Toxicological & Environmental Chemistry

The Research Publications track research that is published across national and international peer-reviewed journals. The most recent articles are available ahead of print and searchable by Journal Title, Subject, USDA Grant Funding Agencies or FDA Grant Funding Agencies. The research publications are tracked across five subject areas: Bacterial Pathogens, Chemical Contaminants, Natural Toxins, Parasites, and Viruses.

To evaluate the effects of exogenous selenium on cadmium tolerance and accumulation in two varieties of cucumber, pot experiments with cadmium at 10 mg/kg soil were conducted. Plant biomass, cadmium bioaccumulation, cadmium speciation, and antioxidative enzyme activity, including superoxide dismutase, catalase, peroxidase, and ascorbate peroxidase were determined. Exogenous selenium (1 mg/L for...

Festuca rubra L. plants are pseudometallophytes colonizing abandoned Pb/Zn mine areas, successfully employed in phytostabilization. To study the contribution of low-molecular weight organic acids to metal tolerance, F. rubra plants were grown for three months in hydroponics with Cd (1.8, 18 and 36 µmol L−1), Pb (50, 250 and 500 µmol L−1) and Zn (0.3, 3 and 6 mmol L−1), separately, and in ternary...

The methods conventionally used for the extraction of organic pollutants in different environmental matrices are not suitable for measuring low concentrations of polycyclic aromatic hydrocarbons bioaccumulated in terrestrial snails that are both indicator of soil quality and a food item of various consumers including human being. A protocol, adapted from the QuEChERS method, originally designed...

Starting from the suspicion that the medicinal herbs may contain traces of pesticides and taking into account the risks of patients being exposed to contaminated products, the aim of this research was to evaluate the pesticide residues and the degree of their transfer (%) in three types of preparations (infusion, decoctionand cold maceration), for four medicinal plant species very often used in...

A large number of pesticides used in agricultural practice has been characterized or suspected to be Endocrine Disruptors, with dietary intake to be the major route of consumer’s exposure. In the present study the safety to consumer after the consumption of pome fruits and fruiting vegetables originated from the area of Thessaly, Central Greece was assessed. Objective samplings of 110 samples...

Glucomannan is a highly branched polysaccharide with glycosidic linkages, constituted of mannoses and glucoses. In recent years, its usefulness due to its immunological, antioxidant and antimutagenic activity has been recognized. The aim of the study was to determine the antigenotoxic ability of glucomannan extracted from Candida utilis orally administered (100–700 mg/kg) to mice, which...

Acrylamide is a highly soluble and widely produced industrial chemical that has been shown to pose numerous health hazards. This study aimed to assess the effects of acrylamide on the cytotoxicity and oxidative damage in embryonic fibroblast cells (BALB/c 3T3) and to measure protective roles of the natural antioxidants vitamin C and curcumin. Embryonic fibroblast cells were exposed to acrylamide...

The protective effects of vitamin E (45, 150, and 500 mg/kg/d) against reproductive toxicity induced in male Kunming mice by intragastric administration of 120 mg/kg/d bisphenol A was investigated. After two weeks, relative organ weights, sperm counts, sperm abnormality rates and serum testosterone concentrations were determined. Epididymal sperm counts were significantly decreased, sperm...
