microgram per litre
One microgram of dissolved substance in one litre of solution, a thousandth of a milligram per litre. It is the unit of trace analysis — heavy metals, pesticides, disinfection by-products and most things a drinking-water regulation sets a limit on well below the milligram range.
Watch out: Equal to one part per billion in water, with the same density proviso that applies to mg/L. At these levels the sampling and the handling usually contribute more error than the instrument does, so a µg/L result carries meaning only alongside the method that produced it.
