Macrophytes play an important role in assessing the condition of aquatic ecosystems. The aim study was to assess effectiveness cadmium uptake by frogbit (Hydrocharis morsus-ranae) for phytoremediation examined (Cd) grown under conditions low and high fertilizer dose three levels over three- six-week exposure times. Cadmium found be influenced water reactivity, mineral nutrient abundance, time. ...

Alcoholic beverages have been classified as carcinogenic to humans. As alcoholic beverages are multicomponent mixtures containing several carcinogenic compounds, a quantitative approach is necessary to compare the risks. Fifteen known and suspected human carcinogens (acetaldehyde, acrylamide, aflatoxins, arsenic, benzene, cadmium, ethanol, ethyl carbamate, formaldehyde, furan, lead, 4-methylimi...

OBJECTIVES The aim of this study was to assess the effect of metals, with special attention of cadmium (Cd), content of the Svitava and Svratka rivers (Czech Republic) on levels of thiol compounds such as metallothioneins (MT), glutathione (GSH/GSSG), and cysteine (Cys) concentrations in chub (Leuciscus cephalus L.) liver and their use as biomarkers. DESIGN Levels of thiol compounds in fish l...

Cadmium, as a hazardous pollutant commonly present in the living environment, represents an important risk to human health due to its undesirable effects (oxidative stress, changes in activities of many enzymes, interactions with biomolecules including DNA and RNA) and consequent potential risk, making its detection very important. New and unique technological and biotechnological approaches fo...

Even though compounds of nickel, arsenic, cobalt and cadmium are carcinogenic, their mutagenic potentials are rather weak. In contrast, they exert pronounced comutagenic effects, which may be explained by disturbances of different DNA repair systems. Thus, cobalt, arsenic, nickel and cadmium interfere with base and nucleotide excision repair, even though they affect different steps of the respe...

BACKGROUND Environmental justice research suggests that inequalities in the distribution of environmental exposure to chemical pollution systematically disadvantage the lower social strata of society. The effects of these inequalities on the human exposure to pollution are however to a large extend unknown. The purpose of this study is to assess social gradients in human biomonitoring results o...

The yeast cadmium factor (YCF1) gene encodes an MgATP-energized glutathione S-conjugate transporter responsible for the vacuolar sequestration of organic compounds after their S-conjugation with glutathione. However, while YCF1 was originally isolated according to its ability to confer resistance to cadmium salts, neither its mode of interaction with Cd2+ nor the relationship between this proce...

Metals are being utilized of ways in industries and agriculture; particularly heavy metals such as Mercury, Lead, Arsenic and Cadmium constitute a significant potential threat to human health because they are associated to many adverse effects on health. Due to the increasing pollution, concentrations of various chemical compounds have increased in aquatic environments. Water contaminants have ...
