Fast hexavalent chromium (Cr(VI)) determination is important for environmental risk and health-related considerations. We used a microbial fuel cell-based biosensor inoculated with a facultatively anaerobic, Cr(VI)-reducing, and exoelectrogenic Ochrobactrum anthropi YC152 to determine the Cr(VI) concentration in water. The results indicated that O. anthropi YC152 exhibited high adaptability to ...

BACKGROUND Occupational Cancer Monitoring (OCCAM) is an Italian organization that monitors occupational cancers, by area and industrial sector, by retrieving cases and employment history from official databases. OCCAM previously estimated a relative risk (RR) of lung cancer of about 1.32 among "metal treatment" workers in Lombardy, northern Italy, potentially exposed to chrome and nickel. In th...

The automotive industry is a pioneer in solutions that meet market expectations. However, the industry, some less environmentally friendly technologies are still used, such as electroplating. Due to legislative restrictions several countries, thin coatings made vacuum have been replacing traditionally by electroplating, mainly decorative terms. This work more focused on use of these for optical...

Two series of electroplating experiments have been carried out onto mild steel substrate at 65 °C in several electroplating baths under different constant applied current densities. The objectives of the first series of experiments are to understand the behavior of electrodeposition of Cu and Sn in the several alkaline cyanide baths and to explore the electroplating conditions which are appropr...

A study was carried out to investigate the effects of municipal wastewater treatments on physical and chemical properties of saline soil. Recently, the amounts of wastewater are sharply increasing and the kinds of pollutants are also varied as the world wide industry is being developed incessantly. Soil samplings of 0-20 cm depth were from Segzi plain in Isfahan province (the center of Iran). T...

Copper electrodeposition in high-aspect-ratio through-holes micromachined by deep reactive ion etching is one of the most essential processes for fabricating through-wafer interconnects, which will be used in developing future generation high-speed, compact 3D microelectronic devices. Although copper electrodeposition is a well-established process, completely void-free electroplating in very de...

Leather industries are key contributors in the economy of many developing countries, but unfortunately they are facing serious challenges from the public and governments due to the associated environmental pollution. There is a public outcry against the industry due to the discharge of potentially toxic wastewater having alkaline pH, dark brown colour, unpleasant odour, high biological and chem...

The coffee industry uses large amount of water during various stages of coffee production. Coffee processed by wet method generates large volume of high strength wastewater rich in COD and nutrients hence to comply with stringent environmental regulations and for restoration of safe environment, it has become imperative to find less costly and easily adaptable treatment technology. Coffee pulpi...

This chapter provides a general overview of physical–chemical wastewater remediation systems in the food industry. Water reuse systems are becoming more and more interesting and promising technologies, depending on merely quantitative estimations, physical and chemical features of pollutants and the variability of these characteristics, week after week. Different systems are available for the f...
