In order to ensure the excellent performance of a nonthermal plasma (NTP)-catalysis system, a highly efficient catalyst is generally required. In this study, nitrogen-enriched hollow hybrid carbon (N-C) catalysts were designed, synthesized through facile pyrolysis of a zeolitic imidazolate framework precursor, and used as a support on which to disp...
Landfill leachate contains ammonium and micropollutants. Ammonium can be biologically removed but biorecalcitrant micropollutants removal requires post-treatment like ozonation. This study developed an expanded clay aggregates packed biofilm column (EBC) and demonstrated its feasibility of coupling biodegradation and ozonation (CBAO) to simultaneou...
The non-thermal plasma (NTP) treatment of food products as an alternative for thermal processing has been investigated over the last few years. This quasi-neutral gas contains a wide variety of reactive oxygen and nitrogen species (RONS), which could be lethal for bacterial cells present in the product. However, apart from only targeting bacteria, ...

Estimating the impact of climate change and emission scenarios on air pollution can be done using regional climate models (RCMs). Climate uncertainties are commonly estimated using RCM ensembles such as provided by EURO-CORDEX. Despite the strong relations between the weather and air pollutants, interactions are usually complex and require meteorol...
Volatile organic compounds (VOCs) have become a major human wellbeing and environmental concern worldwide. However, evidence on VOC concentrations in primary school environments in Africa, including Ethiopia, is scarce. The goal of this research was to examine VOCs in primary schools in Hawassa, Ethiopia, and to evaluate possible health threats. Co...
Phosphonate contamination of water resources has drawn much attention. Advanced oxidation combined with phosphorus recovery is considered as a promising solution, but the development of a cost-efficient process remains challenging. This work demonstrates an effective two-step process including a plasma-based oxidation of phosphonate, followed by ph...
Within Flanders, there is an increasing trend to let children sleep outdoors while in daycare. However, within an urban environment, the densely spread emission sources might affect the air quality and possibly limit the areas where outdoor sleeping is favourable. Nevertheless, there is a lack of data regarding the atmospheric pollution levels in a...
Nonthermal plasma is a mild processing technology for food preservation. Its impact on lipid oxidation was investigated in this study. Stripped methylesters were considered as a basic lipid model system and were treated by a multihollow surface dielectric barrier discharge. In dry air plasma, O-3, .NO2, .NO3, and O-1(2) were identified as the main ...
BACKGROUND: The aetiology of chronic rhinosinusitis (CRS) is multifactorial with a complex interplay between environmental, microbial endogenous and genetic factors. The impact of outdoor air pollution on prevalence or severity of CRS remains largely unknown. METHODS: Real-life geolocation data (2017-2018, Belgium) from 278 CRS patients (2576 healt...
