Likely Source of Contamination was Use
This case study involved exposure by an adult with diagnosed multiple chemical sensitivity to contamination in an urban home. The participant had been living in community housing for the past 20 years and was required to move due to the need for major renovations. He moved into a new community housing property that was observed to be very rundown. Every time he visited the property for short periods of time (up to 40 min duration) while taking possessions to the property, he felt unwell. This only occurred when entering the home, even for short periods of time, with the effects lasting after exiting the property for up to a few days. The adverse health effects tended to become continuous with repeated entry into the home. He was suspicious of past activities in the home, believed to be heavy drug use, based on discussions with neighbours. Awareness of potential methamphetamine contamination prompted him to get the property tested. This identified that the property was contaminated. He never completed moving in, however he had to deal with his possessions that had already been moved in and were found to be contaminated.
22 of the 63 participants of this study reported health effects as indicated by levels of contamination reported in the green section of the below chart. This means that the adult who was intending to move into this contaminated property may have suffered: Behavioural Issues, Heachaches, Sleep Disruption, Immune related disorder, Respiratory Issues, Eye issues and Skin irritation.
Note that this person did not completely move into the property and only attended for short periods of time (was not residing full time at the address) yet still suffered the effects. Upon testing of their possessions, (that had been moved into the property) they were found to be contaminated.
The study states; "In terms of health effects reported by participants exposed in contaminated properties, these were consistently reported regardless of the source of the methamphetamine contamination. The only key difference in the health effects reported was a higher prevalence of eye and respiratory issues in properties known or suspected to have been contaminated from manufacture."
