Mathematical Models in Ecochemistry
نویسنده
چکیده
General concepts concerning models, their logical and analogical status, are briefly outlined. The use of compartmental models to simulate the kinetics of compounds in the environment is illustrated by a discussion of carbon dioxide in the atmosphere and oceans and its uptake by plants. The application of compartmental models to the kinetics of organochlorine compounds in vertebrates and in ecosystems is reviewed and the simplifying assumptions are made explicit. It appears from the evidence available, and assuming the compartmental models are valid simulations of ecosystems, that there may be significant mechanisms of removal of organochiorine insecticides from the biosphere, possibly by chemical degradation in the troposphere or stratosphere; these mechanisms require detailed investigation to assess their importance.
