Articolo
pubblicato da David Carpenter su come le fonti
di finanziamento influiscono sui risultati delle indagini sui
nessi causali generati dai campi
elettromagnetici a bassa frequenza (come quelli generati da
elettrodotti,centrali di trasformazione da corrente continua in
corrente alternata, Cabine Elettriche, ecc...) e cancro, che
dimostra in modo inequivocabile come, se la fonte di finanziamento
degli studi e' pubblica/governativa, la relazione esposizione=cancro
e' sistematica (leucemia nei bambini, leucemia-carcinoma mammario
maschile e femminile-tumore al cervello negli adulti) mentre al
contrario quando la fonte di finanziamento e' privata (industria)
nessuna associazione e' significativa.
Esattamente
come accade oggi per le esposizioni alle radiazioni ad alta frequenza
(smartphone, stazioni radio base di telefonia, wi-fi,ecc).
Tutto
questo generato dalla mancanza di una legge SUL CONFLITTO DI
INTERESSI su reati ambientali e sanitari, vero grande problema
internazionale che affligge la società odierna per cui non esiste
mai alcun problema/allarme di natura sanitaria.

HIGHLIGHTS
Magnetic field exposure causes childhood leukemia in
government-funded studies.
Magnetic field exposure does not cause childhood
leukemia in industry-funded studies.
Magnetic field exposure increases risk of adult
leukemia, brain and breast cancer.
Steps should be taken to reduce human exposure to
elevated magnetic fields.
ABSTRACT
While there has been evidence indicating that
excessive exposure to magnetic fields from 50 to 60 Hz electricity increases
risk of cancer, many argue that the evidence is inconsistent and inconclusive.
This is particularly the case regarding magnetic field exposure and childhood
leukemia. A major goal of this study is to examine how source of funding
influences the reported results and conclusions. Several meta-analyses dating
from about 2000 all report significant associations between exposure and risk
of leukemia. By examining subsequent reports on childhood leukemia it is clear
that almost all government or independent studies find either a statistically
significant association between magnetic field exposure and childhood leukemia,
or an elevated risk of at least OR = 1.5, while almost all industry supported
studies fail to find any significant or even suggestive association. A
secondary goal of this report is to examine the level of evidence for exposure
and elevated risk of various adult cancers. Based on pooled or meta-analyses as
well as subsequent peer-reviewed studies there is strong evidence that
excessive exposure to magnetic fields increases risk of adult leukemia, male
and female breast cancer and brain cancer. There is less convincing but
suggestive evidence for elevations in several other cancer types. There is less
clear evidence for bias based on source of funding in the adult cancer studies.
There is also some evidence that both paternal and maternal prenatal exposure to
magnetic fields results in an increased risk of leukemia and brain cancer in
offspring.
When one allows for bias reflected in source of
funding, the evidence that magnetic fields increase risk of cancer is neither
inconsistent nor inconclusive. Furthermore adults are also at risk, not just
children, and there is strong evidence for cancers in addition to leukemia,
particularly brain and breast cancer.
