Information on the W content in environmental matrices is desired. Because of the antagonistic effect of W on Mo nutrition of plants and microorganisms, this study was conducted to assess the concentration of W in soils, plant materials, and sewage sludges in Iowa. Results showed that the total W in 18 soils ranged from 0 to 2 mg kg −1 , with mean and median values of 0.89 and 0.88 mg kg −1 , respectively. The corresponding values for 22 plant materials ranged from 0 to 0.35 mg kg −1 , with mean and median values of 0.18 and 0.17 mg kg −1 . Analysis of 44 sewage sludge samples from different wastewater‐treatment plants in Iowa showed that the concentration of this element varied from 0.5 to 62 mg kg −1 , with mean and median values of 4.3 and 2.2 mg kg −1 , respectively.
