Heavy Metal Contamination refers to the accumulation of metallic elements with high atomic weights and densities in environmental matrices, posing significant ecological and human health risks. These contaminants originate from both natural processes and anthropogenic activities, persisting in soil, water, and air due to their non-biodegradable nature. Their toxicity varies depending on chemical speciation, concentration, and exposure pathways, necessitating rigorous monitoring and remediation strategies.
"Hedonic adaptation," also known as the "hedonic treadmill," is a concept primarily discussed in psychology and behavioral economics, referring to people's tendency to return to a stable level of happiness despite major positive or negative events or life changes. However, when considering hedonic adaptation in the environmental context, it can relate to how individuals or societies adjust their expectations and satisfaction levels in response to changes in their environment, including improvements or degradations in environmental quality.
