“…The residues percentages of tested pesticides detected during 60 days after application are shown in Table (3 soil (10.53, 8.94, 53.09, and 13.84% of the initial residue remaining), respectively. As with the other studies, the residues of pesticides into soils declined with time (Akoijam and Singh, 2014;Badawy et al, 2017). However, DNF and IMI dissipated slowly compared with BTZ and BPS into three soils, as shown in Fig.…”

“…Accordingly, the first-order equation is most suitable to describe the persistence kinetics of BTZ, BPS, DNF and IMI into alluvial soil, calcareous soil and sandy soil. It was reported that first-order kinetic equation is commonly used in describing the persistence kinetics of various pesticides in soil (Badawy et al, 2017), it was the best model for the persistence kinetics of BTZ (Ke-Bin et al, 2008;Paszko and Muszyński, 2017;Schuhmann et al, 2019), BPS (Zhang et al, 2013), DNF (Kobashi et al, 2017;Li et al, 2022) and IMI (Akoijam and Singh, 2014;Kobashi et al, 2017;Li et al, 2022;Sharma and Singh, 2014).…”

The degradation and persistence of two herbicides (bentazone BTZ & bispyribac-sodium BPS), and two insecticides (dinotefuran DNF & imidacloprid IMI) into alluvial soil, calcareous soil and sandy soil were investigated following application at 100 µg/g soil at various time intervals; 0, 3, 7, 15, 30 and 60 days by HPLC. BTZ, BPS, DNF and IMI residue dropped after 60 days of incubation to 7.13, 4.85, 53.71, and 7.51% into alluvial soil, 8.58, 5.28, 17.68, and 12.56 % into calcareous soil, and 10.53, 8.94, 53.09, and 13.84% into sandy soil of the initial residue remaining, respectively. DNF, and IMI dissipated slowly compared with BTZ and BPS into three soils. The dissipation of tested pesticides was faster in alluvial soil, followed by calcareous soil and then sandy soil, except of DNF. The persistence kinetics of BTZ, BPS, DNF and IMI into alluvial, calcareous and sandy soil was analyzed using different orders kinetics. The different orders kinetics results showed that first-order model fit the experimental persistence data quite well of BTZ, BPS, DNF and IMI into tested soils with high values of R2 and low values of Δqe% and SSE. The half-life values were 15.27, 16.39 and 17.82 days of BTZ, 11.73, 13.10 and 16.20 days of BPS, 63.01, 23.42 and 75.34 days of DNF, and 14.87, 20.39 and 14.87 days of IMI into alluvial soil, calcareous soil and sandy soil, respectively.

Abstract. El-Aswad AF, Fouad MR, Aly MI. 2023. Assessment of the acute toxicity of agrochemicals on earthworm (Aporrectodea caliginosa) using filter paper contact and soil mixing tests. Asian J Agric 7: 14-19. Earthworms are suitable bioindicators of chemical contamination in terrestrial ecosystems. Therefore, adult earthworms (Aporrectodea caliginosa Savigny, 1826), which are common in Egyptian rice fields were used to study the side effects of fenitrothion and thiobencarb. Also, it was used two common Egyptian soil types; alluvial soil (clay soil) and the calcareous soil (sandy clay loam soil). Two tests were used; filter paper contact test at 24, 48 and 72 h, and the soil mixing test at 5 and 10 days. The effect of both pesticides on mortality of earthworm was insignificant at 24 h with a low mortality percentage. LC50 value of fenitrothion and thiobencarb were 83.16, 288.26, 24.67, and 39.98 µg a.i mL-1 at 48 and 72 h, respectively. Based on the LC50 values, fenitrothion was 3.5 and 1.6 times more toxic than thiobencarb at 48 and 72 h, respectively. At 5 and 10 days after treatment, respectively, the LC50 for fenitrothion in the soil mixing test decreased from 334.27 to 55.45 in clay soil and from (415.90) to (25.00) in sandy soil. Regarding to fenitrothion in soil mixing test, the LC50 was reduced from 334.27 to 55.45 in clay soil and from 415.90 to 25.00 in sandy soil at 5 and 10 days after treatment, respectively. Also, the LC50 of thiobencarb in clay soil was decreased from 0.93 to 0.41 and from 55.28 to 10.65 at 5 and 10 days, respectively. In general, a positive relation was recorded between the tested pesticide toxicity on earthworm and concentrations, and also exposure time. Fenitrothion was more toxic on earthworm in contact filter paper test than thiobencarb. While, in clay soil, fenitrothion was least toxic to the earthworm in soil mixing test, this could be attributed to the slow degradation in the worms and subsequently less elimination of the metabolites as well as attributed to its higher adsorption and lower desorption in soil.
