The Back Ground

For over a quarter century the Community Education Center has been working

“Towards alternatives” with programmes geared to protect nature and to better

people’s lives through enhancing knowledge. Since the first meeting between Anita

Fernando chairperson of CEC and Sarojini Rengam, Director, Pesticide Action

Network (Asia and Pacific) in 1994, their work expanded with a broader vision and

determination to make the world a better and healthier place for everyone. The

responsibility of this grave task was assigned to the Vikalpani National Women’s

Federation, which branched out from CEC, in 2001.

Chemical pesticides, which took over the traditional environment –friendly pest

control methods since the Green Revolution, has become a part and parcel of the

farming community in the world and Sri Lanka is no exception. The pesticide and

pharmaceutical industries thrived with ever increasing profits at the expense of poorer

farmers, unhealthy people and polluted environment. Although the level of toxicity

varies, Pesticides are poisons and harm intentionally or unintentionally, all organisms

that come into contact with them. Duped by attractive advertisements and being

unaware of the danger involved, farmers throughout the world continue to use more

and more pesticides. There is no escape from the vicious circle, which begins the

moment one purchases the first bottle of pesticide. Every year there are reports of

many farmers who end their lives burdened with heavy debts by drinking pesticides,

which are supposed to word off pests.

Concerned about the health of women in farming communities who directly come into

contact with pesticides constantly, inside and outside their humble abodes, PANAP

sponsored a survey. On women and Pesticides, which was carried out by CEC in

several parts of the island, in 1995. The findings of this survey involving 506 women

shocked CEC and they started conducting more awareness programmes on the hazard

of pesticides. Chandra Hewagallage, who co-ordinated the women’s activities,

underwent special training on all aspects of pesticides. One such workshop organized

by FAO conducted by Dr. Helen Murphy, medical Epidemiologist and health advisor

in 2000, paved the way for this year –long study on self –monitoring of signs and

symptoms of pesticide poisoning among farmers who spray pesticides.

Similar studies have been conducted in Thailand, Cambodia, Malaysia and Vietnam

too.

Introduction

Sri Lanka is an Agricultural Country where the majority of the population does crop

cultivation as their main occupation. The main constrain of crop cultivation is

controlling pests & diseases, for which most farmers use chemical methods as it is

Easy, Quick & Efficient. But they do not think about the risk that they face during

mixing & application of pesticides.

On one hand people feel short-term acute poisoning signs & symptoms after spraying

of Pesticides, but they do not take that serious unless it is a threat to their normal life

style. On the other hand there is no occupational health history recording procedure in

Sri Lanka and hence connection between clinical signs and effect pesticides is missed.

If they feel serious they are admitted to the hospital & those cases are the only

available records of health problems due to Pesticides, but these records shows only

about 5 % of the acute poisoning cases, so most of the acute poisoning cases are not

recorded. The farmers are continuously exposed to the Pesticides, as farming is the

only option they have for a living. Although they neglect the signs & symptoms,

which are not serious at the moment, accumulation of those effects could lead to

chronic effects on them later.

With this background a study was done to find out all the acute Poisoning signs &

symptoms, which could be noticed by the operator after the spraying of Pesticides.

Farmers were advised to take care to get all the precautions in safety aspects. (Use of

face mask, hat, Clothes to cover all the body, not to use leaking spray tanks, not to eat,

drink or smoke while spraying etc.) However of the farmers did not seem to have

follow these instructions and they have sprayed on the way that they are normally

Page 4: Self –monitoring of Sign and Symptoms of Pesticide ...files.panap.net/resources/Sri_Lanka_Report.pdf · Number of Tanks, Number of hours sprayed, Crops, Volume of the tank, name

4

doing. The reasons for this may be protective clothing are uncomfortable in hot

climate and uneasy to use.

The results showed that 23.6% of the farmers, who were used in the study, did not

have any effect to be recorded after the spraying of pesticides.

Dr. Murphy had classified thirty signs & symptoms in to three categories according to

the seriousness and it is given in the Table Number 1.

