Contamination

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. All chemicals contain some level of contamination. Contamination may be recognized or not and may become an issue if the contaminated chemical is mixed with other chemicals or mixtures and causes additional chemical reactions. The additional chemical reactions can sometimes be beneficial, in which case the label 'contaminant' is replaced with reactant or catalyst. If the additional reactions are detrimental, other terms are often applied such as toxin, poison or pollutant depending on the chemistry involved. A major fraction of chemistry is involved with identifying, isolating, and studying contaminants.contaminatiion is bad for our planet just like the oil spill.
