The following substances and materials are listed for the purpose of Article 4 of the Protocol.1. Organohalogen compounds and compounds which may form such substances in the marine environment, excluding those which are non-toxic or which are rapidly converted in the sea into substances which are biologically harmless, provided that they do not make edible marine organisms unpalatable.2. Organosilicon compounds and compounds which may form such substances in the marine environment, excluding those which are non-toxic or which are rapidly converted in the sea into substances which are biologically harmless, provided that they do not make edible marine organisms unpalatable.3. Mercury and mercury compounds.4. Cadmium and cadmium compounds.5. Persistent plastic and other persistent synthetic materials which may materially interfere with fishing or navigation, reduce amenities, or interfere with other legitimate uses of the sea.6. Crude oil and hydrocarbons which may be derived from petroleum, and any mixtures containing any of these, taken on board for the purpose of dumping.7. High-, medium- and low-level radioactive wastes or other high-, medium- and low-level radioactive matter to be defined by the International Atomic Energy Agency.8. Acid and alkaline compounds of such composition and in such quantity that they may seriously impair the quality of sea water. The composition and quantity to be taken into consideration shall be determined by the Parties in accordance with the procedure laid down in Article 14 (3) of this Protocol.9. Materials in whatever form (e.g. solids, liquids, semi-liquids, gases, or in a living state) produced for biological and chemical warfare, other than those rapidly rendered harmless by physical, chemical or biological processes in the sea, provided that they do not:(i) make edible marine organisms unpalatable; or(ii) endanger human or animal health.B. This Annex does not apply to wastes or other materials, such as sewage sludge and dredge spoils, containing the substances referred to in paragraphs 1 to 6 above as trace contaminants. The dumping of such wastes shall be subject to the provisions of Annexes II and III as appropriate.ANNEX IIThe following wastes and other matter, the dumping of which requires special care, are listed for the purposes of Article 5.1. (i) arsenic, lead, copper, zinc, beryllium, chromium, nickel, vanadium, selenium, antimony and their compounds;(ii) cyanides and fluorides;(iii) pesticides and their by-products not covered in Annex I;(iv) synthetic organic chemicals, other than those referred to in Annex I, likely to produce harmful effects on marine organisms or to make edible marine organisms unpalatable;2. (i) acid and alkaline compounds the composition and quantity of which have not yet been determined in accordance with the procedure referred to in Annex I A (8);(ii) acid and alkaline compounds not covered by Annex I, excluding compounds to be dumped in quantities below thresholds which shall be determined by the Parties in accordance with the procedure laid down in Article 14 (3) of this Protocol.3. Containers, scrap metal and other bulky wastes liable to sink to the sea bottom which may present a serious obstacle to fishing or navigation.4. Substances which, though of a non-toxic nature may become harmful owing to the quantities in which they are dumped, or which are liable to reduce amenities seriously or to endanger human life or marine organisms or to interfere with navigation.5. Radioactive waste or other radioactive matter which will not be included in Annex I. In the issue of permits for the dumping of this matter, the Parties should take full account of the recommendations of the competent international body in this field, at present the International Atomic Energy Agency.ANNEX IIIThe factors to be considered in establishing criteria governing the issue of permits for
