Question: 5. Concentrations Of Polychlorobiphenyls (PCBs) In Lake Sediment Cores Tend To Be Relatively High And Exhibit Patterns Of Concentration Versus Depth (age) That Reflect Patterns Of PCB Input Into The Lake System. However, Levels Of A Widely Used Herbicide, Atrazine, In Lake Sediments Are Typically Very Low Relative To Concentrations In Lake Water Explain …
