Abstract

Project paper (B.Sc.(Environmental & Occupational Health)) - Universiti Putra Malaysia, 2014. Introduction: Metalworking fluids (MWFs) are commonly used in machining industry during metal working process such as cutting, turning, milling, drilling and grinding. These , fluids were used extensively as industrial lubricants to provide lubricate cool metalworking operation by reducing friction at tool-work piece interfaces and carrying away heat (HSE, 201 1). Most commonly used metalworking fluids in Malaysia industry is water-based metalworking fluids (MWFs), hence the exposure of microbial contaminant from the fluids may induce health impact in workers. Machining's workers are most exposed to the I contaminant of metalworking fluids (Duchaine et al., 2012) Objective: To determine whether IgG antibodies was the determinants of occupational exposure for the microbial contaminants of metalworking fluids. Methodology: This cross sectional study were carried out on 138 machining workers who were exposed to metalworking fluids (MWF) had been employed for , 6 months and above and age between 20-58 years old (Lewis, 2001). The respondent were required to answer the questionnaire to obtain the data information regarding on the study and 30 minutes were given to complete the questionnaire. All respondent who meet the inclusion criteria were undergo blood sampling procedure. 2 ml blood were drawn from the cubital to be tested for the serum 1gG level in blood. The microbial assessment were determined by MWF sampling and microbial air sampling. DUO SAS SUPER 360™ were used 1 to to identify the bacteria and fungi count in the environment. The data were analyses by using SPSS software. Result and Discussion: This study indicates that , the total mean value for the environmental bacteria and fungal in all job section were 285.83cfu/m³ and 231.2cfu/m³ respectively. Whereas, the total means value for microbial contamination in bulk were 37916.7 cfu/m³ (bacteria) and 38833.3 cfu/m³ (fungal). The total mean value of the respondent's 1gG in all job section was 13.79 g/litre. The level of environmental bacteria had a significant correlation with the level of IgG antibodies in the blood (p=0.003). There were also a significant relationship between BMI (p=0.044), work duration (p=0.014), smoking (p=0.014)and environmental contaminants (0.049) with the level of IgG. Conclusion: There were significant correlation between the level of IgG antibodies and microbial contaminants of metalworking fluids in metal working process. Besides that, there were significant relationship between work duration, smoking, BMI and environmental contaminants with the level of IgG. Keywords: Metalworking's fluids, IgG Antibodies, Microbial Contaminants
