Absence of domestic legislation and regulations; Inadequate institutional facilities; Lack of personnel trained in these fields; Absence of poison control centres; The power of private interests; and The pressure of more urgent needs. These shortcomings have led some chemical companies to build new facilities or move existing ones to countries where legislation is either lax or nonexistent and has facilitated the export of toxic wastes to poor countries. It has become clear that, in the absence of a concerted and cooperative effort, many governments, especially in developing countries, will fall increasingly behind in establishing the means and the expertise necessary to tackle the highly complex health and environmental problems resulting from the use of chemicals.

Regional information resources for pesticide research R. Fernando National Poisons Information Centre, General Hospital, Colombo, Sri Lanka Pesticide poisoning is a serious health problem in many developing countries. Making information available to health professionals and the general public is essential in its prevention. In viezv of the success of the National Poisons Information Centre established in Sri Lanka in 1988, a proposal for a regional information network for Asia and the Pacific is presented. With international support, such a network would collect and disseminate information on all aspects of pesticide poisoning to national centres. Pesticides in Sri Lanka Between 1980 and 1986, the domestic supply of formulated pesticides in Sri Lanka increased markedly: for insecticides, it rose 106%; for herbicides, 214%; and for fungicides, 128%. Pesticides, by definition, are harmful to living organisms. Therefore, it is not surprising that misuse or abuse of pesticides has been increasingly responsible for illness and death among humans. Poisoning with chemical pesticides has been reported in Sri Lanka since the 1950s. In the late 1970s, the national morbidity rate from pesticide poisoning was 79 cases per 100 000 people. Suicides accounted for 73% of poisoning cases; occupational and accidental pesticide poisonings were responsible for 17% and 8%, respectively. In 1980, Sri Lanka's suicide rate was one of the highest in the world: 29 per 100000 people. Only Denmark and Hungary reported higher rates in that year (31.6 and 44.9 per 100 000, respectively). An investigation of 407 pesticiderelated deaths in an agricultural area of Sri Lanka revealed that 373 cases or 92% were suicides. It is clear that the common mode of suicide in Sri Lanka is ingestion of liquid pesticides. 204
