The Google Ngram Viewer chart displays the frequency of the term chemical risk in books from 1900 to 2019. The graph shows that the term was virtually nonexistent before 1960 but began to rise steadily in the 1970s. This increase aligns with growing environmental awareness, industrial safety concerns, and regulatory developments, such as the formation of the U.S. Environmental Protection Agency (EPA) in 1970. The peak in the 1990s suggests heightened discourse on chemical hazards, possibly due to high-profile incidents and stricter regulations. After some fluctuations in the 2000s and 2010s, the term's usage slightly declines, indicating evolving language or shifts in focus.[1]
