Assessment of copper in diverse pulses, bananas, vegetables and arums of five upazila of Chittagong area in Bangladesh by spectro-photometric method

Copper is common element in the environment. People are exposed to copper by breathing air, drinking water, eating food, and by skin contact with soil, water and other copper-containing substances. Most copper compounds found in air, water, sediment, soil and rock are strongly attached to dust and dirt or imbedded in minerals. It rapidly enters into the bloodstream and is distributed throughout the body after eating or drinking the copper containing products. Certain substances in foods are eaten with copper can affect the amount of copper that enters into the bloodstream from the gastrointestinal tract. The present investigation shows that four verities of vital food i.e. pulses, bananas, vegetables and arums contain diverse amount of copper in Chittagong area of Bangladesh. This food is taken for survival the life. The amounts of copper in pulses were found to vary from 3.2250-29.6531μg/g of that region. The highest and lowest values were found in Vigna muungo (Anowara) and Lathyrus sativus (Mirsharai) respectively. The amounts of copper in bananas were varied from 0.595-7.861 μg/g and the highest and lowest values were found in banana of Musa paradisiaca but two different upazila i.e. Lama and Satkania respectively. The amounts of copper in vegetables were found to vary from 1.16-15.13 μg/g. In this case, the highest and lowest values were found in Centella asiatica (Pahartali) and Alternanthera philoxeroides (Fatickchari) severally. The amounts of copper in twenty samples of arums were observed to vary from 0.8298-49.7008 μg/g. The highest and lowest value was found in Colocasia esculenta (Patiya) and Amorphophallus campanulatus (Satkaniya) respectively. Finally, the analysis of four types of food were investigated that the highest value of copper is present in Colocasia esculenta (Patiya) and the lowest value of copper in Musa paradisiaca (Satkania) respectively.
