Review of online measurement techniques for chemical composition of atmospheric clusters and sub-20 nm particles

Frontiers in Environmental Science, 2022
The chemical composition of aerosol particles is crucial to understanding their formation and evolution in the atmosphere. However, very limited information is available for the chemical composition of ultrafine particles, particularly for nanoclusters ...

Dataset of pollutants in organic and non-organic food

Data in Brief, 2022
Organic and non-organic equivalent corresponding type of foods were assessed for pollutants, polycyclic aromatic hydrocarbons (PAHs), pesticides and heavy metals. In total, 35 samples of sausages and cheeses were tested from three western European countries, Spain, France, and Germany.

Effects of Pollution on Marine Organisms [PDF]

Water Environment Research, 2015
This review covers selected 2017 articles on the biological effects of pollutants and human physical disturbances on marine and estuarine plants, animals, ecosystems and habitats. The review, based largely on journal articles, covers field and laboratory measurement activities (bioaccumulation of contaminants, field assessment surveys, toxicity testing

Characteristics and degradation of organic aerosols from cooking sources based on hourly observations of organic molecular markers in urban environments [PDF]

Atmospheric Chemistry and Physics, 2023
Molecular markers in organic aerosol (OA) provide specific source information on PM2.5, and the contribution of cooking organic aerosols to OA is significant, especially in urban environments.

Digital PCR as an Emerging Tool for Monitoring of Microbial Biodegradation

Molecules, 2020
Biodegradation of contaminants is extremely complicated due to unpredictable microbial behaviors. Monitoring of microbial biodegradation drives us to determine (1) the amounts of specific degrading microbes, (2) the abundance, and (3) expression level of

Measurement report: Size-resolved particle effective density measured by an AAC-SMPS and implications for chemical composition [PDF]

Atmospheric Chemistry and Physics
The effective density (ρeff) is closely associated with the aging process and can serve as a tracer of chemical composition. Recently, studies investigating the effect of particle size on density have been limited.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron
