Abstract

Health and welfare of population are priority reasons to study the toxic effects of chemical pollutants. These effects can directly produce deterioration of health or can cause less healthful environment toxicity and restricting food production. Thereby, preventing such a consequence is important for human health risk assessment. In recent times, the use of recycled materials for packaging has undeniably been intensified. Nevertheless, recycling systems could not effectively eliminate the potential effect of chemical pollutants (alkyl phenol, phthalates, aldehydes, etc.) existent in such packages. The migration process and/or the ability of these pollutants to be absorbed into the recycled material, subsequently released by the packaging material, and then trapped by the matrices they contain, has become a potential source of exposure to consumers. This process is controlled by the nature of the packaging, time, temperature, and the physicochemical properties of the contaminant. The literature suffers from a lack of data related to the physicochemical (aqueous solubility, vapor pressure, Henry’s constant, etc...) of these contaminants. In this work, we are going to describe the experimental devices used for aqueous solubility, vapor pressure and octanol/water partition coefficient determination.

Summary

Introduction

Industrial and technology fields use hundreds of chemicals within the production process wherever large amounts of those contaminated chemicals escape or are non-intentionally introduced into the surroundings. In the area of food contact materials (FCM), there are different interaction mechanisms which could potentially affect the integrity of the food and/or polymer These mechanisms can be divided into permeation, sorption and migration. Chemical pollutants represent difficulties for the experimental calculation of their properties, for low aqueous solubility (mole fraction lower than 10-4), a low vapor pressure (less than 10-2 Pa), and a high lipophilicity (log Ko/w beyond 3). With this aim, we studied the temperature dependence of the aqueous solubility of dipentylphthalate [298.15-303.15 k] using “generator column-on-line solid phase extraction method” [3]. The shake-flask method for octanol-water partition of heavy organic compounds, having log Ko/w >4, is validated by studying the anthracene at 298.15 K
