||Efficacy of personal prevention measures in metal exposure control in welders
||Efficacia delle misure di prevenzione personale nel contenimiento della esposizione a metalli dei saldatori [in Italian]|

||Biological monitoring of welders employed in a power plant showed urinary nickel levels largely exceeding the reference values (Ni-U welders mean=43.2, S.D.=22.1µg/24 h; Ni-U reference values mean=2.7, S.D.=1.4µg/24 h). Subsequently urinary excretion levels of other metals (Cr, Zn, fe, Mn, Cu, Al, Pb) were measured for a more complete assessment of occupational exposure of these subjects; only aluminium and lead were found to slightly exceed the reference values and correlate with urinary nickel levels. As a consequence of these results, some adjustments in personal prevention measures were introduced at the workplace; the subsequent biological monitoring checks showed a progressive reduction in urinary nickel excretion levels over time in all welders.
