Which population is most likely to increase their exposure to bio-accumulated toxins?

The group most likely to increase their exposure to bio-accumulated toxins is omnivores. This is due to the fact that omnivores consume a wider variety of foods, including both animal and plant products. As toxins such as heavy metals, pesticides, and other environmental contaminants often accumulate in the tissues of animals at higher levels than in plants, those who consume meat, fish, and dairy products—elements commonly included in an omnivorous diet—are at a greater risk of ingesting these harmful substances.

Bio-accumulation refers to the process by which certain toxins build up in living organisms over time, often through the food chain. Fish, for instance, especially larger species like tuna or shark, tend to have higher concentrations of mercury and other persistent organic pollutants. This risk is more apparent in omnivores due to their consumption patterns, which typically include these high-trophic-level animals.

In contrast, populations such as vegans and vegetarians, who primarily consume plant-based foods, may have lower exposure to these toxins since they do not consume animal products that are often the vessels for bio-accumulated substances. Fruitarians, who focus solely on fruit, also likely have reduced exposure compared to omnivores, as fruits
