“…The uptake of a mixture of PAHs from insoluble dietary fiber such as carboxymethyl cellulose, agar and young barley leaves were studied using artificial gastric and intestinal juices. These studies revealed that young barley leaves had a high sorption capacity for PAHs compared to carboxymethyl cellulose and agar both in artificial gastric and intestinal juices [21]. Similar results were obtained by Viau et al [22] in Sprague-Dawley rats.…”

“…Stavric and Klassen [20] reported that foods rich in fat and fiber reduce the uptake of BaP. Dietary fiber has been reported to affect the bioaccessibility of BaP, as it absorbs BaP [21]. The uptake of a mixture of PAHs from insoluble dietary fiber such as carboxymethyl cellulose, agar and young barley leaves were studied using artificial gastric and intestinal juices.…”

Introduction Bioaccessibility is a growing area of research in the field of risk assessment. As polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants, they are the toxicants of focus to establish cancer risks in humans. Orally ingested PAHs also cause toxicity and even affect the pharmacokinetic behavior of some therapeutic agents. Toward this end, bioaccessibility is being used as a tool to assess the risk of PAHs via dietary exposures. Areas covered This review covers some in vitro bioaccessibility models for PAHs that have been used for the past one-and-a-half decade. This review also considers the factors that influence bioaccessibility and debates the merits and limitations of using a bioaccessibility concept for estimating risk from ingestion of PAH-contaminated soil and food. Finally, the authors discuss the implications of bioaccessibility for PAH-induced toxicity and cancers in the context of risk assessment. Expert opinion So far, much of the focus on PAH bioaccessibility is centered on soil as a preferential matrix. However, ingestion of PAHs through diet far exceeds the amount accidentally ingested through soil. Therefore, bioaccessibility could be exploited as a tool to assess the relative risk of various dietary ingredients tainted with PAHs. While bioaccessibility is a promising approach for assessing PAH risk arising from various types of contaminated soils, none of the models proposed appears to be valid. Bioaccessibility values, derived from in vitro studies, still require validation from in vivo studies.

“…Boki et al. (2007) found that CMC could firmly bind with PAHs in artificial gastric juice and intestinal juice, while the bioaccessibility of PAH bound by other celluloses and chitosan needs to be further investigated. One solution to bypass this health issue is to employ easy‐to‐peel cellulose‐ and chitosan‐based edible coatings, similar to peelable sausage casings, thus avoiding consuming the coating‐bound PAHs.…”

Excessive oil uptake and formation of carcinogens, such as acrylamide (AA), heterocyclic amines (HCAs), and polycyclic aromatic hydrocarbons (PAHs), during deep‐frying are a potential threat for food quality and safety. Cellulose‐ and chitosan‐based edible coatings have been widely applied to deep‐fried foods for reduction of oil uptake because of their barrier property to limit oil ingress, and their apparent inhibition of AA formation. Cellulose‐ and chitosan‐based edible coatings have low negative impacts on sensory attributes of fried foods and are low cost, nontoxic, and nonallergenic. They also show great potential for reducing HCAs and PAHs in fried foods. The incorporation of nanoparticles improves mechanical and barrier properties of cellulose and chitosan coatings, which may also contribute to reducing carcinogens derived from deep‐frying. Considering the potential for positive health outcomes, cellulose‐ and chitosan‐based edible coatings could be a valuable method for the food industry to improve the quality and safety of deep‐fried foods.

“…Naphthalene is a natural constituent of coal tar (approximately 11%). It is present in gasoline and diesel fuels and it is produced when these fuels are burnt and when tobacco or wood is burnt [4,5]. The adsorption of polycyclic hydrocarbon or hydrophobic compound by sediments and soil is positively correlated with their organic matter content [6].…”

Polycyclic aromatic hydrocarbons occur naturally in petroleum oil and coal and the burning of fuel and the activities of paper mills also release these compounds to the environment. Batch experimental adsorption study for both soil fractions was conducted in a soil slurry system at ambient temperature, using <0.02mm particle sizes. Comparison was made of the linear least-squares method and a trial-and-error nonlinear method of some widely used isotherm models for the adsorption of naphthalene on clay and silt fractions. The experimental results were fitted to the Langmuir, Freundlich, Radke-Prausnitz, Sips, Temkin and Redlich-Peterson isotherms to obtain their characteristic parameters of each model. The coefficient of determination obtained from the different models using the linear method showed that Freundlich isotherm had the highest values for both clay and silt soil fractions with values of 0.843 and 0.897 respectively. The equilibrium data did not fit the Langmuir isotherm with values of 0.287 and 0.021 for clay and silt soil respectively. Using the nonlinear method the equilibrium data gave good fit for Radke-Prausnitz, Sips, Temkin and Redlich-Peterson isotherms. Sips isotherm gave the best fit for silt soil with the r2value of 0.9779 and this was followed by Temkin isotherm for clay soil with the value of 0.9673.
