IN THIS WORK, A NEW, SIMPLE AND SENSITIVE METHOD FOR PRE-CONCENTRATION OF ULTRA TRACE MERCURY IN AIR, RIVER AND DRINKING WATER SAMPLES WAS DEVELOPED PRIOR TO DETERMINE BY COLD VAPOR ATOMIC ABSORPTION SPECTROMETRY (CV-AAS). PILOT MULTIWALL CARBON NANOTUBES TRAP / COLD VAPOR ATOMIC ABSORPTION SPECTROMETRY (PCNT-CVAAS) WAS DESIGNED...

THE WORLDWIDE DRAMATIC INCREASE IN MOBILE PHONE USE HAS GENERATED GREAT CONCERNS ABOUT THE DETRIMENTAL EFFECTS OF MICROWAVE RADIATIONS EMITTED BY THESE COMMUNICATION DEVICES.REACTION TIME PLAYS A CRITICAL ROLE IN PERFORMING TASKS NECESSARY TO AVOID HAZARDS. AS FAR AS WE KNOW, THIS STUDY IS THE FIRST SURVEY THAT REPORTS DECREASED REACTION TIME AFTER EXPOSURE TO ELECTROMAGNETIC FIELDS GENERATED BY A HIGH SPECIFIC ABSORPTION RATE MOBILE PHONE...

INTRODUCTION: INDUSTRIAL PROGRESS AND INCREASING EVERYDAY NEEDS TO THE MORE OUTPUT NECESSITATING THAT WORKING IN CLOSED AREA DURING DAY AND NIGHT SHOULD BE CONTINUED, AND IN THIS CASE BY USING OF ARTIFICIAL BRIGHTNESS SOURCES IT HAS SEPECIAL EFFECTS BECAUSE THE LACK OF IT IN AN OFFICE ENVIRONMENT ALSO CAUSE NERVE FATIGUE AND OTHER HAZARDS TO THE HEALTH AND VISION OF EMPLOYERS.ONE OF THE INFORMATION SYSTEMS THAT THE USE OF IT PREVALENT RECENTLY IS GIS OR LOCATION DATA SYSTEM...

OBJECTIVE: WELDING FUMES CONSIST OF A WIDE RANGE OF COMPLEX METAL COMPONENT. METAL IONS INDUCED LUNG DISEASES SUCH AS CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD), BRONCHITIS, METAL FUME FEVER, CANCER AND FUNCTIONAL CHANGES IN THE LUNG. SINCE OXIDATIVE STRESS PLAYS A ROLE IN THIS PATHOGENESIS, IT IS CHARACTERIZED BY AIRFLOW LIMITATION. THIS STUDY FOCUSED ON THE ANTICIPATION OF THE OXIDATIVE STRESS BIOMARKER BY THE AMOUNT OF URINARY METALS AND SPIROMETRY AIRFLOW INDEX...

LIGHTING IS ONE OF THE PHYSICAL FACTORS OF THE WORK ENVIRONMENT ANDONE ACTION OF CLARIFICATIONON SURFACES OF OBJECTS AND RECOGNIZE THEM FOR MAKING VISIBLE. GOOD LIGHTING CAN IMPROVE GENERAL WORKING CONDITIONS. AS A FACTOR IN PHYSICAL HEALTH AND SAFETY OF WORKERS TO MEET NORMAL OPERATING CONDITIONS AND IMPLEMENT BEST PRACTICE IS NECESSARY. IF NOT DONE CAREFULLY IN DESIGNING A LIGHTING SYSTEM FOR THE EFFECTS OF EYESTRAIN, HEADACHES, IMPAIRED VISION, STROKE (BOLDNESS) AND WORK-RELATED ACCIDENTS ARE...

