Echocardiography involves strenuous postures of the upper limbs. This study explored the physical workload in the neck and upper limbs in sonographers performing echocardiography, and the extent to which the workload differs from than in other work tasks (other sonographic examinations, and nonsonographic tasks).
The number of older workers is increasing throughout the industrialised world and older workers are known to be more frequent in the injury-prone agricultural sector. This paper sought to extend knowledge by reviewing evaluated intervention studies intended to decrease risks and work injuries among older workers in agriculture.
Occupational exposure to diesel exhaust is common due the widespread use of diesel-powered combustion engines. Diesel exhaust is chemically complex and consists of thousands of compounds present as gases and particulate matter. Both nitrogen dioxide (NO2) and elemental carbon (EC) have been used as markers for diesel exhaust exposure. Currently EC is regarded as the best surrogate of diesel exhaust. The objective was to quantify the occupational exposure to diesel exhaust in underground tunnel construction work using a multi-metric approach, and to investigate the correlations between NO2, respirable EC, respirable organic carbon (OC), respirable total carbon (TC), respirable dust (RD), and particle number. Also, the use of NO2 as a proxy for diesel exhaust was evaluated, how much of the variability in the diesel exhaust exposure was attributed to within and between individual factors and if there was a difference between expert and self-administered measurements of NO2.
More people will probably continue working into old age in the future due to the increased size of aging populations in many countries. We therefore need to know more about older workers' health in relation to their work situation and retirement. This study is a part of a theoretical development of older workers' situations. Older workers' situations are theoretically themed in nine areas by the authors of this study (http://www.swage.org/ ).
Pregnant women living in areas with polluted air have children who weigh slightly less at birth. Although the impact is very small, the connection is clear, a researcher at Lund University, Sweden has demonstrated. “This is despite the fact that air pollution in Skåne (where the study was conducted) is usually within approved EU limits. Even low levels of pollution that are considered acceptable could have an effect”, says Ebba Malmqvist
