Temperature programmed oxidation (TPO) is an analytical technique capable of establishing the oxidation of an element or compound through thermal excitation, with various applications in the field of catalysis. The performance of TPO requires a furnace or microreactor capable of increasing temperatures of a catalyst in precise increments up to extreme conditions, for example in brackets of ...
Emissions standards imposed upon auto engineering firms in the US could be set to change, as the Environmental Protection Agency reviews the current standards which have been in place since 2012. The EPA are considering redressing the greenhouse gas emissions standards for light-duty vehicles due for production in the model years 2022—2025, citing changing economic circumstances as the ...
No other research institution in Norway has been paid off so well in EU's fifth framework programme as the Norwegian Institute for Air Research (NILU). 'Norway is of no importance to the Europeans', this is the opinion of Director Øystein Hov. 'It's no use promoting Norwegian special points of view in the ...
Industrial-grade sulfuric acid, still the most widely used industrial chemical in the world, continues to be sourced primarily (about 70 percent) as a nondiscretionary byproduct from the roasting, smelting, and refining of nonferrous metals. The rest comes from natural gas processing, electric power generation, and spent acid regeneration. These industries are usually heavy emitters of ...
There has been a revolution in awareness of chemical air pollution in research laboratories. I could tell you several 'horror stories' of casual exposure to mercury vapour, benzene and chromic acid (the ultimate glassware cleaning agent) among innocent biomedical PhD students (including myself) in the 1970s. But researchers in hospitals, and other laboratories can never afford to be complacent ...
A recent inventory of plastics pollution in the Great Lakes will help prevent continued pollution and provide a baseline for those working to clean the lakes, which supply local residents with drinking water. The Great Lakes Basin is a system of five bodies of water and their tributaries along the northernmost tier of the United States, four of which border Canada. They include Lake Superior, ...
Current research on groundwater vulnerability is aimed mainly at groundwater pollution vulnerability (GPV), and the vulnerability of groundwater quantity is seldom considered. It is important to carry out the groundwater vulnerability evaluation for the management of groundwater resources. This paper presents evaluation models and methods for assessing groundwater quantity and pollution ...
China has experienced dramatic urbanisation and motorisation in the past 20 years. The phenomenal rise in the vehicle population in major cities has resulted in increased air pollution, traffic congestion and other 'wicked problems'. The Chinese government at all levels has made significant effort to control motor vehicle emissions, but vehicle population growth far outpaces their efforts, ...
A universal method to evaluate groundwater pollution risk with the site scale has not been established. The groundwater pollution risk is commonly evaluated by overlaying the results of groundwater vulnerability and pollution sources, but this method is inapplicable for contaminated sites. Considering the current supervision demands of groundwater pollution in China, this paper suggests a risk ...
Persistent organic pollutants (POP) have been subject to research at NILU for a long time. These substances are toxic and are of anthropogenic origin, they accumulate in the environment, and they move through the environment so that after a discharge their traces including transformation products can be found in far-away places in air, water, soil and biological ...
Two big stories from 2014 were the amount of air pollution in cities, especially in China, and the rise of “wearables” and other personal technologies people use to track things about themselves, often having to do with health and fitness measurements, such as steps taken, hours slept, heart rate and more. Now, the ...
The world faces difficult pollution control decisions. For every dollar spent on pollution control, there is an alternative investment in health improvement. For every dollar spent on reducing one pollutant, there is an alternative to reduce another. The most prudent course to make the best investment should include: Intelligent uncertainty Intelligent classification of options ...
It is rare these days that you can be somewhere without noise pollution intruding on some level. Many natural noises may be welcome; a dawn chorus or waves breaking on the beach, but when it comes to man-made decibels it’s a different matter. Never mind the sounds of cars, ring tones and other noises that we take for granted, have you ever noticed how utterly surrounded we are by the humble ...
A new study suggests that exposure to chemical pollution could be a particular problem in the office environment. Researchers in the United States have found a link between Polyfluorinated Compounds (PFCs) in the air of a number of offices and their presence in the blood of the people working there. Polyfluorinated Compounds are water and stain-resistant and they have been used for many ...
The Comet assay is playing an increasing role in studies to determine possible links between environmental pollutants and DNA integrity. The assay is an ideal biomarker for such investigations due to its sensitivity and reliability in detecting DNA damage and repair. Many research groups use our Comet ...
A study connects days with high levels of pollution with myocardial infarctionMore several myocardial infarction happens when pollution levels are higher. A study of cardiologists from Vall d’Hebron demonstrate it Tobacco use, alcoholism, sedentariness, unhealthy diet… The usual bad habits that provoques plaque build-up in the coronary arteries have a new ally, for the first time, ...
Countries around the world are planning to take action against environmental population and other related issues that take place as a result of fossil fuel emissions. In fact, several countries have gone as far as to implement different measures in order to reduce the carbon dioxide pollution. Carbon tax is one such initiative taken by the UK government. ...
Epidemiological research has identified that there exists a correlation between days of high air pollution and the timing of death for large numbers of individuals. Before economic values can be attached to these impacts, however, greater information is required on the extent of life lost and the socio-economic characteristics of those at greatest risk. It may be more fruitful to base willingness ...
