additions utilizing a graphite furnace; lead was determined by anodic stripping voltammeter with standard additions. All other metals were determined simultaneously with one pass through a DC plasma spectrograph. Additional details on these methods are available in Holmgren et al. (1993). Results

Toxic optic neuropathy is a diagnosis of exclusion, with patients typically presenting with [1] [2] : A history of drug, medications, or alcohol use. Painless, bilateral, and symmetric vision loss. Progressive loss of visual acuity that usually starts with a blur at the point of fixation. Dyschromatopsia.

The directive recommends that soil lead levels less than 400 mg/kg are generally safe for residential use. Above that level, the document suggests collecting data and modeling blood-lead levels with the IEUBK model. For the purposes of screening, therefore, 400 mg/kg is recommended for residential soils.

Heavy metal is a broad term used to describe a group of naturally occurring metallic elements of high molecular weight and density when compared to water.[1] At low concentrations, certain heavy metals, such as iron, zinc, copper, and manganese, are essential for human survival but can become toxic agents at higher concentrations. Other …

Toxic metals, including "heavy metals," are individual metals and metal compounds that negatively affect people's health. Some toxic, semi-metallic elements, including arsenic and selenium, are discussed in this page. In very small amounts, many of these metals are necessary to support life. However, in larger amounts, they become toxic.

The TCLP, or Toxicity Characteristic Leaching (not Leachate) Procedure is designed to determine the mobility of both organic and inorganic analytes present in liquid, solid, and multiphasic wastes. This is usually used to determine if a waste may meet the definition of EP Toxicity, that is, carrying a hazardous waste code under RCRA (40 CFR ...

In order to investigate the toxicity-resistance of eighteen Chinese native plants in lead (Pb)-zinc (Zn) mine tailings, we categorized their resistance to Pb and Zn, and tested their potential for phytoremediation effectiveness of Pb and Zn. Fourteen woody plant species belonging to 12 families, and 4 herbaceous species belonging to 4 families, were …

Children at risk because of lead in their environment are often not found until elevated blood lead levels (BLLs) are detected during routine screening. At that point, …

For example, at or near a pH of 7.0 lead binds tightly to soil particles, and its solubility is very low. Similar relationships exist for arsenic, chromium, and copper. The chemicals barium, cadmium, lead, and zinc have less plant uptake at high pH (>6.5). Periodic of soils can help reduce exposure risk. Add Organic Matter.
