Correlation of Traffic Noise Parameters in Queensland

The current available approaches for predicting road traffic noise level indicators rely solely on Linear Regression models that use either LA10(18H) or LA10(1H) as an input variable. This paper extends the prediction scope of regression models to include important indicators and additional road traffic factors as input variables and compares the performance of several machine learning regression methods.

Development of a venting management procedure for container fumigation operations

Container fumigation is frequently undertaken for quarantine and pre-shipment purposes. The process ensures that a commodity is free from pest and disease prior to export or import. Due to the hazardous nature of the chemicals used (such as methyl bromide and phosphine), physical air emission controls such as carbon filtration are required to minimise air quality impacts.

Health risk assessment methodology and environmental justice analysis using HHRAP

This study examines the utility of one HHRA methodology, the U.S. EPA Human Health Risk Assessment Protocol (HHRAP). It builds on a previous paper which evaluated the HARP risk assessment tool for similar purposes. HHRAP was developed by U.S. EPA to provide a means of simulating the risk caused by multi-pathway (air, soil, water, food, etc.) exposure to more than 200 air pollutants.

Measurement of fugitive emission capture efficiency

Fugitive emissions of odour and other pollutants from inside structures provide many challenges for monitoring, modelling and control. This paper presents an example assessment of effectiveness of capture inside a structure containing liquid waste.

Should back-yard firepits be allowed?

This study analyses the various fire pit regulations in Southeast Queensland’s local government areas, and examines potential impacts of fire pits compared to other sources of smoke from wood combustion.
