Chemophobia is an aversion to or prejudice against chemicals or chemistry. The phenomenon has been ascribed both to a reasonable concern over the potential adverse effects of synthetic chemicals, and to an irrational fear of these substances because of misconceptions about their potential for harm, particularly the possibility of certain exposures to some synthetic chemicals elevating an individual's risk of cancer. Consumer products with labels such as "natural" and "chemical-free" appeal to chemophobic sentiments by offering consumers what appears to be a safer alternative.
Definition and uses
There are differing opinions on the proper usage of the wordchemophobia. The International Union of Pure and Applied Chemistry defines chemophobia as an "irrational fear of chemicals". According to the American Council on Science and Health, chemophobia is a fear of synthetic substances arising from "scare stories" and exaggerated claims about their dangers prevalent in the media. Despite containing the suffix -phobia, the majority of written work focusing on addressing chemophobia describes it as a non-clinical aversion or prejudice, and not as a phobia in the standard medical definition. Chemophobia is generally addressed by chemical education and public outreach despite the fact that much chemophobia is economic or political in nature. Michelle Francl has written: "We are a chemophobic culture. Chemical has become a synonym for something artificial, adulterated, hazardous, or toxic." She characterizes chemophobia as "more like color blindness than a true phobia" because chemophobics are "blind" to most of the chemicals that they encounter: every substance in the universe is a chemical. Francl proposes that such misconceptions are not innocuous, as demonstrated in one case by local statutes opposing the fluoridation of public water despite documented cases of tooth loss and nutritional deficit. In terms of risk perception, naturally occurring chemicals feel safer than synthetic ones to most people. Consequently, people fear man-made or "unnatural" chemicals, while accepting natural chemicals that are known to be dangerous or poisonous. The Carcinogenic Potency Project, which is a part of the US EPA's Distributed Structure-Searchable Toxicity Database Network, has been systemically testing the carcinogenicity of chemicals, both natural and synthetic, and building a publicly available database of the results since the 1980s. Their work attempts to fill in the gaps in our scientific knowledge of the carcinogenicity of all chemicals, both natural and synthetic, as the scientists conducting the Project described in the journal, Science, in 1992: In 2020 European UnionChemicals — Strategy for Sustainability has been described as a textbook example of pseudo-scientific and chemophobic regulation by David Zaruk, as it contains numerous references to "toxic-free environment", refers to equally controversial precautionary principle and refers to a pseudo-scientific article on Environmental Health News as reference for alleged link between endocrine disruptors and COVID-19 pandemics.
Causes and effects
Chemistry professor writes that historically chemists have experienced chemophobia from the population at large, and considers that it is rooted both in irrational notions and in genuine concerns. Professor Gordon Gribble has written that the start of chemophobia could arguably be attributed to Silent Spring, and that subsequent events such as the contamination of Times Beach and the disaster at Bhopal, India only exacerbated the situation. These events have led to association between the word "chemical" and notions of things that unnatural or artificial and also dangerous, and the opposite has occurred, where goods are marketed as "chemical free" or "natural", to avoid this association, which in turn reinforces the misconception that "chemicals" are unnatural and dangerous. The chemical industry has moved to make chemicals used as flavoring or aromas using biotechnology instead of synthetic chemistry, as the products can be marketed as "natural". According to the industry advocacy group American Council on Science and Health, chemophobia is a growing phenomenon among the American public and has reached "epidemic" proportions among the general public. In a book published by the Council, Jon Entine writes that this is in part due to the propensity of people to show alarm at the reported presence of chemicals in their body, or in the environment, even when the chemicals are present in "minuscule amounts" which are in fact safe. Elsewhere, Entine has argued that chemophobia is linked to a precautionary principle in agricultural policy, which could jeopardize the world's ability to feed its ever-expanding population. In the United Kingdom, Sense About Science produced a leaflet aimed at educating celebrities about science, in which it said that humans carry only small amounts of "chemical baggage" and that it is only because of advances in analytical chemistry that we can detect these traces at all. Philip Abelson has argued that the practice of administering huge doses of substances to animals in laboratory experiments, when testing for carcinogenic potential, has led to public chemophobia by raising unjustified fears over those substances' effect on humans. He sees an opportunity cost in the "phantom hazards" such testing conjures, as it distracts from attention on known hazards posed to human health.
