“…Filtration of the air is one method of cleaning the air that has proven to be both popular and successful [ 58 ]. Particulate matter (PM) comprises tiny particles or liquid droplets that are so tiny that they can be inhaled and cause significant harm to an individual’s health [ 59 ]. PM, metals, black carbon, nitrate, organic aerosols, polycyclic aromatic hydrocarbons, automotive exhaust, and sulfates comprise microscopic particles and liquid droplets floating in the air [ 60 ].…”

Autophagy is an evolutionarily conserved cellular system crucial for cellular homeostasis that protects cells from a broad range of internal and extracellular stresses. Autophagy decreases metabolic load and toxicity by removing damaged cellular components. Environmental contaminants, particularly industrial substances, can influence autophagic flux by enhancing it as a protective response, preventing it, or converting its protective function into a pro-cell death mechanism. Environmental toxic materials are also notorious for their tendency to bioaccumulate and induce pathophysiological vulnerability. Many environmental pollutants have been found to influence stress which increases autophagy. Increasing autophagy was recently shown to improve stress resistance and reduce genetic damage. Moreover, suppressing autophagy or depleting its resources either increases or decreases toxicity, depending on the circumstances. The essential process of selective autophagy is utilized by mammalian cells in order to eliminate particulate matter, nanoparticles, toxic metals, and smoke exposure without inflicting damage on cytosolic components. Moreover, cigarette smoke and aging are the chief causes of chronic obstructive pulmonary disease (COPD)-emphysema; however, the disease’s molecular mechanism is poorly known. Therefore, understanding the impacts of environmental exposure via autophagy offers new approaches for risk assessment, protection, and preventative actions which will counter the harmful effects of environmental contaminants on human and animal health.

The activities of artisans conducted regularly in automobile workshops had been observed to generate pollutants that are not limited to particulate matter (PM), Polycyclic Aromatic Hydrocarbons (PAHs). Thus, this research provided data on the quantification of PAHs coupled with the building of a predictive statistical model for the prediction of benzo[a]pyrene (BaP) in Benin City. The City was divided into four zones, namely North West (NW), North East (NE), South East (SE) and South West (SW) and a total of 180 representative samples were collected from artisans' workshops in both wet and dry seasons using Apex2IS Casella standard pump fitted with conical inhalable sampling (CIS) head at a flow rate of 3.5L/min for 8 hours. Meteorological parameters were collected simultaneously with the PM2.5. PAHs were extracted and quantified using GC-FID. The annual average concentration of the total PAHs bounded to PM2.5 for NW, NE,
