  • Smart cities risk reputation with poor air quality data

    The team at AQMesh continue to receive many enquiries from smart city initiatives and are concerned that integrators risk undermining entire projects by distributing meaningless or misleading air quality information. “Many of the people I speak to are used to dealing with sensors that are easy to ‘plug and play’ and expect to be able to do the same with air quality sensors. This ...

  • 5 Habits that are bad for your indoor air quality

    School is starting, but warm weather means we are still spending more time outside and keeping windows open as much as possible. However, it doesn’t mean we are safe from poor indoor air quality at home. In fact, indoor air may be more polluted in the summer months than in the wintertime. The reasons include high humidity, pollutant buildup, pesticides and VOCs. There are certain habits in ...

  • Air quality in europe 2017

    The Air quality in Europe report series from the EEA presents regular assessments of Europe's air pollutant emissions, concentrations and their associated impacts on health and the environment. Air pollution is a key environmental and social issue and, at the same time, it is a complex problem posing multiple challenges in terms of ...

  • Photodegradation of some brominated and phenolic micropollutants in raw hospital wastewater with CeO2 and TiO2 nanoparticles

    In this study, the degradations of 2,3,4,5,6-pentabromotoluene (PBT), 2,3,4,5,6-pentabromoethyl benzene (PBEB), triclosan (TCS) and gemfibrozil (GFZ) in raw hospital wastewater were investigated with cerium (IV) oxide and titanium (IV) oxide nanoparticles considering the mechanisms of adsorption, photolysis, and photocatalysis with UV-C lamps. The effects of nano-CeO2 and nano-TiO2 ...

  • Modeling for NAAQS Part 1: How to select the appropriate output for NO2

    The U.S. National Ambient Air Quality Standards (NAAQS) for 1-hour SO2, 1-hour NO2, and 24-hour PM2.5 use a very particular format. It is very important for all modelers (both within and outside of the U.S.) to understand how AERMOD handles this. In particular, U.S. users need to be familiar with the ...

  • Critical Monitoring of Forklift Emissions and Warehouse Ambient Air Quality - Case Study

    Our team of experts has been hard at work and has just released an industry-leading report detailing Forklift Emissions in Warehouses: The main objectives of this study were to investigate the effects of different engine conditions on exhaust gas emissions and to observe the effect that forklift emissions have on the ambient air quality of the warehouse.             ...

  • 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?

    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 ...

  • 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 ...

  • Preparation of Fe3O4/TiO2 magnetic mesoporous composites for photocatalytic degradation of organic pollutants

    Fe3O4/TiO2 magnetic mesoporous composites were synthesized through a sol-gel method with tetra-n-butyl titanate as precursor and surfactant P123 as template. The as-prepared Fe3O4/TiO2 composites were characterized by X-ray diffraction, diffuse reflectance spectroscopy, nitrogen adsorption-desorption isotherm and pore size distribution. The ...

  • Clays for heterogeneous photocatalytic decolorization of wastewaters contaminated with synthetic dyes: a review

    Photocatalysis is one of the most environment-friendly and technologically viable advanced oxidation processes. Compared to conventional thermal, biological, and physicochemical treatments, photocatalytic processes have more moderate reaction conditions and higher efficiency. They are a promising technology for the treatment of dye wastewaters, particularly those that have toxic and high ...

  • One-Component Aluminum(heteroscorpionate) Catalysts for the Formation of Cyclic Carbonates from Epoxides and Carbon Dioxide

    Abstract New neutral and zwitterionic chiral NNO-donor scorpionate ligands 1and 2were designed to obtain new mononuclear and dinuclear NNO-heteroscorpionate aluminum complexes. Reaction of 1with [AlR3] (R=Me, Et) in a 1:1 or 1:2 molar ratio afforded the neutral mononuclear alkyl complexes [AlR2(κ2-bpzappe)] {R=Me (3), Et (4); ...

It reviews progress towards meeting the requirements of the air quality directives. An overview of the latest findings and estimates of the effects of air pollution on health and its impacts on ecosystems is also ...

  • 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 ...
