The effect of paper mill effluent on the physico-chemical properties of soils was studied under natural environment in pots experiment. The soil was treated to six rates of effluent viz. 5, 10 25, 50, 75 and 100 ml/Kg soil. The physico-chemical properties of the soil were determined before and at the end of the experiment, 12 weeks after irrigation with the effluent. Results revealed that among...

The effect of seven rates viz. 0 (control), 5, 10 25, 50, 75 and 100 ml/Kg of treated distillery effluent on the physico-chemical properties of soils was studied under natural environment in pot experiment. The characteristics of the soil were determined before and after 12 weeks of effluent irrigation. The results revealed that the 100% concentration of distillery effluent decreased BD (5.63%)...

Under varying conditions the reaction of cysteamine hydrochloride (SHCH2CH2NH3)Cl with stoichiometric amounts of Cd and Pb salts in water gave [Cd2.5Cl5(SCH2CH2NH3)] (1), [Cd(SCH2CH2NH2)2] (2), [Pb2Cl(SCH2CH2NH2)3] (3) and [Pb2(SCH2CH2NH2)3](NO3)0.67(Cl)0.33 (4). Compound 1 is a molecular solid, one that contains a solid state-like core, but is nevertheless soluble in common organic solvents. T...

In this work, trioctylphosphine oxide (TOPO) ligand is employed to improve the quality of CsPbBr1.2I1.8 quantum dots (QDs) films. Lead nitrate (Pb(NO3)2) also used passivate surface The study and passivation on luminous efficiency red light-emitting diode (LED) discussed. QDs films co-doped with TOPO Pb(NO3)2 can effectively performance LEDs due reduction non-radiation recombination carriers sm...

over the years, there has been an obvious pollution problem in lagos area, nigeria with high population of over eleven million and the near absence of waste management infrastructures. concentrations of some pollution parameters and trace elements (temperature, ph, salinity, so42-, no3-, po43-, f-, do, bod, cod and coliform, cr, co, ni, ag, cd and pb) were determined from water bodies of isolo ...

A espectrometria de absorção atômica em forno de grafite de alta resolução com fonte contínua (HR-CS GF AAS) é proposta para determinar Pb em sombra de olho e blush empregando a análise direta de sólidos. O emprego da mistura de modificadores químicos Pd(NO3)2 + Mg(NO3)2 possibilitou a calibração aquosa de 0,25 a 2,5 ng Pb (r = 0,998). O desempenho do método proposto foi avaliado por meio da an...

The present study was conducted to assess quantitative information about lead (Pb) contamination in soil on the growth and physiology of wheat. Solutions with three different concentrations of Pb as [Pb(NO3)2 at 500, 1000 and 2500 microM] were incorporated into the soil to achieve Pb-stressed conditions in comparison to unstressed, water treated, control variant. Wheat growth measured in terms ...

Pb+ intoxication causes anemia that is partially due to a decreased life span of circulating erythrocytes. As shown recently, a Ca(2+)-sensitive erythrocyte scramblase is activated by osmotic shock, oxidative stress, and/or energy depletion, leading to exposure of phosphatidylserine at the erythrocyte surface. Because macrophages are equipped with phosphatidylserine receptors, they bind, engulf...

Soil microbial activity is adversely affected by pollutants such as heavy metals, antibiotics and pesticides. Organic amendments including sewage sludge, municipal compost and vermicompost are recently used to improve soil structure and fertility. But, these materials contain heavy metals including Pb, Cd, Zn, Ni and Cu that are toxic to soil microorganisms and may lead to occurrence of more to...
