June 13, 2025

The objective of this study is to monitor essential metals including calcium (Ca), copper (Cu), iron (Fe), magnesium (Mg), nickel (Ni), and zinc (Zn), as well as xenobiotics, as well as toxic metals such as arsenic, cadmium, and lead in the hair of boys aged 12-13 from different cities in Salerno province. This preliminary study explores possible relationships between diet and local environmental pollution.


The experimental data showed significant differences in metal levels by sex. Concentrations were determined using atomic absorption spectrometry after washing and mineralization. Notably, lead levels in schoolboys' hair were 1.50 g/g (Salerno) and 1.44 g/g (Solimena), with high nickel levels at Solimena (2.79 g/g) and unsafe arsenic levels at Scafati (2.47 µg/g). Two-way ANOVA indicated a significant interaction between sampling site and sex on arsenic and nickel levels, and effects on cadmium, calcium, copper, lead, and magnesium levels (P<0.05).


Hair metal levels suggest varying exposure to essential and toxic metals among populations. De Prisco P.P. et.al. Biomedical Research 2010; 21 (2): 131-140.

The biological hallmarks of aging are a set of molecular and cellular damage processes that accumulate over time, leading to the functional decline and increased susceptibility to disease that characterize aging. These hallmarks were first described by Lopez-Otin et al. in 2016 and later expanded upon by Kennedy et al. in 2017. They can be categorized into nine primary hallmarks and four integrative hallmarks. Here, we describe the primary hallmarks of aging:
