"Environmental toxicology is a multidisciplinary field of science concerned with the study of the harmful effects of various chemical, biological and physical agents on living organisms."
The study of chemicals in the environment and their effects on living organisms.
Sample collection: The process of collecting environmental samples and identifying the appropriate methods to ensure accurate representation.
Analytical techniques: Techniques used to analyze environmental samples, such as chromatography, mass spectrometry, and spectrophotometry.
Quality assurance: A set of procedures to ensure accuracy, precision, and reliability of analytical data.
Instrumentation: The operation, maintenance, and troubleshooting of analytical instruments such as gas chromatography, liquid chromatography, and high-performance liquid chromatography.
Data interpretation: Techniques to analyze data and interpret analytical results.
Environmental monitoring: The process of collecting and analyzing environmental samples to monitor environmental conditions regularly.
Regulatory compliance: The regulations and guidelines that govern environmental testing and monitoring.
Sampling strategies: The plan and execution of sampling programs to obtain comprehensive environmental data.
Environmental standards: The criteria and limits for chemical and microbiological contamination in environmental samples.
Quality control: Ensuring data quality with laboratory quality control methods, data validation, and data reporting.
Calibration and standards: The preparation and maintenance of calibration standards for analytical instrumentation.
Method development: Developing methods and procedures to analyze specific environmental contaminants.
Risk assessment: Evaluating risks posed by environmental contaminants based on the examination of exposure pathways and toxicity information.
Data management: The organization, storage, and retrieval of environmental data.
Water quality analysis: This type of analysis determines the chemical, biological, and physical properties of water samples. It includes tests for pH, dissolved oxygen, nitrates, phosphates, and other pollutants.
Air quality analysis: This type of analysis examines the pollutants present in the air. It includes tests for particulates, ozone, carbon monoxide, sulfur dioxide, and other harmful gases that can affect human health and the environment.
Soil analysis: This type of analysis examines the properties of soil samples. It includes tests for pH, nutrient content, contaminants, and fertility. This analysis is essential for ensuring the health of plants, animals, and humans that are dependent on the soil.
Waste analysis: This type of analysis examines the composition of waste materials, including hazardous and non-hazardous waste. It includes tests for heavy metals, organic compounds, and other contaminants.
Biological analysis: This type of analysis examines the impact of pollutants on living organisms, including fish, plants, and other animals. It includes tests for toxicity, bioaccumulation, and biomagnification.
Soil and water quality modeling: This type of analysis uses mathematical models to predict the impact of pollutants on soil and water quality. It can be used to determine the sources and movement of pollutants, as well as the effect of different pollutants on the environment.
Environmental monitoring: This type of analysis involves the ongoing measurement of environmental parameters over time. It includes tests for air, water, and soil quality, as well as biological monitoring.
Ecological risk assessments: This type of analysis evaluates the potential risk of pollutants to ecosystems and their inhabitants. It includes tests for exposure, toxicity, and ecological effects.
Contaminant fate and transport modeling: This type of analysis uses mathematical models to predict the fate and transport of pollutants in the environment. It can be used to determine the impact of different pollutants on the environment and to evaluate the effectiveness of pollution control measures.
Remote sensing and geographic information system (GIS) analysis: This type of analysis uses satellite imagery and GIS to monitor environmental parameters over large areas. It includes tests for land cover change, vegetation health, and water quality.
"Ecotoxicology is a subdiscipline of environmental toxicology concerned with studying the harmful effects of toxicants at the population and ecosystem levels."
"Rachel Carson is considered the mother of environmental toxicology."
"Carson made it a distinct field within toxicology in 1962 with the publication of her book Silent Spring."
"Silent Spring covered the effects of uncontrolled pesticide use."
"Carson's book was based extensively on a series of reports by Lucille Farrier Stickel on the ecological effects of the pesticide DDT."
"Organisms can be exposed to various kinds of toxicants at any life cycle stage."
"Some life cycle stages are more sensitive than others."
"Toxicity can also vary with the organism's placement within its food web."
"Bioaccumulation occurs when an organism stores toxicants in fatty tissues."
"Bioaccumulation may eventually establish a trophic cascade and the biomagnification of specific toxicants."
"Biodegradation releases carbon dioxide and water as by-products into the environment."
"Harmful effects of such chemical and biological agents can affect an organism and its community by reducing its species diversity and abundance."
"Such changes in population dynamics affect the ecosystem by reducing its productivity and stability."
"Legislation implemented since the early 1970s had intended to minimize harmful effects of environmental toxicants upon all species."
"McCarty (2013) has warned that 'longstanding limitations in the implementation of the simple conceptual model that is the basis of current aquatic toxicity testing protocols' may lead to an impending environmental toxicology 'dark age'."
"Longstanding limitations in the implementation of current aquatic toxicity testing protocols may lead to an impending environmental toxicology 'dark age'."
