Bisphenol A contamination in soft drinks as a risk for children's health in Italy.

Bisphenol A (BPA) was determined in sugary carbonated, non-carbonated and milk-based beverages, through HLPC-fluorescence detection and confirmed by LC-MS/MS, in a selection of brands that are mostly consumed by Italian children. The daily intake was determined through the WHO budget method (BM). BPA was found at detectable levels in 57% of carbonated beverages, in 50% of non-carbonated and in 100% of milk-based beverages.

Occurrence of NDL-PCBs, DL-PCBs, PCDD/Fs, lead and cadmium in feed and in rainbow trout (Oncorhynchus mykiss) farmed in Italy.

The safety of farmed rainbow trout (Oncorhynchus mykiss) is correlated with the quality of the production process. Polychlorinated biphenyls (PCBs), dioxins (polychlorinated dibenzodioxins and furans - PCDD/Fs), and heavy metals such as lead and cadmium were investigated because they can represent a risk for the consumer. The levels of these compounds in water, feed and specimens of trout farmed with two different feeds (A and B) were assessed.

Di(2-ethylhexyl)phthalate (DEHP) and di-n-butylphthalate (DBP) exposure through diet in hospital patients.

Ready-to-eat packed meals intended to hospital patients were studied over a two-weeks period to measure the contents of di-(2-ethylhexyl) phthalate (DEHP) and di-n-butylphthalate (DBP) and to evaluate their daily intake by total diet. The packaging consisted of polyethylene terephthalate (PET) dishes sealed with polypropylene (PP) foil. The DEHP mean concentrations in total meals varied from 0.

Children's exposure to Di(2-ethylhexyl)phthalate and dibutylphthalate plasticizers from school meals.

Packed school meals for children 3-10 years old were studied to evaluate the levels of di(2-ethylhexyl)phthalate (DEHP) and di-n-butylphthalate (DBP) and the influence of the packaging process on meal contamination, and their contribution to daily intake was estimated. The packaging consisted of polyethylene-coated aluminum (PE/Al) dishes thermally welded by a polyethyleneterephthalate-coated aluminum (PET/Al) foil. Foodstuffs before processing were analyzed, too.

Cadmium accumulation and antioxidant responses in Sparus aurata exposed to waterborne cadmium.

Cadmium (Cd), a nonessential trace element, is rapidly accumulated by most living organisms and subsequently exerts its toxicity at different molecular levels. This study exposed gilthead sea bream (Sparus aurata) to waterborne 0.1 mg/l Cd for 11 days and investigated the Cd accumulation pattern, lipid oxidation, and response of antioxidant defences.

Assessment of the dietary habits and polycyclic aromatic hydrocarbon exposure in primary school children.

Thirty Italian children, 7-9 year aged, living in Naples were investigated on their dietary habits and on polycyclic aromatic hydrocarbon (PAH) exposure by a food diary-questionnaire and one week duplicate diet sample analyses. Daily total food consumption mean value was 632 +/- 215 g day(-1), median value 613 g day(-1). The daily energy intake and the diet composition meanly agreed with the official guidelines for the Italian children.

Survey of lead, cadmium, mercury and arsenic in seafood purchased in Campania, Italy.

Lead, cadmium, mercury and arsenic were surveyed in fresh catch, farmed and frozen marine fish, cephalopods and mussels marketed in Campania (Italy), and the population's weekly intake from seafood was assessed. A total of 162 specimens of fish and cephalopods and 30 pools of mussels were analyzed. Pb levels in fresh catch species ranged between <20 and 689 ng/g; in farmed from <20 to 438 ng/g and in frozen from <20 to 541 ng/g.

Polychlorinated biphenyls, organochlorine pesticides, and polycyclic aromatic hydrocarbons in wild, farmed, and frozen marine seafood marketed in Campania, Italy.

Polychlorinated biphenyls (PCBs), organochlorine pesticides, and polycyclic aromatic hydrocarbons (PAHs) were detected in fresh-catch, farmed, and frozen marine fish marketed in Campania, Italy. Additionally, polychlorobiphenyl congeners were found: six were non-dioxin-like (NDL-PCB) (IUPAC no. 28, 52, 101, 138, 153, and 180), and one was dioxin-like (DL-PCB) (IUPAC no.

