The Lechang lead/zinc (Pb/Zn) mine and Dabao Shan copper (Cu) mine are located at the north of Guangdong Province in southern China. The residual tailings were permanently stored in tailings ponds which required revegetation to reduce their impact on the environment. A greenhouse study was conducted to evaluate the feasibility of using Vetiveria zizanioides (vetiver) and Phragmities australis (...

The heterogeneity and local distribution of elements are established as a result the study nonferrous metals composition domestic wastes processing concentrate containing 20–40% copper, 40–50% brass, 20–28% zinc up to 1% aluminium. Metals mainly concentrated in granules three types: zinc-based, copper-based copper–zinc alloy, i.e., brass. phase these granule types their structure determined. Zi...

a survey on lead intoxication in lead mine workers was carried out among khanehsorme, lead miners in najafaabad and also in ab-bagh lead miners in shahreza, both located in district of esfahan, iran. the studies were carried out on 62 miners out of 82 employees in khanehsorme, 25 miners out of 27 employees in ab-bagh lead miners and 47 rural inhabitants in the surroundings of mines were selecte...

This study was undertaken in order to determine heavy metal contents in twelve (n = 12) henna brands and eleven (n = 11) kohl products. An analytical test was performed for Pb, Cd, Cu, and Zn in henna and kohl products using atomic absorption spectrophotometery. The overall mean concentrations of heavy metals in henna varied between 1.2 and 8.9 μg g(-1) for Pb; 0.8 and 18.6 μg g(-1) for Cd; 0.5...

Tobacco (Nicotiana tabacum L.) is a commercial plant. Tobacco leaves naturally accumulate and concentrate relatively high levels of heavy metals and particular cadmium in leaves. Tobacco is one of the basic agricultural products, in Ethiopia, with social and economic importance. However, there is no report in the literature on the determination of levels of heavy metals in Ethiopian tobacco lea...

Chemical forms of Zn, Ni, Cu, and Pb in municipal sewage sludge were investigated by adding humus soil to sludge and by performing sequential extraction procedures. In the final sludge mixtures, Zn and Ni were mainly found in Fe/Mn oxide-bound (F3) and organic matter/sulfide-bound (F4) forms. For Zn, exchangeable (F1), carbonate-bound (F2), and F3 forms were transformed to F4 and residual forms...

Respirable dust is everywhere (in the surface and underground mine) operations its environs. Ririwai Tin mine laden with of metallic particles Arsenic (As), Chromium (Cr), Lead (Pb) Zinc (Zn). These are also found in soil. Continuous inhalation could lead to irreversible diseases. This paper addresses control dust, using previous review prevailing concentrates. research answers questions like w...

Nine urban intertidal regions in Burrard Inlet, Vancouver, British Columbia, Canada, were sampled for plastic debris. Debris included macro and micro plastics and originated from a wide diversity of uses ranging from personal hygiene to solar cells. Debris was characterized for its polymer through standard physiochemical characteristics, then subject to a weak acid extraction to remove the meta...
