DDT is a term that everyone has heard and very few actually know what it is. DDT: Dicholoral dichorbenzen acid, a synthetic insecticide that was used extensively in 1. (A. agriculture B. ailment) and in the control of (……) diseases in all over the world. DDT was first used to protect allied soldiers and civilians against typhus in World War II by killing body lice. At first, the USDA decided that before DDT can officially be used and were recommended for use, they needed to know more about its possible 2. (A. tactility B. toxicity). However, shortly after, limited use was permitted and even the more evidence suggested that DDT may have some acute toxic effects on birds and other animals by being stored in animal 3. (A. fat B. fit) and then being excreted through milk. However, as it always is, when companies are given an inch, they hit a mile. Between 1940 and 1980 at least four 4.(A. billion B. four million) pounds of DDT were used and the annual use peaked in 1964 with the collected four hundred forty thousand and eight hundred tons. DDT was dropped in discriminately, on ponds, 5. (A. waterwalls B. waterways), livestock, even on children. II. Its negative effects DDT acts as a nerve quieter(?) for insects. It was used to control obviously mosquitoes but also elm bark beetles, lice, gypsy moths and many other types of insects. DDT was sprayed by planes, trucks, and even handheld devices. Although the usage of DDT began in the 40s, the majority of people did not realize the magnitude of its negative effects until the 6. (A. 40s and 50s B. 60s and 70s). At first the DDT was very effective in killing the desired insects but at the same time, it killed many 7. (A. beneficial B. fictional) insects such as bees or spiders. Unless we do bring these chemicals under better control, we are certainly headed fro disasters. III. Rachel Carson When one hears about DDT, one almost always hears of Rachel Carson. Rachel Carson was one of the first and obviously one of the well-known scientists to 8. (A. protest B. protect) the use of DDT. In the small town of the west side of Maine, a biologist called Rachel Carson received a letter from a friend, telling her that all the birds in her garden had died soon after the sprayers had flown over. Carson started investigating. She discovered that the 9. (A. indistinctive B. indiscriminate) spraying pesticides was killing not just pests but insects beneficial to agriculture. IV. Silent Spring Carson’s book Silent Spring published in 1962 helped to create worldwide concern for environmental preservation. It was a bestseller and eventually led to the 1963 U.S. 10. (A. bet B. ban) on DDT as well as restrictions and bans in other countries. We poisoned with careless flies in the streams and the poison travels from link to link in the food chain and the birds in the lake margins became its victims and the following springs are silent with no robin song. Rachel Carson died of 11. (A. cancer B. canon) in 1964, but she was later awarded the presidential medal of freedom. She will forever be known for her actions in the fight against DDT. Carson realized one of the most horrible and lasting effects of DDT was its effect on birds, especially raptors. The high levels of DDT in the bird tissues alter the calcium processes, therefore, resulting in the production of eggs with the extremely 12. (A. fragrant and thick B. fragile and thin) shells. This was a very horrible blow to the populations of many birds. The young will never hatch because the eggs will be 13. (A. crushed B. crashed) during incubation and therefore the population numbers plummeted. Certain species were hit harder than others such as brown pelicans, pare falcons, ospreys and bald eagles. Many of these birds are just now today finally beginning to rebound (rebel?) from the effects of DDT. Although today we may look back upon the use of DDT and think how could people have been so stupid to spray this chemical on their 14. (A. children B. chicken), in their houses and yet today these risks still exist. They are just from different sources. Part II: Mark T/F according to the passage you’ve just heard (5/ea) 1. Before DDT was fully permitted to be used, it had been widely on controlling the population of pests. 2. DDT can accumulate and are stored in fatty tissues of animals and caused severe damage. 3. Though the DDT was very effective in killing harmful insects, it killed many beneficial insects. 4. When Rachel Carson found birds in her garden died after sprayers of DDT flew over, she started investigation. 5. Carson’s book Silent Spring, published in 1965 aimed to raise worldwide concern for environmental preservation. 6. The lasting and severe effects DDT had on birds is to damage their reproduction systems, leading to poor egg quality or no eggs at all.
