Prescribed burn smoke impact in the Lake Tahoe Basin: model simulation and field verification
Smoke dispersion modelling based on the Fire Emission Production Simulator and the Hybrid Single Particle Lagrangian Integrated Trajectory (FEPS-HYSPLIT) model was applied to prescribed burns in the Lake Tahoe Basin (LTB) during fall 2011. This, in conjunction with measurements at sources and real-time ambient PM 2.5 monitoring around LTB, served to evaluate the prescribed burning impacts on ...

Air Quality Monitoring for Wildfire Smoke
Protecting public health during wildfires In the face of climate change and increasing environmental disasters like wildfires, there is a growing need for resilient air quality monitoring infrastructure. Traditional air quality monitors often rely on vulnerable infrastructures like WiFi and electrical grids, which can easily fail during disasters, leaving us without accurate information about air ...

Construction of a low–cost laser–based multiplexed spectrometer: a potential probe for environmental pollution monitoring
A low–cost, sensitive, laser–based (Helium Neon; He–Ne) optical Fourier–transformed (multiplexed) spectrometer has been constructed for the quantification of suspended particulates in the air. The optomechanical features of the spectrometer are presented together with a theoretical framework of its operation. The apparatus is calibrated by using a standard commercial spectrophotometer and has ...

Air Pollution Part 4 – Reduction Methods
With all said about emissions of pollutants in preceding blogs, it should also be noted that there are multiple methods available and in frequent use to reduce the emissions at their sources, both of gaseous substances and particulates. Addressing Particulates To start with the latter, there are cyclones, electrostatic filters, and fabric filters that can catch the particles before being ...

New England Charcuterie Reduces Product Loss with MadgeTech - Case Study
BACKGROUND Located in Waltham, Massachusetts, New England Charcuterie was established in 2013 as a small processing space in the back of its sister company, Moody’s Delicatessen & Provisions. In 2016, New England Charcuterie moved to a much larger facility across town where they specialize in producing a wide range of meats that combine old world traditions with new world flavors. ...

Status of black carbon monitoring in ambient air in Europe
Black carbon (BC) is increasingly discussed in science and environmental policy areas as an example of an air pollutant that affects both human health and contributes to climate change (e.g. WHO, 2012; UNEP/WMO, 2011; Bond et al., 2013; IPCC, 2013). In order to be able to make comparable measurements of BC in ambient air and to relate BC monitoring to health impacts and climate change it is ...

Real-Time Measurement of Outdoor Tobacco Smoke Particles
ABSTRACT The current lack of empirical data on outdoor tobacco smoke (OTS) levels impedes OTS exposure and risk assessments. We sought to measure peak and time-averaged OTS concentrations in common outdoor settings near smokers and to explore the determinants of time-varying OTS levels, including the effects of source proximity and wind. Using five types of real-time airborne particle ...

How does GWT Solve Problems of UF Water Purification to Optimize this Process?
In one of the previous articles on ultrafiltration, we had talked about some of the common problems associated with UF water purification. Some of these issues are avoidable and others can be mitigated with proper system management. Knowing how to deal with such problems is key to optimizing a membrane filtration process. When designing ultrafiltration systems, it is imperative to keep these ...

Breathing Easy: How Cutting-Edge Monitoring Tech Ensures Air Quality and Health
There is no shortage of research papers highlighting the negative impacts of air pollution on humans and the environment. Everyone, including older adults and little children, suffers the adverse consequences of air pollution. As a result, it is essential to ensure one takes all possible measures to maintain good air quality in their environment. One good way to realize this goal is by monitoring ...

Wildfire Smoke and Headaches: How it is Related?
Wildfires are a destructive force of nature, leaving a trail of ecological devastation in their wake. However, their impact extends beyond the scorched earth and damaged ecosystems; wildfires also threaten human health. In this comprehensive look into the health effects of wildfire smoke, our primary focus will be on one of the most distressing symptoms: headaches. Headaches may seem trivial ...
