Methane is a potent greenhouse gas and as an air pollutant it contributes to tropospheric ozone formation, which is detrimental to health. About 60% of total global methane emissions stems from anthropogenic emissions, and about 40% from natural sources. In 2022, Europe contributed to 5.2% of...

Air pollution, especially ground-level ozone, poses severe threats to human health and ecosystems. Accurate forecasting of ozone concentrations is essential for reducing its adverse effects. This study aims to use the functional time series approach to model ozone concentrations, a method less...

Catalytic ozonation is an effective technology widely used in advanced treatment to remove refractory organics from wastewater. Meanwhile, it is also a highly energy-consuming technology, usually accounting for 30%~40% of the total electricity consumption of a wastewater treatment plant (WWTP)....

This study successfully developed a nanocomposite catalyst (Co2SnO4@rGO) at optimal composite ratio of 2:1 between Co2SnO4 and GO for effectively activation of peroxymonosulfate (PMS) to degrade cefalexin (CFX) from aqueous solution by hybrid ozonation system (O3/Co2SnO4@rGO/PMS). The CFX...

This paper revisits one of the rare success stories in global environmental cooperation: the Montreal Protocol and the phase-out of ozone-depleting substances. I show that the protocol increased science and innovation on alternatives to ozone-depleting substances, and argue that agreements can...

The Coordinated Activities on the Safety of Products (CASP) projects enable all the market surveillance authorities (MSAs) from European Union (EU) / European Economic Area (EEA) countries to jointly ensure that unsafe products are swiftly removed from the Single Market. This activity focused on...
