Determination of Pentachlorophenol in Seafood Samples from Zhejiang Province Using Pass-Through SPE-UPLC-MS/MS: Occurrence and Human Dietary Exposure Risk [PDF]

Molecules, 2023
Pentachlorophenol (PCP) has attracted wide attention due to its high toxicity, persistence, and bioaccumulation. In this study, a sensitive UPLC-MS/MS method for the determination of PCP in seafood samples was developed and validated.

Microbial Diversity of the Surface of Polypropylene and Low Density Polyethylene-Based Materials (Plastisphere) From an Area Subjected to Intensive Agriculture. [PDF]

Microbiologyopen
Bacterial communities colonizing LDPE and PP plastispheres from an intensive agriculture landfill exhibited differences in their taxonomic composition and structure. A predictive metagenomic analysis suggested physical and biological degradation of LDPE, in addition to degradation of plastic additives and herbicides by microorganisms present in both ...

Automated Analysis of Pollutants in Wastewater Using Atmospheric Pressure Gas Chromatography-Tandem Quadrupole Mass Spectrometer With Robotic Autosampler and Solid Phase Micro Extraction. [PDF]

J Sep Sci
ABSTRACT The analysis of organic pollutants using gas chromatography coupled to mass spectrometer (GC‐MS) with electron impact (EI) ionization and liquid–liquid or solid‐phase extraction (LLE or SPE) often suffer from a limited selectivity and arduous sample preparation.

Biowaste-source-dependent synthetic pathways of redox functional groups within humic acids favoring pentachlorophenol dechlorination in composting process

Environment International, 2020
Humic acids (HAs) can function as electron mediators for contaminants transformation in different environments. The humus respiration can facilitate pentachlorophenol (PCP) dechlorination during different biowastes composting.

The impact on the soil microbial community and enzyme activity of two earthworm species during the bioremediation of pentachlorophenol-contaminated soils [PDF]

Journal of Hazardous Materials, 2016
The ecological effect of earthworms on the fate of soil pentachlorophenol (PCP) differs with species. This study addressed the roles and mechanisms by which two earthworm species (epigeic Eisenia fetida and endogeic Amynthas robustus E.
