delova u jedan bilion (ppt) Explanation: Ovi rezultati su stimulisali američke istraživače da pregledaju vode koje teku u jezero Mid (Lake Mead) u Nevadi i Arizoni, gde su pronašli jedan sličan koktel, zajedno sa ženskim hormonom estradiolom - sa nivoom većim od 20 ppt (delova u jedan bilion) koji prema izveštaju u časopisu “Science News” predstavlja “koncentraciju koja može izazvati da neki mužjaci riba proizvedu protein za stvaranje jaja, koji se normalno može naći samo kod ženki riba koje su reproduktivno aktivne” http://www.cps.org.rs/Buducnost/buduc07.htm In science and engineering, the parts-per notation is a set of pseudo units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement. This is a way of expressing very dilute concentrations of substances. Just as per cent means out of a hundred, so parts per million or ppm means out of a million. Usually describes the concentration of something in water or soil. One ppm is equivalent to 1 milligram of something per liter of water (mg/l) or 1 milligram of something per kilogram soil (mg/kg). Mi koristimo dugu skalu SI prefiksa, pa je engleski trilion kod nas bilion. |

на нивоу делова по билиону/на нивоу ppb Explanation: Ostaci su detektovani na nivou ppb i ispod nivoa toksičnosti. http://scindeks.ceon.rs/article.aspx?query=ISSID&and&4093&pa... http://facta.junis.ni.ac.rs/phat/phat2001/phat200106.html Може и ''на ppb нивоу''. С` тим што ми није јасно ово ON ppt level, пошто је правилно AT THE ppt level. |
