  • What is Indoor Air Quality?

    Indoor Air Quality (IAQ) refers to the degree of air purity inside buildings that constitute the usual environment in which people carry out activities (offices, homes, schools, shopping and leisure centres, etc.) Because of increasing urbanisation and our contemporary lifestyle, most people spend a large proportion of their time in these closed environments. The high level of atmospheric ...

  • The Chemical Route to a Carbon Dioxide Neutral World

    Excessive CO2 emissions in the atmosphere from anthropogenic activity can be divided into point sources and diffuse sources. The capture of CO2 from flue gases of large industrial installations and its conversion into fuels and chemicals with fast catalytic processes seems technically possible. Some emerging technologies are already being demonstrated on an industrial scale. Others are still ...

  • What is Indoor Air Quality and How Can You Improve It?

    For the longest time, air quality was meant to refer to the quality of air circulating outdoors. However, indoor air or the air found inside and around homes and office buildings is just as important to pay attention to. Improving indoor air quality should be a priority for everyone.  What is Indoor Air Quality? Indoor air quality is the quality of air found circulating ...

  • Biomass is Carbon Neutral – What Does This Mean for Sustainability?

    The topic of climate change is not without its fair share of controversy, and while there are dozens of conflicting scientific and political perspectives at play, one positive that has emerged from the chaos is that the average global citizen is far more aware of the importance of sustainability and environmental responsibility than perhaps ever before. This has trickled into the realm of ...

  • 4 Signs Of Poor Indoor Air Quality To Watch For

    The quality of indoor air is something most of us take for granted. Unless there is something very specific and unusual going on around us, like heavy cleaning or maybe new construction, we don’t often think about whether or not there is anything wrong with the air we breathe as we go about our daily business. The truth is, though, that indoor air quality is often worse than ...

  • The challenges and benefits of local air quality monitoring

    A new generation of air quality monitors is now being offered to provide localised, real-time air quality readings – but the potential benefit is only just starting to be realised. It is generally accepted that whilst measurements from air quality reference stations are highly accurate, they are not sufficiently location-specific. Key pollutants – such as NO2 and PM2.5 ...

  • How air pollution affects office workers—and the economy

    FOR anyone who has tried jogging through smog, the physically sapping impacts of air pollution should come as no surprise. But pollution doesn’t just slow down runners, it hampers workers too. Research by Tom Chang of the University of Southern California and colleagues found that pear packers working indoors were slowed by air pollution even at levels well below current air-quality ...

  • 5 Things You Probably Didnt Know About Indoor Air Quality

    Did you know that air fresheners, candles, furniture, carpets & many other items create indoor air pollutants and are a health risk says Camfil Air Filtration Experts! When you mention air pollution, most people automatically think of smog around cities and factories, or millions of cars racing from one place to another leaving trails of fumes behind them as they ...

  • How to Get Higher Acceptable Indoor Air Quality Anywhere

    The quality of the indoor air we breathe is a concern for everyone, especially those in urban environments where contaminant and particle levels are higher due to nearly constant exposure to things like automobile and truck exhausts, construction, and fumigation. Unfortunately for most people, when it comes to the quality of the air in the buildings where they spend most of their time, ...

  • Evaluation of flow-rate dynamics in the simultaneous photocatalytic treatment of multichlorinated substituted phenols in continuous-flow systems

    The project investigated the simultaneous degradation of chlorophenols dissolved in aqueous systems. The photocatalysis advanced oxidation process was the technology applied to achieve treatment. Chemical behavioural tracking was performed using the chloride dehalogenation sequence dynamics. The study recorded reductive dehalogenation chemical transformation kinetics of multi-substituted ...

  • Removal of naphthalene from offshore produced water through immobilized nano-TiO2 aided photo-oxidation

    In order to increase the applicability of photocatalysis in treating offshore produced water (OPW), an immobilized catalyst was introduced into the UV irradiation system and its performance on the degradation of organic compounds in OPW was evaluated. Naphthalene was selected as the target pollutant owing to its abundance in produced water and its chemical property as a typical polycyclic ...

  • Photocatalysis assisted by peroxymonosulfate and persulfate for benzotriazole degradation: effect of pH on sulfate and hydroxyl radicals

    Recently, notable attempts have been devoted to removing emerging pollutants from water resources. Benzotriazole (BTA) as an emerging pollutant has widely been detected in the aquatic environment and water resources. In the current work, peroxymonosulfate (PMS) and persulfate (PS) were added to a TiO2/UV system for BTA degradation, as electron acceptors to overcome recombination of hole and ...

  • Photocatalytic degradation of MC-LR in water by the UV/TiO2/H2O2 process

    The ultraviolet (UV)/titanium dioxide (TiO2)/hydrogen peroxide (H2O2) process (UTHP) has been proven to be effective in removing organics because of its high production of free radicals. In this study, UTHP was further investigated for the photocatalytic degradation of microcystin-LR (MC-LR). Results showed that three mechanisms could realize MC-LR photocatalytic degradation ...
