Abstract/ Executive Summary:

Zinc is an essential element needed by the body in small amounts as it is the most abundant trace metals in human. It deficiency is occurring in different climate regions of the world. It has become an important risk factor for plant growth as well as human health throughout the world. In this study, we observed the amount of zinc in different arums, bananas, vegetables and pulses which are locally available in Chittagong region of Bangladesh. The amount of zinc in twenty samples of arums was found to vary from 0.3174-9.0755 µg/g. The highest and lowest value was found in arums of Typhonium trilobatum (Patiya) and Amorphophallus campanulatus (Satkaniya) respectively. In bananas vary from 0.1430 to 2.7360 µg/g. The highest and lowest value was found in banana of Musa acuminata in Satkania and Ramgarh Upazila respectively. The amount of zinc in vegetables was found to vary from 0.92-7.59 µg/g. Zinc in pulses was found to vary from 1.2973- 29.5008 µg/g. The highest and lowest values were found in Lathyrus sativus and Phaseolus aureus respectively. From four types of food, we see that the highest value of zinc in pulse species of Lathyrus sativus and the lowest value of zinc in banana species of Musa acuminata respectively of Chittagong region, Bangladesh.

Keywords: Zinc, Arum, Banana, Vegetable and Pulse.

Location: Five Upazila of Chittagong region in Bangladesh

Program Area: Crop-Soil-Water Management

Commodity: Zinc

Objectives:

Chittagong is the commercial capital city of Bangladesh. Many types of Industry were built in this city. For that reason, we try to find out the amount of zinc from various substances. The climate of Bangladesh is proper for growing of various arums, bananas, vegetables and pulses. The people can easily collect arums, bananas, vegetables and pulses from local market by cheap rate or they can grow easy way to this arums, bananas, vegetables and pulses. Various arums, bananas, vegetables and pulses are contains various amount of zinc. In the present investigation, the amount of zinc in some arums, bananas, vegetables and pulses are determined by spectro-photometric method.

Methodology:

All samples were washed with water followed with DDI (double deionized distil water). Samples were cut into small pieces and dried at 105⁰C for 18 hrs. After drying, the samples were burned into the maffle furnace and then the ashes were weighed and stored in the stopper bottle. Taking the weight of the ash sample, the amount of Zn present in the sample was determined by using conventional methods.

Achievement/Findings:

Bangladesh is a densely populated and an agricultural country. Currently, the population is 16 crore and the area is 1,47,570 square kilometer. Most of the peoples of our country are poor and they live in village. So, they cannot buy zinc sufficient food. Zinc deficiency has been associated with dermatitis, anorexia, growth retardation, poor wound healing, hypogonadism with impaired reproductive capacity, impaired immune function and depressed mental function etc. It may also have an impact on carcinogenesis. The persons, who suffer from zinc deficiency, can get relief of their diseases by selecting zinc-rich arums, bananas, vegetables and pulses. The study shows the amount of zinc is very higher in the Lathyrus sativus pulse of Anowara Upazila and lower in Musa acuminata banana of Ramgarh Upazila. The reason for this trend is because of high translocation and transpiration rate of pulses in which transfer of metals from root to stem and ultimately to fruit. If they are unable to buy arums, bananas, vegetables and pulses from the market then they can grow such arums, bananas, vegetables and pulses in their garden or field. This analysis provides a baseline data for our efforts directed towards maintaining a healthy life style.
