POLLUTION KIT: Thermal Chemical
Uses yeast to represent oxygen consuming micro-organisms on animals and how the effect of temperature on biological oxygen demand and dissolved oxygen in water is explored.
Relate this to the metabolism of an organism.
Also investigates chemical pollution by poisons directly (lead ions) and indirectly (phosphate ions) that disrupt what lives in water by favoring the growth of a single type of organism.on can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants have an anthropogenic source – that is, a source created by human activities.
Pollution is often classed as point source or nonpoint source pollution. In 2015, pollution killed nine million people worldwide (one in six deaths). This remained unchanged in 2019, with little real progress against pollution being identifiable. Air pollution accounted for ¾ of these earlier deaths. Major forms of pollution include air pollution, light pollution, litter, noise pollution, plastic pollution, soil contamination, radioactive contamination, thermal pollution, visual pollution, and water pollution…”)
