Waste Management Series. Minimum Requirements for the Handling, Classification and Disposal of Hazardous Waste. Project Manager: L. Bredenhann, Department of Water Affairs & Forestry Co-ordinated by: Dr H.O. Fourie, Ockie Fourie Toxicologists (Pty) Ltd Editor: Mrs K. Langmore I THE WASTE MANAGEMENT SERIES This document forms part of the Waste Management Series, produced by the Department of Water Affairs & Forestry. Thus far, the series comprises: Document 1: Minimum Requirements for the Handling, Classification and Disposal of Hazardous Waste. Document 2: Minimum Requirements for Waste Disposal by Landfill. Document 3: Minimum Requirements for the Monitoring of Water Quality at Waste Management Facilities. Document 1, Minimum Requirements for the Handling, Classification and Disposal of Hazardous Waste, sets out the waste classification system. In this, wastes are placed in two classes, General or Hazardous, according to their inherent toxicological properties. Hazardous wastes are further subdivided, according to the risk that they may pose at disposal, using a hazard rating. In this way, a less hazardous waste is distinguished from an extremely hazardous waste. Wastes with a hazard rating of 1 or 2 are very or extremely hazardous, while wastes with a hazard rating of 3 of 4 are of moderate or low hazard. The requirements for pre- treatment and disposal are appropriately set in accordance with the waste classification. Hazardous waste prevention and minimisation are briefly addressed, because of their importance, as is handling, transportation and storage. Document 2, Minimum Requirements for Waste Disposal by Landfill, addresses landfill classification, and the siting, investigation, design, operation and monitoring of landfill sites. In the landfill classification system, a landfill is classified in terms of waste class, size of operation, and potential for significant leachate generation, all of which influence the risk it poses to the environment. Graded requirements are then set for all aspects of landfilling, including public participation. Document 3, Minimum Requirements for the Monitoring of Water Quality at Waste Management Facilities, addresses the monitoring of water quality at and around waste disposal facilities. The Department intends extending the Waste Management Series. At the time of writing, the National Waste Management Strategy was being formulated, as a joint venture between the Department of Water Affairs & Forestry, the Department of Environment and Tourism, and DANCED. Initially, three baseline study documents were drafted by South African consultants to provide data regarding waste generation, community waste and litter, and waste disposal sites in South Africa. These will form part of the series. Further work being carried out by Danish and South African consultants, assisted by Departmental staff will generate strategy documents which will also form part of the series. Other documents envisaged for the series include Minimum Requirements for waste disposal site auditing, and training of operators and managers of waste management facilities. II PREFACE PREFACE The management of hazardous waste remains one The improvement of standards for waste disposal of the central environmental issues throughout the in South Africa will also rely on the co-operation world.

Nonetheless, the minimum requirements will also At present, regulating measures for hazardous be enforced by means of permits for waste disposal waste management in South Africa are still not on sites, the future registration of waste generators a par with international legislation. For this reason and transporters and a manifest system, in order to the department started the development of the address situations where good waste management Waste Management Series with the aim to upgrade practices have not been implemented. Costs that the standard of waste management in South Africa have in the past been externalised as social and and to provide a system whereby waste disposal environmental costs, because of the absence of can be regulated. To this end, the Minimum standards, will now be internalised in accordance Requirements for the Handling, Classification and with the “polluter pays” principle. Disposal of Hazardous Waste sets out a systematic framework for identifying a Hazardous Waste and It is accepted that improved standards will classifying it in accordance with the degree of risk inevitably result in increased costs. Consequently, that it poses.

South Africa. This must be expanded upon in the future. In addition, the minimum requirements are intended to facilitate conformity with international standards, required by future trading partners and by the Basel Convention. III PREFACE The Minimum Requirements for the Handling, Classification and Disposal of Hazardous Waste was first published in 1994. This edition has been revised in the light of use and comment. This will not be the final revision, however, and the document must be regarded as 'living'. Certain wastes may, with the development of new technologies, pose either a lesser or greater risk in the future. I expect the requirements to evolve with changing knowledge, expertise, political, social and economic circumstances in South Africa. I would therefore like to encourage you, and all other interested and affected parties, to submit written comment and input to the Department, so that your concerns can be addressed and your input included in future editions.

We evaluated the toxic effect of this mushroom on mice. Methods: We prepared extracts of fresh T. venenata and Laccaria vinaceoavellanea mushrooms collected from the environs of a village that had SUD. We randomly allocated mice into treatment groups and administered mushroom extracts at doses ranging from 500 to 3500 mg/kg and water (control) via a gavage needle. We observed mice for mortality for 7 days after a 3500 mg/kg dose and for 24 hours after doses from 500 to 3000 mg/kg. We determined biochemical markers from serum two hours after a 2000 mg/kg dose. Results: Ten mice fed T. venenata extract (3500 mg/kg) died by five hours whereas all control mice (L.

  • Poisoning Due to Raw Gyromitra Esculenta (False Morels) West of the Rockies
    CASE REPORT • OBSERVATIONS DE CAS Poisoning due to raw Gyromitra esculenta (false morels) west of the Rockies Anne M. Leathem, BSP, MSP;* Thomas J. Dorran, MD, MBA† ABSTRACT Vomiting with abdominal pain is a common presentation in the emergency department (ED). Without a careful history, unusual causes, such as toxic ingestion, may evade diagnosis. We report a case of an Asian couple who presented to the ED with vomiting and epigastric distress. They were discharged with no definite diagnosis, but on a return ED visit the following day were diag- nosed with toxic ingestion of Gyromitra esculenta, commonly known as the western false morel. The patients were admitted and treated with intravenous hydration and pyridoxine. Both patients developed mild hepatotoxicity but went on to fully recover. This case demonstrates that the west- ern false morel may cause significant toxicity and it highlights the importance of obtaining a com- plete history in patients who present with non-specific gastrointestinal symptoms. Key words: Gyromitra esculenta, false morel, gyromitrin, monomethylhydrazine, mushroom poisoning RÉSUMÉ Le service d’urgence reçoit souvent des patients qui présentent douleurs abdominales et vomisse- ments. Sans anamnèse, des causes inhabituelles, telle que l’ingestion toxique, peuvent échapper au diagnostic. Nous rapportons le cas d’un couple asiatique qui s’est présenté au service d’urgence en détresse épigastrique accompagnée de vomissements. Le couple a reçu son congé sans diagnostic précis, mais s’est présenté à nouveau le lendemain à l’urgence, où on a alors diagnostiqué une in- gestion toxique de Gyromitra esculenta, communément appelé fausse morille. Les patients ont été admis et traités par hydratation et pyridoxine intraveineuses.
