The issue 47 of OFFICINA* amis to define the theme of toxic legacies refer to all these inconvenient tangible and intangible inheritances, collective objects of questioning, conflict, debate, and sometimes denial. These legacies extend beyond the physical boundaries and imaginary narratives of a specific site or case study, shedding light on how di...

Honey bees are commonly exposed to a broad spectrum of xenobiotics, including heavy metals. Heavy metal toxicity is of concern in the context of global pollinator declines, especially since honey bees seem to be particularly susceptible to xenobiotics in general. Here we summarize current knowledge on the interplay between cadmium, one of the most ...
The presentation explores the local contamination caused by spheroidal carbonaceous particles (SCPs) in the Haut Vicdessos region, Pyrenees. SCPs, known markers of industrial pollution, were studied using environmental archives like peat bogs, which record atmospheric deposition over time.Peat bogs, particularly Sphagnum species, serve as valuable ...
The PVC plastic project investigates microplastic deposition in the upper Vicdessos region. Initial studies used peat and lake archives to identify microplastics in the Arbu catchment, alongside findings of large microplastics in trout, sediments, and biofilms in other Pyrenees valley. We sought to establish a 10-year atmospheric chronology of micr...
Background: The Water Distribution Administration of the Democratic Republic of Congo (REGIDESO) faces many challenges, particularly related to unregulated human activities on all watercourses used for the treatment of water intended for human consumption in general and in particular around the watershed of the N'djili River, a river that feeds the...

This study analysed ten widely used commercial fishfeeds in aquaculture from six countries spanning three continents to assess microplastic (MP) contamination. MPs with an average abundance of 1130 ± 259.07 particles/kg and an average length of 2.64 ± 0.62 mm ( ± SE) were found in aquaculture feeds, with fibres (85 %) and fragments (15 %). The majo...
Soil pollution in the European Union (EU) is poorly quantified, because of several years of reduced attention and limited funding on soil research and monitoring. Moreover, issues such as different monitoring methodologies within Member States (MS), and quantification methods focused on pseudototal rather than the available fraction of pollutants, ...

Pressure drop in spacecraft internal cavities at their arrival on orbit is not as quick as it could be inferred from ambient pressure drop. This induces risks of corona discharges or (re)condensation, in particular when turning on or heating up sub-systems. At the origin of this phenomenon, the outgassing of internal cavities submitted to vacuum, a...
Important degradations of white silicone paints were observed in low Earth orbit (LEO) on CNES' THERME experiments. These degradations were in the order of 0.2 to 0.3 in terms of solar absorptance (αS) increase in as little as a few years whereas other materials such as Kapton films or Teflon secondary surface mirrors (SSM) did not age nearly as mu...
