Re‐assessment of the risks to public health related to the genotoxicity of styrene present in plastic food contact materials

EFSA Journal, Volume 23, Issue 6, June 2025.
Abstract The EFSA Panel on Food Contact Materials (FCM) was requested by the European Commission to re‐evaluate the potential genotoxicity of styrene after oral exposure and its safety for use in plastic FCM with a specific migration limit (SML) of 40 μg/kg food.

Feasibility for Mapping Radon Exhalation Rate from Soil in China [PDF]

Journal of Nuclear Science and Technology, 2004
Radon exhalation rate from soil is one of the most important factors for evaluation of the environmental radon level. For rough estimation of the nationwide radon exhalation rate from soil in China, a simple model was derived under the review and analysis of several previous works on radon exhalation theories. To show the feasibility of the model, some

Functional Lung Imaging Identifies Peripheral Ventilation Changes in ꞵ‐ENaC Mice

Respirology, Volume 30, Issue 4, Page 335-345, April 2025.
β‐ENaC‐Tg mice have previously been shown to exhibit muco‐obstructive disease and emphysema. This study analysed lung function in β‐ENaC‐Tg mice using XV functional imaging and flexiVent assessments. XV enabled ventilation defects to be identified and localised, and the flexiVent comfirmed increased lung compliance and reduced tissue elastance ...

T1‐T2 Interplay in the Complex Immune Landscape of Severe Asthma

Immunological Reviews, Volume 330, Issue 1, March 2025.
ABSTRACT Asthma is orchestrated by an aberrant immune response involving a complex interplay between multiple inflammatory cell types. An increase in Th2 cells in the asthmatic airway is a hallmark of asthma, and biologics blocking their effector functions have been life‐changing for many severe asthma patients who poorly respond to immunosuppression ...

Radon and thoron exhalation rate measurements from building materials used in Serbia

Nukleonika, 2020
The second most important source of indoor radon, after soil beneath dwelling, is building material. With the increase in environmental awareness and new energy-saving policies, residents tend to replace the existing windows with tighter windows, which ...

Exhalation rate of radon-222 from concrete and cement mortar

Nukleonika, 2018
The main sources of radon in the air of dwellings are soil, building materials, and groundwater. This study aimed to determine the exhalation rate of 222Rn from samples made of concrete and cement mortars, as well as to evaluate by means of gamma ...
