Abstract. It has recently been established that unsaturated water-soluble organic compounds (UWSOCs) might efficiently form oligomers in polluted fogs and wet aerosol particles, even for weakly soluble ones like methyl vinyl ketone (MVK). The atmospheric relevance of these processes is explored by means multiphase process model studies a companion paper. In the present study, we investigate aging aqueous-phase MVK formed via •OH oxidation, as well their ability to secondary (SOA) upon water...
Bromoform (CHBr3) belongs to very-short-lived substances (VSLSs), which are important precursors of reactive bromine species (BrOx) contributing tropospheric and stratospheric chemistry. To date, most models calculating product emissions the atmosphere only consider natural production CHBr3 from marine organisms such as macroalgae phytoplankton. However, has many other anthropogenic sources (coastal industrial sites, desalination wastewater plants, ballast waters, seawater toilets) that may...
Soil contamination pattern due to industrial activities often leads high concentrations of potentially toxic elements (PTE) decreasing with depth. This spatial heterogeneity the soil may have significant consequences on properties and living communities. We evaluated effects both surface solum Coronilla juncea L. (Fabaceae) functional traits in field conditions phytostabilization potential this species. Plant samples were collected 3 sites along a PTE gradient. The correlations between...
The aim of this study was to investigate the photoactivity dioxide titanium (TiO2) nanotube films depending on different structure factors including pore size, tube length, wall thickness and crystallinity. Aqueous p-nitroaniline used as a probe assess photocatalytic activity layers under UV irradiations. Self-organized thin were prepared by electrochemical anodization (Ti) foils Ti sputtered onto silicon (Si). amorphous as-formed then annealed at temperatures ranging from 450 900 °C in...
This work proposes a suitable treatment for the leachates from sewage sludge composting process using specific windrow (biopile). The biopile’s evolution and organic content degradation were followed 2 months with regular leachate spraying to assess physico-chemical biological impacts, determine risk of enrichment certain monitored pollutants. final objective was valorization biopile substrates in process, while respecting quality standards use circular economy way. Classical parameters (pH,...
The selection of plant species at mine sites is mostly based on metal content in parts. Recent works have proposed referring to certain ecological aspects. However, traits for metal-tolerance still need be accurately assessed the field. An abandoned Zn-Pb site Gard (France) offered opportunity test a set criteria. diversity micro-habitats was first recorded through floristic relevés and selected categorical measured were compared selection. composition study consisted 61 from 31 families....
Abstract. Secondary organic aerosol (SOA) represents a substantial part of aerosol, which affects climate and human health. It is now accepted that one the important pathways SOA formation occurs via aqueous phase chemistry in atmosphere. Recently, we have shown previous study (Renard et al., 2013) mechanism oligomerization MVK (methyl vinyl ketone), suggested unsaturated water soluble compounds (UWSOC) might efficiently form wet particles, even for weakly ones like MVK. The atmospheric...
