We report on a new Pb(II) coordination polymer [Pb(HL)(NO3)2]n (1), obtained from direct reaction of Pb(NO3)2 with N'-4-(dimethylamino)benzylideneisonicotinohydrazide (HL). The sphere around the cation is built by 1,4-N,O-chelating neutral HL, six oxygen atoms three chelating nitrate anions, and pyridyl nitrogen donor symmetry related molecule. ligand HL one acting as bridging species, yield tw...

One of the most well-known naturally occurring environmental heavy metals, lead (Pb) has been reported to cause liver injury and cellular apoptosis by disturbing the prooxidant-antioxidant balance via oxidative stress. Several studies, on the other hand, reported that mangiferin, a naturally occurring xanthone, has been used for a broad range of therapeutic purposes. In the present study, we, t...

Water is essential part of ecosystem, so its quality must be ascertained for use especially in Ekole creek Nigeria where dredging activities heavy, hence this study examined the effect on downstream water creek. samples were collected from four points which are; Upstream, Dredge I, II, and Downstream points. The parameters determined showed that Turbidity Total Suspended Solids (TSS) higher at ...

The purpose of this study is to analyze the chemical composition of wet precipitation in samples collected at three stations in the Candiota region in the Brazilian state of Rio Grande do Sul (RS). Samples were collected in 2004. Variables analyzed in wet precipitation were pH, conductivity, and concentration of Cl-, NO3-, SO4(2-) F-, Na+, Ca2+, Mg2+, K+, NH4+, Cu, Zn, Fe, Mn, Pb, Ni, Cd, Co, a...

Invertase was purified from rose (Fructus cynosbati) hips by ammonium sulfate fractionation and hydroxyapatite column chromatography. The enzyme was obtained with a yield of 4.25% and about 10.48-fold purification and had a specific activity of 8.59 U/mg protein. The molecular mass of invertase was estimated to be 66.51 kDa by PAGE and 34 kDa by SDS-PAGE, indicating that the native enzyme was a...

This study aimed to evaluate the effect of maternal aerobic training and curcumin (Cur) supplementation on protecting motor function (e.g., muscle strength relaxant activity) from harmful effects lead nitrate (Pb[NO3]2) exposure in female male offspring BALB/c mice. The experimental groups included a healthy group, intraperitoneally Micro-Cur-treated group (50 mg/kg body weight), (received once...

Translocation of micronutrients was investigated in Phaseolus vulgaris (var. Annapurna) grown on soil amended with paper mill sludge. The plants of P. vulgaris were grown in soil amended with 20%, 40%, 60%, 80%, and 100% paper mill sludge to study the accumulation and translocation of iron (Fe), zinc (Zn), cadmium (Cd), copper (Cu), chromium (Cr) and lead (Pb) in plant parts (shoot, root, leave...

Permanent modifiers (Zr, W, Ru, Zr–Ru and Zr–W) thermally deposited on platforms inserted in pyrolytic graphite tubes and Pd 1 Mg(NO3)2 conventional modifier mixture have been employed for the determination of cadmium and lead in dissolved environmental, botanic and biological samples by electrothermal atomic absorption spectrometry (ETAAS). Optimum masses and mass ratios of permanent modifiers...

A range of soil amendments including diammonium phosphate fertilizer (DAP), municipal biosolids (BS), biosolids compost, and Al- and Fe-based water treatment residuals were tested on Pb-, Zn-, and Cd-contaminated yard soils and tailings at the Tar Creek NPL site in Oklahoma to determine if amendments could restore a vegetative cover and reduce metal availability in situ. For the yard soils, all...
