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).

Dioxin Cancer Risk — Example of Hormesis?
Dose-Response, 2005 A recent case-control study implied an inverse correlation between the measured body burden of dioxins (polychlorinated dibenzo- p -dioxins and polychlorinated dibenzofurans, PCDD/F) and the risk of soft tissue sarcoma in normal population exposed to ...

Environmental Toxicology, EarlyView.ABSTRACT Freshwater turtles are valuable sentinels of aquatic systems due to their long lifespans and resilience in environments impacted by contaminants. The Permian Basin, dominated by the oil and gas sector, spans western Texas and southeastern New Mexico, USA, including the Pecos River and its tributaries, the Delaware and Black Rivers.

Occupational exposure to polychlorinated biphenyls (PCBs). [PDF]
Environmental Health Perspectives, 1985 Human occupational exposure to polychlorinated biphenyls (PCBs) with varying chlorine content has been reported by several investigators, using analyses of blood or adipose samples or skin wipes to evaluate levels in the body. The intensity of occupational exposure is related to both duration and intensity of exposure.

Impact of Environmental Exposure on Infant Sleep : The Exposome Approach
Journal 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.

Exposure to Polychlorinated Biphenyls (PCBs) and Male Reproduction [PDF]
Systems Biology in Reproductive Medicine, 2010 Polychlorinated biphenyls (PCBs) are a class of persistent organic pollutants that were widely used in the mid-20th century. Though their production and use was banned by most countries several decades ago, the general population continues to be exposed due to the persistence and bioaccumulation of PCBs.

Implications of Maternal Toxicant Effects on Size‐Dependent Fisheries' Management: A Meta‐Analysis
Fish and Fisheries, Volume 27, Issue 4, Page 895-911, July 2026.Larger, older fish transfer higher mercury and PCB concentrations to their eggs, significantly reducing offspring hatching success, survival and growth rates in contaminated aquatic ecosystems. These findings suggest that the reproductive benefits of big old fat fecund female fish may be compromised by maternal toxicant transfer in polluted waters ...
