LONDON, 7 September - The nuclear tests conducted in the United States in the fifties
have also contaminated areas
Western Europe: and 'This is the conclusion to which'
a joint scientific study English lasted 160 years.
examinations conducted by Rothamsted Research on soil samples collected in the region of Hertfordshire (North London) have found considerable traces of plutonium, the Times, can only
back to the nuclear tests held in Nevada between 1952 and 1953.
The discovery 'was possible thanks to a lengthy survey of
organized in the region
English from 1843, when John Lawes and Joseph Henry Gilbert
began to study the ground to monitor the effect of different fertilizers
yields and quality 'of the land.
From there 'on, every year they were extracted and stored
clods of soil that allowed
a historical reconstruction of the effects of' human activity on the ground.
''Events like the industrial revolution, the introduction of oil and acid rain
can all be found in different chemical compositions
of our samples on file,''he confirmed
Professor Keith Goulding of Rothamsted Research.
The study will be 'presented this week at the University'
Exeter (in Devon, southwest England) under the
