Europe issued 18 black list substances daughter directives. These include an environmental quality standard (EQS) that the surface water must meet. Regarding the other dangerous substances, the Member States were compelled to draw up reduction programs. The set-up of the reduction programs did not occur until many years later. 

Mercury and its compounds are included in the "Black List of all the international conventions such as the Oslo, Paris, and Barcelona Conventions and the EEC Directive on the discharge of dangerous substances, the main aim of which is to prevent aquatic pollution. One of the common objectives of these control measures is to eliminate, to prohibit, or to strictly control the discharge of all black list substances into natural waters.

Due to the environmental impact of pesticides, several priority lists have been published to help protect the quality of drinking and surface waters. Table 4 lists the different pesticides from the 76/464/EC Directive (i. e., the so-called black list [168, 171-174]). Following the three general parameters (toxicity, persistence, and input) for selecting the priority list of pollutants in the United Kingdom, a red-list of substances that include several pesticides, most of them common to the EC list, was established.

For substances for which comparative dissolution data are not sufficient proof of efficacy ( black list ) Annexure A (MCC circular 14/95), conclusive comparative bioavciilability data in 12 subjects or in 20 subjects for sustained release products versus the SA Innovator or the Innovator in one of the following countries ... 

Part XVIIIA of the Drug Tariff for England and Wales and Part XIA of the Northern Ireland Drug Tariff lists those drugs and other substances not to be prescribed on an NHS prescription form. These sections were colloquially referred to as the black list, although this is a term that is not used much nowadays. Similar information for Scotland is contained in Schedule 10 to the NHS (General Medical Services) Regulations 1992. 

On the former black list of Directive 74/464/CE, there were 132 substances, including the following OPPs azinphos ethyl, azinphos methyl, coumaphos, demeton, dichlorvos, disulfoton, fenitrothion, fenthion, malathion, methamidophos, mevinphos, omethoate, parathion, dimethoate, oxydemeton methyl, phoxim, trichlorfon, and triazophos.

Cu, Ni, Co, Cr, Fe, or Al, even in traces, must be absent when conducting a direct titration of the other metals listed above if the metal ion to be titrated does not react with the cyanide ion or with triethanolamine, these substances can be used as masking reagents. It has been stated that the addition of 0.5-1 mL of 0.001 M o-phenanthroline prior to the EDTA titration eliminates the blocking effect of these metals with solochrome black and also with xylenol orange (see below). 

Requirements for labelling of containers for supply may differ from those for conveyance. Key features of a supply label are to identify the substance (the chemical name in most cases) and any hazards and safety precautions. Supply labels are black on yellow/orange. In Europe the classification, packaging and labelling of dangerous substances is covered by Directive 67/548/EEC as amended. This requires labels to identily appropriate risk and safety phrases (Tables 14.3 and 14.4) depending upon product properties. A substance is considered dangerous if in Part 1A of an approved list or if it exhibits hazardous properties as defined in Schedule 1 for supply, or Schedule 2 for conveyance as shown in Tables 14.5 and 14.6. Substances not tested should be labelled Caution - substance not yet fully tested . Criteria for risk phrases are provided, e.g. as in Table 14.7 for toxic compounds. 

Explosive Compositions are mixtures of explosive and non-explosive substances. They are listed in this Encycl as individual items such.e.s Amatols, Ammonals, Ammonium Nitrate Blasting Explosives, Black Powder, Compositions A, B, C D, Cyclonites, Dynamites and as Explosive Compositions listed-further in this Vol. (See also Composite Propellants described in Vol 3, pp C464 to C473)... 

A) Substances based on inorganic nitrates and not contg chlorates, perchlorates, NG, NC, aromatic nitrocompds can be destroyed either by drowning them in water or by burning in the air. Examples of such expls are some Ammonals, such as listed in Vol 1, p A289, Table, and Black Powder (See Vol 2, p B177-R)...
