| Abstract | ||
| Industrial chemicals have driven major technological progress, yet their mismanagement has repeatedly resulted in catastrophic human exposure. This paper presents a comparative analysis of three landmark chemical disasters: methylmercury poisoning in Minamata and Niigata (Japan), the 1971–1972 mercury-treated wheat poisoning in Iraq, and the 1984 methyl isocyanate release in Bhopal (India). Despite involving different chemicals, exposure routes, and timescales, these events reveal a common pattern of systemic failure, including ignored early warning signs, ineffective hazard communication, degraded safety systems, weak regulatory oversight, and inadequate medical preparedness. The study contrasts chronic dietary exposure, acute ingestion, and hyperacute inhalation pathways, demonstrating how chemical properties and toxicokinetics govern health outcomes while systemic vulnerabilities determine disaster magnitude. Building on these historical lessons, the paper extends its analysis to the petroleum and natural gas sector, emphasizing mercury occurrence, speciation, and removal as a persistent but under-recognized process safety and environmental hazard. The findings highlight that chemical disasters arise not from chemistry alone, but from unprepared systems. Effective prevention requires integrated risk governance, robust safety culture, accurate chemical knowledge, and consistent global safety standards.o | ||
