Per- and polyfluoroalkyl substances (PFAS) have been at the center of numerous toxicological and environmental concerns and regulatory scan- dals for two decades. Previous research has shown a long history of active obfuscation, misdirection (‘science bending’) and regulatory manipulation by the largest halogenation businesses, related to the depletion of the ozone layer and the toxicity of some fluorinated surfactants (PFOS and PFOA). We screened publications for potential evidence of other strategies of deception and obfuscated information regarding PFAS and fluoropolymers. A directed effort was identified to influence the scientific understanding of the environmental source and effects of ultrashort PFAS, especially trifluoroacetic acid (TFA). Critical issues in the current analytical approach to PFAS monitoring were identified, as well as evidence of a silently abandoned “total organofluoride” technique. The non-specific character of the production, incineration and degradation processes is discussed, inc

Our study presents a global assessment of microplastic pollution’s impact on food security. By analyzing a comprehensive dataset of 3,286 records, we quantify the reduction in photosynthesis caused by microplastics across various ecosystems.

De gevolgen van de opwarmende aarde worden steeds tastbaarder en treffen steeds grotere groepen mensen. In toenemende mate worden bedrijven en overheden aangeklaagd voor hun rol in de klimaatverandering. Jozef Seghers, student aan de Universiteit Gent, schreef er een thesis over.

IPCC Press Conference - Climate Change 2023: Synthesis Report

The IPCC is currently in its Sixth Assessment cycle, during which the IPCC will produce the Assessment reports of its three Working Groups, three Special Reports, a refinement to the methodology report and the Synthesis Report. The Synthesis Report will be the last of the AR6 products, due for release in March 2023.

This report synthesizes information from the 166 latest available nationally determined contributions communicated by 193 Parties to the Paris Agreement and recorded in the registry of nationally determined contributions as at 23 September 2022.
