    • This compares badly with US state of California where the annual reported pesticide poisonings is 0. The reduction in might be due to changes in the pesticides used, although a decrease in the number of workers covered by the National Insurance Company may have led to under reporting. VanWendel de Joode. More than workers in banana plantations have become sterilised as a sideeffect of applying DBCP Thrupp, A more recent estimate revises this to as much as 10, workers sterilised Schonfield et al.

    Subsequent severe psychological repercussions of being sterilised include impotency, severe depression, despondency, grief and confusion. The men are subject to social isolation and ridicule.

    Thrupp, The number of registered poisoning cases can be assumed to be lower than the actual number of poisonings as monitoring is based on voluntary information provided by poison victims and physicians. There has been an almost constant increase in registered poisonings between ] and from to Children under 5 years are highly affected, possibly due to the lack of adequate storage facilities for pesticides on the fanners' property Fig.

    The major risk group is men between 15 and 44, who represent the largest part of the agricultural working force. In , 42 lethal intoxications occurred, no data are available for Global Pesticide Campaigner, Vol. University of Hannover Table 4. Analysis of registered pesticide poisoning cases in Costa Rica in Guatemala The estimated number of pesticide poisoning cases is estimated to be in the range of 11,, per year. Diaz-Ramo, P. New York, USA A survey of farmers in the Fraylesca region, Chiapas found that farmers did not use any specific protective clothing and that dermal exposure to pesticides during spraying accounts for the main health risks.

    Work clothes are often worn for several days in a row before being washed. A four year 22 Chemical Pesticide Markets, Health Risks and Residues intervention programme found that communication and training had a favourable impact on comparatively simple, cheap safety practices used by farmers, while the more cumbersome practices were not employed for long. Atkin, J. CAB International, UK A study in the Yaqui Valley of Sonora, Mexico, comparing two groups of 4- and 5-year-old children who were very similar except in their levels of pesticide exposure found that long-term exposure to pesticides may impair children's brain function.

    The two study groups of children share the same genetic and cultural background, eat the same foods and drink the same water. However, the first group live in the valley, a farming area with relatively intense pesticide use; two crops per year and up to 45 pesticide applications per crop using organophosphates, organochlorines and pyrethroids. Contamination of the local population has been documented, with women's breast milk containing levels of lindane, heptachlor, benzene hexachloride, aldrin and endrin all above limits established by the FAO.

    In contrast, the second group live in the foothills where most families are involved in ranching and pe. The children living in the valley were found to have significantly less stamina and hand-eye co-ordination, poorer short-term memory and were less adept at drawing a person than those children from the foothills.

    An anthropological approach to the evaluation of preschool children exposed to pesticides in Mexico. Environmental Health Penpectives, , June Summarised from: Pesticide Action Network North America Updates Service, June 5, Nicaragua In , cases of pesticide poisoning were reported through the official health system. The actual number of cases is estimated to be about 10, per year. Pesticide Action Network North America Updates Service, May 19, A survey of 36 men who suffered an accidental, work related organophosphate poisoning were found to perform significantly less well at a series of neuropsychological tests including a battery of WHO tests than a control group.

    Rosenstock, L. Pesticide Action Network North America Updates Service, May 19, Middle East Between and , there were recorded poisonings with 26 fatalities linked to endrin-contaminated flour. There have been at least deaths from a single case of dieldrin-contaminated water. Schonfield, A. In , of the 15, pesticide poisoning cases reported in 27 provinces as a result of agricultural use, the majority were caused by organophosphate insecticides.

    Pesticide-Residue Relationship and Its Adverse Effects on Occupational Workers

    OP Poisoning In , the National Statistics Bureau in China reported 49, pesticide poisoning cases accidents and suicides in 27 provinces, including deaths. The reporting system was only set up in and needs improving; some areas have not established a reporting system while in other areas reporting is limited. Chen, S. Since , another poisonings have been attributed to the same cause. Thiers, P. Global Pesticide Campaifiner, Yol4 No 1, March India A study on pesticide poisoning found that out of pesticide poisoning cases, only were reported to the hospital. The study uncovered farmer practices that included exposure to spray drift and use of the mouth to siphon pesticides from the container.

