Lead can cause liver damage in which free radical reactions are involved. In order to study the effect of lead on liver and gallbladder, we examined human gallbladder bile after cholecystectomy, as well as the liver and bile of broiler chickens fed with basal diet and contaminated with 400 and 600 mg/kg lead (Pb(CH3COO)2. Concentrations of lead in human bile were determined with inductively cou...

A thio carboxylic acid derivative: 2-aminocyclopent-1-ene-1-carbodithioic acid (ligand) was synthesized and characterized. It was used as a colorimetric chemo sensor (chads) for Ni. The absorption maximum of ligand and Ni shows a shift from 390 nm to 420 nm in absence of buffer solutions. The change in color is very easily observed by the naked eye, while other metal cations, such as Fe, Co, Hg...

To better understand how renal Na(+) reabsorption is altered by heavy metal poisoning, we examined the effects of several divalent heavy metal ions (Zn(2+), Ni(2+), Cu(2+), Pb(2+), Cd(2+), and Hg(2+)) on the activity of single epithelial Na(+) channels (ENaC) in a renal epithelial cell line (A6). None of the cations changed the single-channel conductance. However, ENaC activity [measured as the...

Glacial episodes have been linked to Ordovician-Silurian extinction events, but cooling itself may not be solely responsible for these extinctions. Teratological (malformed) assemblages of fossil plankton that correlate precisely with the extinction events can help identify alternate drivers of extinction. Here we show that metal poisoning may have caused these aberrant morphologies during a la...

Using two biological characteristics of the land snail (subspecies Helix aspersa aspersa and Helix aspersa maxima), i.e., soil eating and crawling on wet surfaces, methods were developed to assess the bioavailability of heavy metals (Cd, Cr, Pb, and Zn) from soil and aqueous leachates of soil. Measurement of heavy-metal concentrations in soil, leachates, and soft tissues of snails showed that c...

Water spinach is a vegetable that rich in benefits, apart from the benefits it has, can also be mediator for spread of heavy metals to humans. One contaminants contaminate lead (Pb). Lead (Pb) pollutant occurs big cities and has toxic properties. contamination water occur due influence motor vehicle exhaust, waste, fertilizers pesticides containing metals. vegetables such as have adverse effect...

1. The effect of a pretreatment with phenobarbitone (PB) on the porphyrinogenic action exerted by hexachlorobenzene (HCB) was examined in female rats. 2. Kinetic studies of enzyme function after HCB poisoning showed that porphyrinogen carboxy-lyase was the only enzyme of haem biosynthesis that markedly lowered its activity. Both stages of uroporphyrinogen (UPG) III decarboxylation were decrease...

We read with great interest the article entitled “An arrhythmic episode after mercury exposure and successful treatment with chelation therapy: A case report.” by Karakulak et al. (1) reporting a case of acute mercury (vapor) poisoning followed by 7-day history of malaise, fatigue, proximal weakness in the legs and in the arms, atypical chest pain, and palpitation in a 32-year-old woman in publ...

BACKGROUND Lead (Pb) is a toxic substance with well-known, multiple, long-term, adverse health outcomes. Shooting guns at firing ranges is an occupational necessity for security personnel, police officers, members of the military, and increasingly a recreational activity by the public. In the United States alone, an estimated 16,000-18,000 firing ranges exist. Discharge of Pb dust and gases is ...

The sugar factory located in Palleko Village can produce air pollution and waste which is suspected to pollute the environment waters. Environmental form of lead metal contaminate water soil around industrial plants. thought be higher than on land because it polluted from mining processes waste. Lead able plants water, for example kale, a mediator spread heavy metals living things due entry the...
