The investigated subjects numbered 36 and ranged in age from 22 to 55 years (average, 36 +/- 1.9 years). The jobs represented included mainly: diggers, bulldozers, driver, drillers, blasters, road-service workers, electric and mechanic fitters. Endpoints measured and evaluated included: arterial blood pressure, pulse rate, biometric characteristics (age, occupational experience, body height and weight), common risk factors, such as family antecedents, cigarette smoking, alcohol consumption, level of physical activity at and off work, etc. For this sample of open-pit workers, findings indicated a relatively high incidence of hypertension (28% of subjects). The level of arterial hypertension consistently correlated with worker age, length of occupational experience, and body weight. There was high prevalence of cardiovascular risk factors: alcohol consumption, family history, cigarette smoking, use of salty foods, overweight. The observed changes in the cardiovascular system and high prevalence of risk factors point to the necessity of taking specific medical prevention measures. These have been taken into consideration in designing the overall program of upgrading work conditions and organization, as well as improving the style of life of \"Asarel\" MMW workers.","PeriodicalId":20520,"journal":{"name":"Problemi na khigienata","volume":"20 ","pages":"47-59"},"PeriodicalIF":0.0,"publicationDate":"1995-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19506128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analysis of activities showed physical effort (dynamic and static) to be the major problem at the open pit, though varying in extent between jobs (most prominent for blasters and bulldozerists). Nervous/emotional strain, while not leading, was sustained mostly by diggers and blasters, followed by drivers. Organization of work (shift regimen, no regulated breaks, stepwise schedule of days off work) was hardly appropriate and did not allow for recovery. Interviewed workers qualified working conditions as extremely unfavorable; they disapproved with the physical factors of the occupational environment, the workplace, the state of machines and devices, and remuneration for work performed. Exertion from work, assessed by pulse rate and energy expended, was moderate for most activities of diggers, drivers, and drillers. The burden of physical effort was great for blasters at the open pit and for diggers and drillers performing extra repair operations (pulse rate, 100-110 strokes/min; energy expended, 5.2-5.5 Kcal/min). Hardest and least attractive was the work of blasters at stores for explosive materials (pulse rate, 120-141 strokes/min; energy expended, 5.5-6.5 Kcal/min). These adverse factors of labor activities might produce a negative impact on worker health and performance, leading to occupational impairment of their musculoskeletal system, to labor-related disorders of their cardiovascular and nervous systems, etc. Preventive measures are thus necessary to limit physical exertion, optimize the work-and-rest regimen; also, there is a need for conducting pertinent preventive medical examinations, providing social measures (conditions for transportation, rest, nutrition, sports), etc.","PeriodicalId":20520,"journal":{"name":"Problemi na khigienata","volume":"20 ","pages":"35-47"},"PeriodicalIF":0.0,"publicationDate":"1995-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19506127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Where systematic and ubiquitous excesses over admissible noise level occur in an urban environment, a special case of health impact is that produced upon an inpatient's course of recovery from illness. This paper presents evidence from a survey of mean excesses over HEI-regulated noise standards for zones enclosing 16 Sofia inpatient facilities. The procedure used to determine and map mean excesses in cities has been made available to the preventive network of local HEIs countrywide; however, it still has not been put into practice everywhere. This renewed presentation, it is hoped, should contribute to recognizing its necessity and making use of the technique. The most frequently encountered excesses over the admissible noise level were within the range 15-20 dB A. For districts incorporating hospital institutions, this acoustic situation may be qualified as not only inadequate to requirements but also as generating a health risk for vulnerable population groups. Clearly, the noise regimen observed in the surveyed zones in an environmental physical hazard hindering the process of recovery from illness--with all health, social, and economic negative effects entailed.","PeriodicalId":20520,"journal":{"name":"Problemi na khigienata","volume":"20 ","pages":"17-22"},"PeriodicalIF":0.0,"publicationDate":"1995-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19504966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
