Toxicity assessment of agrochemical Almix in through histopathological alterations.

The present study was designed to assess the adverse effects of the agrochemical Almix on comparative basis in gill, liver and kidney of through histological and ultrastructural observations under field (8 g/acre) and laboratory (66.67 mg/L) conditions. Exposure duration of both experiments was 30 days.

Acute Toxicity and Oxidative Stress Responses in Tadpole of Skittering Frog, Euphlyctis cyanophlyctis (Schneider, 1799) to Sodium Fluoride Exposure.

This study evaluated the acute toxicity and oxidative stress responses to sodium fluoride (NaF) exposure in tadpoles of the skittering frog, Euphlyctis cyanophlyctis (Schneider 1799). The 96 h LC value was found to be 647 mg/L. Biochemical tests were conducted at 10%, 20%, 30%, 40%, 50%, 60%, 70% and 80% of the 96 h LC dose.

Evaluation of metal contamination and phytoremediation potential of aquatic macrophytes of East Kolkata Wetlands, India.

Objectives: The present study analyzes metal contamination in sediment of the East Kolkata Wetlands, a Ramsar site, which is receiving a huge amount of domestic and industrial wastewater from surrounding areas. The subsequent uptake and accumulation of metals in different macrophytes are also examined in regard to their phytoremediation potential.

Methods: Metals like cadmium (Cd), copper (Cu), manganese (Mn), and lead (Pb) were estimated in sediment, water and different parts of the macrophytes and .

Toxic effects of glyphosate-based herbicide, Excel Mera 71 on gill, liver, and kidney of under laboratory and field conditions.

The effects of glyphosate-based herbicide Excel Mera 71 under field and laboratory conditions were investigated to evaluate the pathological symptoms through light and electron microscopic study in the gill, liver, and kidney of (Bloch) for a period of 30 days. Histological alterations like hypertrophy and fusion in secondary lamellae, damage in chloride cells were more prominent in laboratory conditions under light microscopy. Topological changes such as complete loss of microridges, swelling, and irregular arrangement of microridges in the gills were prominent under scanning electron microscopic study under laboratory conditions.

Effects of almix herbicide on profile of digestive enzymes of three freshwater teleostean fishes in rice field condition.

The present investigation was carried out to compare the alterations of digestive enzymes like amylase, lipase, and protease activities in three teleostean fishes ., , and after application of almix herbicide for 30 days at rice field concentration , 8 g/acre. Highest amylase activity was observed in intestine of (300.
