莱伯泰科QuickTraceTM 测汞仪(汞分析仪)

土壤是农业生产和人类生存的主要载体和生态环境的重要组成部分，其质量好坏与人们生活息息相关。然而近年来，随着我国经济和社会发展，土壤污染日益严重， 已成为严重的生态问题。土壤污染是指进入土壤中的有害、有毒物质超出土壤的自身净化能力，导致土壤的物理、化学和生物学性质发生改变，直接影响土壤生态系统的结构和功能，导致生产力退化，并最终对生态安全和人类生命健康构成威胁的现象。土壤污染主要是人为造成的污染源，如“三废”的排放，即废气、废渣、废水，还有过量使用农药、化肥、重金属、微生物、化学物品等。 土壤污染具有隐蔽性、潜伏性和长期性，特别是土壤中重金属的污染基本上是一个不可逆转的过程，土壤重金属被植物吸附和积累后，通过食物链富集到人和动物体中，从而危害人畜健康引发癌症等疾病，如水俣病、骨痛病等。同时被污染土壤中的重金属会通过风力、地表径流、淋溶作用等进入大气和水体中，导致大气、地表水、地下水污染和生态系统退化。由于进入土壤中的重金属污染物以可溶性与不溶性颗粒存在，因此残留率很高，如镉、铜、锌、铅等可达85-95%，有些元素甚至会被植物吸收在其体内累积，如铬；另外，各种有机物污染也让人触目惊心。因此如何快速、准确地测试土壤中有害重金属元素及有机污染物显得尤为迫切。为此，Labtech公司提出了检测土壤中的有机物及重金属元素的前处理解决方案。

Total mercury determination in water allows quantitation for many different applications.The goal is to validate the QuickTraceTM M-8000Mercury Analyzer Absorption Spectrometer by analyzing SRM 1641c,Mercury in Water.

Mercury detection in soil play a critical part in agriculture,human health,and overall environmental status.It allows for both long-term and short-term momitoring of each of each of these delicate systems,and gives information on the specific sources of mercury contamination.

Seawater analysis is a crucial part of environmental monitoring.However,it can present many obstacles for the analyst.It is a powerful to of used to gather information regarding the ecosystem.Contamination are a few of the major obstacles that can arise when monitoring mercury at this level.Mercury is prevalent through point source contamination that often comes from industry and bio-accumlation.

Total mercury determination in water allows quantitation for many different applications.The goal is to validate the QuickTraceTM M-7500 Mercury Analyzer Absorption Spectrometer by analyzing SRM 1641c,Mercury in Water.

Mercury analysis at the low level in seawater can present many challenges for environmental monitoring.Seawater analysis allows for quantitative date to be obtaned.It is a powerfull tool used to gather onformation regarding the ecosystem.

Mercury analysis of foodstuffs is a crucial part of enviromental monitoring.Various forms of mercury form soil,air and surface water resulta in bioaccumulation in plants as well as other forms of vegetation.Bio-accumulation occura either through absorption of mercury through the leaves from the atmosphere or through the soil into the root system.

Total mercury measurement in foodstuffs is an important analytical tool.Mercury bioaccumlation can occur either though absorption of mercury through the leaves form theatm of mercury through the soil into the root system.Mercury contamination in the soil can come from agricultural land,municipal sludge and industrial wastes.
