Modeling transport of fluoride in soil under field condition Elham Chavoshi E mail address chavoshie@yahoo com 30 January 2011 Department of Soil Science Isfahan University of Technology Isfahan 84156 83111 Iran Supervisor Majid Afyuni Email address afyuni@cc iut ac ir Supervisor Mohammad Ali Hajabbasi Email address hajabbas@cc iut ac ir Advisor Hossein Khademi Advisor Amir Hossein Khoshgoftarmanesh Advisor Karim Abbaspour Department Graduated Program Coordinator Farshid Nourbakhsh Department of Soil Science Collage of Agriculture Isfahan University of Technology Isfahan Iran Abstract The purpose of this study was to determine distribution of fluoride F content in surface soil of Isfahan province The fluoride adsorption desorption and movement in a calcareous soil and the cumulative daily F intake and health risk assessment were another parts of this study In the third part of the study spinach and alfalfa was planted in lysimeters with three replications To evaluate F content in surface soil part 1 257 topsoil samples in an area of 6800 km2 in Isfahan province were collected The average of total F content 106 7 mg kg 1 and soluble F content 0 88 mg L 1 were respectively lower and greater than the world s average Maximum sorption capacity qmax of F calculated from Langmuir model was 0 4 mg g 1 for calcareous soils For part 3 the treatments included two concentrations of F and bromide Br that were added to the soil surface as sodium fluoride and potassium bromide salts respectively Hydrus 1D program was employed to model the movement of F in the soil The highest concentrations of total F and water soluble F were observed in the surface soil layer The maximum of EDI estimates for cereals vegetables and water exposure routes were 36 and 29 4 g kg 1 day 1 for children and adults respectively in the last study Keywords fluoride kriging HYDRUS 1D hazard quotient
