Heavy metals are metallic elements which have a high atomic weight and a density much greater (at least 5 times) than water. There are more than 20 heavy metals, but four are of particular concern to human health: lead (Pb), cadmium (Cd), mercury (Hg), and inorganic arsenic (As). According to the U.S. Agency for Toxic Substances and Disease Registry. These four heavy metals are four of the top ...

How Mining Releases Toxic Metals Large amounts of waste rock and tailings contaminated with toxic metals can be produced by mine sites. In the case of the Donlin Creek mine, there are only 0.072 ounces of gold for every ton of ore, a figure that does not take into account the waste rock. Toxic substances contained within the rock and tailings are more easily released once these substances are p...

Dyes are one of prevalent types of chemicals used by human being today. Dyes are organic compounds which have complex aromatic molecular structure that make them toxic and harmful. When these dyes introduced with water due to textile dyeing and printing industrial waste water may cause problems to all living organism. In these dyes highly toxic metals are used as mordents so the removal of thes...

It contains toxic chemicals and hazardous materials from several diagnostic and treatment processes. The improper disposal of Medical waste in the CMCH poses a high health risk to humans as well as the environment. This study was carried out from July ...

Aminopolycarboxylate chelants (APCs) are extremely useful for a variety of industrial applications, including the treatment of toxic metal-contaminated solid waste materials. Because non-toxic matrix elements compete with toxic metals for the binding sites of APCs, an excess of chelant is commonly added to ensure the adequate sequestration of toxic metal contaminants during waste treatment oper...

Electroplating and metalworking industries discharge large amounts of heavy metals, including copper (Cu), nickel (Ni) and zinc (Zn) ions, in their effluents have been recognized as a major problem to human health and aquatic life. Copper is highly toxic because it is non biodegradable and carcinogenic, Copper has been reported to cause neurotoxicity commonly known as “Wilson’s disease” due to ...

introduction medical waste contains highly toxic metals, toxic chemicals, pathogenic viruses and bacteria, which can lead to pathological dysfunction of the human body. the hazards of exposure to hospital waste can range from gastro-enteric, respiratory, and skin infections to more deadly diseases such as hepatitis b & c, and hiv/aids. additionally, medical waste contains potentially harmful mi...

The proper disposal of electrical and electronic waste is currently a concern of researchers and environmental managers not only because of the large volume of such waste generated, but also because of the heavy metals and toxic substances it contains. This study analyzed printed circuit boards (PCBs) from discarded computers to determine their metal content and characterized them as solid wast...
