“…Knox (1990) observed that the levels of alcohols were greatest in fresh refuse, and other studies also found that OVOCs (alcohols, carbonyl compounds, esters and ethers) were principally emitted at the early stage of waste decomposition (Smet et al, 1999;Muezzinoglu, 2003;Chiriac et al, 2011;Kumar et al, 2011;Delgado-Rodríguez et al, 2012) and bio-drying (He et al, 2010). Considering that organic waste is an important component of MSWs, and that municipal wastes may stay in dustbins or transfer into stations up to a week before reaching landfills or incinerators, and their decomposition largely takes place under aerobic conditions during the collection and distribution processes and the early times in landfills (Statheropoulos et al, 2005;Zhang et al, 2012), the results in the present study suggested that considerable amounts of OVOCs are emitted during early disposal of organic wastes and thus contribute to malodor from these waste treatment facilities. Table 1 presents the production of detected OVOCs during the two-month incubation of orange wastes.…”

“…For example, OVOCs accounted for over 98% of volatile compounds extracted from flesh of citrus fruit (Umano et al, 2002). Fruit and vegetable wastes, such as biodegradable wastes, are decomposed initially by an aerobic process in the early stage of disposal (in dustbins and transfer stations, and early in landfills) by consuming oxygen from the air or remaining in the wastes (Statheropoulos et al, 2005;Zhang et al, 2012). Rather than studying OVOC Devos et al (1990).…”

“…VOCs were analysed using thermal desorption/ gas chromatography/mass spectrometry (TD/ GC/M S) on over 150 co mpounds with the 30 most abundant quantified. When waste accumulated in bins under unforeseen circu mstances, some co mpounds produced were likely to exceed olfactory and safety thresholds hence represented potential sources of adverse health impacts [27]. Ben zene and dimethyl d i-sulfide levels determined in this work were found around safety and odour threshold levels.…”

“…Statheropoulos, Agapiou and Pallis [27]examined volatile organic compounds (VOCs) that evolved from urban household waste disposal bins. As part of a case control study, the researchers examined waste of various loads (full, empty, part ially filled bins), remained uncollected in the containers for variable time and under a range of weather conditions.…”

Safety Management of Small-Sized Chemical Waste Treatement Facilities in Victoria, Australia

W ith the increased use of chemicals in industry, facilities for t reating chemical wastes are becoming an important part of the modern society. In Australia, chemical waste treatment facilities are largely small -sized businesses, emp loying less than twenty people. Because of their small size these facilities have generally escaped the attention of regulators, researchers and policy advisors. This is a significant concern because many of these facilit ies may continue to operate with substandard safety practices and, if left unchecked, these facilities are prime candidates for organizat ional disasters and major accidents.This paper discusses the findings of a pilot study investigation undertaken to assess safety management practices across a sample of sma ll-sized chemical waste treatment facilities in the state of Victoria, Australia. Results of this study provide useful informat ion to waste, environment and health and safety advocacy groups, researchers, emp loyees and employers interested in prevention of chemical related incidents, and to government agencies involved in the regulatory administration of safety.

Development of a Dynamic Headspace Concentration Technique for the Non-Contact Sampling of Human Odor Samples and the Creation of Canine Training Aids

Scent evidence is often collected by law enforcement agencies using a Scent Transfer Unit, a dynamic headspace concentration device. The goals of this research were to evaluate the STU-100 for the collection of human scent samples, and to apply this method to the collection of living and deceased human samples, and to the creation of canine training aids.The airflow rate and collection material used with the STU-100 were evaluated using a novel scent delivery method. Controlled Odor Mimic Permeation Systems were created containing representative standard compounds delivered at known rates, improving the reproducibility of optimization experiments.viii Flow rates and collection materials were compared. Higher air flow rates usually yielded significantly less total volatile compounds due to compound breakthrough through the collection material. Collection from polymer and cellulose-based materials demonstrated that the molecular backbone of the material is a factor in the trapping and releasing of compounds. The weave of the material also affects compound collection, as those materials with a tighter weave demonstrated enhanced collection efficiencies.Using the optimized method, volatiles were efficiently collected from living and deceased humans. Replicates of the living human samples showed good reproducibility; however, the odor profiles from individuals were not always distinguishable from one another. Analysis of the human remains samples revealed similarity in the type and ratio of compounds.Two types of prototype training aids were developed utilizing combinations of pure compounds as well as volatiles from actual human samples concentrated onto sorbents, which were subsequently used in field tests. The pseudo scent aids had moderate success in field tests, and the Odor pad aids had significant success. This research demonstrates that the STU-100 is a valuable tool for dog handlers and as a field instrument; however, modifications are warranted in order to improve its performance as a method for instrumental detection.
