Abstract: Human biomonitoring provides a scientific approach that systematically reveals exposure to phthalates through all possible routes. In this pilot study, fingernail was chosen as a non-destructive biospecimen to assess human exposure to nine phthalates. Concentrations of total phthalates ranged from 17.8 to 176娓璯/g (median: 65.4娓璯/g). Di(2-ethylhexyl) phthalate, di-Bu phthalate (DBP), and di-iso-Bu phthalate were the major compounds found in fingernails, accounting for 64.3%, 19.4%, and 12.9% of the total phthalates, resp. No significant difference in phthalates concentrations was found among genders and age-related distribution (p > 0.05). The concentration of DBP was pos. correlated with participants body mass index (r = 0.83). Our results suggested that fingernail can be used as a non-invasive biospecimen for the biomonitoring of human exposure to phthalates. Further studies are needed to investigate the relationship between phthalates or their metabolites in fingernail and other biol. samples, such as urine and blood. In the experiment, the researchers used many compounds, for example, Dicyclohexyl phthalate (cas: 84-61-7Recommanded Product: 84-61-7).
Dicyclohexyl phthalate (cas: 84-61-7) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is 绾?valerolactone.Recommanded Product: 84-61-7
