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 current study was designed to evaluate genotoxicity of different sizes of iron oxide nanoparticles (IONPs) and ionic iron using coelomocytes of the earthworms Eisenia hortensis. Earthworms were exposed to different series of IONPs and ionic iron concentrations to find the respective LC50 of the chosen chemicals. LC for < 50, <100 nm and the ionic iron of IONPs were 500, 200, 250 µg/mL respectively. Concentrations of LC/2 (250, 100, 125 µg/mL for < 50, <100 nm and the ionic iron respectively) and LC for 48 h were used to perform the comet assay and micronucleus test. Statistically significant (p < 0.05) increase in DNA and chromosomal damage was observed for all sizes of IONPs and ionic iron. In the comet assay system, the greatest genotoxicity was observed in the treatments with < 100 nm IONPs, whereas the greatest numbers of micronuclei and binucleate cells were observed in the treatments with ionic iron. It was concluded that different types of nanoparticles (i.e. sizes, shapes) may have different genotoxic potencies in different assays with E. hortensis earthworms.
