Organohalogens, especially organochlorinated compounds (OCs) such as polychlorinated biphenyls (PCBs), have long been recognized as a potential threat to human health and, therefore, these compounds have been widely investigated in foods [3, 27], vegetation [9, 14], and the atmosphere [1, 11]. Recently, interest in using extractable organohalogens (EOX) as parameters for the quantification of t...

Hair is evaluated and compared with urine as a biomonitor for human intake of uranium. Concentrations of U and U and the activity ratio between them are measured in the hair, urine, and drinking water of 24 drilled bedrock well water users in Östergötland, Sweden. The samples are measured with α-spectrometry after radiochemical preparation using liquid-liquid separation with tributylphosphate. ...

ABSTRACT Heavy metals constitute the largest part of air pollution. metals, concentration which in environment is constantly increasing and can remain intact nature for a long time, are great threat to living things. In addition, due fact that it causes bioaccumulation structure things, detection heavy metal very important. However, things areas where traffic exposed exhaust fumes, this signifi...

For the first time, in May 2007, the distributions of polycyclic aromatic hydrocarbons (PAHs) were studied in the soft tissues (STs) (mantle, gills, foot, gonad, muscle, byssus, and remaining soft tissues) of the green-lipped mussel Perna viridis, collected from eight geographic locations along the coastal waters of peninsular Malaysia. The STs of the mussels collected from the eastern part of ...

The drainage of abandoned mines leads to several ecological problems, particularly the acidification of surface freshwater systems and heavy metal contamination. In order to study the possibility of using the behavioural early warning responses of Portuguese indigenous benthic invertebrates to detect an acute short-term pulse of Acid Mine Drainage (AMD), experiments with the Multispecies Freshw...

This 25-y study monitored aquatic and terrestrial gamma-ray-emitting radionuclide levels near a nuclear power plant. It is the only known, long-term environmental survey of its kind. It was conducted neither by a utility owner, nor by a government agency, but rather by a private, environmental research institution. Compared to dozens of other flora and fauna, periphyton was found to be the best...