Occurrence of polychlorobiphenyls in buffalo mozzarella cheese from Campania (Italy).

Buffalo milk and mozzarella cheese produced in the Caserta and Salerno areas in Campania region have been investigated on the presence and the levels of polychlorobiphenyls (PCBs). Seven congeners, six non dioxin-like (NDL-PCBs nos. 28, 52, 101, 138, 153 and 180) and one dioxin-like (DL-PCB n.

Monitoring of polychlorinated biphenyl contamination and estrogenic activity in water, commercial feed and farmed seafood.

We evaluated the concentration and congener distribution of seven "target" polychlorinated biphenyls (PCBs) present in water collected in different aquaculture farms of the Mediterranean area, commercial feeds, and farmed seafood. PCBs were present in feed and in tissues of all the analysed organisms at levels ranging from 1.96 ng g(-1) to 124.

Multipathway polycyclic aromatic hydrocarbon and pyrene exposure among children living in Campania (Italy).

Multipathway exposure to polycyclic aromatic hydrocarbons (PAHs) and Pyrene (Py) was studied among children ages 7-9 living in two areas of the Campania Region (South-Italy) classified as urban and rural. During five consecutive days PAHs and Py were detected in air samples from outdoors, indoors (school and home), individuals at inhalatory levels, and in food and beverages (defined as food) consumed daily by each child. 1-hydroxypyrene (1-OHP) was detected in children's urine.

Estrogen-like activity of seafood related to environmental chemical contaminants.

Background: A wide variety of environmental pollutants occur in surface waters, including estuarine and marine waters. Many of these contaminants are recognised as endocrine disrupting chemicals (EDCs) which can adversely affect the male and female reproductive system by binding the estrogen receptor and exhibiting hormone-like activities. In this study the estrogenic activity of extracts of edible marine organisms for human consumption from the Mediterranean Sea was assayed.

Natural co-occurrence of deoxynivalenol and fumonisins B1 and B2 in Italian marketed foodstuffs.

A survey was performed to obtain the frequency and levels of contamination by deoxynivalenol (DON) and fumonisins B1 and B2 (FB1, FB2) mycotoxins in Italian marketed foods. Of 202 samples investigated, including raw materials and processed cereal foods (bread, pasta, breakfast cereals, biscuits, baby and infant foods), 84% were contaminated with DON at levels from 0.007 to 0.

Evaluation of benzene exposure in children living in Campania (Italy) by urinary trans,trans-muconic acid assay.

The urinary benzene metabolite trans,trans-muconic acid (MA) was determined in 144 children living in Campania (Italy): 92 from Naples (1,300,000 inhabitants), designated as an urban source, and compared to 52 from Pollica (300 inhabitants), considered a rural, background exposure for benzene. The children participating in the study were tested by an anonymous questionnaire about the possible sources of exposure to benzene. Quantifiable levels of MA were found in 63% of the urine samples analyzed.

Alkyltins in farmed fish and shellfish.

A study to update dibutyltin (DBT) and tributyltin (TBT) residues in farmed fish and shellfish (Mytilus edulis) was carried out 4 years after the adopting of the restricting regulation of the antifouling uses of organotins in Italy. DBT and TBT were simultaneously extracted from farmed fish and shellfish (M. edulis) and from free living specimens, used as control, purchased from retail stores or fishermen in the province of Naples (Italy), and detected using a capillary gas chromatograph equipped with a flame photometric detector (GC-FPD).

Lead in human blood from children living in Campania, Italy.

Blood lead (PbB) levels were determined in children living in Campania (in Naples and in a rural zone in the district of Caserta). Atmospheric lead (PbA) concentration in these considered areas was monitored for 1 yr (1993-1994). The children tested were questioned about common sources of lead, other than atmospheric, relating to their living and dietary habits.

Evaluation of the selenium content of the traditional Italian diet.

Food samples and ready-made meals from the traditional Italian-type diet were analysed for selenium content. The average Se content varied in food samples from 7 micrograms/kg w/w (fresh fruit) to 226 micrograms/kg w/w (fish). The highest average contents were obtained in the animal products and in legumes.
