Summary

Due to environmental concerns regarding the phenomenon of climate change and the continuous increase of urban waste, the economy is turning to the development of the waste treatment and recycling sector. This industry has a continued growth in terms of workforce and waste treatment, management, and mechanical recycling facilities. Therefore, the measurement and evaluation of work-related harmful factors in this sector, is very significant, in order to assess and examine the risk is very significant.This master's thesis deals with the analysis in the methodology and assessment of physical health hazards in the field of mechanical waste recycling, with an application example in the Mechanical Recycling and Compost and Landfill unit of the prefecture of Chania. In particular, the factors considered are noise, suspended particulate matter PM10 and odor.For the needs of this master's thesis, on-site measurements of the above-mentioned factors were carried out in December 2019, while even measurement data provided by the Internal Preventive Protection Service ES.Y.P.P. were used. Based on this data, a semi-quantitative determination of the risk was made and the resulting risk maps were created.The method of determining the risk of harmful factors that was applied was based on the deviation of the considered harmful factor from the safe statutory limits and on the severity of the related occupational disease or health damage in general, due to the difficulty of determining the probability. For the odor, the caused dissatisfaction has been evaluated due to the subjectivity in its estimation. Results indicated that the risk and the dissatisfaction in waste treatment and management units related to studied harmful factors, varies greatly in relation to the workplace and the point of measurement. In particular, several points showed a relative high risk due to the continuous exposure of workers to noise based on the equivalent noise level of the eight-hour Leq (dBA) and the concentration of suspended solid particles PM10. For all measurements points, the risk due to worker exposure to high intensity noise of short duration based on the measured peak noise level Lpeak (dBC) was characterized as low. Regarding odor, dissatisfaction was rated mostly moderate or moderate to high in most locations, which was expected due to the unit’s nature. Finally, it is noticed that waste treatment and recycling sector requires continuous monitoring and additional controls and research regarding the development and evolution of the methods of measurement and evaluation of occupational harmful factors in order to assess its overall risk.
