Particular attention is given to the D-Roms test (14), which is very simple and has been used also to evaluate the antioxidant activity of some products in patients and healthy subjects. The test is based on the determination of hydroperoxides that are derivatives of oxidized lipids and consequently indicate the OS at cellular level. The test is used for the epidemiological study on metabolic syndrome, in Italy by the European Society of Biological Nutrition.

Observations over the years show that the values listed in column 3 of Table 1, especially those of the bulk elements, stayed rather constant, while the reconunendations of column 2 are subject to change due to an increasing knowledge on the effects of these elements and those of column 4 change due to progress in analytical determinations. Column 6 lists references which provide information for the interested reader about the bioinorganic chemistry, biology, nutrition, and toxicity of these essential metals.

Essential oils are secondary metabolites produced in the plants as volatile aromatic principles. They are colorless and rarely colored and soluble in organic solvents. It is fotmd in all part of the plants and is stored in epidermal cells, trichomes, secretory cells, canals, and cavities. They are extracted by the use of liquid carbon dioxide or microwaves, expression and mainly steam or hydrodistillation process. Due to their biological, nutritive, and pharmaceutical properties, they are more attractive alternatives to synthetic chemical products to protect the equilibrium. 

It is important to highlight that the maximum limit concentration levels are the result of crossed studies regarding chemical, biological, nutritional and medical surveys. As regard merely the chemical aspect, the rules have also followed, in the time, the performances of the instrumental techniques, which have allowed to lower considerably the metal concentrations to determine.

This volume presents a broad coverage of the subject, both from the standpoint of animal species and of the various scientific disciplines involved. Many different domestic and nondomestic animals are discussed by specialists in organic and analytical chemistry, biochemistry, behavior, biology, nutrition, and physiology. Together they provide a clearer understanding of the interrelationships among these various disci-...
