Health disorders of the employees exposed to organic solvents at work The aim of the study was to investigate the impact of exposure of organic solvents at work on related health disorders in Latvia. Two surveys were carried out with a total number of 2520 respondents. Retrospective analysis of incidence of occupational diseases caused by organic solvents was performed. 21.4% of employees indicated absorption of chemical substances through skin. The incidence of occupational diseases caused by organic solvents has a stable trend to decrease from year 2003. 58.8% of employees believe that their long-term health disorders are related to their work environment or work conditions. While organic solvents remain an essential working risk problem in Latvia, the data on exposed persons and their health disorders caused by organic solvents are not sufficient enough. Biological monitoring could facilitate early diagnostics of non-specific health disorders caused by organic solvents.
Investigation of occupational morbidity in wood processing industry in comparison with other manufacturing industries and with occupational morbidity in Latvia at large The aim of the study was to investigate occupational morbidity in the wood processing industry to gain understanding of the real situation of occupational health and to improve the diagnostics of occupational diseases. The occupational morbidity in Latvia has gradually increased from 1993 to 2004, with a slight decrease in 2005 and 2006 followed by an increase in 2007. In the year 2004, the number of first-time occupational diseases patients exceeded the number of occupational diseases patients registered in the year 1993 by 9.5, but the number of registered first-time incidences of occupational diseases in comparison with 1993 had increased by 14.5 times. In the manufacturing industry, wood and cork production, a trend of increasing rate of occupational diseases can also be observed in Latvia. A particularly rapid increase was observed in specific illnesses related to the musculoskeletal and connective tissue system, carpal tunnel syndrome as well as to occupational hearing loss, which might be explained by changes in the occupational risk factors. Despite an increase in the total number of occupational diseases in the industry of wood and cork products over the whole study period, these industries have lower levels of occupational diseases in comparison with occupational morbidity in such fields as health and social care, the extraction industry and quarry management, transportation and transport services, communications and telecommunications. In developed European Union countries, over the last few years, the number of occupational diseases has decreased, while there has been an increasing trend in Latvia. This can be explained by the fact that the working conditions in the European Union have been improving over the last few decades, and correspondingly the number of occupational diseases is decreasing. However, in Latvia, the diagnostics of the occupational diseases is rapidly improving, while improvement of working conditions has started relatively recently. Furthermore, the process has not been rapid, and therefore, results could be expected only in the future.
Abstract The paper summarises the main findings on Chernobyl Nuclear Power Plant (CNPP) accident recovery workers from Latvia and their health disturbances, which have been studied by the authors during the last two decades. Approximately 6000 persons from Latvia participated in CNPP clean-up works in 1986–1991. During their work period in Chernobyl they were exposed to external as well as to internal irradiation, but since their return to Latvia they were living in a relatively uncontaminated area. Regular careful medical examinations and clinical studies of CNPP clean-up workers have been conducted during the 25 years after disaster, gathering knowledge on radiation late effects. The aim of the present review is to summarise the most important information about Latvian CNPP clean-up worker health revealed by thorough follow-up and research conducted in the period of 25 years after the accident. This paper reviews data of the Latvian State Register of Persons Exposed to Radiation due to CNPP Accident and gives insight in main health effects found by the researchers from the Centre of Occupational and Radiological Medicine (Pauls Stradiņš Clinical University Hospital) and Rīga Stradiņš University in a number of epidemiological, clinical, biochemical, immunological, and physiological studies. Latvian research data on health condition of CNPP clean-up workers in the late period after disaster indicate that ionising radiation might cause premature ageing and severe polymorbidity in humans.
