Objective: The purpose of the study is to evaluate whether low-dose exposure to benzene, an environmental pollutant to which male and female traffic policemen are daily exposed to could cause alterations in plasma luteinizing hormone (LH) levels.
Methods: From an initial sample of 1594 workers, we only selected 95 workers of whom study we knew the values of late-shift benzene and LH hormone. All subjects underwent biological monitoring (final blood benzene evaluation) and luteinizing hormone dosing.
Introduction: The aim of our study is to compare liver damage in "outdoor" environment technicians, a category occupationally exposed, and in "indoor" workers.
Materials And Methods: We studied 142 male technicians of the environment exposed to urban pollution and 142 male "indoor" workers not exposed. We compared mean and standard deviation of the following liver parameters: glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), gamma-glutamyl-traspeptidasi (γGT) and alkaline phosphatase (PHA), total bilirubin (TB) and direct (DB).
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.
Objectives: Everyday outdoor workers are exposed to chemicals including the polycyclic aromatic hydrocarbons (PAHs). The aim of the study is to evaluate the relationship between hydroxypyrene and blood pressure in outdoor workers.
Materials And Methods: 374 subjects of both sexes entered the study.
Nickel (Ni) and Ni compounds are widely present in the urban air. The purpose of this study is to estimate exposure of individuals to Ni and the correlation between this exposure and the values of blood counts in outdoor workers. This study focused on a sample of 101 outdoor workers (55 male and 46 female; 65 nonsmokers and 36 smokers), all employed in the municipal police in a large Italian city.

This study focuses on the analysis of the hepatic effects induced by the use of some organic solvents employed in the printing industry.
Methods: We studied a group of 194 workers: 93 exposed and 101 not exposed.
Background: Polycyclic aromatic hydrocarbons (PAHs) are widely present in the air pollution. The urinary hydroxypyrene (1-HOPu) is considered the main biological biomarker currently available to measure the exposure to PAH. It is supposed responsible of an increase of estradiol levels in males.

Methods: 359 male subjects were included in the study and divided on the basis of job, age, length of service and smoking habits. The dosage of the atmospheric Ni was performed by personal dosimetries on a sample of the workers included in the study.
Background: The aim of this study was to evaluate whether urban pollutants can affect plasma levels of antidiuretic hormone (ADH) in outdoor workers.
Materials And Methods: We selected 208 subjects, 104 exposed to urban stressors and 104 non exposed to urban stressors. We divided these workers in 3 groups: Group 1 (non-smokers and non-drinkers), Group 2 (smokers and not drinkers) and Group 3 (drinkers and not smokers).
Background: The occupational exposure to urban pollution may induce adverse effects on the human health.
Methods: Plasma levels of thyrotropin stimulating hormone (TSH), free thyroxine (FT4) and free triiodothyronine (FT3) of 50 outdoor workers and 50 indoor workers were compared.
Results: In the outdoor workers the TSH levels were significantly higher than in the control subjects (p =0.
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.
Introduction: In health care the contact with body fluids, such as saliva or blood is frequent. The aim of our study was to analyze whether the exposure to biological risks in health care, in particular exposure to HBV and HCV, could cause alterations of some liver parameters.
Materials And Methods: Our study analyzes of 254 health care workers of a big hospital in Rome.
Objectives: The aim of this study is to estimate the exposure to Cd in a group of roadmen compared to a group of drivers by environmental monitoring and biological monitoring of blood and urinary Cd. It aims to evaluate whether exposure to Cd can affect plasma cortisol.
Materials And Methods: The initial sample was composed by 130 employees of Municipal Police Force (roadmen and drivers).
Objectives: Otoacoustic emissions are signals that originate from the cochlea, measuring them can be considered an objective method in the assessment of auditory function. In our study we wanted to examine their efficiency among normal audiological exams.
Materials And Methods: We examined 14 workers exposed to continuous aircraft noise.
The aim of this study is to estimate whether the occupational exposure to low dose anesthetic gases could cause alterations of blood parameters in health care workers. 119 exposed subjects and 184 not exposed controls were included in the study. Each worker underwent the complete blood count test (CBC), proteinaemia, leukocyte count, serum lipids, liver and kidney blood markers.

Methods: The study included 48 exposed workers and 86 unexposed controls. All workers included in the study underwent blood count, white blood count, total, direct and indirect bilirubin, transaminases, alkaline phosphatase and cholinesterase.
Background: The occupational exposure to urban pollution may induce adverse effects on the cardiovascular system.
Methods: Basal blood pressure, electrocardiogram (ECG) and the dynamic blood pressure monitoring during the work shift of 16 policemen (outdoors workers) and 16 administrative employees (indoor workers) were compared.
Results: The mean value of all the diastolic blood pressure surveys in policemen (84,53 ± 10,78) is significantly higher (p = 0,014) than the mean value of all the diastolic blood pressure surveys in indoor workers (82,74 ± 11.

Acrylonitrile is an intermediary with possible adverse health effects in the synthesis of organic products, such as acrylic fibres. This investigation was undertaken to determine the possible changes in the peripheral blood counts in workers of a polyacrylic fibres plant. The study involved 218 workers exposed to acrylonitrile at low doses and a control group of 200 unexposed workers.
