The effect of surface charge, negative and bipolar ionization on the deposition of airborne bacteria

S. Meschke et al. – Journal of Applied Microbiology – Fall 2008

Bioaerosols can be generated by several means in an indoor setting, such as the ventilation or air conditioning systems, dust or shed skin disturbance, coughs and sneezes, among others. Although the contribution of air-borne micro-organisms to hospital or clinical-acquired infection has been the source of much debate in recent years, there is evidence suggesting that bioaerosols may play a greater role than previously believed….

Aerosol Surface Disinfection in a Pandemic World: Gas/Vapor-Phase Biocides, Fogging, and Electrostatic Spraying

Eugene C. Cole, DrPH – The Cleaning Industry Research Institute – Summer 2020

In the midst of the current human coronavirus pandemic, many building cleaning and sanitation practices and protocols have been improved in quality and frequency; they have also been upgraded from the use of anti-bacterial sanitizer products to more broad-spectrum disinfectants, capable of inactivating a variety of bacterial, fungal, and viral human pathogens. That has raised the question of the effectiveness of those disinfectants as gas-phase, vapor-phase, or fogging biocides because disinfection via the aerosol route can readily reduce the time and cost of application. The question remains, however: Can aerosol disinfection achieve the same or higher level of infectious disease risk eduction as the manual application of those products?….

The Science of Sewage

Eugene C. Cole, DrPH – The Cleaning Industry Reasearch Institute – Fall 2018

Community wastewater has never been more hazardous. Thus, those impacted by sewage backflows or sewage-contaminated flood waters, as well as those who are engaged in the remediation of sewage contamination, require the latest science-based information necessary to implement appropriate approaches to health protection….

ATP as a Marker for Surface Contamination

Eugene C. Cole, DrPH – Journal of Occupational and Environmental Hygiene – Spring 2013

School environments are a particular concern related to adverse health effects, as well as the potential for poor indoor environmental quality, which can compromise the learning process of students…. ATP has historically been used successfully as an important marker for the detection and quantification of pollutant loads of biological origin and overall cleanliness in the food production and food service industries, and it had been recently confirmed as a representative marker for detection of levels of surface contamination in hospital settings….

Suggested Practice of Remediation of Highly Infectious Biological Agent Contamination in Indoor Environments

Eugene C. Cole, DrPH – Applied Biosafety – 2001

Basic procedures to follow and precautions to observe when performing the remediation and restoration of nonlaboratory indoor environments known or suspected of harboring contamination from potentially infectious biological agents, especially those recognized as being easily aerosolized and thus presenting an inhalation risk.

IAQ Radio – Interview with Dr. Gene Cole

IAQ Radio – April, 2019

LRC’s director of research, Dr. Gene Cole, was recently interviewed on IAQ Radio; where they discuss water damage, sewage, mold, and public health.

IAQ Radio is a show designed to help promote education and communication for industry professionals and consumers in need of assistance with IAQ, built environment, and disaster restoration issues.
