The evolution of children's ideas on pollution in the framework of experiential and socioconstructivist activities
In a polluted village, researchers identified the initial conceptions of students on pollution and on the relationship between pollution and health. They then provided the students with a conceptual change process based on experiential and socioconstructivist activities: fieldtrips, analysis of environmental stressors, experimentation of a health improvement plan, and environmental action. ...

Research on prediction of tourists' quantity in Jiuzhaigou Valley scenic based on ABR@G integration model
As the uncertain changes of tourists' quantity have challenged scenic management, which affects the environmental pollution, many researches confirm that forecasting, which is the foundation of the tourists' management can provide guarantee of effective environment protection. Because the changes of tourists' quantity with complex characteristics of the linear and non–linear are mutually ...

Air pollution and health: Do popular portrayals reflect the scientific evidence?
Environmentalists, regulators, health scientists, and journalists are the main purveyors of information on air pollution health risks. Unfortunately, these groups create the appearance that harm from air pollution is much greater and more certain than suggested by the underlying evidence. The incentives in air pollution health research encourage risk exaggeration, because information purveyors ...

Eco-innovations and industrial organisation: a review of complementary explanations of unsustainable economic paths
Technological "lock-in" is a form of macrolevel "network" externality and thus a form of market failure. What it can imply is that firms in an industry maintain (and replace) capital stock which is technologically sub-optimal because of "quasi-irreversibilities": it is only privately optimal for one firm to shift its technological base if other firms in the industry follow suit. This form of ...

Coriolis bio air sampler spotted on French TV!
The Bertin Instruments’ biological air sampler, Coriolis®, was shown in the beginning of the Thalassa TV show to control bio-contamination quality in the air. Thalassa is an historical French TV show entirely focused on the sea, geography, ecology, environment… For three months, aboard a Russian icebreaker transformed into a floating laboratory, oceanographers, glaciologists ...

Best practices for air sampling in veterinary environment with the Coriolis®μ
It is extremely important to monitor exposure to bio-contamination not only in clean room environments based in research laboratories and hospitals, but also in veterinary-based facilities such as CAFOs, farms and life-stock areas. Reducing the risk of exposure to airborne bio-contaminants is crucial for the human and animal well-being in those environments. Over the past 20 years, an increasing ...

Sorption of DOM and hydrophobic organic compounds onto sewage-based activated carbon
Treatment of stormwater via sorption has the potential to remove both colloidal and dissolved pollutants. Previous research shows that activated carbon produced from sewage sludge is very efficient in sorbing hydrophobic organic compounds (HOCs), frequently detected in stormwater. The aim of this research was to determine whether the presence of dissolved organic matter (DOM) has a negative ...

Native, acidic pre-treated and composite clay efficiency for the adsorption of dicationic dye in aqueous medium
Environmental applications of composites have attracted the interests of researchers due to their excellent adsorption efficiency for pollutants. Native, HCl pre-treated clay and MnFe2O4/clay composite were investigated as an adsorbent for removal of methyl green from aqueous solution. The adsorption behaviors of dye onto native, HCl pre-treated and composite clays were studied as a function ...

Coriolis air samplers are currently used for avian flu research
Avian influenza refers to the disease caused by infection with avian (bird) influenza (flu) Type A viruses. These viruses occur naturally among wild and domestic birds worldwide and can also infect other animal species. As infection by avian influenza has environmental, health and economic impacts, the CDC (Center for Disease Control) and the World Health Organization (WHO) constantly monitor ...

Environmental management: An agenda for action
A business agenda for sustainable development is described, where the main thrust is to be the manufacture of durable and recyclable goods by processes which minimize the production of waste and polluting emissions. This is to be achieved through education, research and innovation with a more open dialogue between producers and society.Keywords: recycling technology, sustainable development, ...

Discover the richness of microorganism in Polar Regions
Global warming is one of the main challenge worldwide for the coming years. Scientists have already warned the international community regarding the increasingly rapid melt of the ice caps and its dramatic consequences around the globe. Polar regions are the most isolated place on Earth, uninhabited due to their harsh climate conditions. The study of this regions’ unknown bioaerosols ...

Understanding aqueous trace metal characteristics from industrial sources in China
Trace metals are a group of toxic pollutants that can cause serious damage to ecosystems and humans. To determine the distribution characteristics of aqueous trace metal contamination and identify critical pollution sources, it is necessary to develop a detailed estimation of trace metal emissions. By considering emission-related factors in each industrial sector, we estimate that the ...

Agricultural runoff contaminant discharge in Dianchi Valley agricultural district, China
release of pollutants in Agricultural Runoff (AR) from a plastic canopy (PC) region in eastern Dianchi Catchment of China was investigated. The daily variation coefficients of water quantity in 2002 and 2003 were 15.9 and 7.6 respectively. From May 2002 to September 2003, local farmland had discharge of 2.9?3.2 l m2 d1. Pollutant loads from research area to Dianchi Lake from October to April were ...

TOC and TN Measurements of Seawater
For pollution control of the ocean and in the research of the ocean environment, the measurement of total organic carbon (TOC) is regarded as an important index of organic contaminants contained in seawater. At the same time, the measurement of total nitrogen (TN), which is known to cause eutrophication, is also attracting attention for environmental pollution control and in ecological ...

Simulation of flow in an idealised city using various CFD codes
In the framework of the COST 732 action, several teams run models to verify the proposed Best Practice Guideline (Franke et al., 2007). The data set concerns the Mock Urban Setting Test (MUST) experiment, where wind field and dispersion measurements were conducted for an array of obstacles as a full-scale experiment, as well as in a wind tunnel. The pollutant transport research group at the ...

Generation of mt:egfp transgenic zebrafish biosensor for the detection of aquatic zinc and cadmium
Zebrafish embryo toxicity test has become a popular method for detecting the environmental pollutions. But our research showed that zebrafish embryos exhibited no visible paramorphia, malformation or mortality when exposed to heavy metals in a range above the environmental standard limits, indicating that zebrafish embryo an imprecise model in monitoring environmental heavy metals ...

Inhibitory effect of thiourea on biological nitrification process and its eliminating method
Thiourea is a typical nitrification inhibitor that shows a strong inhibitory effect against the biological nitrification process. The 50% inhibitory concentration (IC50) of thiourea on nitrification was determined to be 0.088 mg g VSS−1, and nitrifiers recovered from the thiourea inhibition after it was completely degraded. The thiourea-degrading ability of the sludge system was improved to ...
