The occurrence of deoxynivalenol (DON) in retail foods in Tehran (Iran) was determined using high-performance liquid chromatography technique and immunoaffinity column as the clean-up step. A method was validated for analysis of DON in rice, bread, puffed corn snack and wheat flour. The average recoveries and precision (RSD) for DON in different foods ranged 84.2-93.1% and 2.9-12.0%, respective...

CONTEXT Dental and skeletal fluorosis is endemic in the Ethiopian Rift Valley. Children are especially vulnerable to excessive fluoride intake because their permanent teeth are still being formed. Strategies to reduce the total fluoride intake by children are thus warranted. CASE PRESENTATION By combining the results of field studies in Ethiopia, the relevant pathways for fluoride intake have...

A sensitive, monoclonal antibody-based ELISA test was developed and used for quantitative determination of ochratoxin A (OA) in human sera. The measuring range of this test (without sample dilution) was 0.2-2.0 ng/mL, and the detection limit was 0.2 ng/mL. The OA concentrations of 355 sera samples varied from < 0.2 to 10 ng/mL OA, but 75% of the samples contained 0.2-1.0 ng/mL. This amount refl...

To estimate Cu exposure level from wine consumption and to assess possible health risk for moderate wine consumers, wine samples were collected from different wine-growing areas of Croatia. Median concentrations were 180 μg L-1, range (76 to 292) μg L-1, in commercial wines and 258 μg L-1, range (115 to 7600) μg L-1, in homemade wines (P>0.05). Maximum permitted level of 1000 μg L-1 was exceede...

Bisphenol A (BPA) is a synthetic chemical found in wide range of consumer products and consumables that humans are exposed to. The aim this study was to determine BPA contamination levels 51 milk samples sold the Rio de Janeiro Metropolitan Region, Brazil. detected (≥limit detection, LOD) five analyzed (9.8%) quantified quantification, LOQ) two (3.8%). estimated daily intake (EDI) for children ...

OBJECTIVE To measure nutrient intake adequacy of vitamin/mineral supplement users and nonusers aged 51 years and older, determine the efficacy of supplement practices in compensating for dietary deficits, and identify predictors of supplement use. DESIGN Analyses of two 24-hour recalls, demographic variables, and attitude questions collected during the Continuing Survey of Food Intakes by Ind...

This study estimated the non-carcinogenic health risk of Pb, Cu, Cd, Zn via dietary intake in urban and rural areas Baia Mare city, northwestern Romania, a former mining area. A total 230 food items grouped ten categories (meat animal organs, meat-derived products, fat, eggs, dairy, bread, corn flour, potato, vegetables, fruits) 32 water samples were collected analyzed for Cd using atomic absor...

We discuss the problem of assessing nutrient intake relative to the tolerable upper intake levels (UL) for the nutrient proposed by the Institute of Medicine and focus on 2 important topics: the estimation of usual nutrient intake distributions and the extent to which intakes above the UL can be considered risky. With the information that is currently available for most nutrients, it is not pos...

I intake and I deficiency were investigated in thirty vegans (eleven males and nineteen females) consuming their habitual diet. I intake was estimated using the chemical analysis of 4 d weighed duplicate diet collections. The probability of I-deficiency disorders (IDD) was judged from the measurement of urinary I excretion in 24 h urine specimens during the 4 d. There was wide variation in I in...
