Dietary and nondietary accumulation of waterborne zinc (Zn) by shell of abalone Haliotis diversicolor supertexta was studied to determine if abalone shell can accumulate and eliminate Zn biokinetically. Shell of H. diversicolor supertexta rapidly accumulated Zn at microgram per gram concentrations during a 7-d uptake period for dietary and nondietary exposure to 1 microgml(-1) Zn seawater. Depu...

BACKGROUND Bisphenol A (BPA) is a widely produced endocrine-disrupting chemical. Diet is a primary route of exposure, but internal exposure (serum concentrations) in animals and humans has been measured only after single oral bolus administration. OBJECTIVE We compared serum concentrations of BPA over a 24-hr period after oral bolus administration or ad libitum feeding in mice and assessed fo...

8. Selected no-observed-effect levels (NOELs) and lowest-observed-effect levels (LOELs) of chlorothalonil from oral subchronic toxicity studies .. This risk assessment assessed the dietary exposure to chlorothalonil (2,4,5,6-tetrachloro-1,3-benzenedicarbonitrile), SDS-3701, and hexachlorobenzene (HCB) under the mandate of AB 2161 (known as the Food Safety Act) of California.

The aim of this study is to estimate dietary intake of benzoic acid and its salts through food additives in adult population of South East Serbia. Information on dietary intake among 620 adults (aged 18-65) was collected using a food frequency questionnaire, and 748 food samples were analyzed. The mean estimated intake of benzoic acid -0.32 mg/kg of body weight (bw) per day was below acceptable...

NHANES subjects self-identified as "Asian, Pacific Islander, Native American, or multiracial" (A/P/N/M) have higher levels of blood organic mercury than other racial/ethnic groups; however, the reasons for this have been unclear. This research uses exposure modeling to determine the reasons for elevated blood methylmercury (MeHg) levels, and also extends previous analyses of observed NHANES blo...

Although research suggests that fat talk, the normalized conversations that involve degrading one's body shape/weight and size, can increase body dissatisfaction and disordered eating behavior, the extent to which dietary restraint may moderate these relationships remains uncertain. A pilot study (N=30) comparing online videos with researcher-developed vignettes as prospective manipulations for...
