- Abstract
Anabaena cylindrical, L a blue green alga commonly found in rice fields was experimentally exposed with a board spectrum insecticide,Endosulphan,EC-35 in laboratory conditions for varied days. After exposure of the test alga, the parameters like total nitrogen content, cellular nitrogen and extra-cellular nitrogen were estimated to study the toxic effect and the subsequent recovery from insecticide stress. The results obtained indicated decrease in all studied parameters with increase in exposure period and concentration. The highest concentration (3.25ml/L) and highest period (15Days) severely affected the nitrogen related parameters, However, when the algae were allowed to grow in insecticide free environment for 15 days, they could able to recover fully from the toxic stress.
