In the study, the variations of heavy metal distributions (of Cu, Mn, Pb, and Zn) during the sewage sludge composting process were investigated by sequential extraction procedures. The total content of Cu and Zn in the composted mixture increased after the composting process. Mn and Zn were mainly found in mobile fractions (exchangeable fraction (F1), carbonate fraction (F2), and Fe/Mn oxide fr...

This study was carried out to determine the proximate composition and some heavy metals (Lead, Zinc, Copper, Cadmium ) accumulation in shrimps and oysters from Buguma creek and to evaluate to what extent the changes in proximate composition and these heavy metals accumulation in shrimp (Penaeus notialis) and oyster (Crassostrea gasar) before and after smoke drying. Hot smoking method was used. ...

Due to the determination of the pollution status of fresh resources in the Egyptian territorial waters is very important for public health; this study was carried out to reveal the levels of heavy metals in the shellfish and their environment and its relation to the highly developed industrial activities in those areas. A total of 100 shellfish samples from the Rosetta, Edku, El-Maadiya, Abo-Ki...

Carbon-based aerogels have the capability of high adsorption removal copper, lead, and zinc metal ions from water systems.

Since 1971, Island Copper Mine has been operating an open-pit mine, mainly for copper on the north shore of Rupert Inlet. Rupert Inlet is the most easterly inlet of Quatsino Sound on northern Vancouver Island, British Columbia (Fig. i). The ore body was estimated to contain 250 million tons of reserves. Mining is proposed to be continued until 1996, at which time the reserves will have been dep...

The Zn-Cu battery is plagued with both the problems of Cu2+ migration into the anodic chamber as well as the problem of shape change of zinc electrodes, where both of these processes together have historically prevented this type of battery technology from being rechargeable. We herein propose using a monovalent selective cation exchange membrane (CIEM) that through X-ray diffraction experiment...

OBJECTIVE To assess the serum levels of copper, zinc, iron, and lead in patients on maintenance dialysis. METHODS This cross-sectional study performed at King Khalid University Hospital, Riyadh, Saudi Arabia between September 2011 and October 2012 included 42 patients with end stage renal disease on hemodialysis (HD), 18 patients on peritoneal dialysis (PD), and 18 normal controls. Serum copp...
