Did you know that nitrites in drinking water can permenantly damage or even kill infants? Read our full overview further below.
High levels of nitrates in drinking water pose a threat especially for young human infants because humans and other animals usually have a bacteria that converts nitrates into nitrites within the large intestines.While adults are protected from the harmful effects of these bacteria[since the digestive system of human adults is highly acidic], the stomach of an infant being very low in acidity , lets the bacteria move up in the stomach where nitrates are subsequently converted into nitrites.This is a serious issue as nitrites pose a serious threats to creatures which contain hemogobin[ such as humans] in their blood as nitrites can attach themselves to the hemogobin in the blood of infants .As a result of this attachment, the infant’s body is unable to receive a proper supply of oxygen to its tissues.Significant permenant damage can result.
Remember, that we welcome your Science Fact of the Month. Feel free to send it to us at email@example.com All submissions should include a fact with atleast a couple of sentences which provide supporting details on the fact. Including a reference is encouraged.
Did you know that the addition of nutrients to an ecosystem can be quite deadly?
An excess of nutrients in fertlizer rerun off from farms can cause a signifcant growth of algae causing an algal bloom.Eventually these algae will die and decomposing bacteria, will, in turn break down the algae .Unfortunately, the decomposing bacteria requires a lot of oxygen to do this.Since they are depleting the levels of oxygen , fish and other aquatic `creatures begin to die .Not only can severe ecological damage occur, but also the decline in fisheries can cause a negative effect on the economy.
See you next month for more Science.
