Production And Characterization Of Twelve Different Biochars And Evaluating Their Effects On Soil Health And Plant Growth, Shagufta Gaffar
Production And Characterization Of Twelve Different Biochars And Evaluating Their Effects On Soil Health And Plant Growth, Shagufta Gaffar
FIU Electronic Theses and Dissertations
Biochar has been a topic of growing interest in the scientific community. It is a product derived from carbon rich organic materials through the process of pyrolysis. It has received wide attention as a means to improve soil fertility and crop productivity, absorb pollutants in soil, and sequester carbon to mitigate climate change. Recent research on biochar explores its impacts on the environment with particular focus on use as a soil amendment in agriculture. Biochar produced from different biomass and under different production process effects the environmental and agronomic impacts of its application in different ways. This means biochar can …

Mono- and tri-vanadium-substituted Keggin-type heteropolyoxoanions [SiW12O40]4- and[PW12O40] 4- were evaluated as photocatalysts for the photodegradation of three hazardous food pesticides: Atrazine, Chlorpyrifos and Dieldrin. Kinetic experiments were performed under UV irradiation at 254nm. The degradation of each pesticide was assessed by investigating its disappearance with time using High Performance Liquid Chromatography c o n n e c t e d to an Ultra-Violet s p e c t r o p h o t ome t e r d e t e c t o r (HPLC-UV). The photocatalytic degradation of the three pesticides exhibited first order kinetics. It was …

Effects Of The Herbicide Atrazine On Members Of The Freshwater Genus Hydra, James Dal Santo
Biology: Student Scholarship & Creative Works
Atrazine is a commercially available herbicide with known effects on the hormone levels in frogs and several other organisms. This effect has not been significantly studied in invertebrates, even though observing invertebrate levels represent a very common assay the health of a freshwater ecosystem. To study the effects of atrazine in invertebrates, hydra were subjected to environmental (10 μg/L) and high (400 μg/L) concentrations of atrazine and observed for changes in fertility and reproduction over a period of four weeks. No significant changes in fertility or reproduction were found at high concentrations, and environmental concentration testing is currently in progress, …
