Abstract EN

This research paper aims to unveil one of the negative effects of environmental pollution that is not visible to the eye, which is the impact of polluting gases on our fixed material wealth, the other is suffering from what cars and factories produce, such as the suffering of human lung, especially with the long period of his birth, and the weakness of his building materials, And after conducting field inspection and chemical analyzes of two samples from the remains of the defensive walls of the city of Hanin and Mansoura Al-Mariniya in Tlemcen., it was found that the gases resulting from pollution pose an imminent danger to the archaeological monuments and the remains of archaeological sites, through the physicochemical damage that resulted from the change in the chemical and physical composition of building materials, after the gases coalesced with rain water, which becomes acidic.

It penetrates into the archaeological landmark, which leads, after a period of time, to the disappearance of a circle of civilizational communication With his influence in building materials, he led, after a period of time, to the deletion of a circle of civilized communication, which was no longer just pieces and nothing more seen for the purpose of self-entertainment, but rather became a raw material for scientific research and the tourism industry.
