The post larvae (PL) of Macrobrachium rosenbergii (2.5 cm and 0.15g) were subjected to static renewal type acute toxicity tests against cadmium chloride (CdCl2), chromium trioxide (CrO3) and lead nitrate (Pb(NO3)2). The 96 h LC50 values were calculated to be 58.93 μg/L, 2.08 mg/L and 25.97 mg/L for CdCl2, CrO3 and Pb(NO3)2 respectively. PL were exposed to the 96 h LC50 concentrations of these h...

Two new lead(II) complexes [Pb(pcih)(bha)] (1) and [Pb(pcih)(NO3)] (2, Hpcih = 1,4-bis(3-pyridyl)-2,3-diazo-1,3-butadiene, Hbha = 2-hydroxybenzoic acid) have been synthesized by solvothermal methods and structurally characterized. The single-crystal X-ray data show that the coordination spheres of the Pb2+ ions in 1 and 2 are hemidirected with stereochemically active electron lone pairs. There ...

Heavy metals (Cd, Pb, Cu, Zn) absorbed by roots brought about oxidative stress conditions through ROS production (O2̄ ̇, H2O2) for pea plants cultivated hydroponically for 96 h on a Hoagland medium with the addition of 50 μM: CdCl2, Pb(NO3)2, CuSO4, and ZnSO4. We shows, using laser ablation ICP MS, that Cd, Cu, Pb, and Zn elements are located along a cross-section through the roots of pea plants...

Background: Reprocessing of sewage sludge to agricultural land is preferred to disposal through landfill or incineration due to its potentially beneficial effects on soil fertility from organic matter and plant nutrients, such as N and P, present in the sludge. Therefore, this study was conducted to investigate the impact of sewage sludge and chemical fertilizers on Pb and Cd accumulation in ...

heavy metal hyperaccumulators have recently attracted considerable attention in remediation of an area's pollutants. lead (pb) is one of the main pollutant heavy metals that its relatively high concentration have been reported in some environments. in present study, the potential of turfgrass tolerance, regarding seed germination and plant establishment were evaluated, in different concent...

Background: The present study compared lethal concentrations (LC50-96 h) of CdCl2, CrCl3, and Pb (NO3)2 between two scaled and scaleless freshwater fish species: Cyprinus carpio (Cyprinidae) and Pangasius hypophthalmus (Pangasiidae). Methods: The experimental fishes were obtained from fish markets/ponds with average lengths and weights of approximately 11.68 ±1.92 and 9.8±1.9 cm, and 25.92±6....

Red crayfish, Procambarus clarkii, is widely farmed in the southern states of Louisiana and Texas. It is the most valuable of commercial crayfish species in the United States, where it is considered a delicacy. In recent years, its availability has decreased due to environmental contamination by toxic chemicals including lead. In the present study, we conducted a ninety-six-hour static renewal ...

The present study was an attempt to investigate toxic effects of lead on red blood corpuscle (RBC) under in vitro conditions. Venous blood samples from adult, healthy, well-nourished male donors falling in age group of 25-30 years were collected in EDTA vials for preparation of RBC suspension. These donors were the residents of an area of Bhuj, where soil was not contaminated with lead and also...
