The Influence of Cadmium Heavy Metal on Vitamins in Aquatic Vegetables

Abstract

Normal 0 false false false IN X-NONE X-NONE MicrosoftInternetExplorer4 The absorption of cadmium heavy metal in 3 (three) kinds of aquatic vegetables; water lettuce ( Linnocharis flava ), water convolvulus ( Ipomoea aquatic Forsk ) and watercress ( Nasturtium officinale R. Br) is studied to determine the influence of the contents of vitamins A and C. The purpose of this research is to identify the accumulation of cadmium in the organs of the aquatic vegetables, and their influence to the contents of vitamins A and C. This research is conducted by employing the factorial experimental design of randomized block design (RBD) with 3 (three) factors. The data are analyzed by regression to detect the correlation and contribution of cadmium influence on the aquatic vegetables. The accumulation in the 3 (three) aquatic vegetables mainly occurs in the stems and leaves. The longer the harvest time is , the higher the accumulation will be. Water lettuce has the highest accumulation of cadmium, followed by water convolvulus and watercress has the least . Cadmium is responsible for the declining levels of vitamins A and C. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} Keywords: accumulation, aquatic vegetables, cadmium, heavy metal, vitamin /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}
