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:
“Social questions are too sectional, too topical, too temporal to move a man to the mighty effort which is needed to produce great poetry. Prison reform may nerve Charles Reade to produce an effective and businesslike prose melodrama; but it could never produce Hamlet, Faust, or Peer Gynt.”
—George Bernard Shaw (1856–1950)
“A point has been reached where the peoples of the Americas must take cognizance of growing ill-will, of marked trends toward aggression, of increasing armaments, of shortening tempers—a situation which has in it many of the elements that lead to the tragedy of general war.... Peace is threatened by those who seek selfish power.”
—Franklin D. Roosevelt (1882–1945)
“If the body be feeble, the mind will not be strong.”
—Thomas Jefferson (1743–1826)
“Our inherent human charity and our religious beliefs will be taxed to the limit. No poor, rural, weak, or black person should ever have to bear the additional burden of being deprived of the opportunity of an education, a job, or simple justice.”
—Jimmy Carter (James Earl Carter, Jr.)
