Data obtained suggest that these are the effects on the cardiovascular system of rotogravure workers who are exposed to noise.

These results provide information about the relationship between exposure to arsenic and thyroid markers and may be useful for other categories of outdoor workers who are similarly exposed.

Objectives: In the general population, cadmium seems to be responsible for hypertension, atherosclerosis and an increase in acute coronary events. Therefore, the purpose of this meta-analysis was to analyze controlled studies conducted on cadmium and arterial pressure in occupationally-exposed workers. Materials and Methods: After analyzing all the relevant articles found in the literature, 6 publications were selected. Results: A higher prevalence of hypertension and higher values of systolic and diastolic blood pressure were recorded in the exposed subjects. Conclusions: Cadmium in occupationallyexposed individuals appears to induce an increase in systolic and diastolic blood pressure and an increase in the prevalence of hypertension.

The literature suggests that farmers nowadays are more likely to contract cardiovascular diseases than in the past. This study involved 79 farmers and 64 controls. The workers completed a questionnaire to identify exclusion factors for audiological and cardiovascular risk factors. The participants underwent medical examination, measurement of blood pressure, electrocardiogram, blood tests, audiometry, and measurement of noise exposure. The farmers were found to have a higher prevalence of systolic and diastolic arterial hypertension as well as electrocardiogram (ECG) abnormalities compared with the controls. A significant prevalence of arterial hypertension was detected in the farmers exposed to noise, when compared with those who were not exposed. These results suggest that farmers are at risk of cardiovascular effects and that noise is a cardiovascular risk factor for farmers
