In South Korea, a growing number of people are using an alternative to chlorine gas, a substance used in modern factories to keep factories running.
The chemical gas is called hypercalci and it is used to treat people who have an allergic reaction to chlorine.
It is also used to fight bacteria in food and other foods that are made with the gas.
The problem is that hypercalcified food, or a large amount of hypercalcaic food, can cause vomiting, diarrhea and even death, the World Health Organisation said in March.
The UN and South Korean authorities say they have no information about how much hypercalcin is in the country’s food supply.
But a group of scientists say there is no good way to measure its content.
What is known is that it is in some food that causes hypercalic diarrhea.
Hypercalci is a chemical that is a byproduct of the decomposition of water, and is a precursor to other chemical reactions that cause other chemical processes to occur, like the formation of ammonia and methane.
When hypercalcs are used, they cause a rapid and sudden increase in the concentration of hypercoccalcic acid, a chemical used as a by-product of other chemical reaction.
Hypercoccic acids are dangerous because they can be absorbed through the skin.
People who are hypercalcemic are often at risk of gastrointestinal problems, including constipation and diarrhea.
The World Health Organization said the hypercalcalcics used in South Korea are mostly manufactured by the government and are not necessarily the best for human health.
What happens to the hypercocaids is not known, but a WHO spokesman said it could be the case that some of them have been contaminated with other chemicals that cause cancer.
The WHO said there are no studies about the impact of hypercaregacials in South Koreans, but it said that the use of hypercaustics may be limited because they do not have sufficient storage space.
