Australia’s Tyranny of Distance in Oil Spill Response

In view of the quantity of oil spilled, smaller spills generally receive less attention than headline grabbing incidents such as the “Amoco Cadiz”, “Exxon Valdez”, “Braer” and “Sea Empress”. The latter incidents involve the loss of significant quantities of oil, the establishment of relatively complex spill response management structures and the involvement of significant numbers of personnel and equipment. As such, large spills from tankers have the potential to create problem areas, for example in establishing and maintaining effective communications, logistics and resource management systems.In general terms spill response personnel are well aware that large spills come complete with significant operational and administrative problems, however what may not be so well recognised is that smaller spills also have the potential to present response personnel with their own unique problems.One of the major problems to be overcome when responding to spills in Australia is the “tyranny of distance”. In quite a few responses, Australian oil spill response managers have had to move personnel and equipment thousands of kilometres to provide an effective outcome. This paper outlines a range of problems that have been encountered by Australian personnel over the years. These include health and safety, communications, logistics and equipment issues.For the purpose of this paper a “smaller” spill has been defined as one involving a discharge of less than 1000 tonnes of oil.     

Japan’s waste management policies for dioxins and polychlorinated biphenyls

We summarize the measures taken by the Japanese government to prevent the emission of dioxins and polychlorinated biphenyls (PCBs) into the environment. Because incineration is the main method of waste management in Japan, reducing the amount of dioxins emitted from waste incinerators is an essential aspect of proper waste treatment. Intensive measures to prevent the formation of dioxins at the source have been implemented, with a focus on waste treatment methods and improving comprehensive management. The efforts have been very successful, with a 95% reduction in the amount of dioxins emitted between 1997 and 2003. The toxicity of PCBs has been monitored with keen interest since the Yusho incident. Unfortunately, treatment facilities for PCB wastes were not built until long after PCBs had been removed from use, and PCB wastes remained in storage in an untreated state. The Japanese government has promoted the construction of facilities for treating PCB wastes, and five such facilities have commenced operations. To more completely eradicate dioxins, a future challenge will be to reduce the amount of PCB-derived dioxins, which are persistent in the environment and have a long exposure pathway from the environment media to the organism and the human body.     

Conjugation of Soybean Oil and It’s Free-Radical Copolymerization with Acrylonitrile

The conjugated soybean oil was synthesized through the isomerization reaction of soybean oil to transformed the structure of linoleic acid into conjugated linoleic acid structure, and Rhodium complexes (RhCl(Pph₃)₃) was used as catalyst. The efficiency on the conjugation of catalyst RhCl (Pph₃)₃, tin dichloride dehydrate (SnCl₂·2H₂O) and triphenylphosphine (Pph₃) were evaluated. The results showed when RhCl(Pph₃)₃, SnCl₂·2H₂O and Pph₃ are 9.25, 9.0 and 13.1 mg in 100 g soybean oil respectively, the highest conversion of conjugation achieved 96%. The free radical copolymerization of conjugated soybean oil with acrylonitrile (AN) and dicyclopentadiene (DCP) was studied. AIBN was used as the initiator. FT-IR and ¹H-NMR results indicates that the conjugated soybean oil with AN and DCP did occur free radical copolymerization with the initiator AIBN. The product is light yellow powder. The thermal properties of the soy-based copolymer were investigated by TG and DSC. The initial degradation temperature of polymers is higher then 250 °C.

Community Expectations – Indigenous People’s View. A Cape York Perspective

The paper discusses the priority of maritime estates for Aboriginal people along the coasts of Cape York. These estates restrict Aboriginal use and particular protocols are required to access particular areas. Oil spills could be catastrophic for such traditional arrangements and potentially could destroy the entire coastal resource of particular Aboriginal groups. Concerns about navigation safety are expressed and methods of reducing the risks suggested. If given the choice it is highly probable that Aboriginal people would opt for removing spill threats altogether in the light of minimal benefits derived by their communities.

