Sediment Contaminants

Long-term variations of ecological status in a Mediterranean coastal lagoon (Sacca di Goro, Northern Adriatic) were investigated, combining data on the concentration of surface sediment contaminants and on the structure of the macrobenthic community. The aim was to assess any amount of chemical contamination and check the response of the macrobenthic community to sediment contamination. Over the studied period, the sediments of the lagoon showed contamination by trace metals and organochlorine pesticides, with most of them exceeding the thresholds indicated by the Italian legislation in many samples. Contamination by polychlorinated dibenzodioxins and dibenzofurans (PCDD/Fs) and polycyclic aromatic hydrocarbons (PAHs) instead never exceeded the threshold. The ecological status based on the macrobenthic community, evaluated through biotic indices (AMBI and M-AMBI), fell below the Good/Moderate threshold in most samples. The results indicate a possible influence of toxic compounds in sediment on benthic organisms, but most of the variability shown by the macrobenthic community is probably due to other factors. The difficulty in establishing a cause/effect relationship was due to the co-occurrence and variability of various stressors (both natural and anthropogenic) and their interactions. The methods currently used for monitoring transitional waters thus seem insufficient to disentangle the effect of pollutants and other environmental variables on the benthos. Integrated approaches (e.g., bioaccumulation and toxicity tests) are thus needed for a more precise identification of the risk posed by a high concentration of pollutants in such environments.

Abstract. Introduction: While alcohol treatment predominantly focuses on abstinence, drug treatment objectives include a variety of outcomes related to consumption and quality of life. Consequently harm reduction programs tackling psychoactive substances are well documented and accepted by practitioners, whereas harm reduction programs tackling alcohol are under-researched and met with resistance. Method: The paper is mainly based on key-person interviews with eight program providers conducted in Switzerland in 2009 and up-dated in 2015, and the analysis of reports and mission statements to establish an inventory and description of drinking under control programs (DUCPs). A recent twin program in Amsterdam and Essen was included to exemplify conditions impeding their implementation. Firstly, a typology based on the type of alcohol management, the provided support and admission criteria is developed, complemented by a detailed description of their functioning in practice. Secondly, the case studies are analyzed in terms of factors promoting and impeding the implementation of DUCPs and efforts of legitimize them and assess their success. Results: Residential and non-residential DUCPs show high diversity and pursue individualized approaches as the detailed case descriptions exemplify. Different modalities of proactively providing and including alcohol consumption are conceptualized in a wider framework of program objectives, including among others, quality of life and harm reduction. Typically DUCPs represent an effort to achieve public or institutional order. Their implementation and success are contingent upon their location, media response, type of alcohol management and the response of other substance-oriented stake holders in the treatment system. The legitimization of DUCPs is hampered by the lack of evaluation studies. DUCPs rely mostly – also because of limited resources – on rudimentary self-evaluations and attribute little importance to data collection exercises. Conclusions: Challenges for participants are underestimated and standard evaluation methodologies tend to be incompatible with the rationale and operational objectives of DUCPs. Program-sensitive multimethod approaches enabled by sufficient financing for monitoring and accompanying research is needed to improve the practice-oriented implementation of DUCPs. Barriers for these programs include assumptions that ‘alcohol-assisted’ help abandons hope for recovery and community response to DUCPs as locally unwanted institutions (‘not in my backyard’) fuelled by stigmatization.
