CALRoads View is an air dispersion modeling package that predicts near-roadway air quality impacts from moving and idling vehicles. It integrates three dispersion models: CALINE4, CAL3QHC, and CAL3QHCR. The original design of these models accounted for releases of PM, CO, and NO2 with no support for other inert ...
For example, a chemical plant reactor pressure monitoring uses a model with a range of 0-10MPa, and the data stability is improved by 30% in actual use. ...
Alberta Environment is becoming a policy driven and outcomes focused ministry. A key factor in the success of this strategic shift is being able to effectively monitor and report on the state of the environment. The objective was to demonstrate that the department is achieving its desired environmental outcomes using a systems management ...
Lakes Environmental Software developed Char View for the U.S. EPA to allow modelers to prepare site data, emissions, inventories, and air models quickly while avoiding common human errors in the ...
An environmental management authority in a Caribbean nation recently implemented the Ambient Quality Management Information System (AQMIS) to modernize and centralize its approach to air quality monitoring and management. Designed as a comprehensive platform, AQMIS integrates multiple data streams, analytics, and visualization tools to provide a holistic view of air quality. The system includes ...
Abstract Cannabis is used by an estimated 192 million people around the world. Most people use cannabis through the inhalation of cannabis smoke, which contains combustion by-products that can negatively affect lung health. Knowledge of these risks has led to a growing interest in cannabis vaporizers, which heat the dry cannabis flower without burning. Vaporizing cannabis still releases ...
Atmospheric NO and NOy monitoring during in-flight research missions has become an essential tool for understanding the complex chemistry of the upper troposphere and lower stratosphere. The ECO PHYSICS CLD780TR analyzer plays a crucial role in these measurements, offering high precision and reliability for airborne applications. ...
No pressure drop, low maintenance. Example Models: Endress+Hauser Promag 50W (for wastewater). Siemens Mag 8000 (potable water). 2. ...
Here’s a breakdown of the key contributors to airport air pollution. Studies using AERMOD and CALPUFF dispersion models show that pollutants such as NO2 and PM2.5 have: Higher concentrations near terminals and taxiways due to engine idling and GSE operations. ...
In summer and during heat events, the urban heat island can have a negative impact on human health, leading to adaptation measures for a changing climate being particularly necessary for cities in the context of climate change. Detailed information on the microclimate within cities is required for the planning of efficient adaptation measures. This information can be generated with micro-scale ...
Lakes Software recently announced its acquisition of the CALPUFF modeling system from Exponent. Because Lakes’ CALPUFF View interface is well known throughout the modeling community, some modelers were not aware of the differences between this application and the stand-alone modeling system. This tip will explain the relationship between the modeling system and the CALPUFF View ...
NIWA has pioneered the use of dense air quality sensor networks to uncover block-by-block air pollution patterns within towns across New Zealand. 40 Clarity Node-S solar-powered air quality sensors deployed 3x Higher PM2.5 levels detected in air pollution hotspots compared to cleanest areas 6 km Maximum distance NIWA ...
If you work in mining or with customers in the mining industry, you will be used to finding air operated double diaphragm pumps (AODD) in many of their processes. If this is the case for you, we invite you to read on…In this article you will find:The reasons for choosing pneumatic double-diaphragm pumps in mining.Advantages offered by Samoa Industrial’s pneumatic double diaphragm ...
Established to safeguard the air, water, and land, the MPCA plays a crucial role in monitoring and regulating air quality. ...
HI-Q can meet all of the current industry standards required for our sampling systems. Custom Air Sampler Design For applications that do not fit HI-Q’s standard product line of air samplers, HI-Q can design an air sampler to a Customer provided design specification. ...
In this case study, you’ll learn how Kansanshi Mine improved its compliance monitoring, reduced operational overhead and increased reliability by deploying its first network of Clarity Node-S devices.

The researchers employed a physiologically-relevant in vitro air-liquid interface (ALI) exposure model using the inExpose system to assess the toxicity of different ENDS devices. Murine macrophages (RAW 264.7) were exposed to air, Menthol, or Crème Brûlée-flavored ENDS aerosols for 1 hour per day, over 1 or 3 consecutive days. ...
CALRoads View includes three mobile source air dispersion models: CALINE4, CAL3QHC, and CAL3QHCR. These models are used for predicting air pollution concentrations of carbon monoxide (CO), nitrogen dioxide (NO2), particulate matter (PM), and other inert gases from idle or moving vehicles. The CAL3QHCR model is ...
Interstate air pollution transport refers to pollution from upwind emission sources that impact the air quality in a different state ...
