Lifestyle influence on trace element contents in human scalp hair of young residents in different urban contexts. Preliminary results.
2010
A causal relationship between earth material and human health, although not always proven, is highly plausible because many chemical elements in rocks and soils are directly inhaled by respiration or transmitted, via air, water and vegetation, into food chain and then to human body. It is well known that metals and metalloids may result essential to biochemical and physiological functions, but it is also well known that health problems may derive from either dietary deficiencies or excesses. Among the techniques employed to assess the exposure of living organisms to metals and metalloids present in the environment, the human biomonitoring has attracted the attention of investigators over th…
Coverage intervals for trace elements in human scalp hair are site and also gender-specific
2015
Hair analysis is a powerful tool for assessing human exposure to metals and metalloids (MM). The basis for interpreting laboratory results lie on the use of coverage intervals (CI), computed between the 0.025 and 0.975 fractiles, from a well-defined group of reference individuals reflecting normal and healthy people. A critical point in efficient use of CI, when used for comparative decision-making processes, forensic and clinic considerations, is constituted by confounding factors as the specific living site of study population and gender of participants. Our study aims to demonstrate that hair levels of trace elements are site specific and also gender specific. We have taken into account …

Trace elements in hair of urban schoolboys: a diagnostic tool in environmental risk assessment.
2011
Hair analysis may represent a means to quantify the relationship between human exposure to metal contamination and the environmental conditions of workplaces or residence sites. Hair are stable and their composition does not change over short time period. Furthermore, sampling procedure is very easy, requires no specific professional skills, is painless and non-invasive. 334 hair samples were collected from Caucasian children 11-13 years old, of both genders, without colored or treated hair, living in several Sicilian towns characterized by different geochemical environments: urban (Palermo), volcanic (Etna), mining area (Antillo-Fiumedinisi), industrial site (Pace del Mela), uncontamined a…

Influence of industrial activity on metal and metalloid contents in scalp hair of adolescents
2015
Petrochemical industries represent a controversial although important economical resource. They offer a great deal of job opportunities producing also a development of several areas. However, such kind of industrial plants are responsible for the change of the environmental background through the emission of toxic pollutants such as metalsmetalloids and organic compounds. People living in cities close to such industrial plants are particularly exposed to a severe environmental decline, which implies the deterioration of the quality of air, soil, water and food with the consequent human health concerns. The municipalities of Gela (GL) and Pace del Mela (PM), located respectively along the Me…

Can we consider a natural environment always of high quality and adequate to protect population from potential risks of health threats?
2013
The question posed in the title arise because the current knowledge suggests that there are important, both beneficial and adverse, relationships between natural environment and human health. The human body obtains metals and metalloids from diet, some of which are derived from local foodstuffs and municipal water supplies, and it is therefore plausible that areas characterized by various types of bedrock and superficial materials, upon which food is grown and water drained, provide different availabilities of trace elements. The present study aimed at elucidating whether the degree of human exposure to trace elements is subject to changes in local environmental factors. This hypothesis was…
