EU Environmental Policy under Pressure: Chemicals Policy Change between Antagonistic Goals?

Until now, chemicals policy was unable to find a method to establish a sound balance between the benefits and risks of chemical substances. Policy learning within the European Union (EU) resulted in the formulation of an alternative approach to future chemicals policy in some quarters. The Commission's proposal for new chemicals legislation - presented as 'paradigmatic' policy change - led to a highly controversial lobbying debate. This paper deals in particular with the influence of structures, policy networks, multi-level governance and the influence of new modes of governance on chemicals policy-making. It argues that future policy will not represent the paradigmatic change announced by the Commission but only one incremental, cost-effective step towards such a reform. The final proposal is criticised as a neo-liberal interpretation of the Lisbon strategy which includes a dangerous shift in environmental policy making.

Environmental tolerances of free-living coralline algae (maerl): implications for European marine conservation

Maerl is a general term used for loose-lying subtidal beds of nodular coralline red algae. Maerl beds support high associated invertebrate and algal biodiversity, and are subject to European and UK conservation legislation. Previous investigations have shown European maerl to be ecologically fragile due to growth rates of approximately I mm per year. However, these very slow growth rates have hampered attempts to determine the key ecological requirements and sensitivity characteristics of living maerl. In this study, photosynthetic capacity determined by pulse amplitude modulated (PAM) fluorometry was used as a diagnostic of stress caused by various environmental conditions. Maerl species were exposed to a range of temperatures, salinities and light levels and to burial, fragmentation, desiccation and heavy metal treatment. Maerl was not as susceptible as previously assumed to extremes of salinity, temperature and heavy metal pollution, but burial, especially in fine or anoxic sediments, was lethal or caused significant stress. These data indicate that the main anthropogenic hazard for live maerl and the rich communities that depend on them is smothering by fine sediment, such as that produced by trawling or maerl extraction, from sewage discharges or shellfish and fish farm waste, and sedimentation resulting from disruption to tidal flow.

A review of the global pesticide legislation and the scale of challenge in reaching the global harmonization of food safety standards

Pesticide use is important in agriculture to protect crops and improve productivity. However, they have the potential to cause adverse human health or environmental effects, dependent on exposure levels. This review examines existing pesticide legislation worldwide, focusing on the level of harmonisation, and impacts of differing legislation on food safety and trade. Pesticide legislation varies greatly worldwide as countries have different requirements guidelines and legal limits for plant protection. Developed nations have more stringent regulations than developing countries, which lack the resources and expertise to adequately implement and enforce legislation. Global differences in pesticide legislation act as a technical barrier to trade. International parties such as the European Union (EU), Codex Alimentarius Commission (Codex), and North American Free Trade Agreement (NAFTA) have attempted to harmonise pesticide legislation by providing maximum residue limits (MRLs), but globally these limits remain variable. Globally harmonised pesticide standards would serve to increase productivity, profits and trade, and enhance the ability to protect public health and the environment.
