This special issue of the Journal of Cleaner Production was initiated as a result of the 5th and 6th meetings of the Asia Pacific Roundtable for Sustainable Consumption and Production (APRSCP), which were held in Melbourne, Australia and Hanoi, Vietnam, respectively. A need identified at those meetings was to create another means of communicating the best ideas and papers being presented, to a wider audience. The Asia Pacific region has special development needs given its rapid emergence as a global production hub, but coupled to that are also the rapid social adjustments and shifts in patterns of consumption and production which aren't positive for the environment. This special issue contains eight papers covering the implementation of cleaner production and life cycle principles at the systems and regional planning level. These articles cover urban development, corporate CP programs, supply chain management, eco-industrial networks, and industrial parks, recycling, and understanding the role of human factors in bringing about environmental change. 相似文献

Powdery materials such as metallic or polymer powders play a considerable role in many industrial processes. Their use requires the introduction of preventive safeguard to control the plants safety. The mitigation of an explosion hazard, according to the ATEX 137 Directive (1999/92/EU), requires, among other things, the assessment of the dust ignition sensitivity. PRISME laboratory (University of Orléans) has developed an experimental set-up and methodology, using the Langlie test, for the quick determination of the explosion sensitivity of dusts. This method requires only 20 shots and ignition sensitivity is evaluated through the E50 (energy with an ignition probability of 0.5). A Hartmann tube, with a volume of 1.3 l, was designed and built. Many results on the energy ignition thresholds of partially oxidised aluminium were obtained using this experimental device (Baudry, 2007) and compared to literature. E50 evolution is the same as MIE but their respective values are different and MIE is lower than E50 however the link between E50 and MIE has not been elucidated.In this paper, the Langlie method is explained in detail for the determination of the parameters (mean value E50 and standard deviation σ) of the associated statistic law. The ignition probability versus applied energy is firstly measured for Lycopodium in order to validate the method. A comparison between the normal and the lognormal law was achieved and the best fit was obtained with the lognormal law.In a second part, the Langlie test was performed on different dusts such as aluminium, cornstarch, lycopodium, coal, and PA12 in order to determine E50 and σ for each dust. The energies E05 and E10 corresponding respectively to an ignition probability of 0.05 and 0.1 are determined with the lognormal law and compared to MIE find in literature. E05 and E10 values of ignition energy were found to be very close and were in good agreement with MIE in the literature. 相似文献

The aim of this study is to investigate the trace elements (TE) contents of potential biomonitors in a historical Zn–Pb mining district: apiary products (honey, royal-jelly and beeswax) lichen and moss were sampled and analysed. In spite of high TE concentrations in mining waste and soil, apiary products are free of TE contamination originating from historical mining. Lichen/moss show high TE levels, which suggest atmospheric input of local dust. Pb isotopes analysis proved the origin of TE found in lichen/moss to be mainly mining waste. These results help discuss the choice of relevant organisms for monitoring TE in the environment and bring additional data on the potential impacts of brownfields left after mining, especially on food products from apiaries. 相似文献

Recruitment is essential for the maintenance of populations, but far more is typically known about the more easily-observed
adult stages than their smaller, often microscopic early life-history counterparts. This discrepancy can be particularly problematic
for populations of foundation species that create biogenic habitat for a multitude of other taxa, but are themselves prime
candidates for exploitation, fragmentation, and loss, and therefore become the focus of restoration efforts partly or fully
dependent on recruitment. The purpose of this study was to improve ecological understanding for early life-history stages
of the habitat-forming marine alga Cystoseira barbata (Stackhouse) C. Agardh (Fucales: Sargassaceae), member of a genus that has experienced considerable fragmentation and population
decline on European coasts. Using experimental manipulations of water temperature, light intensity, and sediment accumulation,
we observed that sediment virtually precluded recruitment of C. barbata, and greatly impacted the survival of recently settled germlings (up to ~83% mortality). Stronger intensities of light facilitated
the growth of germlings, including the capacity for ~50% of them to outgrow detrimental sediment and survive. Temperature
(10 vs. 16°C) had no effect on early recruitment, survival, or growth. This information helps to identify likely causes and
locations of recruitment failure, and by extension, the conditions needed (either naturally or through human intervention)
to facilitate recruitment and possible habitat restoration. Ultimately, this knowledge can increase our capacity to predict
population persistence and the likely success of restoration efforts. 相似文献

