Olayemi Arigbede is currently employed as an assistant lecturer in the Industrial Chemistry Programme, at Bowen University, Iwo, Nigeria. She has started her Ph.D. research on the use of castor seed oil as a base polyol material for synthesizing polyetheramides, polyesteramide, polyurethanes, and their modified forms for coating purposes. She is a member of the Chemical Society of Nigeria (CSN). Presently, she is the assistant secretary and 200 level student adviser of Industrial Chemistry Programme at Bowen University.

Research
Over the past five years, my research focus has been on human health risk to environmental contaminants through food and soil matrices. Discussed below are few of my research carried out.
Polycyclic aromatic hydrocarbons contamination in biscuit brands – Human exposure to PAHs compounds can happen through different pathways. The most prominent routes are through the ingestion of contaminated food. However, biscuits can be chemically contaminated with PAHs because of high baking temperature, duration of baking, and type of fuel used. Therefore, this study determines the concentrations of PAHs in selected biscuit brands randomly purchased from Nigerian markets. The health risk assessment of PAHs was also evaluated. The concentration of PAHs in ten brands of biscuits was determined using the Gas Chromatographic-Flame Ionization Detector (GC-FID). The results of this study also indicated that biscuit products were mainly contaminated with 6- and 4-ring PAHs, suggesting contamination from a fuel combustion energy source used in driving the processing of biscuits, baking, and heating. Therefore, there is a need for continuous monitoring and quality control checks of biscuit products by Health agencies.
Heavy metals contamination in biscuit products- As in the case of Nigeria as well as other developing countries, the daily food intake of children contains substantial proportion of biscuits which makes them more vulnerable to contamination because they have immature immune system and higher degrees of absorption. This food product is naturally enjoyed by school children and often times wrapped in attractive and colorful packs to attract them to buy the products. These packs sometimes contain toxic metals like Cr, Cu, Pb, Zn, and Ti which can contaminate the food on contact with the printed surface through blocking, peeling, rubbing, glazing and diffusion. However, it is required to continually track the quality of biscuit products that is being purchased by the consumer most especially children in order to ensure that the content of these contaminants do not go beyond the permissible level that will be detrimental to human health.
Currently, I am researching on the use of castor seed oil as a base polyol material for synthesizing polyetheramides, polyesteramide, polyurethanes, and their modified forms for coating purposes.
