This research presents a study of environmental monitoring at different sampling sites from the Metropolitan Area of the Valley of Toluca (MAVT), Mexico, using mosses (Leskea angustata(Tayl.) andFabronia ciliaris(Brid.)) and soil samples. The epiphytic mosses and soils were sampled in two campaigns within two periods of the year, a rainy and dry-cold season. The selected sampling sites included urban regions (UR), transitional regions (TR), and protected natural areas (PA). The samples were analyzed by the Instrumental Neutron Activation Analysis (INAA) to determine As, Cr, Hg, and Se principally. However, due to the versatility of the analytic technique used, other elements including Cs, Co, Sc, Sb, Rb, Ce, La, Eu, and Yb were also detected. Statistical analysis (As, Cr, Hg, and Se) was carried out with principal components and cluster analysis methods; this revealed that a good correlation exists between metal content in mosses and the degree of pollution in the areas sampled. The obtained results in mosses showed that the concentrations of As, Cr, Co, Cs, Rb, Ce, La, and Yb increased with respect to the concentrations obtained during the first sampling, whereas Se, Sc, Sb and Eu, concentrations were decreased. For As and Hg, the concentrations were similar in both sampling periods. The soil samples present the most significant concentration.

Abstract Scalp-hair samples from 40 multiple sclerosis patients and 42 controls were analyzed by neutron activation analysis, with a SLOWPOKE reactor as the neutron source. Ag, Al, As, Au, Ba, Br, Ca, Cl, Cu, l, K, Mg, Mn, Na, S, Sb, Se, Sr, V, and Zn were determined in samples of about 0.1 g. Highly significant differences (99% confidence) were observed between the two groups in concentrations of Cu, l, Mn, S, Se, and V.

Abstract In the present work, zinc levels were measured in scalp hair and fingernails in order to identify potential risk factors for breast cancer. The samples were collected from 40 Algerian breast cancer female patients and from 20 normal subjects matching the same age range. The concentration of zinc was analyzed using Instrumental neutron activation analysis technique (INAA). In scalp hair samples it was found in the range 119–792 μg/g for the normal subjects and in the range 82–806 μg/g for the patients, with an increase rate of 10.9%. The range of concentration of zinc in fingernails was found between 89 and 247 μg/g for normal subjects and between 75 and 276 μg/g for the patients with an increase rate of 2.5%. The influence of age on zinc concentration was also investigated. The obtained results show some consistency with those obtained by other groups.
