Algal Bloom
An immediate increase in the amount of algae and other producers that results from a large input of a
limiting nutrient.
Biochemical Oxygen Demand (BOD)
Amount of oxygen required by aquatic bacteria to decompose given load of organic waste; a measure of
water pollution.
Biomagnification
the trophic level, the higher the concentration The increase in chemical concentration in animal tissues
as the chemical moves up the food chain. the higher
example of biomagnification
eggshell thinning and developmental deformities in top carnivores of the higher trophic levels
effects of biomagnification on humans
include issues with the reproductive, nervous and circulatory systems
,substances that bioaccumulate and have significant environmental impacts
DDT, mercury, and PCBs (polychlorinated biphenyls)
Polychlorinated biphenyls (PCBs)
A group of industrial compounds used to manufacture plastics and insulate electrical transformers, and
responsible for many environmental problems.
Bioaccumulation
the selective absorption and concentration of elements or compounds by cells in a living organism, most

A process that allows the organic material in solid waste (such as food scraps, paper, yard waste) to be
decomposed and reintroduced into the soil, often as fertilizer.
drawbacks of composting
odor and rodents, can attract predatory animals such as bears
how can e-waste be reduced?
by recycling and reusing
negative impacts of e-waste
may contain hazardous chemicals, including heavy metals such as lead and mercury, which can leach
from landfills into groundwater if they are not disposed of properly
landfill mitigation strategies
range from burning waste for energy to restoring habitat on former landfills for use as parks
negative impacts on coral reefs
