This study examines the presence of heavy metals in different types of leather finished goods. Various leather items like gloves, shoe soles and leather pieces for jackets were tested using Atomic Absorption Spectrophotometry and their toxic effects in our environment are discussed. Cadmium, lead and chromium are the most common heavy metals present in leather finished goods and are a cause for concern. Many countries in Europe and America have banned or limited their use in leather processing. This study reveals that the levels of heavy metals in most of the leather goods manufactured by different companies in Pakistan are within permissible limits. However, in some of the samples tested in this study, the amounts of cadmium, lead and chromium are considerably high which requires special attention from all stakeholders to bring it down to acceptable level. Failing to do so will be detrimental for export of these leather goods to Europe and America
