Recent Developments in Sustainable Composites for Printed Circuit Boards (PCBs): A Review

Macromolecular Materials and Engineering, EarlyView.
This review presents the potential of using natural plant fibers and biodegradable polymers as sustainable printed circuit boards (PCBs). This review provides future directions in innovation and sustainable PCBs development. Bio‐composites PCBs are both environmentally friendly and sustainable due to the natural fibres they contain.

Environmental contamination of free-range hen with dioxin

Journal of Veterinary Research, 2021
The transfer of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and polychlorinated biphenyls (PCBs) from a contaminated environment into the food chain is a serious consumer safety problem.

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Quality of cultured eels as affected by pollution sources and risk assessment of dioxins and dioxin-like polychlorinated biphenyls

Food Production, Processing and Nutrition
The aim of this research was to determine the residues of dioxins and dioxin-like polychlorinated biphenyls in cultured eel and find out the source of pollution and the distribution pattern of eels.

Monitoring of polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans, and polychlorinated biphenyls in Estonian food; pp. 193–200 [PDF]

Proceedings of the Estonian Academy of Sciences, 2011
Persistent organic pollutants are mainly compounds that include chlorine, which are posing a threat to human health and impairing living organisms and ecosystems due to their toxicity, persistence, and bioaccumulation.

Metals' Adsorption Onto Environmental Microplastics at Shoreline Sediments

X-Ray Spectrometry, EarlyView.
ABSTRACT This study assessed trace element concentrations and microplastic (MP) contamination in three sandy beaches on the southern coast of Ilha Grande (Rio de Janeiro, Brazil). Environmental MPs were manually extracted from sand samples, and beaches were classified using the microplastic pollution index (MPPI).

Persistent organic pollutants and cognitive decline among middle-aged or older adults in the Hispanic Community Health Study/Study of Latinos

Ecotoxicology and Environmental Safety
Persistent organic pollutants may negatively impact cognition; however, associations between persistent organic pollutants and changes in cognition among United States Hispanic/Latino adults have not been investigated.

Investigation of Dielectric and Thermal Properties of Mineral Oil‐Based Fe3O4‐Coated SiO2 Core‐Shell Nanofluids

High Voltage, EarlyView.
ABSTRACT This study investigates the dielectric and thermal properties of transformer oil‐based nanofluids incorporating Fe3O4‐coated SiO2 core–shell nanoparticles as nanofillers. The nanoparticles were synthesised with varying shell thicknesses, and two samples underwent surface treatment.

Persistent organic pollutants in the Atlantic and southern oceans and oceanic atmosphere [PDF]

, 2017
Persistent organic pollutants (POPs) continue to cycle through the atmosphere and hydrosphere despite banned or severely restricted usages. Global scale analyses of POPs are challenging, but knowledge of the current distribution of these compounds is ...
