The first phase of transport of forest products (skidding) in Serbia is usually performed by skid trails with adapted agricultural tractors. The educational base ?Goc - Gvozdac? compartment 21 was the selected object of this research. Data recording was carried out in June 2011. The vehicle driven by the driver was an IMT 565 DV tractor. The organizational form of work was 1T + 1P (tractor driver and assistant). The microphone of a Bruel & Kjaer 4189 noise measuring instrument was mounted on the helmet of the tractor driver in accordance with the ISO 9612: 2012 standard. The recording was performed with a Bruel & Kjaer 2250 instrument. The values of the following parameters with appropriate filters: LAeq (dB(A)), LAIeq (dB(A)), LCpeak (dB(C)), LZeq (dB) were measured. The measured exposure of the workers to noise was the highest in the course of the main productive time (empty or full drive). It was found that the eight-hour exposure to noise of the driver (88 dB (A)) exceeds the limit value of daily exposure according to European legislation. The results show that it is necessary for drivers to use hearing protection equipment when transporting wood with the studied transportation vehicle.

Sea fishing is one of the sectors with the highest risk of illness and work-related accidents. The purpose of the study is to evaluate the exposure of fishing workers to three major risks: biomechanical overload, noise, and whole-body vibrations. We used common methods and measurement tools in the field: observational video analysis, questionnaires, and direct measurement. Noise and vibrations levels were measured aboard five boats belonging to the main fishing communities of Southern Italy. The random sample consisted of 310 workers, of whom 108 agreed to complete a questionnaire to collect data on the perception of occupational risk and self-perception of health conditions. We found that fishermen had a high prevalence of osteoarticular pathologies (42%) and that the biomechanical overload risk is mainly related to handling manual loads. Furthermore, the results indicate that the levels of weekly noise exposure exceed the exposure limit value of 87 decibel A (dBA) for fishing workers, and that the most noisiest area is the engine room. Exposure levels to whole-body vibrations were below <0.5 m/s2. Knowledge on occupational hazards and health effects in the fisheries sector should be used to develop ship technology, raise awareness of the correct use of personal protective equipment, and improve health surveillance of these workers.
