Sponge city strategy and application of pavement materials in sponge city
Xin Guan,Jiayu Wang,Feipeng Xiao +2 more
TL;DR: Wang et al. as mentioned in this paper reviewed the application and development of pavement materials in sponge city and found that the permeable pavements were not necessarily more environmentally friendly than traditional pavement, but they did have some obvious benefits such as water purification, traffic noise reduction, Urban Heat Island mitigation, and waste materials recycling.

A review of potentially low-cost sorbents for heavy metals
TL;DR: The use of low-cost sorbents has been investigated as a replacement for current costly methods of removing heavy metals from solution as mentioned in this paper, where natural materials or waste products from certain industries with a high capacity for heavy metals can be obtained, employed and disposed of with little cost.

Eutrophication: impacts of excess nutrient inputs on freshwater, marine, and terrestrial ecosystems
TL;DR: Two brief case studies demonstrate that nutrient loading restriction is the essential cornerstone of aquatic eutrophication control, and results of a preliminary statistical analysis are presented consistent with the hypothesis that anthropogenic emissions of oxidized nitrogen could be influencing atmospheric levels of carbon dioxide via nitrogen stimulation of global primary production.
