Abstract

Humans' indiscriminate usage of heavy metals has a negative impact on the world's natural
ecosystem. One of the main causes of contaminating the fresh and healthy atmosphere in rural
Pakistan is the use of coal and soil in an improper manner by brick kilns. Different heavy metal
concentrations and their impact on the surrounding areas of Pakistan's District Lakki Marwat were
investigated in this study. Acid digestion methods were used to prepare samples, which were then
examined using an Atomic Absorption Spectrophotometer. The concentrations of cadmium, iron,
and lead in certain samples exceeded the WHO's permitted level, whereas nickel and zinc
concentrations were within the limit. It was also discovered that the supply of raw materials is the
key determinant in the buildup of heavy metals in the areas near brick not the age of the kiln.
