The primary aim of this capstone paper was to review and examine previous works of literature on the effects of ototoxic organic solvents and various heavy metals on the auditory structure due to occupational exposure. Additionally, the research also focused on identifying work environments, which are characterized by such ototoxic toxins. The method for picking organic solvents and heavy metals encompassed the existing data that signified that such chemical substances could induce auditory challenges among workers in divergent work settings. Furthermore, the ambiguities of the publications were also extensively considered before they could be incorporated in this research. References to occupational ototoxicity were celebrated for organic solvents like styrene, toluene, carbon disulfide, trichloroethylene, and arsenic compounds. The references for heavy metals such as mercury and lead were also noted.

Consequently, the publications were able to show that these substances induce extensive damage to the auditory system, especially for those who experience prolonged occupational exposure. It was also noticed that occupational exposure to hazardous noise plays a critical role in work-related hearing loss, especially when combined with these substances. The gad in literature was also identified since it is challenging to examine the ototoxic effects of individual chemicals since work environments are characterized by numerous substances that contribute significantly to auditory challenges like deafness and tinnitus.
