Clinical waste management in Victorian hospitals

This project for the Doctor of Technology provides a significant contribution to the understanding of healthcare waste management in Victoria and worldwide. The thesis describes approaches to enable healthcare facilities to identify factors that contribute to waste generation and resulting impacts on the environment in order to reduce them.

Gerenciamento dos resíduos sólidos dos serviços de saúde: aspectos do manejo interno no município de Marituba, Pará, Brasil

Os resíduos sólidos dos serviços de saúde (RSSS) oferecem risco potencial para saúde pública e meio ambiente perante um gerenciamento inadequado. Objetivou-se verificar aspectos do manejo interno dos RSSS do município paraense de Marituba. Através da aplicação de questionários e visitas de campo, realizou-se um estudo descritivo, observacional em treze estabelecimentos de saúde. O volume total de resíduos gerados era de cerca de 13.000kg/semana. Havia limitações nas diversas etapas do manejo interno, como a realização de tratamento interno somente num local, o armazenamento externo, que ocorria em quatro instituições e de maneira precária, entre outros. Também, havia conformidades como acondicionamento em sacos e recipientes adequados, segregação dos resíduos comuns. De modo geral, as normas federais não eram atendidas e o gerenciamento de RSSS dos estabelecimentos de saúde necessita de adequação na realização de todas as etapas do manejo, para controlar e diminuir os riscos e reduzir a quantidade de resíduos.

Does my business need generator identification numbers and manifests?

Because you generate waste, it is your responsibility to determine how to properly manage and dispose of your waste. This fact sheet discusses special waste, who must obtain a generator identification number, and who must use uniform hazardous waste manifests, which are required for both nonhazardous and hazardous special waste. ... Depending on the types of waste you generate, you may need a U.S. Environmental Protection Agency (U.S. EPA) and/or Illinois Environmental Protection Agency (Illinois EPA) generator identification number. The first step in determining whether you need an identification number is to identify the types and amounts of waste you generate.

Funding : Australia’s grant system wastes time

We found that scientists in Australia spent more than five centuries' worth of time preparing research-grant proposals for consideration by the largest funding scheme of 2012. Because just 20.5% of these applications were successful, the equivalent of some four centuries of effort returned no immediate benefit to researchers and wasted valuable research time. The system needs reforming and alternative funding processes should be investigated...

Fate and effects of drilling wastes in a shallow estuarine mesocosm

To address concerns expressed about the possible effect of drilling mud discharges on shallow, low-energy estuarine ecosystems, a 12 month study was designed to detect alterations in water quality and sediment geochemistry. Each drilling mud used in the study and sediments from the study site were analyzed in the laboratory for chemical and physical characteristics. Potential water quality impacts were simulated by the EPA-COE elutriation test procedure. Mud toxicity was measured by acute and chronic bioassays with Mysidopsis bahia, Mercenaria mercenaria, and Nereis virens.^ For the field study, a relatively pristine, shallow (1.2 m) estuary (Christmas Bay, TX) without any drilling activity for the last 30 years was chosen for the study site. After a three month baseline study, three stations were selected. Station 1 was an external control. At each treatment station (2, 3), mesocosms were constructed to enclose a 3.5 m$\sp3$ water column. Each treatment station included an internal control site also. Each in situ mesocosm, except the controls, was successively dosed at a mesocosm-specific dose (1:100; 1:1,000; or 1:10,000 v/v) with 4 field collected drilling muds (spud, nondispersed, lightly-treated, and heavily-treated lignosulfonate) in sequential order over 1.5 months. Twenty-four hours after each dose, water exchange was allowed until the next treatment. Station 3 was destroyed by a winter storm. After the last treatment, the enclosures were removed and the remaining sites monitored for 6 months. One additional site was similarly dosed (1:100 v/v) with clean dredged sediment from Christmas Bay for comparison between dredged sediments and drilling muds.^ Results of the analysis of the water samples and field measurements showed that water quality was impacted during the discharges, primarily at the highest dose (1:100 v/v), but that elevated levels of C, Cr (T,F), Cr$\sp{+3}$ (T, F), N, Pb, and Zn returned to ambient levels before the end of the 24 hour exposure period or immediately after water exchange was allowed (Al, Ba(T), Chlorophyll ABC, SS, %T). Barium, from the barite, was used as a geochemical tracer in the sediments to confirm estimated doses by mass balance calculations. Barium reached a maximum of 166x background levels at the high dose mesocosm. Barium levels returned to ambient or only slightly elevated levels at the end of the 6 month monitoring period due to sediment deposition, resuspension, and bioturbation. QA/QC results using blind samples consisting of lab standards and spiked samples for both water and sediment matrices were within acceptable coefficients of variation.^ In order to avoid impacts on water quality and sediment geochemistry in a shallow estuarine ecosystem, this study concluded that a minimal dilution of 1:1,000 (v/v) would be required in addition to existing regulatory constraints. ^
