Water and sediment samples were collected from six different stations, located along the Nil River between February and June 2015. Concentrations of cadmium, lead, zinc, and copper were determined. The extent of the sediment pollution was assessed, using the multiple pollution indices, namely contamination factor (CF), pollution load index (PLI), and the geoaccumulation index (Igeo). The result...

concentrations of elements (as, co, cu, ni, mo, pb, v, cd, cr and zn) are studied in the surface sediments of bakhtegan lake, northwest of nyriz city, iran, to assess metal contamination. the average abundance order of trace elements content in bakhtegan lake sediments is cr>ni> v> zn> cu> co> as> pb> mo>cd. the comparison of trace elements concentration in bakhtegan lake sediments with toxicol...

This study aimed to evaluate concentrations of selected heavy metals in the soils of Ilokun dumpsite and adjourning farmlands, and to determine as well levels of heavy metals uptake in various parts of Carica papaya plant collected from the dumpsite. Twenty-two soil samples were collected within the dumpsites and farmlands at depths of 0-20 cm and 20-40 cm. Evaluations of heavy metals ...

BACKGROUND One complication of total knee arthroplasty (TKA) is patella baja (PB). Patellar tendon shortening and joint line elevation are two main causes of PB. The purpose of this study was to determine the incidence of PB before and after TKA by measuring the patellar height and provide evidence for choosing a suitable index. METHODS In total, 256 consecutive patients who underwent primary...

Background: The presence of toxic heavy metals in cereal grains like rice is one of the main human and environmental health concerns. Their importance is because of their non-biodegradability nature, high half-time, and bioaccumulation ability in the human body. Among heavy metals, cadmium (Cd), lead (Pb), and arsenic (As) are most critical, so their concentrations in rice were evaluated in thi...

The aims of this study were to determine Cd and Pb contents in wild mushrooms from the eastern region of the “Green Lungs” of Poland (GLP), compare them to Cd and Pb contents in some popular species of cultivated mushrooms, and evaluate mushroom contribution to the daily intake of Cd and Pb. Trace elements were determined in 21 species of edible mushrooms: 18 species of wild mushrooms and 3 spe...

Paired vegetable/soil samples from New York City and Buffalo, NY, gardens were analyzed for lead (Pb), cadmium (Cd) and barium (Ba). Vegetable aluminum (Al) was measured to assess soil adherence. Soil and vegetable metal concentrations did not correlate; vegetable concentrations varied by crop type. Pb was below health-based guidance values (EU standards) in virtually all fruits. 47% of root cr...

background: cigarette butts have been shown to release numerous kinds of chemicals such as heavy metals in water and may be a continual source of aquatic environments contamination after discarding. the objective of the present study was to determine the concentration of cd and pb in cigarette filters of different iranian and non-iranian brands in smoked and non-smoked samples. methods: ten dif...

Bank voles free living in a contaminated environment are known to be more sensitive to cadmium (Cd) toxicity than the rodents exposed to Cd under laboratory conditions, but the reasons for this difference are poorly defined. The present work was designed to determine whether dietary lead (Pb), a common environmental co-contaminant, and/or animal density that affects various physiological proces...

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...
