This manual describes the dynamic model TOXIWASP for simulating the transport and fate of toxic chemicals in water bodies. TOXIWASP combines the kinetic structure adapted from the Exposure Analysis Modeling System (EXAMS) with the transport framework provided by the Water Analysis Simulation Program (WASP), along with simple sediment balance algorithms. TOXIWASP formulates variable chemical degration rates from chemical characteristics of a compound and the environmental parameters of the aquatic system. These rates combine calculated first order rates due to several processes, including hydrolysis, biolysis, photolysis, oxidation, and volatilization. Sorption onto sediments and onto biomass is calculated assuming local equilibrium, using a chemical specific partition coefficient, and spatially varying environmental organic carbon fractions.
