Mercury exposure is the second-most common cause of toxic metal poisoning. Public health concern over mercury exposure, due to contamination of fish with methylmercury and the elemental mercury content of dental amalgams, has long been a topic of political and medical debate. Although the toxicology of mercury is complex, there is evidence for antioxidant protection in the prevention of neurolo...

The impact of heavy metal toxicity on the shoot and root lengths, total protein, fiber characteristics, moisture content and nutrient composition of spinach (Spinacia oleracea) was evaluated. Plants were grown in pots containing soil and treated with different concentrations (mg/kg) of lead (Pb; 300, 400 and 500), cadmium (Cd; 0.5, 1 and 1.5) and zinc (Zn; 250, 500, and 700) as well as mixtures...

Trace heavy metals, such as arsenic, cadmium, lead, chromium, nickel, and mercury, are important environmental pollutants, particularly in areas with high anthropogenic pressure. In addition to these metals, copper, manganese, iron, and zinc are also important trace micronutrients. The presence of trace heavy metals in the atmosphere, soil, and water can cause serious problems to all organisms,...

Oxidative stress is induced by a wide range of environmental factors including heavy metals stress. Therefore, antioxidant resistance mechanisms may provide a strategy to enhance metal tolerance, and processes underlying antioxidant responses to metal stress must be clearly understood. In the present study, the effects of heavy metals generating antioxidative defense systems (i.e. superoxide di...

The present study is focused on the importance of SNP, a NO donor, as Cd stress modulator on seedlings of cabbage. The exogenously applied Cd induced stress in cabbage seedlings to explore the protective role of SNP. 21-day-old seedlings were grown in Hoagland solution and Cd at 0.5 and 0.7 mM concentration with and without SNP. The biophysical and biochemical parameters were analyzed. Cd exhib...

Coastal areas including the estuaries of Persian Gulf are sensitive and fragile areas of aquatic ecosystems in Iran that are severely affected by pollution from urbanization, industrialization, and maritime activity. Despite numerous studies on the status of pollution, especially heavy metals in these areas, comprehensive and systematic studies on this subject have not been conducted. Therefore...

With the rapid economic development in recent years, China is facing a great challenge due to heavy metal pollution. The heavy metals may enter the human body through ingestion of aqua products to cause great health risks. In the present study, the inhibitory effects of luteolin on the combined toxicity of multi-heavy metals (including zinc, manganese, lead, copper, cadmium, mercury, chromium a...

Measuring heavy metal levels in the urine is an accepted method for assessing the presence of a heavy metal burden in an individual. Random samples (without a flushing agent) are excellent for showing current exposures, as they reflect the level of heavy metals in the bloodstream during the hours immediately before bladder voiding. Samples taken after using a heavy metal mobilizing agent are a ...
