Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The purpose of the present study was to evaluate the presence of five neonicotinoid pesticides, acetamiprid, imidacloprid, clothianidin, thiacloprid, and thiamethoxam, in sheep and cow milk samples collected from animals bred in the Jordan Valley. In this area, numerous citrus plantations are present, and these insecticides are commonly used to protect plants from pests and diseases. Thirty-seven sheep milk samples and 31 cow milk samples were analysed. The analytical method, based on a single cleanup extraction step with SPE cartridges packed with diatomaceous earth material, together with analysis by LC–MS/MS, has guaranteed average recoveries between 75.1% and 88.3%, limits of detection (LOD) and quantification (LOQ) of 0.5 and 1 µg/kg, respectively, for all the five neonicotinoids. LOQ was much lower than the codex maximum residues limits for these pesticides in milks. No residues of the five neonicotinoids were found in any sample at a concentration level above LOD.
