Abstract

An assessment of dietary risk of heavy metals exposure to human is important since it is the main of exposure. The aim of study to measure the contamination of lead and mercury in juaro fish meat and the effort to reduce contaminations using citric acid from pineapple extract as a chelating agent. Samples was soaked and boiled in citric acid extract at concentration 50%, 75 %, 100 % for, 15 min, 30 min, 45 min at 25 0C, 50 0C and 100 0C. The concentration of lead and mercury in Juaro fish lower than the maximum acceptable lever for Pb and Hg respectively (1mg/kg for Pb, 0,5 mg/Kg for Hg). The result indicated that after soaking and boiling in citric acid solution form pineapple extract at concentration 100 % for 45 min at 100 0C reducing heavy metals Pb from 0,02 mg.Kg-1 to 0,003 mg.Kg-1 and Hg from 0,011 mg.Kg-1 to lower than 0,0001 mg.Kg-1. The increasing of soaking time and boiling temperature, the levels of Pb and Hg in Juaro fish Tissue will decreasing.

Abstract

Selection of the wrong type of examination sample can affect the results of the examination. Examination of blood cell counts can be taken from venous blood and capillary blood, but in capillary blood sampling there can be a dilution of the blood by tissue fluid so that the results of the blood cell count allow for differences between capillary blood samples and venous blood. The purpose of this study was to determine the difference in the number of platelets in venous blood and capillary blood in a hematology analyzer. This type of research is descriptive-analytic. Examination using Sysmex KX-21 with Blood Cell Counter method. All data were tested for normality using Shapiro-Wilk and hypothesis testing using Independent Sample T Test. The results of the examination showed a significant difference, where the platelet count of the capillary blood was lower than that of the venous blood and statistically showed a significant difference in the number of platelets with a value of =0.01 (<0.05). So it can be concluded that there are differences in the number of platelets in venous blood and capillary blood.
