Abstract

In the present investigation the authors made an attempt to study the detoxifying impact of Chlorella vulgaris and Spirulina platensis on sub-lethal and lethal Mercury and Lead caused enzyme variations (Phosphoglucomutase and Hexokinase) in various brain regions (Cerebrum, Diencephalon, Cerebellum and Medulla oblongata) of three fresh water teleost i.e. Labeo rohita, Clarias batrachus and Channa punctatus on a comparative approach from a tropical environment. The enzymes fall in presence of heavy metal and rise in presence of detoxifying autotroph and was highest in L. rohita than C. batrachus and C. punctatus. Among the brain regions, it is the diencephalon at 16 hours registered maximum enzyme variations and minimum at 8 hours in cerebellum. Between the metals, mercury was more toxic than lead. Between the autotrophs, it is Chlorella vulgaris proved as an effective detoxifying agent than Spirulina. The recorded variations were discussed in detail.
