Its relative decline in percentage share of publications is largely due to the emergence of China and other Asian nations. In 2006, China has become the second largest nation in terms of the number of publications within this database. In terms of citations, the competitive advantage of the American “domestic market” is diminished, while the European Union (EU) is profiting more from the ...

Two experiments were conducted at initial concentrations of 3.7 and 12.8 ppm and it was shown that about 80% of the DDT was lost from the soil in two years. The half life of DDT was 319 and 343

The dissipation of the chemical was apparently biphasic; halflife of dissipation 271 days. After one year, 61% of the initially applied radiocarbon was lost from soil. Methanol‐ ...
