Capacity and mode ofPCB metabolism in small cetaceans. Toxicity of the herbicide glyphosate and several of its formulations to fish and aquatic invertebrates.
Other studies have identified the ability of some of these compounds to undergo short-range atmospheric transport Muir et al. We know that the use of pesticides is a proven and that it works properly.
Significant changes were noticed in the ECG, the serum LDH levels, and cholinesterase ChE activities in the spraymen, indicating cardiotoxic effects of methomyl. " Haas School of Business University of California Berkeley.