THE PURPOSE OF THIS STUDY WAS TO INVESTIGATE THE EFFECTS OF PHYSICAL AND PERSONAL RISK FACTORS ON SICK LEAVE DUE TO MUSCULOSKELETAL DISORDERS IN AN IRANIAN CAR MANUFACTURING COMPANY.THIS CROSS-SECTIONAL STUDY WAS CONDUCTED AT ASSEMBLY PLANT OF A CAR COMPANY.234 WORKERS WERE RANDOMLY SELECTED WHO HAD SICK LEAVE DUE TO MUSCULOSKELETAL DISORDERS DURING LAST YEAR. PHYSICAL ERGONOMICS RISK FACTORS CHECKLIST AND PERSONAL INFORMATION QUESTIONNAIRE WERE USED AS DATA GATHERING TOOLS...

THE STUDY INVESTIGATED THE EFFECTS OF THE TWO NEW DESIGNS OF COTTON GLOVES ON SEVERAL HAND PERFORMANCE CAPABILITIES (INCLUDING TIME TO COMPLETE THE PEGBOARD TEST, NUMBER OF ERRORS, HAND GRIP STRENGTH, PINCH STRENGTH AND FOREARM TORQUE STRENGTH) AND COMPARED THEM AGAINST THE BAREHANDED, SINGLE-LAYERED AND DOUBLE COTTON GLOVE CONDITIONS WHILE WORKING WITH HAND TOOLS (SCREWDRIVERS AND PLIERS)...

THIS STUDY WAS CARRIED OUT OVER AN EDUCATIONAL YEAR IN 6 PRIMARY SCHOOLS TO DETERMINE INDOOR CLASSROOM PARTICULATE MATTER (PM1, PM2.5 AND PM10) AND OUTDOOR PM2.5 CONCENTRATIONS AND TO IDENTIFY THE MAIN DETERMINANTS OF INDOOR CLASSROOM PM2.5CONCENTRATIONS...

INTRODUCTION: DUE TO INCREASING DEMAND OF HEALTHCARE SYSTEMS AND NURSING SHORTAGE, FINDING FACTORS THAT PREDICT NURSES' JOB SATISFACTION ARE VERY IMPORTANT. THIS STUDY WAS CONDUCTED TO DETERMINE JOB SATISFACTION OF NURSES AND ITS CONTRIBUTING FACTORS...

THE AIM OF THIS STUDY WAS TO EVALUATE THE ILLUMINATION LEVELS, TO EXAMINE THE EFFECT OF LIGHTING CONDITIONS (INCLUDING LIGHTING CHARACTERISTICS AND LIGHTING DISTURBANCES) ON EMPLOYEE SATISFACTION, JOB PERFORMANCE, SAFETY AND HEALTH, AND TO COMPARE THE EMPLOYEES' PERCEPTION OF LIGHTING LEVEL WITH ACTUAL ILLUMINANCE LEVELS IN A HOSPITAL SETTING...

INTRODUCTION: STUDIES IN RECENT YEARS HAVE SUGGESTED THAT HEALTH BELIEFS, MENTAL HEALTH AND SOMATISING TENDENCY CAN AFFECT MUSCULOSKELETAL DISORDERS (MSDS).THE PRESENT SURVEY WAS CONDUCTED TO DETERMINE THE PREVALENCE OF MSDS AMONG IRANIAN OIL FIELD WORKERS AND THEIR ASSOCIATION WITH THESE PSYCHOLOGICAL AND PHYSICAL RISK...

DATA ON THE PHYSICAL STRENGTH CAPABILITIES OF USERS ARE ESSENTIAL FOR DESIGNING THE SAFE AND USABLE PRODUCTS. THE PURPOSE OF THIS STUDY WAS TO DETERMINE PEAK LATERAL PINCH STRENGTH, KEY PINCH STRENGTH AND TIP-TO-TIP PINCH STRENGTH AMONG 328 (104 MALES, 224 FEMALES) PARTICIPANTS AGED BETWEEN 7 AND 30 YEARS IN TABRIZ...

