Carbon tetrachloride (CCl4) is a synthetic chemical compound that has been widely used in various industrial and consumer applications since the early 20th century. Initially hailed for its effectiveness as a cleaning agent, fire extinguishing medium, and refrigerant, CCl4 was extensively employed in dry cleaning, metal degreasing, and the production of chlorofluorocarbons (CFCs). However, as scientific understanding of its environmental and health impacts grew, the perception of CCl4 shifted dramatically.

The hazards associated with CCl4 became increasingly apparent in the latter half of the 20th century. Research revealed its significant ozone-depleting potential, contributing to the thinning of the Earth's protective ozone layer. This discovery led to its inclusion in the Montreal Protocol, an international treaty designed to phase out substances that deplete the ozone layer. Consequently, the production and use of CCl4 for dispersive applications were largely discontinued in developed countries by the mid-1990s.

From a health perspective, CCl4 poses serious risks to human well-being. Exposure can occur through inhalation, ingestion, or skin contact, with the liver and kidneys being particularly vulnerable to its toxic effects. Acute exposure may lead to symptoms such as headaches, dizziness, and nausea, while chronic exposure has been linked to liver and kidney damage, and potentially, cancer. The International Agency for Research on Cancer (IARC) has classified CCl4 as possibly carcinogenic to humans (Group 2B).

Despite regulatory efforts to curtail its use, CCl4 remains a persistent environmental contaminant due to its long atmospheric lifetime and historical widespread use. It can be found in soil, groundwater, and air, particularly in areas with a history of industrial activity. The compound's ability to bioaccumulate in aquatic organisms further complicates its environmental impact, potentially affecting entire food chains.

The recognition of CCl4 hazards has spurred significant changes in industrial practices and consumer behavior. Alternative substances and technologies have been developed to replace CCl4 in many of its former applications.
