Mr. Lynde has conducted research for clients on a variety of environmental issues.

He has extensive background in both sediment and aqueous phase toxicity testing using novel as well as EPA approved protocols. Some non-standard test approaches include various life stages (juvenile and glochidia) of native mussel species. His background in ecotoxicology led to the development of sediment and aqueous phase toxicity tests for juvenile Asian clams.
