Introduction..1 Issue: Spraying of Alar on Apples Consequences: creation of panic
among Americans Why: … People believe that
consuming apples treated with Alar was the most potent causing cancer substance

Scenario: American public was panic and got out of control
Reactions: Schools removed apples from menus. Parents poured apple products down sink drains. Stores pulled apples out from shelves. Apple industries stopped using Alar-treated apples

Trademark name: Alar Common name: Daminozide Chemical names: N-
dimethylaminosuccinamic acid, succinic acid 2,2-dimethylhydrazide, and butanedioic acid mono (2,2-dimethyl-hydrazide)
Other trade names: Kylar, SADH, B-nine, B-995, and Aminocide
Group: growth regulator, pesticide
![Page 32: SKAM-17 2004 BALOK: ALAR ISSUE ON APPLES](https://reader031.fdocuments.in/reader031/viewer/2022020301/58ac588c1a28ab8e258b59eb/html5/thumbnails/32.jpg)
Advantages of Alar … delay ripening on fruits … attain a better deeper red color,
and a firmer texture …prevent premature dropping, thus
provides apple growers a better yield of a uniform crop
…enable entire orchard be harvested just once, instead of periodically over 6 weeks
… uniformly apple shapes can extend the usual six- to eight-month shelf life or more
![Page 33: SKAM-17 2004 BALOK: ALAR ISSUE ON APPLES](https://reader031.fdocuments.in/reader031/viewer/2022020301/58ac588c1a28ab8e258b59eb/html5/thumbnails/33.jpg)
Disadvantages of Alar Alar is absorbed through leaves,
roots, and stems. It is translocated and accumulated
in roots, fruits, and elsewhere. Alar penetrates the apples’ pulp
and cannot be washed, cooked or peeled off. Thus, chemical is consumed as we eat apples.
![Page 34: SKAM-17 2004 BALOK: ALAR ISSUE ON APPLES](https://reader031.fdocuments.in/reader031/viewer/2022020301/58ac588c1a28ab8e258b59eb/html5/thumbnails/34.jpg)
Apples The Environmental Protection
Agency (EPA) officials said Alar is used majority on red apples (like McIntosh, Cortland, Jonathan, and Red Delicious)
Alar is not used on green apples, like Granny Smith variety, although it is used on Golden Delicious apples
![Page 35: SKAM-17 2004 BALOK: ALAR ISSUE ON APPLES](https://reader031.fdocuments.in/reader031/viewer/2022020301/58ac588c1a28ab8e258b59eb/html5/thumbnails/35.jpg)

FINDINGS
![Page 42: SKAM-17 2004 BALOK: ALAR ISSUE ON APPLES](https://reader031.fdocuments.in/reader031/viewer/2022020301/58ac588c1a28ab8e258b59eb/html5/thumbnails/42.jpg)
Results Results are categorized into four
aspects: 1a. Journals + newspapers provided
information, facts, toxicological tests, and public concerns on Alar.
1b. Internet listed more than 600 references. All sources were on Alar related issue!
![Page 43: SKAM-17 2004 BALOK: ALAR ISSUE ON APPLES](https://reader031.fdocuments.in/reader031/viewer/2022020301/58ac588c1a28ab8e258b59eb/html5/thumbnails/43.jpg)
Results 2. Conducted studies by Carson’s
(1964), Oser (1966), Toth (1970, 1973, & 1977), National Cancer Institute (1978, 1979), Lapsley (1985), and Environmental Working Group (1998) served as toxicological basis, indicated that Alar broke down into UDMH.
Samples found to develop several kinds of cancer (kidney, liver, blood vessels, uterine, and blood vessels).
![Page 44: SKAM-17 2004 BALOK: ALAR ISSUE ON APPLES](https://reader031.fdocuments.in/reader031/viewer/2022020301/58ac588c1a28ab8e258b59eb/html5/thumbnails/44.jpg)
Results 3. EPA Chicago, Illinois provided printed
materials on Alar. An environmental group (1989) claimed
that children face a massive health problems from pesticide residues in food which caused cancer and nerve damage.
They charged EPA failed to responsible on the exposure tolerance levels of children and infants.
![Page 45: SKAM-17 2004 BALOK: ALAR ISSUE ON APPLES](https://reader031.fdocuments.in/reader031/viewer/2022020301/58ac588c1a28ab8e258b59eb/html5/thumbnails/45.jpg)
Results Forefront in the public’s eye is the
issue of Alar on apples. The EPA said effects on humans
consuming fruits treated with Alar were unknown.
The toxicity studies were conducted using animals because to administer such chemical tests to human, it is illegal.
![Page 46: SKAM-17 2004 BALOK: ALAR ISSUE ON APPLES](https://reader031.fdocuments.in/reader031/viewer/2022020301/58ac588c1a28ab8e258b59eb/html5/thumbnails/46.jpg)
Results4. Results on the use of Alar on apples
from 150 questionnaire surveys distributed to Baptist Student Center residents, Southern Illinois University at Carbondale, Illinois can be summarized as follow:
A. Majority of them were not certain if Alar was a health risk. They wanted more evidence in deciding about the safety use of Alar on apples;
![Page 47: SKAM-17 2004 BALOK: ALAR ISSUE ON APPLES](https://reader031.fdocuments.in/reader031/viewer/2022020301/58ac588c1a28ab8e258b59eb/html5/thumbnails/47.jpg)
Results
B. They were not sure the laboratory tests using animals were consistent. They needed more knowledge and convinced data about the certainty in laboratory tests for humans;
![Page 48: SKAM-17 2004 BALOK: ALAR ISSUE ON APPLES](https://reader031.fdocuments.in/reader031/viewer/2022020301/58ac588c1a28ab8e258b59eb/html5/thumbnails/48.jpg)
Results
C. A high percentage of BSC residents concerned about chemicals on their food. Yet, they lacked certainty whether or not Alar to be banned. They seemed to lack of knowledge about Alar on apples; and

