The Scientists have found traces of lead, transported by the winds from the British mines, which in the late 1100s.Becket , The Source of The Ice core data
, though, had other plans.
In the same way that trees, detail rings of growth in a year, so glacier compact a record of the chemical composition of the air trapped in the bubbles in the annual build-up of ice.Peveril Castle in The Peak District served as the administrative headquarters of lead mining in the area
the analysis of the 800-year-old ice cream with a highly sensitive laser, scientists were able to see a huge surge in lead in air and dust, captured in the 12Th Century .
Atmospheric modeling showed that the item was carried by the winds from The North , the West, in the United Kingdom, where lead mining and smelting boomed in the late 1100s.
The researchers were able to get the physical records from The Ice posted to result tax records, and silver-production in England.
But the production of the metal was clearly in connection with political events, the authors of the latest Research .
"of 1169-70 time, there was a great quarrel between Henry II and Thomas Beckett , and, the conflict is manifested through The Church refuses to work with Henry and you actually see a decline in production this year," said Prof Christopher Loveluck, University of Nottingham.A graphic from the study shows The Rise and fall of lead production in the late 1100s
"To the prison with the Pope, Henry promised to equip and build a lot of large monastic institutions very, very quickly," said Prof Loveluck.
"And, of course, large amounts of lead were used for roofing of the great monastery.
The researchers say that their data also show clearly enough that the clear connections between production, lead to rising and falling during times of war and between the reigns of different kings in this period between 1170 and 1220.
they argue that the idea that air pollution began with the Industrial Revolution are wrong.
