Soil Phosphorus Storage Capacity for Environmental Risk Assessment

Phosphorus retention capacity in red ferralitic soil.

In this study the main physical-chemical characteristics of red ferralitic soil to use as substrate in subsurface wetlands was determined. The P-removal was evaluated in a short-term isotherm batch experiment and in a column percolation experiment. The acid characteristic and high content of iron minerals in the red ferralitic soil facilitated the phosphorus removal. Also the sorption isotherms...

Soil phosphorus saturation ratio for risk assessment in land use systems

*Correspondence: Vimala D. Nair, Soil and Water Science Department, University of Florida, PO Box 110290, 2181 McCarty Hall A, Gainesville, FL 32611, USA e-mail: [email protected] The risk of phosphorus loss from agricultural soils can have serious implications for water quality. This problem has been noted particularly in sandy soils in several parts of the world including Europe (e.g., the Netherla...

Risk Assessment for Environmental Health

This comprehensive and easy-to-read treatment of the various facets, history, and criticisms involved in risk assessment for environmental health focuses on tools and approaches used for humans in an environment involving potential chemical hazards. The first part introduces the underlying principles and techniques of the field, and the second examines case studies in terms of different risk as...

environmental risk assessment for veterinary antibiotics and hormone in malaysian agricultural soil

background: repeated applications of animal manure as fertilizer are normal agricultural practices in malaysia that may release veterinary antibiotics to environment from treated animals. methods: environmental risk assessment (era) on 5 commonly used antibiotics and one hormone in malaysian broiler farm was calculated using the ratio of measured environmental concentration (mec) and predicted ...
