Abstract

Concentrations of 16 priority polycyclic Aromatic Hydrocarbons (PAHs) were determined in 30 brands of Nigerian and imported pastas in Nigerian market. The pasta samples were categorised into (1) noodles (2) spaghetti and (3) macaroni.

Analysis were performed by GC MS after soxhlet extraction of the sample and clean up of the extract. The concentration of Σ16 PAHs in both the Nigerian and imported brands are in the range of 009 to 0.8 mgkg-1 and 0.002 to 0.007 mgkg-1 respectively.

The Bap concentrations in 75% of the Nigerian samples were less than 0.001mgkg-1 permissible limit specified for processed cereal based food while all the brands of imported samples were below the maximum limit.

The concentrations of Σ8 carcinogenic PAHs in both the Nigerian and imported brands ranged from 0.001 to 0.01 mgkg-1 and 0.001 to 0.004 mgkg-1 respectively.

The Margin of Exposure based on PAH8 as an indicator for the occurrence and effects of PAHs in food for generally exposed individuals were less than 10,000 in 25% and 0% for child and Adult scenarios respectively for Nigerian brands.

Introduction

The introduction and distribution of man-made compounds or excessive amount of natural compounds have created avenue to understanding the effects of polycyclic aromatic hydrocarbons on humans and the environment. It is therefore, necessary to study the effects on individuals to population, communities and environments.

The contamination of food by chemical hazards is a worldwide public health concern. Among organic contaminants, polycyclic aromatic hydrocarbons (PAHs) represent an important class of food contaminants.1

Food can be contaminated from environmental source, industrial food processing and certain home food preparation.2 4 Humans are exposed to PAHs by various pathways.

For non- smokers, the major route of exposure is consumption of food and it contributes to more than 90% of total PAHs exposures of the general pollution in various countries.5 7

Food contamination may also occur during periods of atmospheric pollution in which PAHs are deposited on seeds, fruits or vegetables, which are then consumed.7 9
