ABSTRACT

Phthalate esters (PAEs) are widely used in plastic consumer products and many studies published to date have associated these chemicals with severe human health problems. Particularly, the risks within warehouses, which involve large quantities of PAE sources stored in closed spaces, have not been addressed. This article presents an integrated inventory control model to determine the periods within the supply cycle where concentrations of PAEs are likely to represent a risk for the warehouse personnel. This model considers the dynamic aspect of the warehouse supply and consumption mechanisms, and links it to the release patterns of PAEs in closed environments which depend on the type of materials, temperature and time. Numerical analysis corroborates that, in certain periods of time, concentrations of PAEs in the warehouse can exceed permissible levels for humans, and thus the use of appropriate protective wear and decontamination procedures should be established.
