The Chemical Safety Board of India has announced that it has designated chemical sensitivity as a condition under the Toxic Substances Control Act.
The board’s report, published in the Journal of the American Medical Association, stated that “a chemical reaction is classified as chemical sensitivity if the reactants are known to be highly toxic to humans, animals or plants and the toxic effects are irreversible.”
The report noted that “there is evidence to indicate that there are many toxicants which have been identified as chemicals with a chemical sensitivity, although it is not clear whether these are the most toxic of the chemicals with chemical sensitivity.”
The board also stated that the classification of chemical sensitivity “is not intended to limit or exclude the use of other potentially hazardous chemicals that are already in use.”
The chemical board’s classification of the chemical reaction as chemical vulnerability is similar to that of the World Health Organization, which states that “in the context of a chemical vulnerability, the toxicity of a given chemical is determined by the toxicity level and potential risk to human health.
For example, a chemical may be classified as a chemical toxicity level that is very low but very high when it comes to the toxicity potential of the individual component(s).”
The chemical safety board’s definition of chemical vulnerability does not include the use by a person of a toxic compound in a way that would harm the health of others.
The chemical health board’s decision is part of a larger debate over the potential for a toxicological classification that could impact the safety of people, and is expected to have broad political ramifications.
“This is a huge change and a very significant development,” said Michael J. Johnson, a professor at the University of Pittsburgh School of Medicine who studies chemical toxicity.
“It makes it much more difficult for us to determine the toxicity risks of certain chemicals.”
A chemical toxicology classification is also likely to increase the complexity of testing for chemicals, and increase the cost of toxicology testing, which could cost tens of thousands of dollars per case, Johnson said.
In the U.S., the Environmental Protection Agency has said that the current classification system for chemical hazards is “not sufficient,” and the agency has recommended that the chemical board require a more comprehensive classification system that is more comparable to the World Heath Organization’s standard.
A spokesperson for the National Institutes of Health did not respond to a request for comment about the chemical health panel’s decision.
While the Chemical Safety Review Board’s decision does not apply to most chemicals, the chemical toxicologists who were involved in the process for the chemical safety review say that the decision could affect their work.
“In my opinion, the classification has an impact on our work because it is a very comprehensive approach,” said Dr. K.G. Gupta, a toxicologist with the UPMC School of Public Health.
“There is no single toxicology classifier that would accurately assess the toxicity risk for any given chemical.
I would be hesitant to assign a toxicity risk to a particular chemical because the risk might change over time.”
Gupta told New Scientist that he was concerned that a classification of “chemical vulnerability” could have a negative impact on the toxicology research conducted by toxicologists.
Gupta and others also argue that it is the lack of clarity around what is meant by “chemical sensitivity” that has led to confusion and misinformation.
“We are trying to use this very broadly and broadly in terms of toxicity,” Gupta said.
“I don’t think we understand what it means.
And if we are not clear, I would not be able to use our data for toxicology.”
For example: The chemical toxicologist who worked on the chemical sensitivity classification of Bismuth in India, V.S. Pratap, told New Sciur that he “would be very hesitant” to assign chemical vulnerability to Bismoth, because it was a “new chemical” that was not previously known to cause cancer.
“The toxicity of Bismauth was very high,” Pratopathy said.
When asked if he was aware that Bismaoth was toxic, Pratoped said, “I have no idea.”
Gupta, who is also the co-founder and director of the Center for Biological Diversity’s Global Network on Chemical Toxicology, said that when he was first introduced to the concept of chemical toxicologies in the early 1990s, the word “toxicology” did not have a specific meaning for him.
“What I remember from the ’90s is the idea of toxicos and toxicosophists and the concept that chemicals can cause harm,” Gupta told the New Scientist.
“At that time, I had not heard of toxicosis or toxicosophy and toxicosis was not part of the vocabulary.
So when I saw that word, I said to myself, ‘OK, this sounds pretty cool.
Gupta said that he first started using the term toxicology to describe the toxicological classifications of Bismo and Bismut to explain to his colleagues that the toxic
