Описание: Murder seems to follow young Tommy McBride everywhere. Only five years after the death of his family, a freak accident on a sheep station sends him fleeing into the wilderness of the Australian outback, the station overseer lying dead behind him with his head smashed on a rock. But Tommy is haunted by more than the death of his family - both he and his brother Billy witnessed a vicious state-sanctioned massacre of the Kurrong people, and they havent seen each other since.When an official inquiry is launched into the slaughter, the successful life that Billy has built for himself is under threat. He desperately needs to find his brother, long

Описание: The migration of substances from packaging to food is a matter of concern for the food safety authorities, and packaging materials constitute a potential source of contaminants to which the consumer will be exposed to through their diet. A huge variety of substances can be present in packaging materials, which could consequently migrate into food and represent a risk to consumer health. Food Contamination by Packaging provides an overview of the main packaging contaminants including Bisphenol A, melamine, phthalates, alternative plasticisers, photoinitiators, perfluorochemicals, saturated and aromatic hydrocarbons (mineral oil saturated hydrocarbons and mineral oil aromatic hydrocarbons) from mineral oils, other bisphenol-related compounds, nanoparticles, primary aromatic amines and nonintentionally added substances. The analytical techniques used for their determination are reviewed. This book will be of interest to students and researchers in universities and research institutions associated with food packaging and, in general, to the food safety sector.
