Effects of Industrial Solid Waste Toxicityon Different Harvesting Days of Solanum melongena L.

Abstract

The Industrial solid waste samples were collected at the outlet of release channel of the “Oil and Gas Industry” at Kakinada, air-dried and was brought to the laboratory. The soil amendments were prepared for as Control, Amendment 1,2,3 and 4. The RGR values of Control plants recorded on 21-51, 51-81 and 81-95 day growth periods were 0.0921, 0.0460 and 0.0095 mg/g/d respectively. Both control and A1, A2, A3 and A4 soils showed an insignificant decreasing trend in RGR over the harvesting periods. The relative growth rate in A1, A2, A3 and A4 soils did not exhibit any definite pattern of variation. The high toxicity levels of the Copper, Zinc, Iron and Manganese heavy metals were accumulated in the industrial solid waste. The results of this study stress the need for environmental awareness, adequate regulations and proper management of waste sites by the local municipal authorities and Pollution control board take the necessary actions to control Industrial solid waste disposal site on the Kakinada, Andhra Pradesh and India.
