    (University of North Bengal, 2023) Nayab, Naira; Md Anzer Alam
    Automobile transportation has been strongly associated with air pollution throughout various stages, like driving, fueling, production, and disposal.

This study aimed to explore the harmful effects of vehicle emissions on the physical structure and anatomy of Mango trees in the Samastipur district of Bihar, India.
