Fast GC In Environmental Analysis
Fast GC can be practical for many environmental analyses, and may not require a major investment in new equipment. By applying the techniques of Fast GC such as, using shorter, narrower bore columns, faster oven temperature ramp rates, hydrogen carrier gas, and by taking advantage of the variety of column chemistries available in fast dimensions, analyses times can be significantly reduced while ...

Environmental analysis of beer production
The concept of sustainable development is focused on the improvement of the quality of life, avoiding the unbalanced utilisation of natural resources. Several concepts have recently been developed to evaluate the use of resources and the environmental management from an individual to a global scope. One of them, Life Cycle Assessment, has been considered for the environmental analysis of a ...

Strategic knowledge creation: the case of Hamamatsu Photonics
Strategic management can be viewed as a mechanistic or an organic process. In the former, strategic formulation is based on environmental analysis. In the latter, managers are advised to frame strategies on the unique inimitable internal resources. While both heuristics are feasible, the ontological and epistemological foundations of strategic management can be elaborated. A knowledge-based view ...

Uncertainty in environmental analysis: theory and laboratory studies
In this paper, theoretical and practical aspects of uncertainty in environmental laboratory analysis are presented and discussed. A more detailed theory of uncertainty is described, with special emphasis on the factors which contribute to the understanding of this in order to obtain accurate environmental laboratory data analysis. A full discussion is reported relating to approaches used to ...

Environmental Analysis of BTEX Compounds in Soil, Water and Sludge by GC / PID
Because of the widespread use and history of indiscriminate disposal practices of gasoline and fuel oils, their analysis in environmental samples is in high demand. Gasoline and diesel are both complex mixtures containing up to 400 individual compounds. The BTEX group (Benzene, Toluene, Ethylbenzene, and the Xylenes) are naturally occurring constituents of gasoline and diesel (although ...

Technological prospective study in the environmental industrial sector: management and treatment of industrial wastes
This paper shows the tendencies and future forecasts related to the impact that technological changes can have in the treatment and management of industrial wastes in the Castille and Leon area during the next ten years. We present here a summary of a technological prospective study carried out from November 1999 to November 2000, whose purpose was to predict, in the medium and the long term, the ...

Transport and the environment in Swedish research and policy-making
The aim of this paper is to provide a short survey of recent developments in the area of transport and the environment in Sweden. Four specific studies are compared in terms of their intrinsic and meta-characteristics. The studies represent different approaches in terms of projections and/or scenarios. Future traffic developments and the attainment of adopted environmental goals are given special ...

Characteristics of the automotive remanufacturing enterprise with an economic and environmental evaluation of alternator products
Technology has improved the standard of living while resulting in serious global challenges with respect to the climate, air, water, land and material resources. Remanufacturing is a process that restores old products to perform like new, while saving energy, reducing consumption of natural resources and lowering environmental emissions. In this paper, we investigate characteristics of the ...

Why is alkalinity an important parameter in environmental water analysis?
Answer: Alkalinity is a measure of the acid-neutralizing or buffering capacity of a solution. The properties of water are is easily influenced by alkalinity, making it an important and widely used test. If any changes are made to a solution which could impact pH, alkalinity acts a buffer. This ability to neutralize acid (H+ ions) is what makes alkalinity so important. Hydroxides (OH-), carbonates ...

Green marketing: can it effectively contribute to green economics?
This paper attempts to examine the possible contribution of green marketing to green economics. It will study the impact of marketing itself on consumption, lifestyles, etc. and then define green marketing, following a brief examination of environmental ethics. An analysis of the components of green marketing will be provided with an assessment of how any or a combination of those can ...

Pesticide Analysis by GC / ECD / NPD & FID
Since 1963, when Rachel Carson published Silent Spring about the destructive power of synthetic chemicals, regulatory agencies in the U.S. have increasingly restricted the manufacture and use of pesticides. The goals of pesticide regulations are to eliminate the use of persistent chemicals like DDT, and to encourage the development of safe, targetspecific compounds. Because of the high ...

Recreational impacts on the environment as an impetus to updating recreational regulations in the Washington State
The Washington State Department of Natural Resources (DNR) uses the Washington Administrative Code (WAC) as the regulations by which the agency manages public lands for Washington State. Originally written in 1970, the part of the WAC that guides recreational public access was suitable for its time. However, as populations grew, new technology has developed and the public now recreates deeper ...

The environment and the economy: spatial issues and spatial perspectives
This paper presents a theoretical approach to analysis of spatial issues in relation to the economy-environment interface. This forms a framework for presentation of work undertaken within the European Science Foundations' TERM project, using meta-analysis, on these issues. First, meta-analysis is briefly examined, followed by a discussion of the economy-environment relationship in the context of ...

Integrated river basin project evaluation: a comparative study
Projects carried out in river basin areas often impose changes in spatial functions that are situated in these areas. For decades, project evaluation was carried out by measuring tangible streams of cost and benefits summarised in a cost-benefit analysis. Recently, environmental and social aspects gradually have got more attention in the public decision making process by means of, for example, ...

US EPA Method 8270 Semivolatiles on the Equity-5
US EPA Method 8270 describes the analysis of a wide variety of semivolatile compounds by GC/MS. In this application, the Equity-5 was used to analyze 74 compounds commonly targeted for analysis by environmental laboratories. The analysis also included 6 internal standards and 8 surrogates. The Equity column showed excellent peak shape and response for both basic and acidic compounds, including ...
