Fate of ethylenethiourea in Hawaiian soil and water

Ethylenethiourea (ETU) degradation rates and products in soil and groundwater were determined by using standard and isotopically labeled ETU (4,5-(14)C2, 1,3-(15)N2, and 2-(13)C). ETU is rapidly degraded and detoxified to ethyleneurea (EU) and sulfate ion in the soils studied by chemical oxidation,...

Zusammenfassung:	Ethylenethiourea (ETU) degradation rates and products in soil and groundwater were determined by using standard and isotopically labeled ETU (4,5-(14)C2, 1,3-(15)N2, and 2-(13)C). ETU is rapidly degraded and detoxified to ethyleneurea (EU) and sulfate ion in the soils studied by chemical oxidation, possibly by hydroxyl radicals. EU is further degraded by soil microorganisms to ethylenediamine and CO2-ETU degraded very slowly in groundwater, but the rate increased significantly with addition of basalt. BTU should not reach deep groundwater because of rapid breakdown in overlying soils.
