Toxicity of chemical mixtures
Potential chemical mixtures exposures of . A challenge in conducting mixtures assessment is the lack of useful hazard and dose response data and other information on chemical mixtures. T. When an individual inhales toxic chemical fumes, he or she is likely to experience difficulties in breathing, inflammation of lungs, pneumonia and swallowing problems, which can be life threatening. Examination of new case studies, as well as those previously reported, shows that when the human body is exposed to mixtures of chemicals that include lipophilic and hydrophilic species, the lipophiles facilitate the absorption of the hydrophiles at enhanced levels and produce effects that are not expected from an individual chemical. Examination of new case studies, as well as those previously reported, shows that when the human body is exposed to mixtures of chemicals that include lipophilic and hydrophilic species, the lipophiles facilitate the absorption of the hydrophiles at enhanced levels and produce effects that are not expected from an individual chemical. Exposures to chemical mixtures have reportedly produced unexpected effects. Chemical mixtures are ever varying with respect to constituents and to concentrations of those constituents. The authors' recommendation that toxicity of chemical mixtures be directly assessed on a case-by-case basis (Tinwell and Ashby ) would provide a Band-Aid but not a cure to the dilemma of characterizing the hazards of chemical mixtures. Most importantly, the nature of toxicity of these studied . Jan 31, · Although toxicity data are available for individual chemicals, generally there is no toxicity data of chemical mixtures. Most highlighters, pens and markers contain dyes, trace amounts of alcohol and a chemical known as glycol or glycol. Highlighters are minimally toxic and do not pose a serious treat to anyone’s health.
