Assessment of Arsenic Toxicity in Spinacia Plant: Physiological Aspect

Urvashi Sinha

Abstract

Arsenic (As) is a chemical element which has become environmental toxin now days due its presence in large concentration in water and soil. It remains in the environment for an extensive period. Although it is a non-essential element for plant, the rooted plants absorb Arsenic from the soil. Even a trace amount of Arsenic is enough for affecting the plant growth and development. Test sample Spinacia sp. is a green leafy vegetable that belongs to the family Amaranthaceae. It is distributed all over the world. It is a good source of minerals, vitamins, ascorbic acid, carotenoids, phenols and omega 3fatty acid, therefore, called as the power house of nutrients. Background soil prepared with the Arsenic level 0.013mg/kg, treated with three different concentrations of Arsenic 0.02 mg/l, 0.06mg/l and 0.08mg/l showed marked changes in the physiology of test sample in the retention period of 30 days. Percent germination was recorded as 16.6% in the soil containing 0.08mg/l. Synthesis of chlorophyll a and chlorophyll b was recorded on 5th, 15th and 30th day. It was estimated highest 44.343 mg and 17.837 mg in the sample plant grown at the lowest concentration of Arsenic (0.02 mg/l) in the soil. Significantly, this research work addresses the physiological aspect and the results provide scientific understanding of this research area of Arsenic toxicity in soil plant systems.
