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.
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)...
Environmental impact of recycling metals from ships: a life cycle assessment
New research has examined three different categories of Ecological Risk Assessment (ERA), each with different goals. The researchers find that overlaps between the three assessments could be combined to create a more comprehensive form of ERA, usable by regulators and environmental decision makers. Life cycle assessment (LCA) can measure the environmental impact of the different stages of a ship’s life cycle, from design to dismantling. This assessment focused on the impact of recycling the metal parts of a...
