Screening of Allelopathic Activity of Momordica dioica and Mukia maderaspatana
Abstract: ABSTRACTAllelopathy is a chemical process which a plant uses to keep other plants from growing too close or away from it. Allelopathy refers to the chemical inhibition of one species by another. The “inhibitory” chemical releases into the environment where it affects the development and growth of neighboring plants. In the present investigation to check the allelopathic activity, two plants of family Cucurbitaceae were selected, i.e., Momordica dioica Roxb. ex …

Impact of Hexavalent Chromium on Histopathology in Freshwater Stinging Catfish Heteropneustes Fossilis
Abstract: Acute toxicity of Cr (VI) (as K2Cr2O7) to freshwater stinging catfish, Heteropneustes fossilis and its histopathological impacts on gill and liver tissue were evaluated. Fish showed behavioral alterations after K2Cr2O7 exposure and 96 h-LC50 was 35.724 mg/L in static bioassay. Fish were exposed to three sub-lethal concentrations (concentration I=1/4th of 96 h-LC50, concentration II=1/10th of 96 h-LC50 and concentration III=environmental concentration of Cr reported in the river Buriganga). Blood, liver …

Toxicity Evaluation of a Few PAHs on a Local Freshwater Fish—Rasbora daniconius
Abstract: Polycyclic Aromatic Hydrocarbons (PAHs) have become ubiquitous pollutants of water resulting mainly from petroleum products. These are absorbed into the living systems and converted into secondary metabolites which show bioaccumulation in the living systems and have several deleterious effects on them. The present study attempts to evaluate toxicity of two such PAHs— Naphthalene and Anthracene—on the freshwater fish, Rasbora daniconius, using pure PAHs dissolved in dichloromethane. LC50 values were seen …
