The Kirki project aimed to identify, among the mining waste abandoned at a mine and processing plant, the most critical potential pollution sources, the exposed milieus and the main pathways for contamination of a littoral area. This was accompanied by the definition of a monitoring network and remedial options. For this purpose, field analytical methods were extensively used to allow a more pr...

The low-level salt waste (LAW) associated with the production of nuclear materials at US Department of Energy (DOE) facilities will be disposed of in shallow land burial sites managed by the DOE. Two of the primary contaminants of interest are Tc-99 and I-129, both soluble and long-lived radionuclides. Cs-137, a short-lived, strong gamma emitter is also a soluble contaminant of concern. In addi...

Significant quantities of toxic metals are emitted to the air by the incineration of waste, as well as by the combustion of coal and oil. To optimize the regulations for their emissions one needs to know the cost of their damage. That requires an impact pathway analysis, with realistic dispersion models, exposure-response functions, and monetary values. In this article we explain the method and...

Risk analysis of urban aquatic systems due to heavy metals turns significant due to their peculiar properties viz. persistence, non-degradability, toxicity, and accumulation. Akkulam Veli (AV), an urban tropical lake in south India is subjected to various environmental stresses due to multiple waste discharge, sand mining, developmental activities, tourism related activities etc. Hence, a compr...

background: dental waste can be hazardous to humans and the environment. objective: to determine the current status of dental waste management in private and public dental clinics and private dental offices in shiraz, southern iran. methods: this cross-sectional study was conducted at the shiraz university of medical sciences from february through june 2013. a stratified random sampling method ...

In recent history the volume of electronic products purchased by consumers has dramatically escalated. As a result this has produced an ever-increasing electronic waste (E-waste) stream, which has generated concerns regarding the E-waste's potential for adversely impacting the environment. The leaching of toxic substances from obsolete personal computers (PCs) and cathode ray tubes (CRTs) of te...

Transition metal ion has been receiving a great attention in the recent years, as the high concentration of toxic metal ions. This paper deals with short review and to study the various types of transition metals present in waste water released from Pulp and Paper effluents. These are being constantly poured into the environment, which result in the long lasting bio-hazards in the aquatic eco-s...

The ever increasing pile-up of electronic waste in dumping sites, especially in developing countries such as China, Pakistan, India and several African countries, might have caused a significant alteration in the microbial community of the contaminated sites. This change in the microbial population may have significant impact to the soil ecology function. The major pollutants of electronic wast...

Present work is a part of developing novel recycling technique for waste printed circuit boards (PCBs) i.e. the liberation of metals from PCBs by organic swelling followed by the treatment of resin to remove/ recover hazardous soldering materials. In order to recover the hazardous metallic constituent lead from the liberated resin, initially the leaching studies were made using fresh solder con...
