The excessive amounts of cadmium and lead in food chain can cause health problems for humans and ecosystem. Rice is an important food in human diet. Therefore this study was conducted in order to investigate cadmium and Lead concentrations in seed rice (Oryza saliva) of paddy fields in southwest of Iran. A total of 70 rice seed samples were collected from paddy fields in five regions of Khuzest...

Fruit and vegetables contain carotenoid pigments, which accumulate in human skin, contributing to its yellowness. This effect has a beneficial impact on appearance. The aim was to evaluate associations between diet (fruit, vegetable and dietary carotenoid intakes) and skin color in young women. Ninety-one Caucasian women (Median and Interquartile Range (IQR) age 22.1 (18.1-29.1) years, BMI 22.9...

Organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) were measured by a gas chromatography-mass spectometry (GC-MS) in some edible fish from Huairou Reservoir and Gaobeidian Lake in Beijing, China. The concentrations of OCPs and PCBs were higher in fish (except Misgurnus anguillicaudatus) from Gaobeidian Lake than in those from Huairou Reservoir. The average concentrations of H...

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...

Studies on the intakes of intense sweeteners in different countries published since the author's previous review in 1999 indicate that the average and 95th percentile intakes of acesulfame-K, aspartame, cyclamate and saccharin by adults are below the relevant acceptable daily intake (ADI) values. Fewer data are available for the newer sweeteners, sucralose and alitame, and because they are rece...

OBJECTIVE To determine the relative validity of a 3 d estimated food record (EFR) used to assess energy and nutrient intakes in toddlers, using a 3 d weighed food record (WDR) as the reference method. DESIGN Parents reported the food and beverage intakes of their children using an EFR concurrently with a WDR over three consecutive days. Estimation of mean differences, Spearman correlation coe...

Deoxynivalenol (DON) is produced by Fusarium graminearum and is one of the most commonly occurring trichothecenes. Vegetarians are alleged to be a high-risk group for DON exposure due to high intakes of cereals susceptible to the growth of the mycotoxin. This study provides the levels of DON and de-epoxi Deoxynivalenol (DOM-1) in urine analysed by liquid chromatography-mass spectrometry (LC-MS)...

Aspartame is an intense sweetener which is increasingly used in the UK. It is registered at an acceptable daily intake (ADI) of 40 mg/kg, although there are no previous data relating to the metabolism of aspartame in older people. Twelve young and 12 elderly volunteers each received a single dose of approximately 40 mg/kg of aspartame. Baseline concentrations of phenylalanine (the main metaboli...

The increase of fruit and vegetable (F&V) intake contributes to the prevention of chronic diseases, but could also significantly increase pesticide exposure and may thus be of health concern. Following a previous pesticide exposure assessment study, the present study was carried out to determine actual levels of pesticides within 400 g of F&V intake and to evaluate consumer risk. Forty-three Ac...

Four hundred and seventy-two pasta samples were collected from long retail distribution chain sales points located in North, Central and South Italy. Representative criteria in the sample collection were followed in terms of number of samples collected, market share, and types of pasta. Samples were analysed by an accredited HPLC-UV method of analysis. The mean contamination level (64.8 μg/kg) ...
