Raman Spectroscopy Detects Herbicides in Water ANN ARBOR, Mich. -- Researchers at the University of Michigan have employed Raman spectroscopy to measure two herbicides in water. The herbicides, paraquat and diquat, contain chemicals that cause plant cell damage. Detecting the herbicides is important because both reach into the soil, contaminating nearby water supplies. The US Environmental Protection Agency has set the acceptable level for diquat at 20 parts per billion and paraquat at 60 parts per billion in drinking water. To monitor contamination, scientists have traditionally employed two...Read full article
