This paper describes a new method (DREAM) for structured, semi-quantitative dermal exposure assessment for chemical or biological agents that can be used in occupational hygiene or epidemiology. It is anticipated that DREAM could serve as an initial assessment of dermal exposure, amongst others, resulting in a ranking of tasks and subsequently jobs. DREAM consists of an inventory and evaluation part. Two examples of dermal exposure of workers of a car-construction company show that DREAM characterizes tasks and gives insight into exposure mechanisms, forming a basis for systematic exposure reduction. DREAM supplies estimates for exposure levels on the outside clothing layer as well as on skin, and provides insight into the distribution of dermal exposure over the body. Together with the ranking of tasks and people, this provides information for measurement strategies and helps to determine who, where and what to measure. In addition to dermal exposure assessment, the systematic description of dermal exposure pathways helps to prioritize and determine most adequate measurement strategies and methods. DREAM could be a promising approach for structured, semi-quantitative, dermal exposure assessment.

Cutaneous photoaging, induced by chronic exposure to ultraviolet (UV) radiation, typically manifests as alterations in both the physical appearance and functional properties of the skin and may predispose individuals to cancer development. Recent studies have demonstrated the reparative potential of exosomes derived from mesenchymal stem cells in addressing skin damage, while specific reports highlight their efficacy in ameliorating skin photoaging. However, the precise role of exosomes derived from human hair follicle mesenchymal stem cells (HFMSC-Exos) in the context of cutaneous photoaging remains largely unexplored.

Lead (Pb) is an environmental toxin ubiquitously present in the human environment due to anthropogenic activities and industrialization. Lead can enter the human body through various sources and pathways, such as inhalation, ingestion and dermal contact, leading to detrimental health effects. The majority of lead that enters the body is removed by urine or feces; however, under chronic exposure conditions, lead is not efficient, as lead is absorbed and transferred to numerous organs, such as the brain, liver, kidney, muscles, and heart, and it is ultimately stored in mineralizing tissues such as bones and teeth.

The distribution and transport of polycyclic aromatic hydrocarbons (PAHs) in urban environments are influenced by both anthropogenic sources and natural landscape features. While previous research has primarily focused on human activities as drivers of PAH pollution, the role of terrain-especially in cities with complex topographies-remains underexplored. To investigate the effect of terrain features on PAH distribution and transport, we analyzed topsoil samples evenly distributed in Chongqing, a city with hilly terrain (elevation: 48-2300 m).
