Importante
studio internazionale pubblicato da un gruppo di ricercatori di livello,
che conferma ( essendoci già una abbondante bibliografia a riguardo ) un dato molto rilevante.
Nei lavoratori esposti a basse frequenze in
ambito lavorativo ( ma potremmo tranquillamente traslarlo per quanto
concerne le emissioni degli elettrodotti) vi è un incremento del rischio
di mortalità del 55% di Sclerosi Laterale Amiotrofica (SLA).

Abstract
Amyotrophic lateral sclerosis
(ALS) has been associated with exposures in so-called 'electrical occupations'.
It is unclear if this possible link may be explained by exposure to extremely
low-frequency magnetic fields (ELF-MF) or by electrical shocks. We evaluated
ALS mortality in 2000-2008 and exposure to ELF-MF and electrical shocks in the
Swiss National Cohort, using job exposure matrices for occupations at censuses
1990 and 2000. We compared 2.2 million workers with high or medium vs. low
exposure to ELF-MF and electrical shocks using Cox proportional hazard models.
Results showed that mortality from ALS was higher in people who had medium or
high ELF-MF exposure in both censuses (HR 1.55 (95% CI 1.11-2.15)), but closer
to unity for electrical shocks (HR 1.17 (95% CI 0.83-1.65)). When both
exposures were included in the same model, the HR for ELF-MF changed little (HR
1.56), but the HR for electric shocks was attenuated to 0.97. In conclusion,
there was an association between exposure to ELF-MF and mortality from ALS
among workers with a higher likelihood of long-term exposure.
