The Use of Atmospheric Dispersion Models in Risk Assessment Decision Support Systems for Pesticides

In the evaluation of potentially adverse effects oforganic chemicals such as pesticides on theenvironment the atmosphere may play an important role.After its release to the atmosphere the chemical willbe transported/dispersed in the atmosphere and finallyit will be removed either by atmospheric-chemicaldestruction or by deposition to the underlying soil orsurface water. In a risk assessment decision supportsystem both ambient concentrations and depositionfluxes must be known to evaluate the risk of directexposure (inhalation) or the risk of soil and watercontamination caused by deposition. This paperdiscusses the use of atmospheric dispersion models insuch risk assessment decision support systems.

Eco-Labelling of Shampoos,Shower Gels and Foam Baths (6 pp)

GOAL, SCOPE AND BACKGROUND: Environmental issues of personal care products have been met with little attention in the past. Monitoring data as well as preliminary environmental risk assessments indicate that some ingredients in personal care products might be relevant pollutants in the environment. Following the precautionary principle, eco-labelling is proposed as an effective tool for source control of one major group of personal care products, shampoos, shower gels and foam baths (SSBs). Eco-labelling is a soft, but effective market driven and product specific approach to lower discharge of environmentally detrimental substances. Products that fulfil the criteria proposed help to minimise the impact of SSBs on the environment. METHODS: Available assessment tools for dangerous substances (e.g. current legislation on environmental risk assessments and classification, and labelling, eco-labelling criteria for similar products, the calculation of the critical dilution volume) were adapted and integrated into the criteria for the eco-labelling of SSBs. RESULTS AND DISCUSSION: A short outline of the eco-labelling criteria developed for SSBs is provided. The basic criteria concern the effects of the substances discharged into the waste water during and after use. Products with an eco-label award may exclusively contain substances for which basic information about their effects on the environment is available. They may not contain persistent, bioaccumulating, toxic or ecotoxicological substances. In addition, the basic criteria include requirements for the container and consumer information. CONCLUSION: The basic criteria for eco-labelling SSBs are based on the actual state of science and are at the same time as simple and transparent as possible to ensure the best applicability. SSBs that comply with the described basic criteria can contribute to a lower chemical burden of waste water treatment plants and surface water. RECOMMENDATION AND OUTLOOK: The proposal for basic criteria described should stimulate discussion on eco-labelling of SSBs. It should help to pass valid criteria supported by authorities, producers and consumer groups for a national or international eco-label, e.g. for the European Flower or the German Blue Angel. In future, the successful introduction of labelled SSBs into the market will raise the awareness of the general public about the environmental effects of personal care products and it will help to promote environmentally compatible products.     

鱼肉结合态MCLR的亚慢性毒性研究

为了揭示含有微囊藻毒素水产品的食用安全性,以雄性BALB/C小鼠为模式生物,通过为期13周的灌胃染毒实验,研究了鱼肉结合态MCLR对小鼠的亚慢性毒性作用,并与水溶态MCLR的毒性进行了对比.结果表明,68.75 μg/kg (以单位体重计)剂量水溶态MCLR可引起小鼠肝脏显著系数增加（P＜0.05）,ALT、AST活性增强（P＜0.01）,引起肝细胞出现有空泡状病变;而肾脏酶学指标BUN、Cr及肾脏组织病理学观察均未发现明显异常;与之相比,同剂量鱼肉结合态MCLR对小鼠各项指标的影响并不明显,仅在实验第1周出现小鼠肝脏肿大（P＜0.05）、ALT活性增强(P＜0.01).由此推断,鱼肉结合态MCLR的毒性低于水溶态MCLR.     

Review of the methods used for isolating pharmaceutical lead compounds from traditional medicinal plants

The possibility of finding new medicines from natural sources is one of the more commonly cited reasons for preserving biodiversity, and employing indigenous knowledge of traditional healing remedies greatly increases the likelihood of discovering these hidden medicinal compounds. The main difficulties in using natural products as a source for pharmaceutical lead compounds involve separating the plethora of compounds from the original extract, as well as the gamble of time and money invested in an activity that may not yield a novel compound. However, while these difficulties exist, the potential of natural products still far outweighs the limitations of the simple structures and known modes of action of synthetic lead compounds. As such, the production of novel medicines, particularly for cancer and human immunodeficiency virus (HIV) treatments as well as the inhibition of antibiotic-resistant bacteria, now requires the utilization of natural products. This paper provides a review of the current methods used in elucidating pharmaceutical lead compounds from natural sources, focusing on plant samples in particular.

The Wild Kangaroo Industry: Developing the Potential for Sustainability

Wildlife resources the world over have long been subject to harvest and management. As wildlife uses have grown, so too have the need and desire to ensure their sustainability. This new context of sustainability presents opportunities to merge ecological, economic and social elements to foster development. This paper presents the management and harvesting of wild kangaroos as an example of the potentially sustainable use of a natural resource. Some comparisons are drawn between the use of other wild living resources, deer in Europe and crayfish in Western Australia. However, sustainability of kangaroo species and the industry is not just a matter of market economics and ecology, it must also be socially sustainable. The public policy instrument of a statutory advisory board with a marketing function is proposed in order to integrate the cultural and social aspects of kangaroo management with the economic and ecological aspects. Through such integration, full sustainability of a wild resource then might be achieved.
