A 28-year-old female presented for evaluation of left flank pain and polyuria after having been exposed to cadmium in the jewelry manufacturing industry for approximately 3 years. This patient possessed both elevated 24-hr urinary ss2-microglobulin and elevated blood cadmium levels. Approximately 6 months after initial presentation, the patient resigned from her job due to shortness of breath, ...

The rapid urbanization and industrialization of a country tends to generate large volume industrial waste in the environment. In this sustainability era, feasibility recycling has gained attention by researchers industry practitioners. Silicomanganese (SiMn) slag is common produced ferro-alloy smelting plant Sarawak. This paper intends present review on SiMn into more sustainable construction m...

The practicability of a pyrometallurgical scheme for raw material processing is established as result the analysis methods intended to dearsenate and process gold-arsenic concentrates well equipment execution. conceptual design vacuum without forced movement dispersed in sublimator reaction zone materials proposed. In-process tests sublimation arsenic sulfides from gravity flotation received Ba...

introduction: soil has an important role in nutrient cycle and an important function in storage, refinement, and movement of nutrients for the living and non-living parts. soil pollution of heavy metals and elements is one of the common pollution impacts of human activities, especially industry. realization of distribution pattern of these elements and their anthropogenic sources is a major par...

Various natural (high arsenic bearing strata and pyrite oxidation) and anthropogenic (agricultural, coal mining, metal smelting, and refining industry) sources are involved in arsenic pollution of water. Water, soil, and biological samples (vegetables, fish, and meat) were collected from potentially arsenic affected area Hizla, Bangladesh and analyzed to find the source of arsenic contamination...

This article is stimulated by the analysis of Socolow and Thomas in the first issue of this journal. Our work showed that a lead-acid battery-powered electric vehicle (Ev) would result in more lead being discharged into the environment than a comparable car burning leaded gasoline. Five hundred thousand EVs would lead to a 20% increase in lead use in the United States, and presumably a comparab...

BACKGROUND Lead exposure is known to be harmful to the male reproductive system, including impairment of fertility. However, it is unclear whether currently existing low levels of exposure have this effect. AIMS To study retrospectively current workers in lead using industries (battery manufacture, smelting, etc), and in non-lead using control industries, in four European countries, with Time...

There is growing environmental concern with the methods of waste disposal used for handling hazardous materials in the metal finishing industry. A resulting need exists to develop and implement the best existing and potential technologies for waste minimization and resource recovery. The objectives of this study were to identify and briefly describe both existing and potential future methods fo...

The zinc protoporphyrin/haemoglobin (ZPP/Hb) ratio was measured in the field with a haematofluorometer. A significant increase in ZPP/Hb ratio with advancing age was found in 1295 men who denied any excess exposure to lead. Ninety-seven per cent of the results were below 110 mumol ZPP/mol Hb(Fe) (4.4 microgram ZPP/g Hb). The ZPP/Hb ratio was determined in a lead-exposed population of 2275 men, ...

Hydrogen has a wide range of applications and is an essential raw material in many industries such as chemical, food, metallurgical, electronics and others. It can be produced by a variety of methods, including acid and iron methods, steam-reforming production method, coal and electrolysis methods, biological processes, as well as chemical decomposition of hydrogen-containing compounds. Most of...
