Impact of Environmental Exposure on Infant Sleep : The Exposome Approach

open access: yesJournal of Sleep Research, EarlyView.
This review explores how exposure to environmental pollutants during the first 1000 days of life may affect infant sleep. Evidence suggests potential links between chemical exposures and sleep disturbances, underscoring the need for more research on early‐life vulnerability and the impact of pollutants in air, diet, and breast milk.

Atmospheric Deposition of Organic Pollutants: A Comprehensive Review of Sampling and Analytical Methodologies

open access: yesAnalytical Science Advances, Volume 7, Issue 1, June 2026.
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 ...

Concentrations of Polychlorinated Biphenyls (PCBs), Polychlorinated Dibenzo-p-dioxins and Furans (PCDD/Fs), and Polybrominated Diphenyl Ethers (PBDEs) as Functions of Sample Depth in Killer Whale (Orcinus orca) Blubber [PDF]

open access: yes, 2007
Concentrations of polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), and polybrominated diphenyl ethers (PBDEs) were examined as a function of depth in killer whale (Orcinus orca) blubber samples.

Placental transfer of a hydroxylated polychlorinated biphenyl and effects on fetal and maternal thyroid hormone homeostasis in the rat [PDF]

open access: yes, 2002
Earlier studies at our laboratory indicated that several hydroxylated polychlorinated biphenyls (OH-PCBs) detected in human blood could specifically inhibit thyroxine (T4) transport by competitive binding to the thyroid hormone transport protein ...

Can starling eggs be useful as a biomonitoring tool to study organohalogenated contaminants on a worldwide scale?

open access: yesEnvironment International, 2013
Large-scale international monitoring studies are important to assess emission patterns and environmental distributions of organohalogenated contaminants (OHCs) on a worldwide scale. In this study, the presence of OHCs was investigated on three continents

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

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 4, April 2026.
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.

A Folding Magnetic Soft Sheet Robot With Real‐Time Reconfigurable Magnetization for Targeted Drug Delivery

open access: yesSmartBot, Volume 2, Issue 1, March 2026.
Magnetic robots have the characteristics of small size, non‐cable drive and motion agility, but multi‐angle folding and real‐time reconfigurable magnetization are difficult to be integrated into small‐sized soft structures. Here, the authors propose a magnetic soft sheet robot based on the dynamic magnetization characteristics of magnetorheological ...
