Environmental Science
Across
- 2. emissions that are released into the environment from many points, not just one
- 3. gradual accumulation of substances, such as pesticides or other chemicals, in an organism.
- 5. pollution from man made activities
- 7. when you get a greater effect by combining two or more organisms or components together than you would get by adding the effects of each.
- 10. the quality of being toxic or poisonous.
- 12. a substance capable of causing cancer in living tissue
- 13. a process or place that removes, stores or absorbs the pollutant
- 14. the dose of a substance that is sufficient to kill 50% percent of the specified test animal within a set period of time
- 16. the adverse health effects of repeated doses or exposure to the material over a relatively prolonged period
- 18. organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes.
- 20. how much of a pollution a person is exposed to in a given amount of time
Down
- 1. emissions that are released from a single identifiable point, specified site or location
- 4. emissions of gases or vapors from pressurised equipment due to leaks and other unintended or irregular releases of gases, mostly from industrial activities
- 6. any air pollution emitted by motor vehicles, airplanes, locomotives, and other engines and equipment that can be moved from one location to another
- 8. adverse effects of a substance that result either from a single exposure or from multiple exposures in a short period of time
- 9. any concentration of a toxin, such as pesticides, in the tissues of tolerant organisms at successively higher levels in a food chain.
- 11. the point at which there is an abrupt change in an ecosystem quality, property or phenomenon, or where small changes in an environmental driver produce large responses in the ecosystem
- 15. the amount of chemical absorbed per unit of body weight
- 17. the dose of a substance that is sufficient to kill a percentage of the specified test animal within a set period of time
- 19. a colourless pungent toxic gas formed by burning sulphur in air
