Toxic pesticide has unhealthy legacy in Ararat Valley

Lilik Simonyan, a medical doctor and scientist working with the Armenian Women for Health and Healthy Environment NGO was disturbed, but not surprised that traces of DDT was found in the breast milk of all 70 women the NGO tested in the Ararat Valley. The highly toxic and illegal chemical was also found in women tested in an Abovian maternity ward.
The results are alarming, but unfortunately also predictable.
The richly fertile valley is Armenia’s major food basin from which most of the republic’s produce is harvested. The valley is also “rich” in traces of DDT. The chemical pesticide was banned in Armenia in the 1970s, but is believed to still be in use today. A highly stable compound, it is currently seeping into Armenia’s water, land, livestock and even people.
“The problem with DDT is that it lasts forever,” said Simonyan. “Even if people stopped using the pesticide in the 1970s, it would still be in their systems 40 years later. And we believe people are still using it today.”
First developed as a lice killer and insecticide during World War II, DDT was widely used in Armenia and many other countries in Europe and in the U.S. throughout the 1950s and 1960s. A ban on the pesticide was instituted in the U.S. in 1972 after researchers noted that spraying it was a contributing factor in the near extinction of bald eagles and peregrine falcons, by weakening the bird’s eggshells and causing them to crack. Laboratory tests in animals have shown that DDT can cause cancer and other health problems, and DDT exposure has been shown to be associated with premature births and lower birth weight in babies.
There is debate in the international scientific community about whether the ban on DDT in many countries is more helpful than harmful. Many scientific groups have argued that DDT was responsible for eliminating the malarial mosquito. Opponents of the ban contend that discontinuing use of DDT has led to an increase in malarial deaths across the globe. In 2006, the World Health Organization actually reversed its policy on the ban, and now advises it for use in fighting malaria in Africa and other mosquito-ridden areas of the world.
What is agreed upon is that DDT stays in the ground, animal populations and humans for years – even decades – after the pesticide is out of use.
Specialists do not know the real situation with regard to expired chemical pesticides in Armenia, nor do they know how many farmers are using DDT. The Ministry of Agriculture says it is necessary, and yet impossible, to conduct a final inventory of expired chemical pest-killers imported into Armenia since 1997. The ministry is considering an announcement, asking the population to hand over expired chemicals and receive quality chemicals in exchange. But this entails some other, more difficult work: how to preserve or with what means to destroy the collected expired chemical pesticides.
Simonyan said she’s personally seen the largest amount of DDT in the Ararat Valley and the Ararat province in particular. The chemical there has been found in both soil and products made of animal tissues. She said people widely used DDT in the region, which is why it predominates over other revealed chemicals. The organization she heads found DDT in one of the chemical production outlets several years ago, with no such cases being reported later.
In Ararat villages such as Margara, Apaga, Aknashen and Sev Jur village in Armavir Province, DDT is showing up in the bird population. Researchers have noticed that reproduction of storks is low, and one hypothesis is that DDT is the culprit.
Another potential danger spot is Yerevan’s Erebuni, site of a burial ground of expired DDT and other pesticides, put there by the Agriculture Chemistry of Armenia state-run enterprise in 1982. Since then, the area has experienced several landslides.
“There are no destruction mechanisms, and complicated technology is needed. At this point no one is able to find solutions, and the state does not have so much money. The situation is in a state of neglect,” warned Karine Yesayan, Head of the Horticulture Development Department under the Plant Cultivation, Forestry and Plant Protection Agency of the Ministry of Agriculture.
Environmental experts are concerned that the problems at the pesticide dumping ground are getting worse. Simonyan’s organization conducted an investigation into the surrounding soil. They discovered that the concentration of chemical pesticides, particularly that of DDT and hexachlorocyclohexane (another pesticide) exceeds the marginal permissible amount by several hundred times, and has increased in recent years.
Currently, the Global Environmental Foundation through the United Nation’s Food and Agricultural Organization (FAO) has allocated 2.5 million Euros to liquidate the burial ground of toxic chemicals. The program will be launched after an assessment of the situation. Yesayan said the chemicals must first be exhumed from the burial ground, packaged and only later destroyed.
“The residential districts are now closer to the burial site, hence any time the toxic substances may penetrate into the drinking water or reach the population through the soil. In a word, this is dangerous, this is a bomb, immediately next to Yerevan,” said Yesayan.
