Fluorosis and arsenicosis： An update     

Lakshmi Narasimharao Kodali Jagadiswararao Ramayanam 《中国地球化学学报》2006,25(B08):65-65

Endemic fluorosis, caused by excess fluoride in water, is widespread in the arid and semiarid tracts of India. This disorder is of recent origin and developed due to certain faulty water management practices. After Eager reported ‘dental mottling＇ among emigrants from Pozzuli in Italy in 1901, several such reports came from all over the world. From 3 works published independently from Pennsylvania, Arizona and South Africa in 1931, it was known that this disorder is caused by drinking water containing over 1 mg/L fluoride during formation of permanent teeth among children.‘Skeletal fluorosis/Osteofluorosis＇, affecting bones and joints among adults was reported by Moeller and Gudjonsson in 1932 due to accumulation of fluoride in hard tissues by drinking water with over 7 mg/L fluoride for several years. In course of time fluorosis has been reported in over 22 countries from all over the world. Fluorosis spreads now among 67 million people in the entire arid and semiarid tracts of India. The work of National Institute of Nutrition of India at Hyderabad in 1977 revealed the spread of endemic ‘genu valgum＇ （knock-knee） crippling lower limbs right from childhood in association with fluorosis in most parts of India. Although preliminary work revealed that genu valgum is caused by drinking waters poor in calcium and rich in molybdenum, efforts these disorders by supplying low-fluoride water should be taken up to know its exact cause to the communities could not so eradicate The governmental efforts to eradicate the problem.  相似文献   

Brick tea and its health impact     

Hairong LI Qinbin LIU Wuyi WANG Xuehui LIU Hailong LI Shuhai LI Xiaoyu ZHAO Lizhen WANG 《中国地球化学学报》2006,25(B08):73-74

Tea bush is one of the plants cultivated in acidic soil, and is a typical hyper-accumulator of F and Al. Brick tea is a kind of brick-formed tea compressed using the older and coarse leaves and branches of tea trees. Brick tea mixed with milk is drunk as a daily indispensable beverage for Mongols, Ewenki, and other minority nationalities in the pastoral and semi-pastoral areas of Northwest China. It is reported that drinking brick tea can result in dental and skeletal fluorosis due to the high F content in it. Because Alzheimer＇s disease （AD） is related with Al in human brain, and Al has potential toxicities for skeletal and neural systems,  相似文献   

保障饮水安全维护生命健康     

韩子夜 《水文地质工程地质》2005,32(4):i001-i001

我国是地方病流行较为严重的国家，地方病分布广泛，受害人口较多。由于自然环境影响。地方性砷中毒、地方性氟中毒、克山病、大骨节病以及地方性甲状腺肿等．在“老少边穷”地区及部分农村地区仍很严重。无疑，地方病严重影响了当地人民群众的生命健康和正常生活．并严重阻碍了建设小康社会的步伐。  相似文献

河西走廊棘豆毒草中的硒及其与牲畜中毒关系研究     

邵树勋  郑宝山  赵成章  殷翠琴  朗永斌  张爱玲 《地球科学进展》2004,19(13):502-505

河西走廊地区草原生态环境，棘豆等毒草泛滥成灾，导致大量牲畜中毒死亡。棘豆毒草导致的牲畜中毒症状与历史上马可波罗记载的古代肃州牲畜毒草中毒症状及其相似。为了确定马可波罗所记载的肃州牲畜毒草中毒是否与硒有关，本项研究对河西走廊地区主要草原畜牧区肃南县草原发育的棘豆属植物及其土壤中的硒进行了测定，测定结果表明：土壤硒含量平均值为 0．205± 0．173m g／kg，与世界平均土壤硒含量相近。棘豆属植物小花棘豆根、茎叶的硒平均含量分别为 0．112±0．038m g／kg（0．052～0．174m g／kg），0．102±0．027m g／kg（0．066～0．158 m g／kg）；黄花棘豆全株硒平均含量为 0．066±0．009m g／kg（0．058～0．078m g／kg），种子硒：0．107m g／kg。可见该区棘豆属毒草硒含量远低于能导致一般动物中毒的 3 m g／kg植物硒含量。根据肃南县棘豆毒草发育的地理位置、牲畜中毒症状调查及其硒含量测定的结果，本文认为马可波罗所记载的中国西部肃州牲畜毒草中毒是棘豆属毒草中毒，其主要毒素成分不是硒。  相似文献   

中国西南部居民的氟中毒和环境地球化学     

Zheng  BS 束龙仓 《世界地质》1991,10(1):163-165

地方性氟中毒已被世界许多国家和地区所熟知,它也危及着许多中国居民的健康,到目前为止,关于氟中毒的实例报道大都起因于饮用高氟浓度的地下水。然而,根据作者的调查,中国西南部居民中发现的氟中毒情况是由于在室内烧煤而造成,食物和空气污染而至。作者对这一类型的氟中毒区,从致病途径和规律等方面进行系统的环境特征研究。  相似文献   

肯尼亚饮用水对牙齿氟中毒的影响     

葛秀珍 《水文地质工程地质技术方法动态》2002,(4):7-8

研究区域位于肯尼亚裂谷，包括纳库鲁区的恩乔罗，覆盖面积774km^2。发现岩石、植物、动物、空气和水中有浓度不等的氟化物出现。因为它有很高的活性，氟化物通常以离子形式存在，并通过空气的吸收、吸入物进入水体。水中合的氟化物比食物中合的氟化物更快地被吸收。氟化物被人体吸收后，如果没有排泄出去，能引起牙齿和指甲的细沟、牙的氟中毒或长期处于高氟浓度的环境中，能引起骨胳的氟中毒。  相似文献
