Abstract
The influence of biodegradation by the microscopic fungus Aspergillus niger on the diffusion desorption of a dialkylphthalate plasticiser from PVC was studied. It is shown that the loss of dialkylphthalate accelerates with bi n-overgrowth on the PVC. Loss of plasticiser is limited by its diffusion in the material volume in the case of bio-overgrowth, whereas loss from the s ame polymer in the absence of bio-overgrowth is evaporation limited.
