Electroplating and metalworking industries discharge large amounts of heavy metals, including copper (Cu), nickel (Ni) and zinc (Zn) ions, in their effluents have been recognized as a major problem to human health and aquatic life. Copper is highly toxic because it is non biodegradable and carcinogenic, Copper has been reported to cause neurotoxicity commonly known as “Wilson’s disease” due to ...

The goal of this study was to determine the removal efficiencies of chromium, copper, lead, nickel, and zinc from raw wastewater by chemically enhanced primary treatment (CEPT) and to attain a total suspended solids removal goal of 80%. Operating parameters and chemical doses were optimized by bench-scale tests. Locally obtained raw wastewater samples were spiked with heavy metal solutions to o...

background and aims: giardia lamblia infection is a common cause of food and water-borne diarrhea in non-sanitary communities. infections are common in children, particularly in child-care centers, backpackers, travelers, and homosexuals. zinc is necessary for the immune system functions. zinc deficiency is associated with acute diarrhea. copper is essential for the production of red blood cell...

Background: In acute lymphoblastic leukemia (ALL) the bone marrow loses its ability in the differentiation and maturation of blood cells at different stages. Zinc and copper are important co-factors for several enzymes and play an important role in maintenance of DNA integrity. Changes in serum levels of zinc and copper have been found in lymphoproliferative disorders. In the present study, the...

background: the purpose of this study was to evaluate the levels of zinc (zn), copper (cu), iron (fe) and zinc/ cop­per ratio in the serum of patients with cutaneous leishmaniasis in qom province, center of iran. methods: serum levels of zinc and copper were determined by flame atomic absorption spectrophotometer and serum iron concentration was measured by using an auto analyzer. the study gro...

soil contamination in the vicinity of the abandoned lakan lead and zinc mine was studied. the results showed that over the past decades, the environmental pollution was caused by lead, zinc tailings dam and acid mine drainage. the average of lead, zinc, cadmium, copper and nickel is 1295, 4273, 27, 185 and 92 mg/kg, respectively in the soils of tailings dam. these metals were continuously dispe...
