title: Radiostrontium levels in foodstuffs: 4-Years control activity by Italian reference centre, as a contribution to risk assessment.
abstract: (90)Sr is considered an important contaminant relating to food supply chains. In this study, 176 liquid and 260 solid foods, were analysed in order to quantify (90)Sr. Through ruggedness tests, the application field of radiochemical methods used was extended successfully to all most important types of foodstuffs. Regarding liquid matrices, milk samples resulted the most important indicator about (90)Sr contamination, with mean (90)Sr activity concentration equal to 0.058BqL(-1). Among other liquid foods, wine/spirits and livestock watering resulted the most contaminated, with mean contamination levels equal to 0.022 and 0.035BqL(-1), respectively. Concerning solid matrices, cheeses produced from sheep's milk and animal feeds resulted the most contaminated (mean levels: 1.237 and 1.557Bqkg(-1), respectively). Meat products and seafood showed contamination levels not significant within this survey; while, among vegetables, cacao/chocolate and spices resulted in contamination levels comparable with those of cheese obtained from milk of cows origin.
