Abstrakt
In the Italian agricultural economy, olive cultivation plays a fundamental role, and this
is especially true for the southern regions where almost all cultivation is spread. In Calabria, in
particular, olive cultivation has seen over the last few decades significantly improve the quality
of production also as a result of investments aimed at the creation of new mechanizable plants
and/or the modernization of existing ones; today some areas have got both PDO and PGI
certification.
In the ‘Piana di Gioia Tauro’, located north-west of the Reggio Calabria metropolitan area, olive
growing extends over 20,000 hectares and the presence of centuries-old olive tree is still
widespread. The olive varieties mainly belong to the local cultivars of ‘Sinopolese’ and
‘Ottobratica’, characterized by a remarkable rusticity and high development, perhaps unique in
the world; they reach 20–25 meters high, forming what is called a ‘forest of olive trees’.
The pruning operations are carried out by means of chainsaws of different power and size
whereby, in addition to the previously described difficulties, operators are exposed to prolonged
periods of noise levels. The purpose of this study is precisely to assess the exposure of operators
to this particular olive grove. The aim is to identify the acoustic levels generated by the two
pruning and cross-cutting activities, the risk thresholds and the exposure to which the individual
workers of the two work sites are subjected, giving indications on the appropriate safety distances
to maintain (according to current regulations) compared to noise sources.