    Saloke, Y. The survey also concluded that in areas of economic deprivation, a farmer will not spend money on protective clothing and will only value their health when they feel financially secure. If it is provided free or as a subsidised rate, a farmer might use it but if it hampers productivity at all, he will discard it.

    CAB International, Wallingford, UK Pesticide Exposure and Health Effects 25 Indonesia In , a survey of farmers who spray pesticides on vegetable crops found 69 different signs and symptoms affecting the health of sprayers during the spray season. Symptoms were only recorded if they arose during or within a few hours of the spray operation. The most fi'equently observed are shown in Table 5. Table 5. Frequency of symptoms experienced by a group of farmers in Indonesia after spraying pesticides.

    I, NO. Sahabat Alam Malaysia "Workers campaign against paraquat". Dirty Dozen Campaigner, September In a study, every surveyed pesticide spray applicator working regularly with dimethoate reported suffering "often" from nausea, sore eyes and headaches, the symptoms of organophosphate poisoning. Other studies have indicated that this insecticide can cause anxiety and depression in people who have been regularly exposed. A third of the workers had two or more symptoms consistent with pesticide poisoning. Cornwall, J. Proceedings of the International Workshop, May , Asian Institute of Technology, Thailand Pesticides News 38, December , page 16 Pakistan A UN report estimated that approximately , people a year are poisoned by pesticides in Pakistan of which 10, die.

    Dawn, 26 August A survey of three hospitals found 52 people treated for non-suicidal pesticide poisonings. Heong, K. International Journal! Pest Management 40 2 Govcrnment hospitals reported cases of pesticide poisoning between and Philippine Daily Enquirer, June 1, Another report by the National Poisons Control and Information service listed poisoning cases between January and March in the National Capital region alone. Hickey, E. While they generally perceive pesticides as hazardous and know that contamination should be avoided, protective measures are rarely taken. Gloves and boots were not generally worn.

    Knapsack sprayers are widely used and the survey concluded that applicators face a high level of pesticide exposure, particularly dermal. Saloke, V.

    Why pesticides are bad for humans?

    Giongco-Baylon, H. Unpublished paper Comparisons of farmers with long-term exposure to pesticides in rice production with farmers with no history of exposure showed that the magnitude of chronic health effects and health costs are directly related to pesticide exposure and that the net benefits of insecticide use are negative. Pingali, P. Loevinsohn, M. However, these data rely on case reports of Government Hospitals and some private clinics and therefore the number of actual poisoning cases are assumed to be understated Sinhaseni,. A survey about poisoning cases among agricultural workers concluded that only 2.

    Official data from the Epidemiology Division shows the number of occupational poisoning cases occurring in was Additionally, labour costs in the form of lost labour days have to be calculated. The costs per labour day are calculated with baht per day, the loss of labour days amounts to 3 days for hospital treatment, and 0.

    Relating the poisoning cases to the average costs from medical treatment and lost labour days assessed in that survey to be If we consider that the available statistics underestimate the actual poisoning incidents and that the death cases are not included, the calculated costs may serve as the lower boundary of the actually implied health costs.

    To conclude to a more realistic amount of the health cost assessment results of the study of Whangthongtham are used to calculate poisoning cases in relation to insecticide market volume. The poisoning cases per hectare and the intensity of insecticide use are needed for this calculation, Firstly the reported poisoning cases are mainly due to insecticide use and are therefore related to the quantity of insecticides used. Secondly, poisoning cases are not location specific and finally, the hazardousness of the pesticides used is comparable for all crops.

Chen, C. Both operate through inhibiting the enzyme acetylcholinesterase , allowing acetylcholine to transfer nerve impulses indefinitely and causing a variety of symptoms such as weakness or paralysis. The recoveries for the pesticide residues ranging from
