selenosis
相关语句
  硒中毒
    Yutangba, Enshi, Hubei province, China is the only site in the world where a sudden incidence of human selenosis took place, and one of the typical Se-rich areas in China.
    湖北恩施渔塘坝是中国唯一发生过人群硒中毒爆发性流行的地区,也是中国较为典型的高硒地区之一。
短句来源
    As a result,it is concluded that livestock poisoning,which happened in Suzhou,Northwest China,recorded by Marco Polo in 〈The Travels of Marco Polo〉 might not be selenosis,but the poisoning caused by toxic alkaloid components(Swainsonine) in Oxytropis.
    由此推断,引起《马可波罗游记》中记载的中国西部肃州牲畜毒草中毒并非硒中毒,中毒的原因是棘豆植物中的生物碱成分苦马豆素(Swainsonine)。

  selenosis
It is proposed that this selenosis area coincides with Mo, F and V toxicity based on their higher concentrations in rocks, soils and plants.
      
The revegetated soil derived from bone coal and V-Mo ore dumps with excess Se, Mo, V and F concentrations in this ecosystem might have been essentially responsible for selenosis incidence of Shuang'an site in Ziyang County, Shaanxi Province.
      
In order to investigate the relationships between Se and other mineral elements and selenosis, bone coals, V-Mo ores, rocks, soils and plants were sampled from each site.
      
The Shuang'an site is the most serious selenosis site in Ziyang County, Shaanxi Province, which was the second selenosis site in China.
      
Some selenium values were high enough to suggest the possibility of selenosis in sheep.

Yutangba, where a sudden incidence of human selenosis occurred in 1963, is located in the northern part of Shuanghe community about 81 km SE of Enshi City, Hubei Province, China. In Yutangba, native Se extensively exists within Se-rich carbonaceous rocks, abandoned stone coal spoils and high-Se soils close to Se-rich carbonaceous strata. The distribution of native Se is parallel with Se-rich carbonaceous strata, with local circles or strips. Selenium particles become sparse from the Permian Maokou to Wujiaping...

Yutangba, where a sudden incidence of human selenosis occurred in 1963, is located in the northern part of Shuanghe community about 81 km SE of Enshi City, Hubei Province, China. In Yutangba, native Se extensively exists within Se-rich carbonaceous rocks, abandoned stone coal spoils and high-Se soils close to Se-rich carbonaceous strata. The distribution of native Se is parallel with Se-rich carbonaceous strata, with local circles or strips. Selenium particles become sparse from the Permian Maokou to Wujiaping formation along the dip. Native Se is probably the main dominance, and once formed, will be re-deposited in special sites such as near water table. However, when Se-rich stone coal removed from deep as a fuel or fertilizer, a large amount of native Se will be quickly oxidized again and transformed to soluble Se, which will be enriched in local food via water irrigation systems. So, Se-rich carbonaceous strata are a necessary condition for the incidence of Selenosis, and human cultivating manner and activities such as mining stone coal as a fuel or fertilizer will provide a sufficient condition for oxidation of elemental Se and its transportation. When soluble Se is accumulated to a certain extent and is under the suitable environmental condition, selenosis would occur again in some places of Enshi Prefecture.

自然硒在渔塘坝富硒碳质岩层及其附近的土壤、废弃“石煤”堆中广泛发育。渔塘坝自然硒的空间分布与富硒碳质岩层密切相关,其纵向分布整体与富硒碳质岩层的走向一致,局部地段呈片状或环带状;横向上沿着富硒碳质岩层的倾向方向,从二叠纪茅口组的碳质硅质岩层到吴家坪组的碳质页岩层,自然硒的发现由易到难。渔塘坝当前的地质环境有利于自然硒的形成和保存,且一旦在表生环境形成后将会在特殊的地段发生次生富集。但是,自然硒形成的地质环境一旦被人类活动打破,暴露于地表的自然硒也能够发生迅速的氧化而再次迁移,进入河流和当地居民的食物链系统。因此,渔塘坝及恩施地区广泛分布的富硒碳质岩层为硒中毒的发生提供了必要条件, 当荒地开垦或开挖“石煤”等人类活动为自然硒的氧化和迁移提供充分条件时,硒中毒的发生仍将不可避免。

Such a viewpoint has always been prevailing in selenium academic field for many years that the livestock poisoning due to having eaten poisonous grass is referred to as selenosis,which happened in Suzhou of Northwest China,recorded in 〈The Travel of Marco Polo〉 during the 13~(th) century.However,even up to now,there has not been sufficient scientific evidence suggesting that the livestock poisoning is indeed a case of selenosis.In order to clarify the historic problem of whether livestock poisoning recorded by Marco Polo in 1295,is selenosis or not,the present study surveyed endemic livestock poisoning which has been prevailing in the Hexi Corridor in recent years,and the environmental geochemistry background of Se in Sunan County,the Hexi Corridor,which belongs to a part of Suzhou in ancient China.The results of investigation indicate:(1) the toxic grass which had caused Marco Polo's horses to be poisoned could be Oxytropic;(2) the average Se content in soils where Oxytropic grew is close to the mean value of the world soil;(3) Se level in Oxytropis is much lower than the threshold of 3.0 mg/kg to cause most farm animals to bepoisoned.As a result,it is concluded that livestock poisoning,which happened in Suzhou,Northwest China,recorded by Marco Polo in 〈The Travels of Marco Polo〉 might not be selenosis,but the poisoning caused by toxic alkaloid components(Swainsonine) in Oxytropis.

硒学术界普遍认为《马可波罗游记》中记载的中国西部牲畜毒草中毒是人类历史上最早对“硒中毒”的描述,但至今没有可靠的科学依据。为了澄清这一历史科学问题,笔者对河西走廊草原牧区正在流行的牲畜中毒地方病进行了野外调查,分析了该区草原生态环境植物、土壤中硒的含量。结果表明:①棘豆植物是马可波罗记载的引起牲畜中毒的毒草;②棘豆植物根部土壤与世界平均土壤硒含量相近;③棘豆属毒草硒含量远低于能导致一般动物中毒的3 mg/kg植物硒风险值。由此推断,引起《马可波罗游记》中记载的中国西部肃州牲畜毒草中毒并非硒中毒,中毒的原因是棘豆植物中的生物碱成分苦马豆素(Swainsonine)。
