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 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.
