A survey of storm runoff fecal coliform bacteria (FCB) from working farm and ranch pastures is presented in conjunction with a survey of FCB in manure management systems (MMS). The cross-sectional survey of pasture runoff was conducted on 34 pastures on five different dairies over 2 yr under varying conditions of precipitation, slope, manure management, and use of conservation practices such as vegetative filter strips. The MMS cross-sectional survey consisted of samples collected during 1 yr on nine different dairies from six loafing barns, nine primary lagoons, 12 secondary lagoons, and six irrigation sample points. Pasture runoff samples were additionally analyzed for Cryptosporidium sp. and Giardia duodenalis, whereby detectable concentrations occurred sporadically at higher FCB concentrations resulting in poor correlations with FCB. Prevalence of both parasites was lower relative to high-use areas studied simultaneously on these same farms. Application of manure to pastures more than 2 wk in advance of storm-associated runoff was related to a > or =80% reduction in FCB concentration and load compared to applications within 2 wk before a runoff event. For every 10 m of buffer length, a 24% reduction in FCB concentration was documented. A one-half (75%), one (90%), and two (99%) log10 reduction in manure FCB concentration was observed for manure holding times in MMS of approximately 20, 66, and 133 d, respectively. These results suggest that there are several management and conservation practices for working farms that may result in reduced FCB fluxes from agricultural operations. 相似文献

A dynamic aquatic model (DynA model) was previously developed to predict the fate of a chemical in aquatic scenarios characterized by daily or periodic changes in several input parameters. DynA model is here calibrated with data obtained from the literature in specific unsteady state scenarios, such as those of rice fields. The results obtained for two herbicides (cinosulfuron and pretilachlor) in rice paddy scenarios revealed the capability of the model to accurately predict water and sediment concentrations, as shown by some statistical indicators. Modelling efficiency (EF) values of 0.86-0.99 for the water compartment and of 0.77-0.84 for sediment show the good agreement between predicted and measured concentrations. An "external validation" was performed using measured data for a different herbicide (molinate) applied in a Portuguese paddy rice scenario. A sensitivity analysis for this volatile chemical revealed the influence of some climatic parameters (e.g. temperature) to the model outcomes, such as water and sediment concentrations. This confirmed the capability of DynA model as an efficient tool for the pesticide risk assessment in dynamic scenarios. 相似文献

Located on the northeast Brazilian coast, Olinda is one of UNESCO’s World Heritage Sites, which is economically dependent
on tourism, commerce, industry, and the informal economy. Despite its environmental and socioeconomic importance, the city
of Olinda (understanding the coast as part of it) has suffered several environmental and human disturbances over the last
decades. This work describes the environmental and social status of Olinda’s beaches and makes recommendations concerning
the development of an Integrated Coastal Management Plan for this coastal zone of the Brazilian littoral. The methodology
adopted in this study is based on field campaigns (social, physical, chemical, and biological data collection), local observations,
and the collection of sea contention building project data from city hall. The results showed that along the seven studied
beaches, the main problems were related to the: (i) building of coastal protections, (ii) inefficient sewage disposal systems,
(iii) inefficient urban management, and (iv) natural events (equinoctial spring tides and precipitation/evaporation rates).
Casa Caiada beach showed the best hydrologic conditions as a consequence of its morphology and it presents facilities that
attract housing and recreation investments (by private and public sectors) valuing and improving local use conditions. The
obtained data showed that the studied beaches need an urgent action plan to minimize the environmental degradation of Olinda’s
littoral and to promote sustainable development of the local coastal environments. 相似文献

This paper explores issues that are central to ecological economics. In spite of a substantial body of research and other
literature that has appeared in recent decades on transition, and countless other efforts, no progress has been made to halt
the increase in global warming, global emissions, rampant population growth, or several hundred other critical planet sustainability
indicators including global species extinction. The opposite is true. Consumption has escalated and it is poised to double
and, with it, planetary decay has followed closely. The aim of this work is to introduce a pragmatic solution and the economics
mechanisms solidly rooted in science, in the laws of conservation of mass and energy, and in environmental and ecological
sustainability that are necessary to overcome the tremendous forces of social, political, and economic resistance to major
change. To advance towards a sustainable civilization, adopting a holistic approach with those underlying principles in all
aspects of human activity, among others economy, finance, industry, commerce, engineering, politics, architecture, and education,
is both lacking and fundamentally required. A short review of the state-of-the-art of the science on the critical status of
the planet’s resources and its life-supporting systems is presented, as well as a brief catalog of the seminal works of the
science that gave rise to its metrics and established early on the groundwork for the understanding of the degree of sustainability
of the planet. We present the argument why past and current schemes of human economics, organization, culture, and politics
cannot achieve anything else, but complete and utter failure under their own underlying precepts. A rigorous and disciplined
process on how to overcome and avoid the precipitous decline and collapse of the environmental and planetary biosystems on
which all life depends, including human life, and a new view towards the world and the universe we all have no choice but
to live in, are also offered. 相似文献

The technical feasibility of using stopper-derived cork as an effective biosorbent towards bivalent mercury at environmentally relevant concentrations and conditions was evaluated in this study. Only 25 mg/L of cork powder was able to achieve 94 % of mercury removal for an initial mercury concentration of 500 μg/L. It was found that under the conditions tested, the efficiency of mercury removal expressed as equilibrium removal percentage does not depend on the amount of cork or its particle size, but is very sensitive to initial metal concentration, with higher removal efficiencies at higher initial concentrations. Ion exchange was identified as one of the mechanisms involved in the sorption of Hg onto cork in the absence of ionic competition. Under ionic competition, stopper-derived cork showed to be extremely effective and selective for mercury in binary mixtures, while in complex matrices like seawater, moderate inhibition of the sorption process was observed, attributed to a change in mercury speciation. The loadings achieved are similar to the majority of literature values found for other biosorbents and for other metals, suggesting that cork stoppers can be recycled as an effective biosorbent for water treatment. However, the most interesting result is that equilibrium data show a very rare behaviour, with the isotherm presenting an almost square convex shape to the concentration axis, with an infinite slope for an Hg concentration in solution around 25 μg/L. 相似文献

Policy responses for local and global fire management as well as international green-gas inventories depend heavily on the
proper understanding of the annual fire extend as well as its spatial variation across any given study area. Proper statistical
models are important tools in quantifying these fire risks. We propose Bayesian methods to model jointly the probability of
ignition and fire sizes in Australia and New Zeland. The data set on which we base our model and results consists of annual
observations of several meteorological and topographical explanatory variables, together with the percentage of land burned
over a grid with resolution of 1° across Austalia and New Zealand. Our model and conclusions bring improvements on the results
reported by Russell-Smith et al. in Int J Wildland Fire, 16:361–377 (2007) based on a similar data set. 相似文献
