Confiscation of heavy metal residues in cauliflower using washing solutions

摘要

The heavy metals are a major category of globally distributed pollutants of soil and water by domestic sewage and industrial discharge. The irrigation with waste water is recognised to contribute potentially the heavy metal contents to the soil and ultimately in vegetables. The vegetables play a very vital role in maintaining the nutritional status of humans. The production of food and maintaining its quality is the foremost matter throughout the world. Heavy metals have the tendency to accumulate in cauliflower through uptake from soil, water and atmosphere. The heavy metals intake through diet causes many disorders like nervous system issues, kidney disorders, bone diseases and reproductive problems. The present project was designed to determine the mitigating impact of washing techniques on the heavy metals such as lead, arsenic, zinc and mercury in cauliflower grown under controlled field trails. The quantities of heavy metals were determined in fresh and chemically washed cauliflower with the help of Atomic Absorption Spectrophotometer. The calculated amount of these heavy metals was compared to their maximum residues limits. The results were discussed using standards statistical procedures.