Those categories are Mild (1), moderate (2) & serious (3).

Table 1: Classification of signs and Symptoms into Categories

Serial No Sign or Symptom Category 1 Dizziness 1 2 Seizure 3 3 Loss of consciousness 3 4 Vomiting 2 5 Sore throat 1 6 Cough 1 7 Chest pain/ burning/tightness 2 8 Nausea 2 9 Stomach cramps 2 10 Numbness 1 11 Diarrhoea 2 12 Itchy skin 1 13 Sweating 1 14 Staggering gait 2 15 Skin rash/dryness/crack/scales 1 16 Muscle cramps 2 17 Tremor 2 18 Muscle weakness 1 19 Shortness of breath 1 20 Headache 1 21 Exhaustion 1 22 Burning nose 1 23 Blurred vision 2 24 Twitching eye lids 2 25 Insomnia 1 26 Red eyes 1 27 Burning eyes 1 28 Excessive tearing 1 29 Runny nose 1 30 Excessive salivation 1

There were only two symptoms in the serious category. They were Seizure & Loss of

consciousness. 20 farmers throughout the study had reported that had felt the

symptoms in this category. This was reported in Monaragala Sevenagala, Kkirawa

and Kanthle they had felt these symptoms after spraying Tamaron (monocrotophos)

which is a WHO class I pesticide and (Malathion, Paraquat and Carbofuran)

Tamaron and Malathion banned in Sri Lanka, it is necessary to find out how

they come to the market. Most of the farmers had felt only mild symptoms.

(52.5%)

Materials & Method

This study was conducted using the voluntary members in the partner organizations of

the “Community Education Center” over a period of one year. 22 members were

trained to conduct the study by the help of Dr. Helen Murphy facilitated by

S.N.Lasantha Rathnaweera Research officer and Subhash S. Rathnaweera Agriculture

officer two officers from the Department of Agriculture. This was a “training of

trainers” session of Five days, which included the following subjects.

Identification of farmers for the study

Identification of Signs & symptoms correctly

Method of training them for the study

Method of recording the signs & symptoms

Method of entering the data in special sheets provided.

After the training, volunteers went to their destinations & selected the farmers who

are spraying pesticides, for the study. The selected numbers of farmers from each Site,

Partner organization of CEC who did the study are given in the table 2. There was no

special reason other than the destination of the Partner organizations, to select these

areas, but the majority of population of these areas is farmers.

The farmers were given one-day training by the volunteers to identify the acute signs

and symptoms. Most signs are common & therefore it was necessary to identify &

decide whether the effects are actually due to pesticide exposure. The farmers were

given a format to mark the signs & symptoms that they felt within 24 hours after each

spray session. Those formats were collected & data were entered by the trainers in to

the special sheets developed by the two officers of DOA, which could facilitate the

data entry in to the computer for analysis. These sheets were sent to the CEC head

office at Malabe. A data entry operator Inoka Udayangani Samaranayake entered data

to the computer for analysis and the findings one as follows are reported here.

This sheet contained Name, address, Gender of the application, Date of application,

Number of Tanks, Number of hours sprayed, Crops, Volume of the tank, name of the

pesticide and the all Signs/Symptoms marked in a schematic diagram farmers had

only to fill the relevant information and mark the Signs/Symptoms that they feed

within 24 hours after application of pesticides.

Results

1. Monaragala

The study was performed by the members of the Community Resources

Protection Center in the area. They have selected 59 farmers for the study out of

which 9 were female. The farmers had used 23 types of pesticides as well as

pesticides mixtures in a single tank. 15 spray sessions were pesticides mixtures.

Farmers had used chlorpyrifos in 165 sessions, which is the highest number in the

Monaragala area in this study. Pesticides used are given in Figure Mo.1

Monocrotophos (Tamaron) had been used in 16 spray sessions. This WHO

class I pesticide is banned in Sri Lanka since 1995. Therefore further

investigation should be carried out to find out how this pesticide has gone to

the farmer
