This publication describes everyday products that contain added mercury and that contribute to mercury releases into the environment and the ocean. The major product groups in which mercury is added intentionally are thermometers, fluorescent light bulbs, some battery types, some traditional types of electrical switches, some skin lightening creams, traditional manometers and pressure gauges. In addition, the guideline presents the requirements established in Article 4 of the Minamata Convention on the gradual elimination of the manufacture, import, use and global trade of certain products with added mercury.
