Neurobehavioral hazard identification and characterization for caffeine

open access: yesRegulatory Toxicology and Pharmacology, 2016
This report evaluates the scientific literature on caffeine with respect to potential central nervous system (CNS) effects, specifically effects on sleep, anxiety, and aggression/risk-taking. Caffeine has been the subject of more scientific safety studies than any other food ingredient. It is important, therefore, to evaluate new studies in the context

Characterization of the toxicological hazards of hydrocarbon solvents [PDF]

open access: yesCritical Reviews in Toxicology, 2015
Hydrocarbon solvents are liquid hydrocarbon fractions derived from petroleum processing streams, containing only carbon and hydrogen atoms, with carbon numbers ranging from approximately C5-C20 and boiling between approximately 35-370°C. Many of the hydrocarbon solvents have complex and variable compositions with constituents of 4 types, alkanes ...