Determination of Microorganisms’ Attack on Some Flexible Polymers by Using Soil Burial Test Method

Many controversial issues have recently been associated with plasticized poly(vinyl chloride) (pPVC) used in building applications, mainly for flooring. One of them has to do with the health impact of some plasticizers and thermal stabilizers based on heavy metal compounds. Recent advances in the synthesis of polyolefins based on metallocene catalysts can yield similar flexibility for formulations as is now available for those based on pPVC. Polyolefin copolymers are considered to be possible replacements for pPVC. The soil burial test has demonstrated that highly filled polyolefin elastomer formulations having a significant percentage of post-consumer polyolefins (up to 60% in laboratory conditions) have interesting properties from the biodegradation point of view. They are more resistant to microorganisms’ attack than plasticized flooring formulations based on PVC that are currently used, even in a very harsh environment as soil, where complex mixtures of microorganisms are present. The effect of microorganisms’ attack after soil burial was evaluated by visual examination, weight loss, water absorption and changes in mechanical properties.     

Chronic toxicity of the ‘water-soluble fraction’ of Norman Wells crude oil to juvenile fish

Young rainbow trout were exposed to Norman Wells crude oil for periods as long as 55 d. Mortality was light for the first few days, but it continued throughout exposure with more rapid and increased mortality at the higher exposure levels. The mortality was generally exacerbated by the presence of oil dispersants Corexit 7664 or 9600. Fish surviving the 55-day experiment showed severe fin erosion and apparent ‘flooding’, since mean body water content was increased from about 84% to over 90%. We hypothesize that the oil affected the ability of the fish to regulate their water content.

A survey on municipal solid waste and residents’ awareness in Da Nang city, Vietnam

A survey on solid waste generation and residents’ awareness was conducted in Da Nang city, Vietnam in 2010. We took samples from residents, hotels, restaurants, and city markets. Data reveals that each resident generates on average 0.71 kg/capita/day (3 kg/household/day). Regarding the composition, organic waste (food, flowers, leaves, grass) accounts for about 70 % of residents’ waste followed by plastics. Likewise, about 14 % of residents’ waste can be recycled. Furthermore, we find that middle income households in the suburbs have the largest waste generation with 4.9 kg/household/day. We consider that this finding is explained by their dedication to agricultural activities, such as planting fruit trees and vegetables, and gardening. Finally, we find that only about 60 % of interviewees have knowledge of how to segregate waste, however more than 90 % of them are willing to cooperate with the introduction of a waste segregation program in the city.

Preliminary Studies on Converting Agricultural Waste into Biodegradable Plastics,Part I: Corn Distillers’ Dry Grain

Distillers dry grain (DDG) was derivatized either by carboxymethylation, glutaration, maleiation, phthallation, or succination in order to produce anionic materials suitable for complexation with soy protein isolate. Infrared spectroscopy confirmed that derivatization of DDG by all reagents was successful. Blending of derivatized anionic products with soy protein resulted in instant precipitation of gels. The gels were centrifuged, molded, and dried into solid pellets with tensile strengths as high as 1.67MPa, suggesting that these materials could be promising as biodegradable structural materials. Infrared spectroscopy suggested the possibility of complexes forming between soy protein isolate and each of the derivatized DDG samples.

Hydrogeological Basis for Biotechnological Remediation of the Acidic Mining Lake ‘RL 111’, Lusatia (Germany)

The drainage basin of the acidic mining lake RL 111 was characterized by hydrogeological and geochemical models to assess its influence on a planned biotechnological remediation of the lake water and lake sediment. Ground, seepage and lake water, as well as the surrounding sediments, were examined to model the hydrodynamic processes and the geochemical developmentof the lake. The geochemical conditions seem to behave in a stable manner (steady state conditions). A reduction of the high sulphate andacid input has not been observed since the beginning of our investigations. The biotechnological remediation of the whole lake should consider a treatment of the dump sediments to improvethe quality of the inflowing groundwater, as well as to reduce erosion.
