Forum on aerial spray study set


A PUBLIC forum to discuss results of a study initiated by the Department of Health (DOH) on the effects of aerial spraying will be conducted on July 9.

The forum will start at 8 a.m., at the Mindanao Training Resource Center of the Davao Medical School Foundation in Bajada, Davao City.

Dr. Allan Dionisio of the National Poison Management and Control Center (NPMCC) will discuss the results of the study in behalf of health expert groups, NPMCC and the Philippine Society of Clinical and Occupational Toxicology (PSCOT), which conducted the DOH-funded study.

The study noted the alarming symptoms of pesticides among the residents near a banana plantation.

The results showed the presence of pesticide in the human blood, the soil and air samples outside the banana plantation area.

The study was conducted for DOH in 2006 in response to complaints by residents of Sitio Camocaan in Hagonoy, Davao del Sur residing near a banana plantation.

The DOH commissioned the study to address the health and environment issues raised by University of the Philippines-Manila toxicologist Dr. Romeo Quijano in 2000.

The study utilized the comparable socio-economic and demographic profiles of Camocaan and Baligawa.

Camocaan is adjacent to a banana plantation, while Baligawa is 15 kilometers from the nearest banana plantation, but is 1.5 kilometers away from two mango pantations.

Some of the conclusion of the study showed 82 percent of respondents from Camocaan were indirectly exposed to aerial spraying and 52 percent of whom experienced eye pain, eye tearing, headache, eye redness, eye itchiness, dizziness and skin itchiness. These were not observed among residents in Baligawa.

Camocaan residents had lower mean scores for mental status examination and children are delayed in development compared to those examined from Baligawa.

The study recommended the termination of aerial spraying of pesticides and to shift to organic farming techniques. (Jade C. Zaldivar)

Neuro-developmental delay in

Neuro-developmental delay in children of Camocaan

Scientists who are experts in this field study the behavioral response of the children themselves. They let the children crawl, sit up, roll over, walk, etc etc. and study population runs up to hundreds... It's just like those babies studied in discovery channel or national geographic sa tv.

Dr Dionisio and co-workers only interviewed mothers who were forced to recall how many months or years their children were when they sat unsupported, walked a few steps, drew circles with crayon etc.

Can a mother of a 10-year-old really recall all these details? Mothers usually keep records but I find it very difficult to believe that mothers of a poor community can recall these information with such accuracy. Did they consult their baby's books?

Is this the scientific way to conduct such a study? Do the results of mother recall really pinpoint effects of aerial spraying on developmental delay in children. Sana magbasa naman sila ng published methods on how to conduct this type of study, sana nga para hindi na tayo magkakagulo...

Baka Indonesia na ang major exporter of bananas sa Japan...Can the good doctors see this larger picture?

I attended one of Dr.

I attended one of Dr. Dioniso's talks. In fairness to him, nagpakita naman siya through powerpoint presentation ng mga drawings and sketches na ginawa ng mga bata na allegedly may mahinang neuro development. Ang di ko lang magets, yung nagcomment na mothers lang ang tinatanong, kaw po yata ang hindi scientific.

How did you know na ganun nga lang kasimple ang method of study na ginawa nila? Were you there nung nagconduct ng study? Don't immediately jump into conclusion. Baka mapahiya ka lang sa mga sinasabi mo. Though we don't deny na may lapses din talaga ang study. Pero mga professionals din ang gumawa nun and mga scientists pa. I don't think na hindi nila naisip yung simpleng concern mo before they conducted their study.

As to being overtaken by Indonesia to be the major exporter of bananas, who cares? Is that the only solution to make our country prosper? I-sacrifice ba talaga natin ang welfare ng citizens just for that "import dependent- export oriented policy"? Think twice my friend.

Mothers should be able to

Mothers should be able to recall..

That's what Dr Dionisio said in his talk in Davao. He said I am a father, so it is not expected that I can recall when my child sat without support, but all mothers can recall.

So there is developmental delay because the mothers interviewed in Camocaan said so... Wala namang bata na 6 months old na respondent sa study nila. The older children were not asked to draw.

Ganoon ba talaga ang pagsusuri sa mga bagay na ganito...

Ewan? Lalo akong naguguluhan. I googled scientific publications on child development pero iba ang method ng mga scientists na nabasa ko sa journals online.

Hindi naman ako UP Medical school na graduate pero nag iisip naman ako at nag analyze sa mga pinagsasabi ni Dr Dionisio sa speaking engagements niya sa Davao, kung saan saan mo naman siya makita ah!

Why does Dr. Dionisio keep

Why does Dr. Dionisio keep on talking about the results of their study instead of meeting with the health workers or the baranggay captain in Camocaan so they can address the health concerns in Camocaan? If his team is really concerned about those people who are sick, why did they not endorse these people so they will get proper treatment right after their medical examination sometime in 2006?

It's has been 3 years and up to now these people have not been treated!

Is this the concern he is always talking about to the media? I find it hard to believe that he is concerned.

