摘要

冰岛铝冶炼厂进行的环境监测包括对羊和马下颌骨进行氟化物分析。对2007年至2019年对羊和马的氟化物分析进行了回顾性统计建模。研究人员还调查了骨组织中氟化物浓度与动物的年龄和地区来源之间的关系，以及靠近铝冶炼厂的影响。此外，还对绵羊下颌骨氟积累的年际发展及病理变化进行了探讨。年龄与氟浓度呈正相关，超过一定年龄后氟浓度下降。在有铝冶炼厂的地区、冰岛西南部和东部的羊以及西南部的马的体内，氟化物浓度最高。2007-2014年，西南某冶炼厂周边羔羊体内氟化物浓度显著下降。在冶炼厂周围的羊的牙釉质中发现了与氟中毒相一致的病理变化，这与2006年8月的一次意外排放爆发有关。关键词:家畜，环境监测，氟中毒，食草动物，冰岛，病理学

Accumulation of fluoride in Icelandic sheep and horses 2007-2019 and the effect of proximity to aluminium smelters

Environmental monitoring by aluminium smelters in Iceland has included fluoride analysis of sheep and horse mandibles. Statistical modelling was done retrospectively on fluoride analyses of sheep and horses from 2007 to 2019. Relationships between the fluoride concentration in bone tissue and the age and the regional origin of the animals were investigated, along with the effect of proximity to aluminium smelters. Furthermore, the development of fluoride accumulation in sheep mandibles through the years and pathological changes were explored. A positive correlation was found between age and fluoride concentration, with a decline after a certain age. Fluoride concentration was highest in areas with aluminium smelters, in sheep in the Southwest and East of Iceland and in horses in the Southwest. Fluoride concentration in lambs around a Southwest smelter decreased significantly during 2007-2014. Pathological changes compatible with fluorosis were seen in the tooth enamel of sheep from around the smelter, in connection with an accidental burst of emissions in August 2006. Keywords: Domestic animals, environmental monitoring, fluorosis, herbivores, Iceland, pathology

期刊介绍： Icelandic Agricultural Sciences is published annually, or more frequently. The deadline for submitting manuscripts that are intended to appear within that year is September. The journal is in English and is refereed and distributed internationally. It publishes original articles and reviews written by researchers throughout the world on any aspect of applied life sciences that are relevant under boreal, alpine, arctic or subarctic conditions. Relevant subjects include e.g. any kind of environmental research, farming, breeding and diseases of plants and animals, hunting and fisheries, food science, forestry, soil conservation, ecology of managed and natural ecosystems, geothermal ecology, etc.
