Likely Source of Contamination was Manufacture
This case study related to a rental property in an urban area occupied by a mother and 2 children. At the time of signing the rental agreement, there was no information provided that indicated that the owner of the property had been arrested for the manufacture of methamphetamine. Management of the property was undertaken by the owner’s mother. At the time of rental, the owner’s mother, sister, and letting agent (a friend of the sister) were aware that the property had formerly been used to manufacture methamphetamine, but the tenant was not informed. The owner cleaned the property and replaced curtains prior to letting. Neither the police nor the local council had knowledge of the property in relation to the manufacture of methamphetamine. The tenant became aware of potential methamphetamine contamination as a result of conversations with neighbours, who told them about the former tenant, who received a prison term for methamphetamine manufacture. The tenant was also suspicious of contamination as the tenant’s son’s behaviour was significantly different when living at home compared with times when he spent at least a week out of the home. The tenant had the property tested. Once contamination was discovered and was found to be higher in the lower level (basement) where the tenant’s son resided, the family moved out without their possessions. The local council was notified of the results and they issued a clean-up notice to the owner.
23 of the 63 participants of this study reported health effects as indicated by levels of contamination reported in the purple section of the below chart. This means that the two children and mother residing in this contaminated property may have suffered: Behavioural Issues, Heachaches, Sleep Disruption, Immune related disorder, Respiratory Issues, Eye issues and Skin irritation.
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."
