In this work, pristine CeO2 and Zn-doped CeO2 nanorods were prepared through facile hydrothermal process and characterized. The Zn-dopied CeO2 was first used for dispersive solid phase micro extraction (d-SPµE) of lead in water and food. The conditions affecting d-SPµE of lead were optimized. They were pH, adsorption/elution contact time, and eluent type/volume/concentration, interfering ion effects and sample volume.

A rapid, sensitive, accurate and precise micro solid phase extraction method for the determination of Pb (II) in Fish sample by ionic imprinted polymer was developed on the surface of mesoporous silica and based on graphene oxide nanobeads. Extraction parameters were optimized using Box-Behnken design to achieve the twin objectives of quantitative determination and removal of Pb (II).

Despite the nutritional importance of seafood, these marine organisms can bioaccumulate environmentally persistent and potentially toxic chemicals, such as arsenic (As) and its species. In this work, the influence of culinary treatments commonly performed before seafood consumption on the bioavailability of As and As species was evaluated.

Imitation milks based on vegetables have become relevant in recent years as a substitute for cow´s milk. Total and inorganic content of arsenic (As) determination in food is of utmost importance due to toxicological concerns.

Potentially Toxic Elements (PTEs) in foods are a threat to global health. This study investigated concentrations of selected PTEs; cadmium, chromium, nickel and lead in fish and cultivated vegetables from and along the dams, respectively. Totally, 84 samples; 60 Tilapia (Oreochromis niloticus), 12 Okra (Abelmoschus esculentus) and 12 Bitter leaf (Vernonia amygdalina) obtained from six dams in Southwestern Nigeria were digested using aqua-regia.

With emerging food safety concerns, our study aimed to assess the effect of different levels of soil As and Cd on the accumulation/translocation of toxic (As, Cd) and essential elements (Zn, Fe, Cu, and Mn) by ‘‘red raw samba’’, a hybrid rice variety (short grain; red pericarp; 3.5 months).

Edible oil-based switchable-hydrophilicity solvent liquid–liquid microextraction (EO-SHS-LLME) was used prior to the determination of lead as its metal chelate with ammonium pyrrolidine dithiocarbamate (APDC) by flame-atomic absorption spectrometry.

In this study, an efficient and simple analytical approach for the preconcentration and extraction of cadmium from sunflower oil, olive oil and hazelnut oil samples using environmentally friendly, easy and efficient vortex assisted reverse phase spray-based fine droplet formation liquid phase microextraction (VA-RP-SFDF-LPME) prior to flame atomic absorption spectrometry (FAAS) measurement was proposed.

High concentrations of total arsenic (As) has been found in Agaricus blazei Murrill and Tricholoma matsutake samples. It is important to study the As species in A. blazei and T. matsutake for accurate health risk assessment. Total As was measured by inductively coupled plasma-mass spectrometry (ICP-MS).

This study evaluated toxic metal concentration in raw milk and related potential health risks. 100 raw milk samples and 30 water samples consumed by cows were gathered from 10 dairy farms in Behbahan county, and Pb and Cd were analyzed by Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES). In raw milk samples, mean Pb and Cd levels were 0.55±0.09 and 0.0031±0.0004 mg/l, respectively.

Detrimental health effects caused by the intake of food contaminated with heavy metals have drawn concerns on effective monitoring using rapid and benign methods.

Trace metals such as lead and mercury can be present in beverages by contamination during production and storage processes, or by the use of hops and brewing grains that may be contaminated with trace metals. Since these metals are harmful to human health, their presence is strictly controlled by regulatory agencies.

A simple, efficient, and environmentally friendly method for the determination of pyrethroids and cadmium in drink samples was developed by successive homogeneous liquid-liquid microextraction (SHLLME) based on switchable hydrophilicity solve

In order to assess the health risks associated with the consumption of Sardina pilchardus (Walbaum, 1792) and to study the spatiotemporal dynamics of three potentially toxic metals, lead (Pb), cadmium (Cd) and mercury (Hg) concentrations were measured in the muscle and the liver of 872 specimens of sardine sampled between October 2017 and September 2018 along the Algerian coast at 3 sites (Algiers, Dellys and Bejaia) subject to high pollution pressure.

To estimate the mean dietary exposure to total As (tAs) and some arsenic species [inorganic arsenic (iAs), methylarsonic acid (MMAs) and dimethylarsinic acid (DMAs), and arsenobetaine (AsB)] across the entire Japanese population (≥1 year old), a national total diet study (TDS) based on composite sample with a market-basket approach was conducted in Japan from 10 regions throughout Japan in 2019.
