The illegal dumping of hazardous waste poses a danger to the environment when pollutants migrate into water sources and ultimately cause widespread infection or toxicity, endangering the health of humans who might become exposed to infection...

The classical method of melting lead by fire-assay (Pb-FA) is the most frequently used analytical technique in gold prospection. The crucible solid waste which is generated in this process is usually characterized by chemical and mineralogical composition, granulometric size distribution, and classified according to Brazilian Environmental Regulations. This study demonstrates how acid leaching ...

With the Basel ban, imposing restrictions on Trans-boundary movement of hazardous wastes, coming into force with effect from 1.1.1998, the concept of treatment and safe disposal of hazardous wastes (HWs) assumes paramount significance. The annual HW generation in India is estimated at 0.3-0.5 million tonnes. As per the ideal industrial siting criteria in India, the industry should have enough l...

Co-processing of hazardous wastes in cement kilns have for decades been thought to cause increased emissions of PCDD/PCDFs--a perception that has been evaluated in this study. Hundreds of PCDD/PCDF measurements conducted by the cement industry and others in the last few years, on emissions and solid materials, as well as recent test burns with hazardous wastes in developing countries do not sup...

Toxicology research in the nanotechnology area has focused primarily on human inhalation, ingestion or dermal exposure. Less research has been published on the impact to ecological systems resulting from a release of nanomaterials. Environmental laws such as CERCLA ("Superfund") address the release of "hazardous substances" by obligating the party releasing the substance to (a) report the relea...
