ORGANOHALOGEN COMPOUNDS – Volume 66 (2004) 278 Introduction Most of the PCB pollutions are caused by industrial application. PCB-containing mixtures whose compositions are well known and constant should be rapidly and precisely analyzable as total PCB to monitor real pollution exposure. Consequently, a simple but reproducible and cheap method for operative control is needed which should be peri...

Aquatic environments are among the most vulnerable habitats that affect all Organisms. The Persian Gulf is home to numerous plant and animal species, biological safety at risk due its human activities. Traffic of oil commercial vessels in area, waste water, desalination, proximity industrial, refinery petrochemical units shores rivers, rigs, fishing, tourism activities potential hazards environ...

background: copper is a trace element vital to life, but the toxic effect of water pollution with it on fish is now exhibited. fish blood is susceptible to contamination-induced stress and its alternation due to the hematological and immunological parameters can be utilized as toxicity indices of xenobiotics. methods: in this study, juvenile species of silver carp with average weight of 200gr w...

We explore the possibility of extracting the weak phase γ from pure tree decays Λb → Λ(D0,D0,D0 CP ) in a model independent way. The CP violating weak phase γ can be determined cleanly, without any hadronic uncertainties, as these decay modes are free from the penguin pollutions. Furthermore, neither tagging nor time dependent studies are required to extract the angle γ with these modes. Typese...

The paper presents a cost-effective device designed for measuring and monitoring the TDS (total dissolved solids) level of drinkable, surface (lakes, rivers) and/or industrial waters. Providing a first reading of potential water pollutions, the device is dedicated to the sectors of environment and consumer protection. The device was implemented and a series of continuous measurements is depicte...
