Credibility of Sources

Dihydrogen Monoxide is "Harmful"

Recently, our chemistry teacher has talked about determining which types of sources are reliable. In order to master this concept, he made us read this article claiming that there is a chemical, known as "dihydrogen monoxide", that can be very dangerous. According to this article, contact with this chemical can cause genetic mutations, affect protein cells, and damaging neurotransmitters, which is the main component of signals that are used in our nervous system. Due to this claim, this website recognizes dihydrogen monoxide as a carcinogenic substance, meaning that this chemical causes cancer. It is also claimed that one drop that we consume of this chemical could lead to immediate death. This substance or chemical can also cause tissue damage, soil erosion, and it was claim to be present in cancerous tumors as well. Also, this chemical was claimed to be used in nuclear power plants. It was claimed to be used as a bio terrorist weapon during World War II, and the article claims that it has been used by other terrorist organizations, including the al-Qaeda. This article tells us to watch for symptoms if we consume too much of this chemical. Symptoms include: excessive urination and sweating, vomiting, nausea, bloated feeling. Although this article says that dihydrogen monoxide is harmful; however, this chemical is the same thing as the chemical for water. In my point of view, this article is totally unreliable and built on lies. The reason as to why this is not factual is because of the fact that we consume a large amount of water everyday, yet we do not experience any of these symptoms stated in this article. We use water in our everyday lives, but we do not experience the detrimental health effects that are predicted by this article. Overall, this article is not a credible source. 

Dihydrogen monoxide, or water, is claimed by an unreliable article to be a "harmful" substance.
