Sound is considered as a pollutant when it exceeds undesirable limits for the recipient. One of the significant environmental problems associated with industries is noise pollution generated by machinery. The main objectives of this study were to measure noise levels generated by machinery that the workers were exposed to at five industrial facilities in the State of Kuwait. Also, to assess if these levels were within acceptable standards, for Kuwait lacks environmental standards for such a pollutant. To achieve the objectives of the study two food manufacturing companies, a cement-brick making plant, a furniture factory and a car washing facility were selected for the purpose of the research.The study showed that workers operating machinery at the five facilities were exposed to high noise levels without any kind of ear protection. Noise levels recorded during the study were very high and exceeded the British Noise at Work Regulations of 1989. In Kuwait there are no regulations to abate noise in the working environment and workers are not required to wear ear protective muffs. The results of the study indicate that, the concerned environmental and health organisations in Kuwait should be compelled to establish noise level standards and controls to safeguard the health of workers and the public at large.  相似文献

Antioxidants and plant products are reported to reduce the genotoxic damage of steroids. In our present study we have tested different dosages of nordihydroguaiaretic acid (NDGA) against the genotoxic damage induced by ethynodiol diacetate in the presence of S9 mix. Treatments with nordihydroguaiaretic acid (NDGA) results in the reduction of the genotoxic damage. A significant decrease was observed at all the tested doses of NDGA in sister chromatic exchanges of number of abnormal cells. The results suggest a protective role of NDGA against the genotoxic damage.  相似文献

• PAM degradation in thermophilic AD in comparison with mesophilic AD. • PAM degradation and its impact on thermophilic and mesophilic AD. • Enhanced methane yield in presence of PAM during thermophilic and mesophilic AD. • PAM degradation and microbial community analysis in thermophilic and mesophilic AD. Polyacrylamide (PAM) is generally employed in wastewater treatment processes such as sludge dewatering and therefore exists in the sludge. Furthermore, it degrades slowly and can deteriorate methane yield during anaerobic digestion (AD). The impact or fate of PAM in AD under thermophilic conditions is still unclear. This study mainly focuses on PAM degradation and enhanced methane production from PAM-added sludge during 15 days of thermophilic (55°C) AD compared to mesophilic (35°C) AD. Sludge and PAM dose from 10 to 50 g/kg TSS were used. The results showed that PAM degraded by 76% to 78% with acrylamide (AM) content of 0.2 to 3.3 mg/L in thermophilic AD. However, it degraded only 27% to 30% with AM content of 0.5 to 7.2 mg/L in mesophilic AD. The methane yield was almost 230 to 238.4 mL/g VSS on the 8th day in thermophilic AD but was 115.2 to 128.6 mL/g VSS in mesophilic AD. Mechanism investigation revealed that thermophilic AD with continuous stirring not only enhanced PAM degradation but also boosted the organics release from the sludge with added PAM and gave higher methane yield than mesophilic AD.  相似文献
