1. Results: The nurses lack hydrargyrum knowledge.

2. Methods:The concentration of hydrargyrum aminochloride was measured by surplus titration.

3. This method can be used for hydrargyrum determination of water samPles.

4. The main pollution source of the hydrargyrum of vegetable and soil is the atmosphere dust of factory and gas in the Harbin's greenbelt.

5. Objective In order to establish determination method for Hydrargyrum in Salt.

6. Objective:To prepare compound hydrargyrum aminochloride cream and carry out its quality control standard.

7. Objective: To investigate the understanding of hydrargyrum knowledge in clinical nurses in order to enhance occupational prevention.

8. Joint-toxicity of copper and hydrargyrum on tadpole was studied in the present investigation.

9. Method of mensurating soil Arsenic and Hydrargyrum simultaneously using microwave digestion hydride - atomic fluorescence spectrometry was setup.

10. In this study, we reported major heavy metal residues such as chrome, copper, cadmium, hydrargyrum, lead, zinc, metalloid in comb scallop,() which live besides Shandong province.

11. The analytical technique, hydride generation-atomic fluorescence spectrometry(HG-AFS), is used to determine hydrargyrum and arsenic in water sample simultaneously.

12. The effect of FS content on membranes porosity has been discussed through measuring the porosity by hydrargyrum pression method.

13. The results indicated that the method developed was effective and reliable for the determination of hydrargyrum that was mostly located in zinco , zinc and carbon complexity.

14. Analyzed experiment data, the best one is ultrasonic in the light of convenience, quick, especially avoid sample color disturbing and hydrargyrum pollution.

15. Methods The data of the casting film, electron microscope scanning, hydrargyrum driving text and X-diffraction were analyzed.

16. It can be concluded from the evaluation numbers that the safety of Ming river is difference, iron and hydrargyrum are the main pollutants; the safety of Tuo river and Fu river are better.

17. Conclusions It was concluded that the method is suitable for Hydrargyrum determination in salt.
