“…Fifteen composite soil samples at 0–20 cm depth were taken from randomly selected tomato and onion seedling beds/plots from three sampling sites using a stainless steel auger. This was done in August 2022 (during the rainy season), following the procedure reported by Mondal [ 16 ]. Each soil sample weighed about 1 kg, obtained by collecting six subsamples in a zig-zag pattern and pooled together to form a composite sample.…”

Research on heavy metal pollution in horticultural farms located around lakes in the Central Ethiopian Rift Valley Region has focused on measuring the levels of heavy metals and their health implications. However, the ecological risks of horticultural farms contaminated with heavy metals in this region have not been studied. The current study addresses this gap by providing information on the degree of heavy metal contamination and the ecological risk associated with horticultural farms around Lake Ziway, using various pollution indices. An inductively coupled plasma optical emission spectrometer (ICP-OES) was used to measure the concentrations of nine heavy metals (As, Cd, Co, Cu, Cr, Ni, Pb, Hg, and Zn) in a total of 30 composite soil and irrigation water samples, each consisting of a mix of six subsamples. The results indicated that the mean concentrations of Hg, Cd, Pb, and Zn in soils collected from all the sampling sites exceeded the FAO/WHO maximum permissible limit (MPL). The values of both the contamination factor (CF) and contamination degree (Cd) of the heavy metals ranged from 0.04 to 2.66 and 2.81 to 6.14, respectively, indicating a low to medium level of contamination for both indices. The pollution load index (PLI) values of 0.451, 0.449, and 0.157 for sites 2, 1, and 3, respectively, indicate “unpolluted” to “moderately polluted” levels of heavy metal pollution. However, the ecological risk indices (ERIs) at sites 2 and 1 (158.92 and 141, respectively) showed a potentially high ecological risk due to soil pollution. Therefore, close monitoring and early intervention mechanisms must be in place to control pollution in the study area.

“…In modern agricultural practices, the application of pesticides has been unavoidable to increase crop productivity and quality. Pesticides are not only detrimental to human and animal health but also to the environment (EC 2007; Mondal et al 2020;Asensio-Ramos et al 2010). And, the widespread and indiscriminate use of pesticides has become a global concern with regard to food safety.…”

“…Soil is a heterogeneous complex matrix consisting of organic (humas 10-15%, lipids, carbohydrates, lignin, avonoids, pigments, resins and fulvic acids) and inorganic (variable percentage of sand, silt, and clay) components (Łozowicka et al 2017). Because of the polar, non-polar and ionic activities of pesticides, they are often retained in the soil (Mondal et al 2020), making residue analysis di cult. Besides, a pesticide is likely to be exposed to chemical as well as microbial degradation, producing metabolites of variable toxicological signi cance.…”

The paper aimed to develop an effective multiresidue extraction method in three major soil types, namely i) new alluvial soil (NAS); ii) red lateritic soil (RS) and iii) black soil (BS) in the Indian subcontinent for determining the residues of pesticides from various chemical classes. To establish an effective pre-treatment process, an ethyl acetate-based extraction method with a freezing out cleanup step was employed. The analysis was performed using gas chromatographytandem mass spectrometry (GC-MS/MS). The validation experiments were performed on 220 GC-amenable pesticides by spiking all soil samples. The linearity of the calibration curves was satisfactory in matrix-matched standards and yielded the coe cients of determination (R 2 ) ≥0.99 for approximately 98% of the target analytes in all matrices. At 10 ng/g, the recoveries of the spiked pesticides were in the range of 70-120%, with associated precision-RSD values ≤20% for approximately 85%, 88.6% and 89% of the compounds for BS, RS and NAS respectively. At the higher spiking levels of 20 and 50 ng/g, average recoveries and RSDs readily met the validation criteria of all the studied pesticides. Overall, the method holds potential as a suitable procedure for multiresidue analysis in soils for safety evaluation and risk assessment purposes. HighlightsA multiresidue method is reported for simultaneous analysis of multiclass pesticides in soilThe soil types represented the major crop growing areas of the Indian subcontinent Sample preparation involved extraction with ethyl acetate and cleanup by a freezing stepThe residues were estimated by gas chromatography tandem mass spectrometryThe method sensitivity, accuracy and precision complied with the SANTE/12682/2019 guidelines
