Street Science Community Knowledge and Environmental Health Justice

Abstract Street Science engages several issues that remain largely unaddressed in the environmental-policy and public-health literatures. First, increasing evidence suggests that local knowledge has contributed positively to the formulation of more sustainable resource-management practices and development decisions…Second, a growing body of literature suggests that inequalities in environmental health, morbidity, and mortality result from a combination [...]

Sensor Integration in a Wireless Sensor Network System for Environmental Monitoring System

Abstract This paper presents the implementation of the event-driven Wireless Sensor Network (WSN), which is used for environmental monitoring using soil moisture sensors. The problem faced is that the current Wireless Soil Sensor Networks are not reactive to the weather conditions around it. Which means it takes reading samples at constant rate throughout its operation. [...]

Architecture of wireless sensor networks for environmental monitoring

Abstract There are various kinds of environmental sensor networks (ESNs) implementations for monitoring environment. These facilitate the study of environment pollution and fundamental processes of meteorology. They have evolved from passive logging systems that require manual downloading, into intelligent sensor networks that comprise a network of automatic sensor nodes and communications systems which actively communicate [...]

Fuzzy Synthetic Evaluation of Water Quality of Hei River System

Abstract Identification of water quality conditions in a river system based on limited observations is an essential task for meeting the goals of environmental management. Various classification methods have been used for water quality estimation. However, a discrepancy frequently arises from the lack of a clear distinction between each water utilization mode, the uncertainty in [...]

Ecology, Engineering, and Economics

Abstract There appears to be increasing evidence that contemporary social and environmental problems and energy shortage are symptomatic of prebreakdown stresses inherent in the technical and socioeconomic organization of our system of production and consumption processes as it evolved under the “explosive” force of the industrial revolution. In an effort to understand these stresses and [...]

Ecology, Aquaculture and Space Colonies

Abstract Recent research results show that very small autotrophic/heterotrophic assemblages open to energy but totally isolated from exchanges of matter with external systems persist for years and probably indefinitely. General and specific ecological thermodynamic hypothesis for the behavior of such systems have been proposed and are being tested. Meanwhile, the National Aeronautics and Space Administration [...]

Application of Modeling for Optimal Localization of Environmental Monitoring Sensors

Abstract The control of environmental phenomena is based on the existence of quantifiable and measurable parameters representative of the phenomena themselves. In the case of studies concerning contaminated aquifers, after an initial step of characterization it is necessary to implement groundwater hydrogeochemical monitoring phases. In the field of groundwater pollution long-term monitoring realized by means [...]

A Concept in Adaptive Ecosystem Management – An engineering perspective

Abstract Uncertainty how ecosystems will behave and look like in the future has been increasing. Several concepts, such as sustainable, adaptive, or risk-based management, were proposed to cope with uncertain, incomplete knowledge, and with changing environmental conditions. However, there is a lack of agreement what those concepts mean and how they differ from traditional forest [...]

Immunoanalytical techniques for analyzing pesticides in the environment

Abstract Affinity-based immunosensing techniques for pesticide analysis have attracted intense interest and have found many applications in environmental monitoring. This article reflects recent advances in immunochemical techniques for environmental analysis and monitoring of pesticides. We highlight development of bioreceptors (e.g., antibodies) against low-molecular-weight organic pollutants, and the use of different transduction elements for detecting physico-chemical, [...]

Recent advances in biosensor techniques for environmental monitoring

Abstract Biosensors for environmental applications continue to show advances and improvements in areas such as sensitivity, selectivity and simplicity. In addition to detecting and measuring specific compounds or compound classes such as pesticides, hazardous industrial chemicals, toxic metals, and pathogenic bacteria, biosensors and bioanalytical assays have been designed to measure biological effects such as cytotoxicity, [...]

Prospects for combining chemical and biological methods for integrated environmental assessment

Abstract …Besides deploying a chemicals-driven strategy for the ecological risk assessment of the pollutants, it is necessary to apply and to explore biological strategies. Consequently, bioassays, biosensors and effect-directed analysis (EDA) to identify pollutants responsible of particular effects have become increasingly important. We give a broad overview of how to assess biological monitoring of ecosystems [...]

Recent advances in recognition elements of food and environmental biosensors: A review

Abstract A sensitive monitoring of contaminants in food and environment, such as chemical compounds, toxins and pathogens, is essential to assess and avoid risks for both, human and environmental health. To accomplish this, there is a high need for sensitive, robust and cost-effective biosensors that make real time and in situ monitoring possible. Due to [...]

Bioluminescent Escherichia coli Strains for the Quantitative Detection of Phosphate and Ammonia in Coastal and Suburban Watersheds

Abstract …Analytic chemistry kits are used to measure phosphate and ammonia levels in water samples with algal blooms, but their sensitivity is limited due to specificity for inorganic forms of these moieties. An Escherichia coli bioluminescent reporter system measured the bioavailability of inorganic nutrients through fusion of E. coli promoters ( phoA or glnAp2) to [...]

Biosensors for Environmental Monitoring at Global Scale and the EU Level

Abstract Biosensor technology is based on a specific biological recognition element in combination with a transducer for signal processing. Since their inception, biosensors have been expected to play a significant analytical role in environmental monitoring…biomonitoring is an essential tool for rapid and cost-effective environmental monitoring. For this reason, biosensor technology has been considered as a [...]
