Cadmium (Cd) causes pervasive harm on human health as a poisonous heavy metal. This study proposed a surface-enhanced Raman spectroscopy (SERS) approach using sodium alginate (SA) as green reductant in combination with edge enrichment and chemometrics to build label-free Cd quantitative models. The silver nanoparticles synthesized by SA had good dispersion and enhancement factor (3.48 × 105).

Soil health plays a vital role to sustain plants, animals, and humans (Lehmann et al., 2020).

In the present study, lead, zinc and copper concentrations in the feathers of Common kestrel (Falco tinnunculus), Eurasian magpie (Pica pica), Common buzzard (Buteo buteo), Crested lark (Galerida cristata), Eurasian hoopoe (Upupa epops), Little owl (Athene noctua), Long-eared owl (Asio otus), Eurasian eagle-owl (Bubo bubo) and Long-legged buzzard (Buteo rufinus) from Sabzevar and Neghab, Khorasan Razavi of Iran w

Lead (Pb) is an environmental neurotoxin that can lead to toxicity. It has shown that tissues can be exposed to oxidative stress in lead poisoning. Since silymarin is a natural agent with antioxidant effects, this study aimed to investigate the antioxidant and chelation effects of silibinin and nano-silibinin on the oxidative stress status in lead-poisoned rats. Sixty male Wistar rats randomly divided into ten groups (n=6).

The objective of this study was to evaluate the physiological characteristics and rhizofiltration potential of Talinum paniculatum cuttings subjected to lead (Pb) and manganese (Mn) excess. The cuttings excised from T. paniculatum were transferred to a nutrient solution, to which different concentrations of Pb (0, 10, 50, 100, and 200 mg L−1) and Mn (0, 10, 50, 100, and 150 mg L−1) were added.

Abstract Heavy metals (HMs), among the components of air pollution that is one of the utmost critical concerns our world has faced, are one of the biggest threats to living organisms. The plants, as a biomonitor, offer the most effective solution in tracking the change of HM concentration on earth and taking them under control.

Background and aims Chelates like ethylenediaminetetraacetic acid (EDTA) have frequently been applied for facilitating lead (Pb) phytoextraction and cleaning contaminated soils but without detailed report regarding the internal mechanisms happening in plants in response to EDTA addition.

Journal of the Science of Food and Agriculture, EarlyView. BACKGROUND Cadmium is a non-biodegradable heavy metal with a long biological half-life.

Background Non-Hispanic Asians (NHA) in USA have been reported with higher arsenic (As), lead (Pb), cadmium (Cd), mercury (Hg) and their specific species levels, comparing with non-NHA.

Aim:To present the content, data quality, and research potential of the West Jutland Tele-Electrocardiogram Registry (WEJU-tECG).Methods:Danish patients reporting symptoms indicating heart disease in the prehospital setting are subjected to a 12-lead tele-electrocardiogram (ECG) in the ambulance, which is digitally sent to a local tele-centre.

This multi-institutional study assessed the efficacy of Enterococcus faecium NRRL B-2354 as a non-pathogenic Salmonella surrogate for thermal processing of nonfat dry milk powder, peanut butter, almond meal, wheat flour, ground black pepper, and date paste. Each product was analyzed by two laboratories (five independent laboratories total), with the lead laboratory inoculating (E. faecium or a five-strain Salmonella enterica cocktail of S.

Abstract Insects and fungal pathogens pose constant problems to public health and agriculture, especially in resource-limited parts of the world; and the use of chemical pesticides continues to be the main methods for the control of these organisms. Photorhabdus spp.

In this study, topsoil and soil profiles were collected from typical karst areas in central Guizhou to investigate the accumulation and bioavailability of As in cultivated soils. The parent material of the investigated soil is carbonate rock, but there is strong heterogeneity in the As concentrations of soils developed in the Permian and Triassic, with average concentrations of 18.31 and 40.35 mg/kg, respectively.

Arsenobetaine (AsB) is a primary arsenic (As) compound found in marine organisms. However, in mammals, the metabolic mechanism of AsB remains indistinct.

Sumoylation is a posttranslational modification (PTM) in which SUMO (small ubiquitin-like modifier) is covalently conjugated to protein substrates via a range of enzymes. SUMO E3 ligase SIZ1 is involved in mediating several essential or nonessential element-responsive SUMO conjugations in Arabidopsis. However, whether SIZ1 is involved in the cadmium (Cd) response remains to be identified. In this study, we found that SIZ1 positively regulates plant Cd tolerance.

Journal of the Science of Food and Agriculture, Accepted Article. Dietary fiber (DF) is a carbohydrate from the edible part of plants and has the functions of promoting gastrointestinal motility, regulating gut microbiota (GM), and improving health. Lead (Pb) is a non-essential toxic heavy metal that can accumulate in the environment over time and enter the body through the respiratory tract, skin, and gastrointestinal tract.

by Adam Wilkinson, Ellen Ariel, Jason van de Merwe, Jon Brodie Toxic metal exposure is a threat to green sea turtles (Chelonia mydas) inhabiting and foraging in coastal seagrass meadows and are of particular concern in local bays of the Great Barrier Reef (GBR), as numerous sources of metal contaminants are located within the region. Seagrass species tend to bioaccumulate metals at concentrations greater than that detected in the surrounding environment.

Long term low dose exposure of arsenic has been reported to lead various cells proliferation and malignant transformation. GLUT1, as the key transporter of glucose, has been reported to have association with rapid proliferation of various cells or tumor cells. In our study, we found that low dose exposure to arsenic trioxide (0.1μmol/L As2O3) could induce an increase in glucose uptake and promote cell viability and DNA synthesis.

Screening for superior cadmium (Cd) phytoremediation resources and uncovering the mechanisms of plant response to Cd are important for effective phytoremediation of Cd-polluted soils. In this study, the characteristics of Coreopsis grandiflora related to Cd tolerance and accumulation were analyzed to evaluate its Cd phytoremediation potential.

Contamination of agricultural products by cadmium (Cd) is a global health problem, causing chronic abnormalities. The consumption of rice, the most-consumed foods, is an important exposure route of Cd to human body. Chloride (Cl-) is reported to increase Cd uptake by rice; however, the effect on Cd uptake and accumulation by rice in the presence of lime is not clear.

Cadmium (Cd) is one of the most toxic environmental pollutants. Quercetin (Que) is a kind of natural flavonoid with neuroprotective, antioxidant, and free-radical scavenging pharmacological activities. However, whether Que has the protective effect of on Cd-induced rat hepatocyte injury is unclear. This study aimed to determine the protective effect of Que on Cd-induced hepatotoxicity in vivo and in vitro.

Excessive intake of arsenic (As) and fluoride (F), which are present in underground drinking water, have adverse effects on human health, and especially on the male reproductive system. In this regard, it's critical to figure out how As and F affect Leydig and Sertoli cells, which are key cells in the male reproductive system.

Cadmium (Cd) is a widely distributed heavy metal that is toxic to plants and humans. Although silicon (Si) has been reported to reduce Cd accumulation and toxicity in plants, evidence on the functions of Si and its mechanisms in the possible alleviation of soybean are limited. Therefore, a controlled experiment was conducted to investigate the impacts and mechanisms of Si on Cd retention in soybean.

Municipal solid waste incineration fly ash (FA) contains high contents of salts and high concentrations of heavy metals, which makes FA disposal extremely difficult. However, heavy metal elements could potentially be separated from FA during thermal treatment process to make it possible to be recycled. This work aims to study the volatilization of heavy metals in FA treated by molten salt method.
