Heavy metals are ubiquitous in trace concentrations in soils and the plants grown in these soils face the heavy metal stress, and causes changes in production of secondary metabolites. High levels of heavy metal ...
The determination of heavy metals in soil was disturbed by matrix elements or spectral interferences . In this study, this problem was solved by internal standard method .
Results indicated that heavy metals concentration were higher in industrial area, than from the semi-industrial and non-industrial areas but well within the prescribed permissible limit. Among the five heavy metals analyzed in the milk samples, cadmium was higher than the other elements viz., lead, mercury, nickel and arsenic.
The expired milk samples showed enhanced levels of Fe, Zn, Cr and Pb by a factor of 1.2-1.6 on average. The results of the metal contents were compared with those for …
In this study, the concentrations of selected heavy metals including Pb, Zn, Cr, Ni, Cu, As, and Cd in different brands of canned vegetables and fruits including canned tomato sauce (ketchup), canned green beans, canned whole carrots, and canned juice (pineapple) imported to Jordanian market were determined by acid digestion and atomic absorption …
The relevant regulatory agencies should establish and implement more precisely the permitted levels of cadmium, nickel, cobalt, and copper in milk, and each unit that processes milk should be...
Two of these are focused on the modification by ex-situ Sb(III) electrodeposition and the use of complexing agents for the determination of the target metal ions [78, 79], and will be discussed later in the text in a dedicated section (i.e., Section 3 – Metal ions determination by adsorptive stripping voltammetry employing complexing agents).
The spike recoveries for As, Cd, Hg, and Pb in all spiked samples met the AOAC Standard Method Performance Requirements (SMPR®) for Determination of Heavy Metals in a Variety of Cannabis and Cannabis-Derived Products (SMPR 2020.001) of 60-115% for low-level spike and 80-115% for mid- and high-level spikes.
Comprehensive analysis of the low carbon content of the metal elements in plant samples (Zn, Cu, Pb, Fe, Cd, Cr) of the measurement, can be aqua-regia-HClO 4 pretreatment method, and for comparing the carbon content high plant samples should be used as a dry ashing pretreatment method. That is, different pretreatment methods for the ...
Health risks associated with these metal intakes were evaluated in terms of dietary intake and target hazard quotients (THQs). The THQ values for individual metals were below 1 (except As for some species), suggesting that people would not experience significant health hazards if they ingest a single metal from one species of fish and/or vegetable.
The determination of heavy metals in the milk samples was performed through a digestion procedure, according to the UNI EN 13805:2002. About 0.5 mL of the milk …

Pea metallothioneins (PMTs) can capture toxic metal ions a) Condensing to form binding pockets b) Ketones used to cross-link alkoxyamine-substituted polymers [159]
Concentrations of metals (aluminium, cadmium, lead and mercury) were determined from canned tuna commercialized in Canada and India, by inductively coupled plasma - optical emission spectrometer (ICP-OES) and direct mercury analyzer (DMA 80). Higher concentration of Al (1.806 to 3.161 µg/g) and Hg (0.60 to 0.62 µg/g) were found in tuna …
Heavy metal is a broad term that describes a group of naturally occurring metallic elements of high molecular weight and density compared to water.[1] At low concentrations, certain heavy metals, such as iron, zinc, copper, and manganese, are essential for human survival but can become toxic agents at higher concentrations. Other heavy metals, such as …
