Although nutrient-rich manure biochars are expected to be an effective heavy metal stabilizer in agricultural and contaminated soils, systematic studies are lacking to predict the influence of manure variety and pyrolysis temperature on metal-binding potentials. In this study, biochars produced from five manure varieties (dairy, paved feedlot, swine solids, poultry litter, and turkey litter) at...

The purpose of this study was to determine the water-soluble concentrations hazardous heavy metals in Zhengzhou city road dust order quantify ecological and health risks. It discovered that Cu (328.3 µg/l), Zn (191.7 µg/l) were with highest concentrations, whereas Hg (0.24 Cd (2.61 Pb (3.57 lowest metals. Ecological risk assessment (RI) indicated most abundant contaminant Hg, followed by Cd, wh...

In this study, heavy metals (Hg,Cd,Pb,Cu,Zn) and metallothionein (MT) biosynthesis were measured in blood of green sea turtles (Chelonia mydas) nesting on the northern coast of the Sea of Oman. Heavy metals concentrations in the sea water, the sediments, the blood samples ranged between 0.02-8.43 μg/l, 0.06-10.32 μg/l, and 0.16-36.78μg/g (ww), respectively.The highest concentration...

Airborne particulate matter (PM10 ) was collected from the atmosphere of the city of Isfahan. The concentration of heavy metals and anions associated with airborne particulate matter were determined using atomic absorption spectrometric and ion chromatographic techniques. A comparison was made between the variation in the concentration of PM10 and that for heavy metals and...

abstract         heavy metals have raised one of the most important problems in ecology and organisms life especially human being and animals. a variety of indicators including tissues of fish, birds and sediment have been used recently to measure the aquatic pollution with heavy metals. the aim of this study was to search the published articles in iran and the world on the role of helminthic p...

Uptake of metals in rice has been reported in the context of human health and nutrition. In particular, low levels of heavy metals like Fe, Zn, Cu and Mn in rice and other cereals are considered to be desirable for good preventive nutrition. According to FAO and WHO, the daily recommended intake of Fe, Zn, Cu, and Mn for an average adult is 15, 12, 1.5–3.0 mg and 2–5 mg respectively. Zn deficie...

background foods are enriched with variety of chemical elements. some of these elements are necessary for human health. these elements enter in liquid, the cells and other organs, certain amount of these elements are essential for body organs to work properly. objectives this research was conducted to compare the level of lead and cadmium contamination in garlic species planted in ramhormoz and...
