Overall, gray treefrogs were relatively tolerant of chronic F3 alternative exposure. Across both experimental venues, there was limited evidence that metamorphic endpoints (e.g., time to metamorphosis, size at metamorphosis, survival to metamorphosis) were negatively affected by F3 alternatives compared ...
Conclusions: This cross-sectional study is the first to examine the relationship between PFAS exposure and CRH levels in mid-gestation. We found these associations were stronger among women who experienced stress, which aligns with previous findings that chemical and non-chemical stressor exposures can...
Here, we review present understanding of sources and trends in human exposure to poly- and perfluoroalkyl substances (PFASs) and epidemiologic evidence for impacts on cancer, immune function, metabolic outcomes, and neurodevelopment. More than 4000 PFASs have been manufactured by humans and hundreds ...
Table 1. Percent Composition and nominal concentrations (ng/L) of PFAAs in a 21-day, Aqueous exposure of Rainbow Trout. The relative compositions of PFAAs within the mixture groups (MIXLOW, MIXMED and MIXHI) are based on the composition of PFAAs detected in Lake Ontario (De Silva et al....

These results suggest that acute whole-body exposure to UWB pulses does not have a detrimental effect on the cardiovascular system.关键词: Experimental/ biological effects of microwaves electrocardiography haemodynamics/ Sprague-Dawley rats Bournlea ultra-wideband pulse generator ultra-wideband electromagnetic...
Firefighters are occupationally exposed to per- and polyfluoroalkyl substances (PFAS) in Aqueous Film Forming Foam (AFFF), a fire suppressant and in the moisture barrier of their safety gear. Certain PFAS are increasingly linked to metabolic toxicity and carcinogenicity. We examine changes in ...
•Tridol-S AFFF was found to be cyto- and genotoxic toAllium cepa.•Both the products decreased Mitotic index (MI) and increased chromosomal aberrations.•Tail DNA per cent and Olive tail moment increased with exposure concentration.•Tridol-S 3% was comparatively more toxic than Tridol-...
This study showcases the capability of a zebrafish-based platform to discern the developmental and behavioral toxicities associated with exposure to one AFFF and two F3 formulations. To facilitate direct exposure to the chemicals, embryos were enzymatically dechorionated and then exposed to the diluted...
In terms of the effects of RF field on brain function, Wang found that although single exposure to 1800 MHz RF field for 30 min with specific absorption rates (SARs) in brain at 2.42, 2.86 and 3.3 W/kg did not affect spontaneous locomotor activity, it increased recognition memory in mice...
