Impact of Copper Algaecides on Eutrophication and Shellfish Safety

Full Title: Exploring the potential for upstream Copper-based algaecide application to exacerbate downstream eutrophication and compromise shellfish production and safety
This project explores the effects of copper-based algaecides on downstream eutrophication and shellfish safety in Florida estuaries. It aims to assess copper contamination in bivalves and sediments, evaluate its impact on bivalve filtration efficiency, and develop a statewide database to inform conservation efforts.

Project Abstract:

The project investigates the impact of copper-based algaecides, commonly used in Florida to control algae, on downstream eutrophication and shellfish safety. Copper accumulation in estuaries poses risks to bivalves like oysters and mussels, which are crucial for maintaining water quality through their filter-feeding and denitrification activities. The study aims to assess copper contamination levels in bivalves and sediments, evaluate the effects of copper on bivalve filtration efficiency, and build a statewide database of copper levels. The research is expected to enhance understanding of copper pollution’s ecological impacts, inform regulatory agencies, and guide future conservation efforts.
