As a result of high poverty level in Africa, however, the consumption of ICTs is concentrated on the inferior and used components, which soon become unserviceable and abandoned. Along with the hazardous chemical substances contained in them in significant quantity they are often discarded improperly....

Fifty most hazardous substances in the United States based on: (1) substance must be identified at 3 or more Superfund National Priority Listing (NPL) hazardous waste sites or facilities [62]; (2) substance's toxicity; and (3) concentration of the substance in environmental media at sites, ...

The efficiency of geopolymers as an effective immobilization system for various hazardous waste materials can be enhanced by adding PbO to improve its radiation shielding characteristics. In this study, the impact of PbO addition on the shielding properties of geopolymer composites was examined to evalu...
Department of Energy low-level mixed waste streams that include hazardous metals and low-level radioactive elements. Using this ceramic, the authors solidified, in monolithic waste forms, low-level mixed waste streams containing various levels of PbCl2 and PbCO3....
"When you are relying on the blood lead level in children to indicate whether there is lead in the environment, we are basically using the children as canaries in the mine," said Dr. Philip Landrigan, a Boston College biology professor who directs the school's Program for Global Public Hea...
In fact, the water in one home was tested by Virginia Tech researchers as having lead levels at 13,200 ppb — over three times the level considered to be hazardous waste. Unfortunately, a child living in that home was diagnosed with lead poisoning. Additional resources Los Alamos National ...
10 micrograms per square foot is considered hazardous on floors, and a concentration 10 times that high is considered hazardous on window sills. The new rule brings both of those levels down to no detectable lead.The proposed rule also would reduce what level is allowed when a lead-abatement ...
These effects are unique to material, and it is my understanding (needs to be proven) that at NP level many of such characteristics such as Minimum ignition, concentration, oxidant requirement, dispersion could be generalized (given combustibility of the dust). These are worth investigation. This...
