Heavy metal stress is one of the key factors for crop yield along with other abiotic stresses such as drought, salinity, extreme temperature and light. Due to natural and anthropogenic activities heavy metal pollution is increasing daily. Hence, it is must to know the effects of heavy metals in depth on crop growth and development ultimately yield levels. In the present work we assessed the imp...

Baseline levels of cadmium and lead were determined in muscle tissue and liver of hake (Merluccius merluccius) and red mullet (Mullus barbatus), two commercially important fish species from the eastern Adriatic. Concentrations of trace metals in liver (Cd: 6-183 microg kg(-1) w. wt. ; Pb: 39-970 microg kg(-1) w. wt.) were within the range of recently published data for the Mediterranean. In the...

The present research aims to assess the potential use of the Norway rat, Rattusnorvegicus as a bio-indicator for lead and cadmium accumulation in 10 urban zones in Tehran, the metropolitan city, Iran. During April to May 2014 we collected twenty adult Norway rats from the different predefined zones. By referring to the air pollution data collected over 15 years, the sampling areas were detected...

BACKGROUND We present herein our results regarding the accumulation of four heavy metals (copper, cadmium, lead, and zinc) in four aquatic species plants (Ceratophyllum demersum, Potamogeton pectinatus, Potamogeton lucens, Potamogeton perfoliatus) collected from the Danube River, South-Western part of Romania and their possible use as indicators of aquatic ecosystems pollution with heavy metals...

We investigated the associations of urinary concentrations of antimony, cadmium, tungsten and uranium with geographic locations and with ambient air pollution in 304 adults in the Multi-Ethnic Study of Atherosclerosis from six US cities. After adjustment for sociodemographics, body mass index, and smoking status, urinary cadmium was the highest in Winston-Salem among all study sites (the geomet...

Problem statement: Defining of correlation between toxic and essential elements in human beings is an important clinical screening procedure. Approach: The aim of this study was to determine the correlation between cadmium as toxic element and calcium as an essential element in the blood at the smokers. We have investigated 50 human blood samples of different ages and genders (age: 35-45 years ...

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. ...

Due to anthropogenic activities, heavy metals still represent a threat for various trophic levels. If aquatic animals are exposed to heavy metals we can obviously observe considerable toxicity. It is well known that an organism affected by cadmium (Cd) synthesize low molecular mass thiol compounds rich in cysteine (Cys), such as metallothioneins (MT) and glutathione (GSH/GSSG). The aim of this ...

BACKGROUND Industrial pollution may affect the heavy metal body burden of people living near industrial complexes. We determined the average concentrations of atmospheric heavy metals in areas close to and distant from industrial complexes in Korea, and the body concentrations of these heavy metals in residents living near and distant from these facilities. METHODS The atmospheric data of hea...

Protection against corrosion in the shipyard is a source of airborne particles. From October 1996 to September 1997 samples of suspended particles (1 site) and dustfall (6 sites) were collected in the vicinity of a repairs shipyard situated in the martinsćica Cove, east of the city of Rijeka, Croatia. Collected samples were analysed for lead, cadmium, iron, copper, and zinc content. Though annu...
