To investigate the temporal trend in exposure to certain heavy metals among the inhabitants of north-eastern Finland, a pilot study was carried out involving serum and hair samples from group of 11 persons monitored in Ivalo in 1982 and 1991. A further 6 persons residing near the Russian border in Nellim and 10 adults and 2 children residing in the Sevettijärvi-Näätämö area also participated in 1991. In addition, serum and hair samples were also obtained from controls residing in the Helsinki area. Total mercury content, determined by flow injection analysis and the amalgam system, pointed to a decrease in concentrations in the hair of inhabitants of Ivalo, whereas mercury concentrations were found to be higher in those residing near the Russian border. The mercury concentrations in the hair of northern inhabitants were about 4 times greater than those in the hair of the people from southern Finland on average. No trend towards an increase or decrease was found in copper and zinc concentrations in hair and serum as determined by atomic absorption spectrometry in employing the flame technique. Selenium has been thought to act as an antagonist to the heavy metal mercury. The addition of selenium to fertilisers began in Finland in 1984, but such fertilisers have not been used widely in Lapland. Selenium concentrations, determined by flameless atomic absorption spectrometry, showed an increase with time in the inhabitants of northern Finland. Selenium concentrations were higher in the residents of Lapland than in the southern Finns, but this difference occurred after the addition of selenium to fertilisers has begun to be less common.</p>","PeriodicalId":77012,"journal":{"name":"Arctic medical research","volume":"55 2","pages":"83-91"},"PeriodicalIF":0.0,"publicationDate":"1996-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19728098","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}

Training consisted of approximately 12 h/d of moderately intense activity. Variables examined included body composition, TBW, and various blood and urinary parameters indicative of hydration. Dietary food and fluid records were also maintained. Body composition changes were consistently with the high energy expenditure and insufficient energy intake. Despite a decrease in TBW, significant dehydration as assessed by blood and urinary parameters did not occur over the 8d period, therefore no relationships were found between TBW and any of the clinical indicators of dehydration. The change in TBW was reflective of a decrease in lean body mass. These data suggest that during cold-weather military field exercise, despite high activity levels and a negative energy balance, body fluid balance can be maintained when particular attention is paid to fluid intake.</p>","PeriodicalId":77012,"journal":{"name":"Arctic medical research","volume":"55 1","pages":"20-6"},"PeriodicalIF":0.0,"publicationDate":"1996-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19864892","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}

In the 1970s the preventive effect of marine fat on cardiovascular disease, thrombosis and atherosclerosis was described. The low incidence of ischemic heart disease among Greenlanders has been related to the high intake of marine food. Since 1990 routine autopsies have taken place in two towns in Greenland, Nuuk and Ilulissat. The autopsies represent 26% of the total number of deaths in these two towns. Samples have been collected from 104 autopsies. International cooperative studies have analysed specimens in relation to ischemic heart disease as a benefit related to diet, as well as the level of heavy metals and organochlorine in organs as a risk related to diet. High amounts of mono-unsaturated and Omega-3 poly-unsaturated fatty acid were found in adipose tissue. Liver analyses of selenium have confirmed the expected high intake among Greenlanders. Reduced atherosclerotic lesions were found in the coronary arteries. Blood pressure levels calculated from renovascholopathia of hypertension indicate prevailing levels similar to those in industrialized countries. Some factors in Greenland may be protecting the coronary arteries, thereby of setting the expected effect of hypertension. The level of methyl mercury in organs is generally high.
