In perception research, the memory color effect is cited as evidence for the opponent color theory, which states that four basic colors can be paired with its opponent color: red—green, blue—yellow. This explains why participants adjust the ripe banana color to a blueish tone to make its memory color yellow as gray. [10]
Manganese contamination has been linked to neurological damage in children exposed to concentrations higher than 0.1 mg/L. [4] Exposure to manganese-contaminated water during critical developmental periods can hinder cognitive development, with studies suggesting significant long-term impacts on memory, attention, and overall learning ability.
A recent study by the University of Southern California revealed that exposure to air pollution can harm children's learning and memory, the LA Post reports.. Ammonium nitrate, a specific ...
A recent, highly publicized example of water pollution's disproportionate effect on racial minorities is the Flint water crisis. In 2014, Flint, Michigan, a city with a 57% Black population, switched its drinking water to the Flint River, which led to complaints about the water's taste and color. [48]
A practical definition of water pollution is: "Water pollution is the addition of substances or energy forms that directly or indirectly alter the nature of the water body in such a manner that negatively affects its legitimate uses." [1]: 6 Water is typically referred to as polluted when it is impaired by anthropogenic contaminants.
It is known that air pollution, particularly small particle pollution, can affect the heart and the circulatory system, including circulation to the brain. These effects are linked to vascular dementia (a form of dementia), which is caused by damage to the blood vessels in the brain. [65]
The color of a water sample can be reported as: Apparent color is the color of a body of water being reflected from the surface of the water, and consists of color from both dissolved and suspended components. Apparent color may also be changed by variations in sky color or the reflection of nearby vegetation.
From the spectrum of color coming from the water, the concentration of optically active components of the upper layer of the water body can be estimated via specific algorithms. [1] Water quality monitoring by remote sensing and close-range instruments has obtained considerable attention since the founding of EU Water Framework Directive.
