Source apportionment and source/sink relationships of PAHs in the coastal atmosphere of Chicago and Lake Michigan

Multivariate statistical techniques were used to investigate source apportionment and source/sink relationships for polycyclic aromatic hydrocarbons (PAHs) in the urban and adjacent coastal atmosphere of Chicago/Lake Michigan in 1994–1995. The PAH signatures for the atmospheric particle phase, surface water particle phase and sediments indicate that atmospheric deposition is the major source of PAHs to the sediments and water column particulate phase of Lake Michigan. The PAH signature for the atmospheric gas phase and water dissolved phase indicate an intimate linkage between the lake and its overlying atmosphere. A modified factor analysis-multiple regression model was successfully applied to the source apportionment of atmospheric PAHs (gas+particle). Coal combustion accounted for 48±5% of the ΣPAH concentration in both the urban and adjacent coastal atmosphere, natural gas combustion accounted for 26±2%, coke ovens accounted for 14±3%, and vehicle emissions (gas+diesel) accounted for 9±4%. Each is an identified source category for the region. These results are consistent with the mix of fossil fuel combustion sources and ratios of indicator PAHs.

Perspectives on Finland’s sustainable consumption and production policy

The Finnish approach that is starting from the basic human needs of food, housing, mobility and related lifestyles enables us to address the social dimension of sustainable development alongside the ecological and economic dimensions. In this context environmental problems cannot be resolved in isolation from people’s everyday lives, as can happen if environmental policies are based purely on emissions.But it is also worth questioning the potential for national SCP programmes in today’s global markets. Over the last ten years, domestic material flows within the Finnish economy have remained fairly constant, with gains in material efficiency cancelled out by increasing levels of material consumption. However, external material flows and the consequent environmental impacts have steadily increased, and the magnitude and environmental impacts of both imports and exports are approximately the same as for domestic flows. This means that the role of external material flows can no longer be ignored in national SCP policies.It is also important to integrate SCP with climate policies. Finland’s national climate and energy strategy is mainly based on the need to reduce CO₂ emissions from energy production and industrial installations, but there is also a need for complementary actions to reduce the carbon footprints caused by private and public consumption.     

Predicting suitable habitat for the European lobster (Homarus gammarus), on the Basque continental shelf (Bay of Biscay), using Ecological-Niche Factor Analysis

Predicting species distribution and habitat suitability (HS) modelling, across broad spatial scales, is now a major challenge in marine ecology. The resulting knowledge is of considerable use in supporting the implementation of environmental legislation, integrated coastal zone management and ecosystem-based fisheries management. This contribution considers the identification of seafloor morphological characteristics, together with wave energy conditions, that determine the presence of European lobster (Homarus gammarus); and it predicts suitable habitats over the Basque continental shelf (Bay of Biscay), in summer. The results obtained, by applying Ecological-Niche Factor Analysis (ENFA), indicate that lobster habitat differs considerably from the mean environmental condition over the study area; likewise, that it is restrictive in terms of the range of conditions in which they dwell. The best of the environmental predictors found to be: distance to the rock substrate; Benthic Position Index; wave flux over the seafloor; and the underlying bathymetry. A habitat suitability map was produced, with a high model quality (Boyce index: 0.98 ± 0.06). The most suitable habitat for European lobster are locations at the boundary between sedimentary- and rocky-bottoms, coincident with seafloor depressions with a steep slope, with medium to high wave energy conditions, and located within a range of water depths of 35–40 m. This approach demonstrates the applicability of the method in case studies where only presence data are available, together with the inclusion of environmental variables obtained from different sources.     

When and how personality predicts workplace safety: Evaluating a moderated mediation model

Introduction: Though previous research has linked personality and workplace safety, results have been inconsistent. Aims of the present study were to understand when and how personality factors predict safety performance. Methods: With 492 working adults, a moderated mediation model was tested whereby the relationship between personality and safety behavior was mediated by safety motivation and moderated by situation strength (i.e., safety climate perceptions). Results: Findings indicate that, aside from extraversion, safety motivation mediated all relationships between FFM personality traits and safety behavior. The mediated relationship between conscientiousness and safety motivation was attenuated by safety climate perceptions. However, relationships between all other personality traits and safety motivation, and ultimately safety behavior, remained consistent or, in the case of extraversion, was augmented at higher levels of safety climate perceptions. Conclusion: Results demonstrate an empirical basis for how and when personality translates into safety behavior at work. Additionally, findings provide a theoretical explanation for the mixed results among previous studies of personality’s relationship with safety outcomes. Implications are discussed for employee selection and training practices in safety-intensive industries.     

Copper and cadmium effects on growth and extracellular exudation of the marine toxic dinoflagellate Alexandrium catenella: 3D-fluorescence spectroscopy approach

In this study, metal contamination experiments were conducted to investigate the effects of copper and cadmium on the growth of the marine toxic dinoflagellate Alexandrium catenella and on the production of dissolved organic matter (Dissolved Organic Carbon: DOC; Fluorescent Dissolved Organic Matter: FDOM). This species was exposed to increasing concentrations of Cu²⁺ (9.93 × 10⁻¹⁰–1.00 × 10⁻⁷ M) or Cd²⁺ (1.30 × 10⁻⁸–4.38 × 10⁻⁷ M), to simulate polluted environments. The drastic effects were observed at pCu²⁺ = 7.96 (Cu²⁺: 1.08 × 10⁻⁸ M) and pCd²⁺ = 7.28 (Cd²⁺: 5.19 × 10⁻⁸ M), where cyst formation occurred. Lower levels of Cu²⁺ (pCu²⁺ > 9.00) and Cd²⁺ (pCd²⁺ > 7.28) had no effect on growth. However, when levels of Cu²⁺ and Cd²⁺ were beyond 10⁻⁷ M, the growth was totally inhibited. The DOC released per cell (DOC/Cell) was different depending on the exposure time and the metal contamination, with higher DOC/Cell values in response to Cu²⁺ and Cd²⁺, comparatively to the control. Samples were also analyzed by 3D-fluorescence spectroscopy, using the Parallel Factor Analysis (PARAFAC) algorithm to characterize the FDOM. The PARAFAC analytical treatment revealed four components (C1, C2, C3 and C4) that could be associated with two contributions: one, related to the biological activity; the other, linked to the decomposition of organic matter. The C1 component combined a tryptophan peak and a characteristic humic substances response, and the C2 component was considered as a tryptophan protein fluorophore. The C3 and C4 components were associated to marine organic matter production.