Nest and territory defence are risky and potentially dangerous behaviours. If the resolution of life history trade-offs differs between individuals, the level of defence may also vary among individuals. Because melanin-based colour traits can be associated with life history strategies, differently coloured individuals may display different nest and territory defence strategies. We investigated this issue in the colour polymorphic tawny owl (Strix aluco) for which plumage varies from dark to light reddish melanic. Accordingly, we found that (1) our presence induced a greater response (flying around) from dark-coloured than light-coloured females and (2) dark reddish males suffered lower nest predation rates than light-coloured males. In experimentally enlarged broods, the probability that females reacted after we played back the hoot calls of a stranger male was higher if these females were lighter reddish; the opposite pattern was found in experimentally reduced broods with dark parents being more reactive than light parents. Finally, darker females alarmed more frequently when paired with a light than with a dark male, suggesting that partners adjust their behaviour to each other. We also tested whether colouration is used as a signal by conspecifics to adjust the level of their defensive behaviour. Accordingly, breeding females responded more vigorously to a dark than a light reddish stuffed tawny owl placed beside their nest. We conclude that melanin-based colouration is a signal of alternative nest and territory defence behaviour that depends on ecological factors. 相似文献

Close to 50 species of marine Calanoid copepods have been reported to produce diapause eggs (Engel and Hirche in J Plankton
Res 26:1083–1093, 2004); eggs that are viable but require a refractory phase before they hatch, sometimes after months. Diapause eggs are often
described as morphologically different with respect to egg membrane ultrastructure and having a thicker egg shell with surface
ornamentation as opposed to the smooth shell found in subitaneous eggs that hatch within days (Belmonte in J Mar Syst 15:35–39,
1998; Chen and Marcus in Mar Biol 127:587–597, 1997; Castro-Longoria in Crustaceana 74:225–236, 2001). Egg production rates, egg surface ornamentation, and hatching success were monitored in large aquaculture fish enclosures
during winter with close to zero water temperatures (N57°). Surprisingly, all female copepods (Acartia spp.—presumably A. tonsa, and Centropages hamatus) produced eggs all through the winter with no obvious pattern with respect to light, temperature and food availability, and
no diapause eggs were observed. However, individual females produced several categories of eggs with or without surface spines
even within the same egg batch as evidenced by scanning electron microscopy (SEM). Four egg categories were distinguishable:
‘no spines’, smooth eggs; ‘short spines’, 5–15 μm long; ‘truncated spines’, with the spine tips cut-off <10 μm long; and ‘long
spines’, up to 30 μm long. All egg categories remained unchanged with respect to surface structures from when we took them
out of the incubation bottles until they hatched. In general, the frequency of ‘no spines’ was 10–40%, and most eggs were
ornamented with ‘short-’ or ‘long spines’. Further, a given egg can be ornamented with all types of surface spines simultaneously,
which might even be a fifth egg category. The different egg categories were all able to hatch within days when exposed to
normoxic conditions suggesting that they were subitaneous. 相似文献

Leaders of the PAGES Focus 5 programme ‘Past Ecosystem Processes and Human–Environment Interactions’ identify key issues for
research on human–environment interactions for wider discussion. These include the need for long-term perspectives, the opportunities
for maximising palaeoenvironmental research, the need for integration and regionalisation and the challenge of developing
dynamic simulation models. A new organisational matrix for regional studies is outlined, based on a series of zonal/azonal
regions and on the degree of human impact. Future priorities for palaeoenvironmental research include new studies in degraded
human-dominated landscapes, highly-valued ecosystems and sites relevant to other IGBP Core Projects. Simulation of future
human–environment interactions using modelling approaches that have been tested against long records lags behind global climate
modelling, but cellular approaches for biogeophysical and multi-agent systems show promise. 相似文献
