A Study of Zinc Metal in Industrial Effluent of Bikaner City and its Impact on Various Plants and Crops

Abstract

Zinc occurs naturally in air, water and soil, but zinc concentration are rising due to accumulation of zinc through human activities. It is a micronutrient which is required in 0.3 ppm range in water for optimum growth of plants and crops. It plays a vital role in plant physiology and its deficiency causes various disorders in plants like smaller leaves, slow growth of plant, chlorosis, poor nitrogen formation in legumes, etc. To analyze zinc metal, ten samples were collected from various stations of the field and analyzed on atomic absorption spectrophotometer. All the samples shows very low level of zinc ranging from (0.05 to 0.15 ppm).
