The total solids in urine are on average 59 g (2.1 oz) per day per person. [8] Urea is the largest constituent of the solids, constituting more than 50% of the total. The daily volume and composition of urine varies per person based on the amount of physical exertion, environmental conditions, as well as water, salt, and protein intakes. [6]

Concentrations of heavy metals such as lead, mercury, and cadmium, commonly found in sewage sludge, are much lower in urine.

It is often, though not necessarily, associated with urinary incontinence and polyuria (large total volume of urine). However, in other cases, urinary frequency involves only normal volumes of urine overall. [3] [citation ...
After a decade of near-zero growth in methane levels, "globally averaged atmospheric methane increased by [approximately] 7 nmol/mol per year during 2007 and 2008. During the first half of 2009, globally averaged atmospheric CH 4 was [approximately] 7 nmol/mol greater than it was in 2008, suggesting that the increase will continue in 2009."
