at 11 µm trough grade one cellulose (Whatmann 1001-047) and 0.45 µm cellulose acetate membrane filters, and stored at 4°C until further analysis.…”

“…The top 0−10 cm of i) river sediments from the Souffel river, France, [14] , ii) vineyard soils from the Rouffach catchment [10] , iii) vineyard storm water sediments (Rouffach, France [14] ), iv) forest soils (Strengbach, France [10] ) were sampled with a shovel cleaned with ultrapure water and ethanol and wiped between collections. Soil and sediment samples were sieved through a 2-mm mesh and stored at 4°C before spiking.…”

“…Previously, solid-phase extraction (SPE) for pesticide extraction from water for CSIA has been tested for atrazine, acetochlor, S- metolachlor, metalaxyl, butachlor, alachlor, terbutryn, chlordizon, and several of their transformation products [5] , [6] , [7] , [8] . Pesticide extraction methods from soil, sediment and plants for reliable pesticide CSIA have been used in both laboratory and field studies [9] , [10] , [11] , [12] . Ivdra et al.…”

The Role of Ponds in Pesticide Dissipation at the Agricultural Catchment Scale: A Critical Review

“…While CSIA is today well-established for some legacy industrial compounds, pesticide CSIA is still emerging due to analytical challenges posed by low environmental concentrations (ng to µg L −1 ) and compound polarity. Overall, pesticide CSIA bears the potential to distinguish and quantify biotic and abiotic transformation of pesticides, such as the herbicide S-metolachlor, in ponds compartments [34], in soils [40], soil lysimeters [41,42] or even at the catchment scale [43]. Stable isotope data should be optimally interpreted with physicochemical and hydrological tracer data to evaluate retention and transport processes in ponds [44,45].…”
