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 waste glass was usually recycled in the generation of rock aggregate and concrete. However, the traditional utilization of waste glass hindered its potential application in resource recycling. This work produced the glass pumice via waste glass powder for the first time and evaluated its potential application as filled substrates in vertical subsurface flow constructed wetland. The performance of glass pumice in constructed wetland showed that the maximal removal of TSS, turbidity, COD, NH 4 + -N, TN and TP was 81.99 %, 88.62 %, 71.10 %, 83.64 %, 90.96 % and 58.88 %, respectively. The reduced hydraulic loading along with increased cycling times was in favor of the removal efficient of physical pollutants and nutrients, where the high specific surface area (>2 m 2 /g) of synthetic glass pumice enhanced capability of adsorption. In addition, the satisfying nutrient removal efficient attributed to glass pumice-mediated increased dissolved oxygen transfer rate in the vertical direction. The slow dissolution of exchangeable cations in glass pumice limited the adsorption and precipitation of phosphorus while the TP removal could only range from 16.30 %–58.88 %. The operating efficiency could be increased due to the occurrence of initial clogging while microorganisms subsequently attached to the glass pumice gradually formed biofilms to remove organic matters. The principal component analysis suggested environmental parameters were closely correlated to the operation performance of constructed wetlands. This study evaluated the performance of constructed wetland based on glass pumice and provided novelty insights into the resource recycling of waste glass.