ResultsSummary of the four orchard
apple owner opinions are as follows:
1. The Grammers Orchards used Alar but discontinued in 1990. The owner disagreed to ban Alar because it used mainly in banana, not on apples. The discontinuation was due to the public displayed of an uneased and concerned on economic reason;
![Page 52: SKAM-17 2004 BALOK: ALAR ISSUE ON APPLES](https://reader031.fdocuments.in/reader031/viewer/2022020301/58ac588c1a28ab8e258b59eb/html5/thumbnails/52.jpg)
Results
2. The Flamms Orchards discontinued using Alar many years due to the scare that people did not buy their apples. The Company experienced the decrease in purchasing of apples from public due to the Alar issue;
![Page 53: SKAM-17 2004 BALOK: ALAR ISSUE ON APPLES](https://reader031.fdocuments.in/reader031/viewer/2022020301/58ac588c1a28ab8e258b59eb/html5/thumbnails/53.jpg)
Results3. The Eckert Orchards discontinued
using Alar many years due to public fear.
The manager said, “Alar was good because it increased shelf life, provided apples with pretty color, and a firmer texture. But, due to the public concern and to maintain economy and security of the orchards, the use of Alar on apples was discontinued”; and
![Page 54: SKAM-17 2004 BALOK: ALAR ISSUE ON APPLES](https://reader031.fdocuments.in/reader031/viewer/2022020301/58ac588c1a28ab8e258b59eb/html5/thumbnails/54.jpg)
Results4. The Minton Produce manager
disagreed to ban Alar. He said, “The sign of not applying
Alar on apples was just gimmick. Alar did not pose danger to people. A person must consume 70,000 lbs apples treated with Alar everyday to be at risk of cancer. We discontinued using Alar on our orchard because we concerned on our economic”.

CONCLUSION
![Page 56: SKAM-17 2004 BALOK: ALAR ISSUE ON APPLES](https://reader031.fdocuments.in/reader031/viewer/2022020301/58ac588c1a28ab8e258b59eb/html5/thumbnails/56.jpg)
Conclusions
Several conclusions are made:1. The 1964, 1966, 1970, 1973,
1977, 1978, 1979, 1985, & 1998 experiments using animal samples did not reflects exactly to human beings. The doses applied to the samples might also have different impacts if applied to humans.
![Page 57: SKAM-17 2004 BALOK: ALAR ISSUE ON APPLES](https://reader031.fdocuments.in/reader031/viewer/2022020301/58ac588c1a28ab8e258b59eb/html5/thumbnails/57.jpg)
Conclusions
2. EPA did not confirm to ban Alar on apples. Data from experiments and tests did not convince public … the use of Alar on apples was definitely dangerous or caused severe illnesses, not to mention about cancers.
![Page 58: SKAM-17 2004 BALOK: ALAR ISSUE ON APPLES](https://reader031.fdocuments.in/reader031/viewer/2022020301/58ac588c1a28ab8e258b59eb/html5/thumbnails/58.jpg)
Conclusions3. Baptist Student Center residents
said, “They lacked of knowledge on Alar ... not certain whether or not to ban Alar, even though they concerned about chemicals in their foods. EPA had not decided in banning of Alar. The influence on the banning was due to the media.”
![Page 59: SKAM-17 2004 BALOK: ALAR ISSUE ON APPLES](https://reader031.fdocuments.in/reader031/viewer/2022020301/58ac588c1a28ab8e258b59eb/html5/thumbnails/59.jpg)
Conclusions
4. Apple orchard owners interviewed had mixed opinions. Majority were not aware if using Alar posed dangers. They concerned about public views but at the same time they needed to maintain economy and security of the orchards. Thus, they decided to discontinue using Alar.
