Exposure assessment to suggest the cause of sinusitis developed in grinding operations utilizing soluble metalworking fluids.
A worker who ground the inner parts of camshafts for automobile engines using water-soluble metalworking fluid (MWF) for 14 yr was diagnosed with sinusitis. We postulated that the cause of sinusitis might be associated with exposure to microbes contaminating the water-soluble MWF used in the grinding operation. To uncover responsible agents for this case of sinusitis, a quantitative exposure as...

ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...
15 صفحه اولHealth risks from exposure to metal-working fluids in machining and grinding operations.
Metal-working fluids (MWFs) are used in machining and grinding operations to cool the tool and work, reduce the friction between the tool and work, improve the surface integrity of the work piece, and increase tool life and productivity. Health problems have been reported among workers exposed to MWFs, including incidences of respiratory, digestive and skin cancers, and increased rates of cough...
متن کاملMicrobial and endotoxin contamination of water-soluble metalworking fluids.
UNLABELLED The present study is a part of a larger project on assessment of exposure to biological agents and respiratory health effects among metal workers. OBJECTIVES The aim of this study was to evaluate the level of microbial contamination of metalworking coolants as a potential source of harmful biological agents in three different metal industry plants in Poland. MATERIAL AND METHODS ...