To the comment above: Allow

To the comment above: Allow me to react to your comment criticizing the report of Dr. Dionisio's team.

Well, I think you're right that the victims need outright medical attention. But I don't believe it's part of the scope of the work of the research team to do such. Yes, some of them are medical doctors.

However, they were commissioned to conduct an investigation/research study. A separate body or entity might be tapped to address health concerns of the victims of aerial spray. The research study itself is already a great help not just for the victims of aerial spray but also for all of us who are also prone to a similar dilemma.

If you're suggesting that Dr. Dionisio or even Dr. Quijano and all those scientists who study these cases to stop with their findings, then I would say you're not serious with your concern for the victims.

In the first place, how would you treat the victims without thorough examination of the underlying circumstances that led to their condition? Similarly, it wouldn't be beneficial if we just focus on helping the victims without having those who practice aerial spraying held liable. It's like you're putting a band-aid over an open wound, without even treating the wound itself to prevent from worsening.

On this issue, it's alarming

On this issue, it's alarming to know there have been cases cited in the study that are unfounded. One good example of this is the alleged “death” of twins Marlon and Marvin Dulla, who are, in fact, well and alive right now. Some of the cases were also said to be concocted like claims that male residents have been sterile and animals have died all due to aerial spraying in banana plantations.

For people's sake, these are indeed alarming since all of these come from a scientific study commissioned by DOH. But now that these claims have been challenged as to their veracity, it is also worth questioning if the studies on which we have been basing our recommendations and decisions for legislation are also truthful and scientific.

Have “scientific studies” been reduced to something like school theses that can be manipulated and made up just to come up with a result so as to pass a subject? This is a serious case that affects a lot of stakeholders. Thus, people should also be careful and critical-minded in looking into these studies which claim “scientific truths” that can actually be made up and manipulated.

For the sake of fairness and for the sake of science, let us put a stop to the concocting stories and citing unfounded cases which stain the reputation of science.

For curiosity, I went to

For curiosity, I went to Camocaan and talked to the locals including the chieftain (or barangay captain). None of the residents knew who those 'sick' persons are. The barangay is nowhere near the description of Quijano as a 'desolate' place. Dr. Dionisio would be more credible if they would show the persons affected - with chloracne, with etu in blood, etc... These residents should be treated as soon as possible (if they are real!) and have the plantations and chemical suppliers resolve the issue (if there is really one).

I heard the mayor exposed in recent public hearings in Davao City and Camocaan that the person Quijano reported as dead is actually alive and has a family! What does Quijano have to say about that??

My suggestion to all, don't believe any side.. but go to Camocaan and talk to the people, see for yourself, listen to them (and to their 'anger' about how they were depicted in these studies)...

Abangan! I really look

Abangan!

I really look forward to knowing what the experts in UP Manila have to say about the study conducted by Dr Dionisio and others... Abangan!

What is more urgent to me now is knowing what the good doctors have done about their findings of children who are severely malnourished, when they say they observed stunting and wasting...all severe cases of malnutrition...These conditions are really going to affect their mental health! What a pity!

Makatulog sila without doing anything about these children for 3 years??

It's shocking to me!! Then you see him roaming around Davao giving all these talks to captive audience, telling the same story but not doing anything.

Anong kasalanan ng mga bata na hindi sila inaasikaso?

Are they just numbers or statistics to the "poison doctors" -- specialists in toxicology??

It's extremely disturbing behavior...to say the least.

Come on Dr Dionisio! It's

Come on Dr Dionisio!

It's part of your Hippocratic oath to, at the very least, give the names of the sick people to the medical workers in Camocaan..

Hellooo??? How come those names are not yet out in the open after three long years?

For all I know, that person could have died already from medical neglect!!

Don't talk about band aid! It insults the intellect.

Dr. Quijano really exists.

Dr. Quijano really exists. FYI, he is the president of PAN Asia Pacific (an international organization concerned with monitoring and studying pesticides and other environmental hazards)...Before you (the one who commented prior to this) jump into conclusion, do some research also about the names identified. That would lessen your bias.

Another thing, you asked what Dr. Quijano would say about the issue. Well, he has said a lot already. You mentioned that Dr. Dionisio is more credible than Dr. Quijano. Well, they have almost similar findings. In fact, Dr. Dionisio came into the scene to investigate the claims of Dr. Quijano. Had not Dr. Quijano exposed his isolated study, do you think Dr. Dionisio's team would have conducted its study?

Another thing, it is not enough to just ask the side of the barangay officials or even residents in the locale. There is also a need to process the data and investigate through scientific processes. Chemical analyses (both qualitative and quantitative) must be done, as well as medical laboratory tests.

Now, a mere visit and interview with local residents would not suffice, We need to dig deeper up to the atomic-level to prove our claim. Unless the barangay captain you asked is a scientist, perhaps he can't articulate well enough the scientific perspective, and only through the scientific processes could we lay a strong foundation or grounds for the case.
