Temporal Trends of Body Burden
Since being banned, the average human body burdens of DDT and PCB have been declining. Since their ban in 1972, the PCB body burden is 1/100 of what it was in the early 1980s (Weschler 2009). Monitoring programs of European breast milk samples have shown that PBDE levels are increasing. An analysis of PBDE content in breast milk samples from Europe, Canada, and the US shows that levels are 40 times higher for North American women than for European women, and that levels in North America are doubling each year.

Famous quotes containing the words temporal, trends, body and/or burden:
“Death is not an event in life: we do not live to experience death. If we take eternity to mean not infinite temporal duration but timelessness, then eternal life belongs to those who live in the present.”
—Ludwig Wittgenstein (1889–1951)
“Thanks to recent trends in the theory of knowledge, history is now better aware of its own worth and unassailability than it formerly was. It is precisely in its inexact character, in the fact that it can never be normative and does not have to be, that its security lies.”
—Johan Huizinga (1872–1945)
“The body sins once, and has done with its sin, for action is a mode of purification. Nothing remains then but the recollection of a pleasure, or the luxury of a regret.”
—Oscar Wilde (1854–1900)
“Come unto these yellow sands,
And then take hands.
Curtsied when you have and kissed
The wild waves whist,
Foot it featly here and there;
And, sweet sprites, the burden bear.”
—William Shakespeare (1564–1616)
