Crayfish, carp, and crab threaten the consumer’s health due to enrichment of toxic elements. The concentration elements (As, Cr, Cd, Pb) in these aquatics was less investigated simultaneously situ. In this study, from same site Hanchuan, Hubei Province, China were measured by ICP-MS assess four them risk consumer. results showed that concentrations muscle lower than those hepatopancreas/ liver,...

The concentrations of six non–dioxin-like polychlorinated biphenyls (NDL-PCBs) were measured using the quick, easy, cheap, effective, rugged, and safe (QuEChERS) by gas chromatography (GC) coupled with triple-quadrupole (QqQ) tandem mass spectrometry (MS/MS) method in cream ice offered Tehran (Iran). results showed limits detection, limit quantification recovery for PCB analytes ranges 0.04–0.1...

An assessment was carried out at a UK integrated steelworks to investigate the exposure of workers via inhalation to dioxins [polychlorinated dibenzo-p-dioxins (PCDD/F)], polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAH) including benzo[a]pyrene (B[a]P). Investigations focused on a basic oxygen steelmaking (BOS) plant and an iron ore sintering plant. The highest conce...

Introduction: It is estimated that by 2020, non communicable diseases will account for approximately twothird of all diseases that are often related to life style and nutrition. This study was conducted to assess Food pattern and anthropometric indices of students in Kerman University of Medical Sciences. Methods: In this cross-sectional study, 375 students (225 females, 150 males) with mean ag...

The World Health Organization recommends assessing human exposure to contaminants on a regular basis. In order to assess the current dietary exposure of the Belgian adult population to PCDD/Fs and dioxin-like PCBs and to update exposure estimates of 2000-2001, a total diet study was designed. The mean dietary intake of PCDD/Fs and dioxin-like PCBs in the Belgian adult population in 2008 was est...

The distribution and dynamics of microcystins in various organs of the phytoplanktivorous bighead carp were studied monthly in Lake Taihu, which is dominated by toxic cyanobacteria. There was a good agreement between LC-MS and HPLC-UV determinations. Average recoveries of spiked fish samples were 63% for MC-RR and 71% for MC-LR. The highest MC contents in intestine, liver, kidney and spleen wer...

-1This study reports about how to integrate the environmental contaminant perchlorate into the QuPPe multiresidue method for the analysis of polar pesticides. Perchlorate, along with a number of polar pesticides, was extracted with acidified methanol. The extracts were filtered and subjected to liquid chromatography-triple quadrupole mass spectrometry (LC-MS/MS). 18O-labeled perchlorate was use...

This study targets the lesser-known ingredients of smokeless tobacco products, i.e., the toxic metals, in Indian brands. The metals selected in the study included lead (Pb), cadmium (Cd), arsenic (As), copper (Cu), mercury (Hg), and selenium (Se). The differential pulse anodic stripping voltammetry (DPASV) technique was used for estimating the metals Pb, Cd, and Cu; square wave voltammetry for ...
