Table 3. Top 10 countries with highest technical HCH use (Li et al., 1999)Number Country Total usage (kilo tonnes)1 China 44642 India 10573 Soviet Union 6934 France 5205 Egypt 4796 Japan 4007 United State 3438 Germany East 1429 Spain 13310 Mexico 132China started production and use <strong>of</strong> technical HCH in 1952. For the 31 years from1952 to 1983, the total amount <strong>of</strong> technical HCH produced reached more than 4million ton in China, almost half <strong>of</strong> the total global usage. Production and usage <strong>of</strong>technical HCH in Japan began after World War II and accelerated steadily until1971 when a ban was implemented on this chemical. Accumulative production andconsumption <strong>of</strong> this insecticide up to the ban has been estimated at 400 kilo tonnes.Total HCH residue concentration in different environmental compartments in Chinaand Japan were comparable, and among the highest level in the world. This is notsurprising since the total average usage <strong>of</strong> technical HCH over arable land in Chinawas similar to that in Japan. In the former Soviet Union, technical HCH was one <strong>of</strong>the most widely used insecticides from 1940s to 1980s. <strong>The</strong> most extensive areas <strong>of</strong>arable lands on the territory <strong>of</strong> the former Soviet Union were in Russia, Ukraine,and the middle Asian republics.Global technical HCH usage trendsGlobal technical HCH use trends from 1950 to 1995 are depicted in Figure 3. Threesignificant decreases <strong>of</strong> global technical HCH usage are apparent in the figure. <strong>The</strong>first one started in 1973 after Japan and other countries, mostly the developed ones,banned the use <strong>of</strong> this pesticide. <strong>The</strong> second started in 1983 when China banned theuse <strong>of</strong> technical HCH, and the third one occurred around 1990 when India bannedtechnical HCH usage in agriculture and the former Soviet Union banned the usage<strong>of</strong> this chemical (Li et al., 1999).<strong>Academy</strong><strong>Publish</strong>.org - <strong>The</strong> <strong>Impact</strong> <strong>of</strong> <strong>Pesticides</strong>291
