Fluoride in high doses is extremely problematic, making it a concerning pollutant. It is extremely prevalent in products used in dental health. Because these are products that are generally washed away, fluoride is of special concern as a water pollutant.

Mitigation is defined as actions taken to prevent or reduce the occurrence of natural disasters and damage to an environment. Restoration is the renewal of an environment or ecosystem after it has been almost or completely destroyed. Preservation is a collection of efforts aimed at sustaining a vulnerable or unstable ecosystem. Remediation is often the clean up or removal of contaminants from an environment.

Nitrates, a form of nitrogen, are a severe problem in drinking water that has been contaminated with fertilizers. Sewage and fertilizer often go hand in hand from agricultural areas. Arsenic and chlorine are concerning pollutants, but generally not present due to fertilizer use.

Only 5% of carbon monoxide in cities does not originate from car exhaust. Though industrial facilities are a major concern as a source of pollution, regarding carbon monoxide specifically, automobiles have a much higher impact.

Why is acid rain so harmful to marine species?
Why is acid rain so harmful to marine species?
Tap to reveal answer
"Acid shock" typically occurs during the spring time, when snow (which has retained and accumulated pollutants) begins to melt and runoff into lakes and rivers. Another detrimental effect of acid shock occurs during the spawning/developing stages of aquatic animals. For example, some salamanders and frogs prefer to lay eggs in "vernal pools", or temporary puddles of water only present in the spring. Acid shock can cause these pools to become too acidic; the eggs cannot properly develop, and they die off.

Which definition best describes the process of eutrophication?
Which definition best describes the process of eutrophication?
Tap to reveal answer
The algal blooms that result from agricultural runoff do not consume oxygen when they are living. The resulting die-off from overcrowding and lack of sunlight availability and decomposition process is what consumes oxygen in the ecosystem, causing fish to suffocate.
It is also important to recognize that hypoxia is the result of insufficient oxygen in the ecosystem, while hyperoxia is when there is too much oxygen. (Consider the meanings of the prefixes "hypo-" and "hyper-".)

Rachel Carson's Silent Spring focused primarily on the widespread application of pesticides, the lack of government regulation of said pesticides (especially DDT), and their negative impacts on bird populations (i.e. songbirds that were at risk and would result in a spring lacking their songs). The book challenged industry claims that downplayed toxicity of their products and triggered a grassroots environmental movement that helped create the U.S. Environmental Protection Agency.

It's known that pollution can have negative impacts on human health, economics, and ecological communities. Which of the following is not an effect of pollution?
Tap to reveal answer
The correct response is biodiversity conservation . Pollution alters ecological communities by adding harmful chemicals, substances, and abiotic factors into the environment. This has a negative effect on biodiversity - not a positive effect. Thus, we would not except for species to be conserved in a region with pollution. We know that pollution can lead to acid rain, contaminated water, and ozone depletion so those answer choices are incorrect.

Fertilizer runoff can cause eutrophication, where nutrient-enriched freshwater mixes with saltwater and causes huge algal bloom, such as red tide. These can be toxic to both ocean organisms and to humans.

NRCS (National Resource Conservation Service) and EPA (Environmental Protection Agency) are federal agencies, not pieces of legislation. NEPA (National Environmental Policy Act) requires environmental assesments for proposed federal projects and RCRA (Resource Conservation and Recovery Act) classifies waste as solid or hazardous and sets regulations for storage and treatment of said waste. CERCLA (Comprehensive Environmental Response Compensation and Liability Act) establishes a superfund for heavily polluted areas and holds responsible firms financially accountable.

CERCLA identifies a Potentially Responsible Party as an individual or firm that currently owns the site, owned the site at the time contamination occurred, arranged to have waste stored/disposed at the site, or transported the waste and contributed to arranging disposal at the contaminated site. Individuals who purchase land where pollutants are currently being released can be held accountable, even if they did not contribute to the pollution.
The employee of a polluting firm who did not directly arrange for or assist in the handling and disposal of waste cannot be held financially accountable for the resulting cleanup.