INTRODUCTION: CONSTRUCTION IS ONE OF THE MOST IMPORTANT INDUSTRIES IN WHICH MANY WORKERS START ON ACTIVITY. WORKERS WHO EMPLOYEE IN THIS INDUSTRY ARE VICTIMS OF MANY OCCUPATIONAL ACCIDENTS ACCIDENT AND INJURIES. THERE ARE A FEW STUDIES ON EFFECTIVE FACTORS AND PATTERNS ON CONSTRUCTION ACCIDENTS IN MANY CITIES OF THE COUNTRY. THEREFORE, THE PURPOSE OF THE PRESENT STUDY IS OF FOCUSED ON DETERMINING THE FREQUENCY AND UNDERLYING REASONS IN CONSTRUCTION ACCIDENTS...

THIS STUDY WAS CONDUCTED TO EXPLORE THE POTENTIAL ASSOCIATIONS BETWEEN MERCURY BLOOD LEVELS AND THE NEUROPSYCHOLOGICAL FUNCTION. MERCURY GET DISTINGUISHED FROM OTHER TOXIC POLLUTANTS, DUE TO THEIR NON-BIODEGRADABILITY CAN ACCUMULATE IN LIVING TISSUES OF HUMAN BODY...

BACKGROUND: MANUAL MATERIAL HANDLING (MMH) TASKS CAN BE FOUND IN MOST WORKPLACE WHICH COULD BE A RISK FACTOR FOR WORK-RELATED MUSCULOSKELETAL DISORDERS (WMSDS).THIS STUDY WAS CONDUCTED TO DETERMINE THE PREVALENCE OF MSDS AND ASSESS THE ACCEPTABLE WEIGHTS AMONG IRANIAN CASTING WORKERS...

OBJECTIVE: THE EVIDENCE DEMONSTRATES THAT OXIDATIVE STRESS IS THE MAIN CAUSE FOR HEXAVALANT CHROMIUM-INDUCED DAMAGE. IN THIS STUDY, OXIDATIVE STRESS AS A TOXICITY OF HEXAVALENT CHROMIUM IN CHROME ELECTROPLATING WORKERS WAS INVESTIGATED USING THE MULTIVARIATE MODELING APPROACH. THE MAIN GOAL OF THIS ANALYSIS IS THE POSSIBILITY OF CATEGORIZING THE CHROME ELECTROPLATING WORKERS BASED ON OXIDATIVE STRESS PARAMETERS AS PREDICTOR VARIABLES...

INTRODUCTION: EMERGENCY MEDICAL SERVICES ARE ONE OF THE MOST PHYSICAL AND PSYCHOLOGICAL STRESSFUL WORK. PHYSICAL CONDITIONS AND APPROPRIATE SIZE OF BODY ARE IMPORTANT IN THIS JOB. BODY SIZE SHOULD BE SO THAT THE PERSON CAN DO HIM ACTIVITIES EASILY SUCH AS CARRYING PATIENT AND DRIVE AMBULANCE. THERE ARE NO RECOMMENDED VALUES OR RANGE ABOUT THE APPROPRIATE BODY SIZES OF EMERGENCY MEDICAL SERVICES WORKERS. THESE VALUES ARE NECESSARY FOR OPTIMUM PERFORMANCE.ANTHROPOMETRIC MEASUREMENT CAN BE USED FOR PROVIDING SUITABLE RANGE TO STAFF SELECTION. THE AIM OF THIS STUDY WAS FOR IDENTIFYING APPROPRIATE ANTHROPOMETRIC DIMENSIONS FOR SELECTING OF A PERSON FOR EMERGENCY MEDICAL SERVICES...

FOR INVESTIGATING TOXIC EFFECT OF ARSENIC (AS) AND MERCURY (HG) IN HEALTH AND SAFETY OF PETROCHEMICAL WORKERS, A METHOD BASED ON DISPERSIVE IONIC LIQUID-LIQUID MICROEXTRACTION (DILLME) PROCEDURE FOR PRE-CONCENTRATION OF HG AND AS HAS BEEN DEVELOPED PRIOR TO DETERMINE BY COLD VAPOR/HYDRIDE GENERATION ATOMIC ABSORPTION SPECTROMETRY (CV/HG-AAS)...
