Aqueous media encountered in the natural environment often contain suspended solids that can interfere with spectroscopic measurements, yet removal of these solids, for example, via filtration, can have even greater adverse effects on the extent to which subsequent measurements are representative of actual field conditions. In this context, this study focuses on evaluation of turbidity effects on Raman spectroscopic measurements of two common environmental pollutants in aqueous solution: ammonium nitrate and trichloroethylene. The former is typically encountered in the runoff from agricultural operations and is a strong scatterer that has no significant influence on the Raman spectrum of water. The latter is a commonly encountered pollutant at contaminated sites associated with degreasing and cleaning operations and is a weak scatterer that has a significant influence on the Raman spectrum of water. Raman observations of each compound in aqueous solutions of varying turbidity created by doping samples with silica flour with grain sizes ranging from 1.6 to 5.0 \u03bcm were employed to develop relationships between observed Raman signal strength and turbidity level. Shared characteristics of these relationships were then employed to define generalized correction methods for the effect of turbidity on Raman observations of compounds in aqueous solution. <\/jats:p>","DOI":"10.1366\/13-07292","type":"journal-article","created":{"date-parts":[[2014,11,26]],"date-time":"2014-11-26T21:11:10Z","timestamp":1417036270000},"page":"1381-1392","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":18,"title":["Assessment and Correction of Turbidity Effects on Raman Observations of Chemicals in Aqueous Solutions"],"prefix":"10.1177","volume":"68","author":[{"given":"Joseph V.","family":"Sinfield","sequence":"first","affiliation":[{"name":"School of Civil Engineering, Purdue University, West Lafayette, IN 47907 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chike K.","family":"Monwuba","sequence":"additional","affiliation":[{"name":"Environmental Resource Engineering Department, Humboldt State University, Arcata, CA 95521 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2014,12,1]]},"reference":[{"key":"bibr1-13-07292","doi-asserted-by":"publisher","DOI":"10.1366\/0003702981942807"},{"key":"bibr2-13-07292","doi-asserted-by":"publisher","DOI":"10.1061\/(ASCE)1090-0241(1999)125:12(1072)"},{"key":"bibr3-13-07292","doi-asserted-by":"publisher","DOI":"10.1111\/j.1745-6592.2001.tb00647.x"},{"key":"bibr4-13-07292","first-page":"54","volume-title":"Trans.
