Trace element contamination in aquatic ecosystems is one of the most important concerning of environmental health. Submerged aquatic plants can be used for the removal of Trace elements. The aim of this study was to investigate how Ceratophyllum demersum could affect on wastewater quality for recycling the wastewater to reuse for other purposes in agriculture and industrial fields. In this surv...

The effect of heating on the refractive index (RI) and trace elemental compositions of glass was investigated in order to develop an accurate discrimination method of glass fragments exposed to the high temperature of fire on illegal entrance into a crime scene for robbery. Fragments taken from 5 different sheet glasses were subjected to RI measurement and analysis of trace elements using ICP-M...

BACKGROUND The analysis of mineral elements composition was determined in three wild edible herbs (Cichorium intybus L., Sonchus asper L. and Borago officinalis) collected in seven different sampling sites which were characterized by different pollution grade. The detection of mineral elements (Ca, K, Mg and Na), micronutrients (Cu, Fe, Li, Mn and Zn) and heavy metals (As, Cd, Hg, Ni and Pb) wa...

Soil profiles were collected in three salt marshes with different plant species (i.e. Phragmites australis, Tamarix chinensis and Suaeda salsa) in the Yellow River Delta (YRD) of China during three seasons (summer and fall of 2007 and the following spring of 2008) after the flow-sediment regulation regime. Total elemental contents of As, Cd, Cu, Pb and Zn were determined using inductively coupl...

The regional management of trace elements in soils requires understanding the interaction between the natural system and human socio-economic activities. In this study, a social-ecological patterns of heavy metals (SEPHM) approach was proposed to identify the heavy metal concentration patterns and processes in different ecoregions of Beijing (China) based on a self-organizing map (SOM). Potenti...

The main scope of this paper is first of all to verify the efficiency of the flame atomic absorption spectroscopy (FAAS) method for analysis of some trace elements in extracts of fractionation analysis of the gravitation dust sediments. Investigation was oriented to the analysis of some markedly toxic trace elements in the extracts of gravitation dust sediments as well as on efficiency evaluati...

The aim of the study is to evaluate the blood lead (Pb), total blood calcium (Ca) levels and blood zinc (Zn) levels among children. A cross-sectional study was designed to collect healthy children age 1-36 months (Mean ± SD: 1.4 ± 0.3 age, 55% boys) in the study from January 2012 to September 2013. The overall mean blood Pb, Zn and Ca levels were (41.18 ± 11.13) μg/L, (62.18 ± 13.33) μmol/L and...

Because of the scientific evidence showing that arsenic (As), cadmium (Cd), and nickel (Ni) are human genotoxic carcinogens, the European Union (EU) recently set target values for metal concentration in ambient air (As: 6 ng/m(3), Cd: 5 ng/m(3), Ni: 20 ng/m(3)). The aim of our study was to determine the concentration levels of these trace elements in Porto Metropolitan Area (PMA) in order to as...

Quantification of 26 elements was performed in blood of patients affected by neurodegenerative pathologies, i.e., Alzheimer's disease (AD), Parkinson's disease (PD) and multiple sclerosis (MS), and of a control group to study the potential role of blood elements as markers for the different neurodegenerations. A multivariate discriminant analysis (stepwise method) was applied to determine the b...

Over the past two decades, blood lead levels among U.S. children have been reduced by approximately 80%. This decline reflects both primary interventions (removal of lead solder from food beverage cans and virtual elimination of lead additives from gasoline) and secondary prevention strategies (public health programs and nutritional intervention). Nonetheless, pediatric lead poisoning (i.e., bl...
