  "term": "Stressor",
  "field": "Environment",
  "definition": "1. Any physical, chemical, or biological entity that can induce an adverse response.\n\n2. Refers to bottom sediment material in a natural water system.\n\n3. A stressor is any physical, chemical, or biological entity that can induce an adverse response. Stressors may adversely affect specific natural resources or entire ecosystems, including plants and animals, as well as the environment with which they interact.\n\n4. Any substance or condition that adversely impacts the aquatic ecosystem.\n\n5. Any physical, chemical or biological entity that can induce an adverse effect. A change in the level of a stressor may be the proximate cause of the biological effect under investigation, or may be one event of several required to produce the effect, or may not contribute to causation. Stressor Identification focuses on stressors that can induce biological effects.\n\n6. \"Any physical, chemical, or biological entity that can induce an adverse response\" (RAF 1992, 38).\n\n7. Physical, chemical, or biological entities that can induce adverse effects on ecosystems or human health.\n\n8. Any physical, chemical, or biological entity that can induce an adverse response. Stressors may also be the lack of an essential entity, such as a habitat.\n\n9. Physical, chemical, or biological entity that can induce adverse effects on ecosystems or human health. [Report on the Environment (ROE) Glossary][EPA 2005b]\n\n10. Any physical, chemical, or biological entity that can induce an adverse response. [EPA 1998a][Thesaurus of Terms Used in Microbial Risk Assessment]\n\n11. The term \"stressor\" includes the connotation that the adverse response can be the result of a lack of something - such as a habitat - which would also be called a \"stressor.\" The term \"agent\" does not have this connotation, and is only used to denote a causative entity that actually physically exists as part of the environment. [IPCS 2001]\n\n12. Physical, chemical, or biological factor that may cause stress in the aquatic system or contribute to pollution.\n\n13. A physical, chemical, or biological entity that can induce adverse effects on ecosystems or human health.\n\n14. A physical, chemical, or biological factor that may cause stress in the aquatic system or contribute to pollution.\n\n15. Any biological, chemical, or physical entity that can cause or induce an adverse response in a human or ecological receptor.",
