Can noise cause high blood pressure? Occupational risk in paper industry.

Objectives: The authors hypothesize cardiovascular effects in paper industry workers exposed to noise.

Materials And Methods: The study included 72 paper industry workers exposed to noise and two control groups not exposed to noise. The workers completed a questionnaire and underwent a medical examination, measurement of blood pressure, electrocardiogram, blood tests, audiometry and measurement of noise exposure.

Liver damage in automotive and industrial workers of the glass.

Objective: High doses of organic solvents can cause hepatic disease. We investigated whether exposure to low doses of solvents in automotive and industrial workers may lead to changes in liver tests.

Methods: We studied the liver parameters (glutamic oxaloacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), gamma-glutamyl-traspeptidasi (γ-GT), alkaline phosphatase (PHA), total (TB) and direct bilirubin (DB) of 24 workers exposed to organic solvents and of 30 unexposed controls.

Relationship between occupational exposure to cadmium, transaminases and γ-GT in workers exposed to urban stressors.

Background: The exposure to Cd has been linked to many disease and liver is the major target organ of Cd toxicity following acute or chronic exposure.No study has ever evaluated the association between liver function tests and exposure to Cd present in urban air in outdoor workers.

Materials And Methods: In order to assess the relationship between the exposure to urban Cd and the associated changes in liver functionality markers, we conducted a study on 110 municipal policemen divided into 2 groups according to their tasks: 60 traffic policemen and 50 drivers, underwent tests for the determination of the urinary values of Cd correlated with the blood levels of transaminases and ?-GT.
