Foods are an extremely diverse group of products that are often supplemented with additional items and sometimes contaminated with harmful substances. The concept of food analysis has grown in ...complexity as a result of international regulations and legislation, consumer demand, and globalization of the food market. Thus it has become an absolutely necessary task to trace a detailed description of a food, in terms of its nutritional value, chemical composition, bioactivity and toxicological aspects. Food analysis pushes research towards more advanced, sensitive and environmentally friendly methodologies. Sample preparation is a crucial part of the analysis. A successful food analysis cannot be achieved without an appropriate, convenient and reliable sample preparation strategy. On the other hand, in the last few years, a considerable variety of analytical methods applied to food analysis has been made available at the same rate as the increasing concern about food safety. The choice of the analytical methodology depends on various factors, such as nature of sample, goal of the analysis, and the availability of human and instrumental resources. In this chapter, current atomic emission‐based sampling methodologies and sample preparation techniques used for food analysis and the advantages and drawbacks of each one are discussed. In addition, two elemental spectrometric determination techniques, flame atomic emission spectrometry (FAES) and inductively coupled plasma optical emission spectrometry (ICP‐OES), their fundamentals, operational and experimental considerations regarding elemental analysis in food samples, and applications will be described.

Chemokinesis and chemotaxis were measured in polymorphonuclear cells (PMN) from 51 children aged 1 to 8 years old, of either sex. Case group--41 non-allergic asthmatic children with chronic relapsing ...upper airways infections, diagnostic criteria were history of wheezing associated to an upper airways infection episode and negative skin tests.
10 healthy children. A sample of 10 ml of peripheral venous blood was drawn. PMN were incubated with Hank's solution to measure chemokinesis and with C5a and Staphylococcus aureus extract to measure chemotaxis. Chemokinesis values in healthy control children and in patients with non-allergic bronchial asthma were of 46.0 +/- 7.1 vs 23.8 +/- 6.1 microns (p < 0.01). C5a-stimulated chemotaxis values in healthy control children and in patients with non-allergic bronchial asthma were of 91.0 +/- 21.3 vs 92.3 +/- 21.0 microns (ns), and Staphylococcus aureus extract-stimulated chemotaxis values in healthy control children and in patients with non-allergic bronchial asthma were of 97.0 +/- 22.4 vs 92.0 +/- 23.0 microns (ns). These results suggest that PMN from children with non-atopic asthma have reduced chemokinesis. After a chemotactic stimulus with C5a and bacterial extract, leukocyte motility is corrected and reach similar values to that present in healthy children.
