Introduction The purpose of this paper is to analyze and discuss the impact of mercury poisoning on the occupational health of workers and its toxicology. As a result, the paper first elaborates the scientific details of the nature and effects of mercury, outlines the historical background of the problem in the workplace, identifies the sources of the problem, and assesses the gravity of the situation using a case study to see how mercury poisoning affects people at work. Also, this research examines the current status of mercury poisoning in workplaces, evaluates the impact of this toxic metal on the biosphere, conducts a succinct data analysis, endorses plans for the future along with proper suggestions, and draws a pertinent conclusion. The research primarily focuses on occupational health and attempts to identify and address the dangers associated with the physical exposure to mercury in some specific workplaces, while evaluating the possible solutions to the problem through the maintenance of a protected and healthy working atmosphere. Scientific Details of the Nature and Effects of Mercury Mercury, a heavy metal that is liquid in room temperature, is toxic in all its available forms – according to Olson (2016), even the slightest contamination from this element can cause gastrointestinal complications, neurological disorders, and fatal bilateral kidney malfunctioning. Olson (2016) further suggested that humans can get in touch with the metal in various ways, but the most common modes include breathing its vapor, absorbing it through the skin, or swallowing or infusing it by some means. The metal is available in nature as elemental mercury, inorganic salts, and some organic compounds; however, methyl mercury is frequently suggested to have the most dangerous impact on human health in the long run, as its absorption into the bloodstream can be fatal. Mercury is one of the constituent metals of the planet and is hardly found in nature in its elemental state; as a result, it appears as compounds or bivalent atoms, although the pure metal is conventionally used in manufacturing industries (for example, in certain types of electrical applications, fluorescent lamps, thermometers, barometers, and sphygmomanometers), exposing the workers to its toxicity. Even more dangerously, at normal temperatures, unwrapped mercury usually evaporates into extremely toxic odorless vapors causing grievous harm to the respiratory tract – as the temperature continues to increase; higher amounts of vapors are discharged, and this inflicts incurable sicknesses over the factory workers. Mercury is extracted from the ores of mercury sulfide, and traditionally, this is the key source for the commercial extraction of the metal through the treatment of the compound above 540º Celsius – consequently, laborers are exposed to pollution in two stages, firstly, by direct contact during extraction, and secondly, by inhalation of the metal during vaporization. World Health Organization (2017) reported that depending on the nature of the source, mercury poisoning could lead to a wide range of health issues, starting from metal disturbances to physical mutations. Workers exposed to the metal for longer-term can suffer from irreve
