PCB bioaccumulation in three mullet species—A comparison study

Mathematical modeling of PCB bioaccumulation in Perna viridis.

In the present work, we built a mathematical model of polychlorinated biphenyl (PCB) bioaccumulation in Perna viridis, namely, a one-compartment model with a time dependent incorporation rate R (microg g(-1) lipid per ppb water per day), with positive substrate cooperativity as the underlying physical mechanism. The temporal change of the PCB concentration Q (microg g(-1) lipid) in the soft tis...

Bioaccumulation, alterations of metallothionein, and antioxidant enzymes in the mullet Mugil cephalus exposed to hexavalent chromium

A laboratory experiment was conducted to determine hexavalent chromium (Cr) accumulation in the mullet and investigate Cr toxicity using a panel of biomarkers including metallothioneins (MTs), glutathione (GSH), glutathione S-transferase (GST), and superoxide dismutases (SODs) for 4 weeks. Cr bioaccumulation in all tissues, except muscle, was consistently timeand dose-dependent. The accumulatio...

Effects of Carbon Amendments on Ecological Responses and Pcb Bioaccumulation in Lumbriculus Variegatus

Several studies have shown that sediment associated black carbonaceous particles can reduce aqueous and bioaccumulated concentrations of hydrophobic organic compounds (HOCs) in benthic organisms. Therefore, carbon amendments (e.g. activated carbon, AC) have been studied as stabilization method for contaminated sediments. However, it appears that the amendments may have also direct adverse effec...

a comparative study of the theme of "marriage" in three victorian novelists: charles dickens, george eliot and thomas hardy

این تحقیق کوشیده است با انتخاب پنج رمان از میان آثار برگزیده، «چارلز دیکنز»، «جورج الیوت» و «توماس هاردی » و با رویکردی تطبیقی به بررسی درونمایه ی «ازدواج» در آثار این سه رمان نویس بزرگ دوره ی ویکتوریا بپردازد. فرضیه ی اولیه ی تحقیق این بوده است که چارلز دیکنز (1870- 1812) با زبانی شوخ و گزنده، جورج الیوت(1880- 1819) با نگاهی آموزشی–اندرزگونه و توماس هاردی(1928- 1840) با رویکردی تلخ وانتقادی به...
