The “Social cost of carbon” and climate change policy
Economist Frank Ackerman has called the “social cost of carbon” the most important number you never heard of. What is the social cost of carbon, where do the numbers come from, and why should policymakers take care when using them? The Obama Administration (and the Bush Administration before it) uses the SCC to assess the benefits of regulations that would limit emissions of carbon ...

Huge Price Increases Underway from Lamp Manufacturers: The impact of rare earth metals shortages
Brace Yourself for Record Price Increases from the Lamp Manufacturers. As we first reported in June, there is a rapid, emerging shortage of rare earth metals, a primary component used in the manufacture of fluorescent lamps - principally phosphors. Phosphors are transition metal compounds or rare earth compounds of various types. The most common uses of phosphors are prevalent in green ...

Sea Power 101: Notable Case Studies
Russian Air Force Base, Eastern Germany: Land underneath this site had become contaminated over a long period of time by a mixture of lubricant oils, hydraulic fluids and aviation fuel. Following excavation, the soil was reconstituted in biopiles and applied with Sea Power 101. The vast majority of hydrocarbons were removed in the first month, and the site was fully remediated within four months. ...

Africa Analysis: Regional climate plan deserves support
A new southern African climate plan is impressive, but needs more funding if it is to plug the continent's data gap, writes Linda Nordling. Africa's rain-fed agriculture and high poverty levels mean it can’t roll with the punches of an unpredictable climate. But detailed studies on how climate change might affect areas of Africa are often thwarted by a lack of climate data. Now the ...

Biodegradability of substances discharged to the aquatic environment
The term "biodegradability" is much used today, when most people, due to media exposure, are aware of the "environment" and "pollution". To say that a product or substance is "biodegradable" infers to the layman that it is ecologically "safe". Certainly it is safer than substances that contain persistent toxins (e.g. some pesticides, chlorinated hydrocarbons, tributyl tin, heavy metals etc). ...

An assessment of the toxicity of pyridinium chlorides and their biodegradation intermediates
Toxicity investigations were conducted for four pyridinium chlorides belonging to cationic surface-active substances (CSAS), which differed from each other in the numbers of methyl groups (CH(3)) in pyridinium ring. The crustacean Daphnia magna, the fish Lebistes reticulatus and the alga Scenedesmus quadricauda were chosen as biotests. Toxicity of examined preparations appeared to be very high ...

Test organisms behaviour on municipal and industrial wastewater quality assessment
Industrial wastewaters quality became a target for the environmental toxicity assessment nowadays. When there are issues with complex effluents for which many chemicals cannot be quantified and/or interactive effects are likely to be significant, the use of bioassays with different test species becomes a more reliable way in the assessment of toxicity. Ecotoxicity evaluation of the several ...

Radioactive Clean-up
Radioactive, nuclear, or radiation clean-up is considered the most dangerous, difficult, and costly remediation activity after a nuclear disaster or accident. The contamination may be found in the air, water, and soil, as wells as equipment and buildings (USEPA, 2010).Radioactive material, unlike most matter, is inherently unstable. Over time, the nuclei of radioactive atoms emit what's known as ...

An alternative to biological treatment for sewage
Most sea-side towns discharge sewage into the sea, normally some distance off-shore, via an extended out-fall sewer. A town of 100,000 population will produce more than 14,000 cubic metres (3,000,000 gallons) of sewage every day of the year. No small problem. In some coastal locations the sewage used to receive only basic, simple treatment, usually "screening" to remove any large objects, ...

California’s Prop 65 and Cadmium Public Health Dangers
In 1986, California voters approved an initiative to address increasing concerns about exposure to toxic chemicals. That initiative, the Safe Drinking Water and Toxic Enforcement Act of 1986, is better known by its original name of Proposition 65. Proposition 65 requires businesses to notify Californians about significant amounts of chemicals in the products they purchase, in their homes or ...

Mitigating Environmental Impact Of Gold Mine Wastewater Through Ozone Oxidation And Aquifer Re-injection
US Environment Protection Agency (USEPA) regulations require mining operations to remediate their waste streams prior to environmental discharge. Wastewater streams from gold mine operations can be particularly toxic due to the potential for cyanide contamination and the concentration of metals contained in the wastewater effluent. This paper reviews the challenges and success of installing and ...
