The dramatic decline in the number of elected Democrats, especially the loss of the majority in the House of Representatives, will make for some significant differences in the prospects for the U.S. Environmental Protection Agency’s budget, legislative proposals and general operations.
How to Make a Positive Impact on the Environment This Earth Day
This Saturday, April 22, 2017, marks the 47th annual Earth Day. Earth Day was founded by US Senator Gaylord Nelson, who was concerned that environmental issues were not being addressed. He created the first Earth Day on April 22, 1970, as an educational “teach-in,” with celebrations taking place at universities, primary and secondary schools, and communities across the United States. It is thought that over 20 million people participated in events that day. In 1990, Earth Day became a worldwide event,...
Mosul battle brings environmental damage, with serious impacts on health, prospects of recovery
Civilians in Northern Iraq are falling victim to additional suffering - including near suffocation and respiratory illnesses - due to what appears to be a scorched-earth policy employed by retreating ISIL militants following the launch of a major military offensive to retake the city of Mosul. Nineteen oil wells have been set ablaze by armed groups near Al Qayyarah, located south-east of Mosul, with citizens and armed forces exposed to toxic fumes. The burning crude oil produces a wide range of pollutants,...
Impact of Corrosion on Electronic Equipment
Corrosion is the destruction of metals through reaction with compounds in their environment. It is a natural process because compounds such as oxides, sulphides and chlorides are formed and these are stabler than pure metals. Electronic circuits and components are omnipresent in our environment. Until recently, the thousands of soldered joints that an electronic circuit contains were made with products that contained lead, an element that is highly toxic. Because of the introduction of RoHS regulations that...
Environmental impacts of ocean-energy systems: a life-cycle assessment
Ocean-energy technologies — which harvest renewable energy from the sea — will have a significant role to play in a future low-carbon society. A recent life-cycle analysis of different ocean-energy devices has found that life-cycle environmental impacts are caused mainly by the materials used in the mooring, foundations and structures. Improving the efficiency and lifespan of the devices, as well as improving mooring and foundations and deploying devices further out at sea, will help to further reduce...
Impact of pH on Derivatization of Nitrophenol Compounds
Our goal of evaluating the Normalized French Environmental Method 12673 required testing the method’s ability to derivatize nitrophenols and alkylphenols in addition to the chlorophenols the method was designed for. Unfortunately, nitrophenols proved challenging to derivatize at low concentrations. In an effort to improve the derivatization of nitrophenols, we experimented with the pH of the reaction mixture. The original method requires 5 mL of 1 molar potassium carbonate (0.7 g solid potassium carbonate)...
