C44 TOXIC SORPTION OPTION, DIFFUSION AND MIXING
*
* NTOXN: TOXIC CONTAMINANT NUMBER ID (1 LINE OF DATA BY DEFAULT)
* ISTOC: 0 INORGANIC SOLIDS BASED PARTITIONING ONLY (Kd APPROACH)
* 1 FOR DISS AND PART ORGANIC CARBON SORPTION, POC IS SPECIFIED
* 2 FOR DISS ORGANIC CARBON SORPTION AND POC FRACTIONALLY
* DISTRIBUTED TO INORGANIC SEDIMENT CLASSES
* 3 FOR NO DISS ORGANIC CARBON SORPTION AND POC FRACTIONALLY
* DISTRIBUTED TO INORGANIC SEDIMENT CLASSES
* DIFTOX: DIFFUSION COEFF FOR TOXICANT IN SED BED PORE WATER (M^2/s)
* DIFTOXS: DIFFUSION COEFF FOR TOXICANT BETWEEN WATER COLUMN AND
* PORE WATER IN TOP LAYER OF THE BED(M^2/s)
* > 0.0 INTERPRET AS DIFFUSION COEFFICIENT (M^2/s)
* < 0.0 INTERPRET AS FLUX VELOCITY (m/s)
* PDIFTOX: PARTICLE MIXING DIFFUSION COEFF FOR TOXICANT IN SED BED (M^2/s)
* (if negative use zonal files PARTMIX.INP and PMXMAP.INP)
* DPDIFTOX: DEPTH IN BED OVER WHICH PARTICLE MIXING IS ACTIVE (m)
