New Zealand is known around the world as a country that is clean, green and “100% Pure.” The existence of genetically modified organisms in New Zealand is generally viewed as inconsistent with this identity, and there is therefore considerable public controversy surrounding research that utilises genetic modification techniques. In this paper, I examine the variety of interacting factors that are serving to shape this controversy, the influence it is having on research practices, and the implications for future risk management policy.

The presence of emerging contaminants in municipal wastewaters, particularly endocrine-disrupting compounds such as oestrogenic substances, has been the focus of much public concern and scientific attention in recent years. Due to the scientific uncertainty still surrounding their effects, the Precautionary Principle could be invoked for the interim management of potential risks. Therefore, precautionary prevention risk-management measures could be employed to reduce human exposure to the compounds of concern. Steroid oestrogens are generally recognized as the most significant oestrogenically active substances in domestic sewage effluent. As a result, the UK Environment Agency has championed a ‘Demonstration Programme’ to investigate the potential for removal of steroid oestrogens and alkylphenol ethoxylates during sewage treatment. Ecological and human health risks are interdependent, and ecological injuries may result in increased human exposures to contaminants or other stressors. In this context of limiting exposure to potential contaminants, examining the relative contribution of various compounds and pathways should be taken into account when identifying effective risk-management measures. In addition, the explicit use of ecological objectives within the scope of the implementation of the EU Water Framework Directive poses new challenges and necessitates the development of ecosystem-based decision tools. This paper addresses some of these issues and proposes a species sensitivity distribution approach to support the decision-making process related to the need and implications of sewage treatment work upgrade as risk-management measures to the presence of oestrogenic compounds in sewage effluent.

Completou-se 30 anos do desastre com o Césio 137, ocorrido na cidade de Goiânia, considerado o maior desastre radioativo do mundo, fora de usinas nucleares. O descarte indevido de um aparelho de radiografia contendo uma cápsula de Césio 137 conjugada a falta de conhecimento e informação sobre as propriedades do material gerou este acidente sem precedentes. O desastre atingiu direta e indiretamente milhares de pessoas, com danos inclusive transtemporais. O objetivo deste artigo é apresentar os fatos que ensejaram o desastre e, por outro lado, ressaltar a importância do acesso à informação para uma efetiva gestão dos riscos. Diante disso, como metodologia se utilizará a pesquisa bibliográfica e a matriz sistêmico-construtivista, demonstrando o funcionamento sistêmico da sociedade, a velocidade das transformações do mundo globalizado, e, portanto, as incertezas e riscos gerados com os quais a comunidade não está suficientemente preparada para enfrentar, o que demanda uma adequada gestão de riscos para a prevenção de desastres.

Abstract Conditions and evidence continue to evolve related to the prediction of the prevalence of immunodeficiency-associated long-term vaccine-derived poliovirus (iVDPV) excreters, which affect assumptions related to forecasting risks and evaluating potential risk management options. Multiple recent reviews provided information about individual iVDPV excreters, but inconsistencies among the reviews raise some challenges. This analysis revisits the available evidence related to iVDPV excreters and provides updated model estimates that can support future risk management decisions. The results suggest that the prevalence of iVDPV excreters remains highly uncertain and variable, but generally confirms the importance of managing the risks associated with iVDPV excreters throughout the polio endgame in the context of successful cessation of all oral poliovirus vaccine use.
