61Water pollution — Raw sewage and industrial waste flows across international borders New River passes from Mexicali to Calexico, California. Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans and groundwater). Water p …
62Freshwater environmental quality parameters — are the natural and man made chemical, biological and microbiological characteristics of rivers, lakes and ground waters, the ways they are measured and the ways that they change. The values or concentrations attributed to such parameters can be… …
63Light pollution — This article is about light pollution in the visible spectrum. For information on pollution in the radio spectrum, see radio spectrum pollution. This time exposure photo of New York City at night shows skyglow, one form of light pollution …
64Eutrophication — The eutrophication of the Potomac River is evident from its bright green water, caused by a dense bloom of cyanobacteria. Eutrophication (Greek: eutrophia healthy, adequate nutrition, development; German: Eutrophie) or more precisely… …

67Samarium-151 — SimpleNuclide|Samarium|151 is a radioisotope of samarium with a half life of 90 years, undergoing low energy beta decay, and has a fission product yield of 0.4203% for thermal neutrons and U 235, about 39% of Sm 149 s yield. The yield is somewhat …
68ion-exchange reaction — ▪ chemical reaction Introduction any of a class of chemical reactions between two substances (each consisting of positively and negatively charged species called ions (ion)) that involves an exchange of one or more ionic components.… …
69Peter Armbruster — (born July 25 1931 in Dachau, Bavaria) is a physicist at the Gesellschaft für Schwerionenforschung (GSI) facility in Darmstadt, Germany, and is credited with discovering elements 108 Hassium, 109 Meitnerium, 110 (darmstadtium), 111 (roentgenium) …
70Tin-121m — is a radioisotope and nuclear isomer of tin with a halflife of 43.9 years. In a normal thermal reactor, it has a very low fission product yield; thus, this isotope is not a significant contributor to nuclear waste.Fast fission or fission of some… …
