Also new to the 3 rd edition are newer issues of the day such as nanoparticulate toxicants, second hand smoke, food contamination, lead in toys , and others. As such, the book provides the basics of toxicology in easy to understand language as well as a fuller understanding of the daily insults to which our bodies are subjected.Hinweis: Dieser Artikel kann nur an eine deutsche Lieferadresse ausgeliefert werden.
