Does Selenium Offset Methylmercury Toxicity Across Trophic Levels in Chlorella Pyrenoidosa and Aeolosoma Variegatum?
Husnah Azmi
Abstract:Methylmercury is a potent neurotoxin that impairs functioning of the nervous system, and selenium is known to provide a protective effect against methylmercury. Experiments were run to investigate the offsetting of methylmercury toxicity by selenium across trophic levels at the base of the aquatic food chain. A primary producer, Chlorella pyrenoidosa, was exposed to methylmercury in the presence or absence of selenium. The subsequent biomass was fed to a primary consumer, Aeolosoma variegatum. Results showed t… Show more
