2-pentanone production from hexanoic acid by Penicillium roqueforti from blue cheese:is this the pathway used in humans? [PDF]
Production of 2-pentanone, a methylketone, is increased in fasting ketotic humans. Its origin is unknown. We hypothesised that it is formed via β-oxidation of hexanoic acid by the peroxisomal pathway proposed for methylketone-producing fungi and yeasts ...

Electrospun Fibers for Solid-Phase Microextraction
A method of producing solid-phase microextraction (SPME) fibers based on electrospinning polymers into nanofibrous mats is demonstrated. Using this method the polymer mat is attached to a stainless steel wire without the need of a binder. While applicable to any polymer that can be electrospun, a polymeric negative photoresist, SU-8 2100, is used for ...

ABSTRACT Atmospheric deposition of organic pollutants plays a crucial role in the transport and fate of contaminants in the environment, with implications for ecosystem health and human exposure. Persistent organic pollutants (POPs), polycyclic aromatic hydrocarbons (PAHs) and microplastics are increasingly recognized as transboundary threats due to ...

Determination of pesticides in the respirable fraction of airborne particulate matter by high-performance liquid chromatography–tandem mass spectrometry [PDF]
Potential harmful effects of pesticides include risks to human health of workers involved in the wet spray application in cultivated areas. Inhalation exposure depends on several factors including pesticide concentrations in the respirable fraction of ...

Use of a new enrichment nanosorbent for speciation of mercury by FI-CV-ICP-MS [PDF]
Mercury is one of the most toxic environmental pollutants and its effects on human and ecosystem health are well known. All mercury species are toxic, with organic mercury compounds generally being more toxic than inorganic species.
