Quantitation of lead-210 ( 210 Pb) using lead-203 ( 203 Pb) as a “Massless” yield tracer

Use of lead-210 as a novel tracer for lead (Pb) sources in plants

Lead (Pb) released from anthropogenic sources and stored in environmental repositories can be a potential source for secondary pollution. Here we develop a novel approach for tracking Pb from atmospheric deposition and other sources in the environment using fallout (210)Pb as a tracer, and apply the method to samples collected from Richmond Park, London, the UK. The mean ratio of (210)Pb to tot...

Wst 47(11) 203-210

In lab-scale experiments at the 2-stage activated sludge pilot plant of Vienna’s central WWTP it is shown that the wastewater soluble COD concentration, which is inert to a sludge with SRT < 1 d (SIA) is about double compared to the SI concentration in sludge with SRT > 10 d (SIB). Unexpectedly the ratio of SIA/SIB is independent of the sludge age between SRTs of 0.4 and 1.0 days. The differenc...

Biliary excretion of 203 Hg, 64 Cu, 52 Mn, and 210 Pb in the rat.

Bioaccumulation of 210 Po and 210 Pb in Arctic seabirds

INTRODUCTION When considering the potential radiological impacts of anthropogenic radionuclides in the environment, it is important to understand the doses incurred by biota by natural activity concentrations of naturally occurring radionuclides. Naturally occurring Po (half-life138 days) and Pb (half-life 22.3 years) are members of the U decay chain. In the marine environment, Po and Pb are pr...

Lead (Pb) Toxicity; Physio-Biochemical Mechanisms, Grain Yield, Quality, and Pb Distribution Proportions in Scented Rice

Lead (Pb) caused interruptions with normal plant metabolism, crop yield losses and quality issues are of great concern. This study assessed the physio-biochemical responses, yield and grain quality traits and Pb distribution proportions in three different fragrant rice cultivars i.e., Meixiangzhan-2, Xinagyaxiangzhan and Basmati-385. Plants were exposed to 400, 800, and 1,200 ppm of Pb while po...
