Environmental Monitoring and Assessment
|November 19, 2013
Summary
Environmental risk assessment needs new methods. Symptom-oriented biological effect-test systems, or bioprobes, offer sensitive detection of environmental changes and a broad response to chemicals.
Area of Science:
- Environmental Science
- Toxicology
- Biotechnology
Background:
- Pre-marketing chemical assessments have errors and uncertainties.
- Current methods are inadequate for detecting unexpected environmental trends due to complex anthropogenic impacts.
- There is a need for sensitive biological effect-test systems to monitor environmental quality.
Purpose of the Study:
- To introduce the concept and requirements for symptom-oriented biological effect-test systems, termed 'bioprobes'.
- To propose bioprobes as environmental quality measuring devices capable of detecting unknown environmental changes.
- To highlight the advantages of bioprobes over traditional chemical testing biotests.
Main Methods:
- Bioprobes are designed to respond to a broad spectrum of anthropogenic chemicals.
- These systems consist of cultivated organisms, cells, organelles, or biomolecules coupled with recording units.
- Bioprobes are exposed to specific environmental segments for defined periods to observe biological responses.
Main Results:
- Bioprobes are proposed as sensitive indicators of environmental changes of unknown origin.
- They offer a method for detecting unexpected trends missed by traditional risk assessments.
- Changes in defined biological states or process rates ('observation elements') are registered post-exposure.
Conclusions:
- Bioprobes represent a novel approach to environmental monitoring and risk assessment.
- They provide a sensitive, broad-spectrum tool for evaluating environmental quality.
- This method addresses the limitations of current practices in detecting complex environmental impacts.

01:23Toxicity Testing in Animals
222
Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...

Microbial biosensors are analytical devices that utilize living microbes to detect specific substances through measurable signals. These devices consist of two main components: biosensing organisms and signal-transducing elements. Biosensing organisms, such as Escherichia coli or Saccharomyces cerevisiae, are typically housed in multiwell plates connected to transducers, enabling rapid, real-time detection of target analytes.Signal Generation MechanismWhen a target analyte—such as...

Automated diagnostic analyzers have transformed clinical microbiology by providing rapid and reliable methods for pathogen identification and antibiotic susceptibility testing. Among these systems, the Vitek 2 is widely used because it automates the traditionally labor-intensive processes of microbial identification (ID) and antibiotic susceptibility testing (AST), delivering standardized and timely results that are essential for effective patient care.Microbial Identification with ID CardsThe...

01:26Toxic Reactions: Overview
4.3K
When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
