The properties of Ehrlich ascites tumour cells exposed in vivo to cadmium were investigated as a function of the zinc status of the host animals. Tumour-cell growth was inhibited by cadmium in both zinc-sufficient and zinc-deficient animals. However, cells in zinc-sufficient tumours accumulate much less cadmium than those in deficient tumours. The subcellular distributions of cadmium and zinc d...

BACKGROUND We present herein our results regarding the accumulation of four heavy metals (copper, cadmium, lead, and zinc) in four aquatic species plants (Ceratophyllum demersum, Potamogeton pectinatus, Potamogeton lucens, Potamogeton perfoliatus) collected from the Danube River, South-Western part of Romania and their possible use as indicators of aquatic ecosystems pollution with heavy metals...

A hydroponic experiment was carried out to investigate the effect of cadmium treatments at (0.3, 0.6, 0.9 and 1.2 mg/l), zinc at (2, 4, 6 and 20 mg/l) and combined cadmium-zinc at (0.6 mg/l Cd plus 2, 4, 6 and 20 mg/l Zn) on rooting, nutrient uptake in cowpea seedling. The results showed that increasing Cd supply markedly reduced the rooting of seedling. Increased Cd accumulation in cowpea seed...

cadmium is one of the most toxic pollutants in the surface soil layer the accumulation of which in soils as well as in crops is of increasing concern. in addition, zinc is a micronutrient in rice nutrition which is in interaction with cd. a pot experiment was carried out to study the effects of zinc and cadmium on rice growth and as well on concentrations of zn, cd, fe and mn in soil. a factori...

Soil samples were randomly collected from 422 vegetable gardens in a study area centered in downtown Baltimore, Maryland, and having a radius of 48.28 km (30 miles). The levels of lead, four other metals (cadmium, copper, nickel, and zinc), and pH were measured for each location. The application of multi-response permutation procedures, which are compatible with mapping techniques, reveals that...

The heavy metal concentration of sewage sludge increased during composting for cadmium, chromium, lead and zinc and decreased for copper and nickel. Cadmium and lead were the most variable of the metals, copper and zinc the least. Variability within a batch was small (variation of 4-12%). Variability attributable to batch-to-batch differences was generally larger (variation of 4-37%). The varia...

Background: Cadmium is an extremely toxic metal with ubiquitous environmental distribution. Cadmium is a potent reproductive and developmental toxic agent, and intensive environmental exposure to this substance has been reported among the residents of Tehran. In this study, we investigated the correlation between amniotic fluid cadmium levels and the risk of preeclampsia, prematurity and low bi...

Cadmium and zinc concentrations in kidney and liver have been measured under different exposure situations in different species including man. The results show that zinc increases almost equimolarly with cadmium in kidney after long-term low-level exposure to cadmium, e.g., in man, horse, pig, and lamb. In contrast, the increase of zinc follows that of cadmium to only a limited extent, e.g., i...

abstract nowadays, soil pollution with heavy metals has become a major problem which their accumulation in plants can directly or indirectly influence on animals and humans life. lead and cadmium are poisonous metals, with increasing the amount of these metals in environmental pollution; they will be increased in food chain significantly. in this research, three levels of cadmium (0, 100 and 20...
