“…Neutrophils and haemoglobin levels were higher in LPG plant workers that had 5 years and above exposure. These observations were consistent with the findings of Ezejiofor et al, (2014). Also, sodium levels were higher in LPG plant workers with 1 year exposure, followed by 2-3 years, 4-5 years and 5 years and above.…”

“…Serum urea values were higher in LPG plant workers with 4-5 years of exposure while serum creatinine levels were higher also higher within 4-5 years of exposure. The observations in serum sodium, creatinine, urea and creatinine as regards the variations in the age groups and years of exposure were consistent with the findings of Ezejiofor et al, (2014).…”

Liquefied Petroleum Gas (LPG) plant workers are exposed to a number of hydrocarbons from handling petroleum and petroleum-based products and this exposure poses a major health challenge to these workers. This study was designed to evaluate the effects of duration of exposure on biochemical and haematological profile in LPG plant workers. A total of one hundred (100) subjects between 20-60 years were recruited for this study which consist of fifty (50) liquefied gas plant workers and fifty (50) non LPG gas plant workers. Blood samples (10ml) were collected from the cubital vein of each subject using sterile needles and syringes into K3-EDTA tubes and plain plastic containers. The biochemical and haematological parameters were analyzed using standard procedures as prescribed by the manufacturers. The results showed that there was significance difference (p<0.05) observed in all the heamatological parameters as compared with the respective controls. However, there was no significant difference ((p>0.05) in neutrophils values obtained as compared with the control. The serum sodium levels were higher in subjects that had one year exposure. Serum potassium was higher in the subjects with 2-3 years of exposure. Urea and creatinine levels were higher in subjects with 4-5 years of experience. AST levels were higher in subjects with one year experience when compared with other years. ALT were higher in subject with 2-3 years exposure. ALP levels were higher in subjects with 4-5 years of exposure while GGT levels were higher in subjects with 5 years of exposure. There was no significant difference (p>0.05) observed in the renal and liver profile within the period of exposure to LPG. However, the total white blood cell count was significantly higher (p<0.05) in subjects with 4-5 years and over 5 years of exposure when compared with 1 year and 2-3 years of exposure while there was no significant difference (p<0.05) observed for other haematological parameters. The results of this study showed that exposure to LPG resulted in significant alterations in haematological parameters. However, exposure to LPG had significant effect only on the total white blood cell count while there was with no significant effect on the renal and liver profile of LPG plant workers.

Objetivou-se identificar as fontes de exposição dos trabalhadores portuários avulsos aos riscos químico, físico e biológico no ambiente laboral, com potenciais para alterações da função respiratória. Estudo de caráter quantitativo, exploratório, com técnica observacional não-participante e direta de trabalhadores de um porto naval do sul brasileiro. A coleta de dados ocorreu de julho a dezembro de 2014, sendo realizadas 87 observações de 66 trabalhadores. Realizou-se análise descritiva dos dados, por meio de frequência absoluta e percentual. As fontes predominantes de exposição ao risco físico foram frio, umidade e radiação não ionizante. As fontes de exposição ao risco químico decorreram da movimentação de grãos, fertilizantes e gases combustíveis, e o risco biológico observado foi a presença de pombos. O trabalhador portuário está exposto a fontes de riscos ocupacionais à saúde respiratória que variam conforme as cargas, atividades laborais e locais de trabalho.

“…Table 2 shows that the expert familiarity and authority coefficients of the four main indicators are greater than 0.65 and 0.75, respectively. In general, if the authority coefficient of each index participant is greater than 0.7 [20], then the project of the index system can be regarded to be with high credibility. That is, the higher the expert authority score, the higher the project consensus proposed.…”

“…Therefore, based on the full consideration of the mechanisms and features of occupational hazards, the study aims to establish a comprehensive evaluation system for hazardous working environments from certain aspects, such as inherent occupational hazards, offset factors of occupational hazards and workers' health conditions. In addition, we collected data on advanced experience from domestic and foreign assessment involving workplace occupational hazards [17][18][19][20][21]. Ultimately, the study intends to focus on formulating a comprehensive, dynamic, objective, effective as well as scientific system to mirror the status on the prevention and control of occupational hazards in the iron and steel industry based on the modified Delphi technique.…”

The study designs a comprehensive evaluation system for the prevention and control of occupational hazards, calculates its weight coefficient, and provides a potential strategic and effective tool for the scientific evaluation of occupational hazards in the iron and steel enterprises. The system was established through induction and analysis of relevant literature, personal interview, theoretical analysis, Delphi expert consultation, and special group discussions. Using an improved analytical hierarchy process fuzzy comprehensive evaluation model and on the basis of the improved Delphi expert investigation, the weight of the operability comprehensive evaluation index system is constructed. A three-level index system is established on the basis of harmful factors of occupational activities, health status of employees, protection facilities of occupational hazards, occupational health management, and so on. The index system structure is 4-20-95, and the weight coefficients of the four dimensions are 0.2516, 0.2428, 0.2550, and 0.2506. The recovery rate of the questionnaire was 82.5%, 100.0%, and 100.0%. The effective rates were 75.0%, 100.0%, and 100.0%. Conversely, the expert authority coefficients of the four dimensions are 0.875, 0.769, 0.832 and 0.800. Results show that the consistency factors of the four dimensions are statistically significant. Cronbach’s α coefficient, standardized Cronbach’s α coefficient, and split-half reliability of the comprehensive evaluation index system are 0.959, 0.950, and 0.810, respectively. After factor analysis, four common factors were extracted on the basis of expert opinions, and the cumulative variance was 63.1%. The comprehensive evaluation system for the prevention and control of occupational hazards in the iron and steel enterprises proposed by the study is relatively complete and reasonable.
