Abstract

Air quality is an important issue worldwide due to the health implications on man and livestock. For this reason, different countries constructed the air quality index (AQI) which depicts pollution levels and the impact on health. PAQI is an example of an air quality index built by Plume Labs, Paris, France. It has seven levels (Low, Moderate, High, Very High, Excessive, Extreme, and Airpocalypse) of pollution which are linked to the World Health Organization (WHO) limits. This study aimed to assess the AQI of five different towns in Nigeria using the satellite model data released by Plumes Labs. Daily data of the towns were recorded between 9 am and 7 pm for 60 days and statistically analyzed. The air quality index was determined by whatever pollutant was measuring the highest. It was observed that PM2.5 and 03 (30 and 40 respectively) had the highest concentration levels most times. The results were compared with the PAQI indicator. The air quality of the towns has reached high levels of pollution above the maximum limit for 24 hours established by WHO.

Abstract

Plants had already long been utilized as medicines to treat illnesses. Theobroma cocoa is a plant with antifungal, antibacterial, antioxidant, antiemetic, larvicidal, hepatoprotective, anti-diarrheal, anti-inflammatory, antimalarial, anthelmintic, antiarthritic, wound healing, and anticarcinogenic potential. The purpose of this study was to look into the phytochemical compositions of crude extracts of Theobroma cocoa leaves and stem (bark) materials. Carbohydrates, saponins, and phlobatannins were found in higher concentrations in both the stem (bark) and the leaves, whereas tannins, glycosides, resins, and alkaloids were found in lower concentrations in both samples. Depending on the solvent used for extraction, different phytochemical compositions are obtained in each part of the tree. However, for the majority of the phytochemicals, water extraction yielded higher concentrations.
