Abstract
The objective of this study was to determine health risks associated with consumption of cabbage and lettuce sampled in an urban industrialized study area. Samples were initially digested in Teflon vessels using HNO3 and H2O2, homogenized in Na2SO4, agitated in a mixture of hexane/acetone, cleaned-up and analyzed in ICP - MS in order to quantify toxic heavy metals. The PAH content was also quantified in GC-MS against reference PAH congeners.
Highlights
Many health-conscious consumers are increasingly making deliberate choices for plant-based diets because probably they think they were safer
The results revealed that females (51.23%) consume relatively greater portions of the selected samples than males
The results were not consistent with a previous study conducted in the study area which concluded that males consumed relatively more of the selected samples [31]
Summary
Many health-conscious consumers are increasingly making deliberate choices for plant-based diets because probably they think they were safer. Majority of these consumers who dwell in cities demand leafy vegetables for their daily consumption. Urbanization is associated with industrialization, and with it comes the attendant anthropogenic hazards. These activities contaminate the soil with toxic heavy metals such as arsenic (As), cadmium (Cd), mercury (Hg) and lead (Pb) [1,2].
