BACKGROUND: The workplace is affected by poor lifestyle habits that can cause alterations in the quality of life (QOL) of the employees. OBJECTIVE: To evaluate the quality of life and the cardiovascular risk factors in employees of a business. Relate the quality of life with the variables of cardiovascular risk, gender and work sector. METHOD: 41 employees were evaluated (30 females and 11 males) aging between 18 and 54 years (mean 27.4 ± 8.9 years). A protocol was used with: personal data, personal background, physical examination (anthropometry) and the WHOQOL-bref questionnaire to evaluate the QOL. Statistical analysis was completed by the Chi-squared test and Sperman’s rank correlation, with a significance of 5%. RESULTS: We found 31(75.6%) sedentary; 16(39.0%) excess weight; 2(4.9%) smokers; 9(22.0%) alcohol consumers and 25(61.0%) family history. We also found 13(31.7%) overweight/low risk and 3(7.3%) obese/moderate risk. The best score on the WHOQOL-bref was on physical health (72.9), and the worst on environment (61.3) and mean score of 69.5 for total QOL. Male employees presented greater scores on all domains, but this association had a non-significant result. There was positive correlation between the physical and psychological domains with the environment and total QOL. CONCLUSION: The employees presented important cardiovascular risk factors like sedentary lifestyle, family history, excess weight and alcohol consumption. The employee’s QOL is considered satisfactory in the perception of health; the best QOL being in the physical domain and the worst in the environment. Change measures are suggested to the company for the cardiovascular risk factors detected.

The petrochemical industry represents a sector of intense activity, in constant expansion and great economic importance for Brazil. In order to be used in various human activities petroleum needs to suffer a refinement process that, besides requiring large amounts of water, produces large amounts of wastes, which are discharged in hydric resources. Petroleum is a complex mixture mainly comprised by hydrocarbons, many of them are recognized as toxic chemicals, which are able to induce a considerable environmental pollution. Since water is an important resource for the maintenance of ecosystems and is also the final receiver of effluent discharges of the petroleum industry, there is an imminent need to monitor, constantly, the hydric resources that are influenced by this industrial activity, so that it can be ensured the environmental health. This study aimed, mainly, to analyze the quality of water samples derived from refinement process performed of the largest petroleum refinery in Brazil (REPLAN), in distinct steps of the industry treatment, and waters of rivers associated to its activity. Micronuclei and Nuclear Abnormalities tests were performed in erythrocytes of the fish species Oreochromis niloticus exposed to water samples derived from refinery use and to rivers under the influence of their effluents, in order to evaluate its possible toxic, genotoxic and mutagenic effects. The results obtained show that the treatment carried out by the refinery, during the evaluated periods, was effective, since the substances present in the water samples did not induce significant genotoxic and/or mutagenic alterations in the genetic material of the test organisms. On the other hand, when the substances present in the refinery effluent mix with the ones derived from other industrial activities developed upstream of this industry, the resultant compound, in some periods, presented genotoxic potencial, characterized by a rise of erythrocytic...
