Abstract
The impact of cement dust on different biochemical parameters viz chlorophyll, phaeophytin, caroteniod free sugar, starch, amino acid and proteins were studied for a period of one year. All the parameters except amino acids showed a remarkable decrease as compared to control. Total chlorophyll content decreased by 91% and 83%, total phaeophytin by 86% and 76%, cartoeniod by 70% and 56%, Starch by 33% and 11%, free sugar by 17% and 6% and protein by 28% and 19% respectively at 50m and 100m away sites as compared to control. The amount of amino acid showed an increase of 13% and 5% at the same sites as compared to control.
