Hexavalent chromium wastes need to be chemically reduced to trivalent chrome in the shop’s treatment plant. This necessitates the use of expensive chemicals such as sulfur dioxide, sodium metabisulfite or sodium borohydride. Also considerable hazardous sludge is generated during the neutralization step of the treatment process due to the high chromium concentration of the plating solutions. Haz...

This study illustrates the process of removal of chromium from chrome tanning waste-water by fly ash which was drive from chrome shaving dust. This experiment was carried out in a batch process with laboratory prepared adsorbent samples and chrome tanning water collected from local tanneries. The influence of various factors likes adsorbent doses, contact time, and initial concentration of chro...

This work investigates the upalytics.com library for Chrome and Firefox extensions, which performs real time tracking of users on all sites they visit. The code is bundled with free extensions in the official extension stores, exfiltrating browsing history as a feature. Within the top 7,000 Chrome extensions, the library is used 42 times with over 8 million installations, the most widely used o...

During the past several years, waste produced by the electroplating industry has attracted attention due to the level of pollutants found in the waste stream, the difficulty associated with treatment, and the cost of waste disposal. EPA has enacted regulations to control the discharge from plating facilities and estimates that 140 million lb of metal pollutants will be prevented from being disc...

pH/Laccase responsive microcapsules with tailorable shells were prepared by the layer-by-layer deposition of sodium lignosulfonate and chitosan for protecting photosensitive avermectin.

Ulceration of the skin due to contact with hexavalent chromium was first described by Cummings in 1827. One hundred years later, in 1928, Blair published a study of 12 cases of skin and nasal ulceration at a time when chrome plating had become commercially successful. Formal regulations to protect workers heath were introduced for the first time in the UK in 1931, when the risks of occupational...
