Asbestos is highly friable, meaning that as it ages, asbestos fibers break down easily into tiny filaments and particles. This makes asbestos especially harmful when it is disturbed or exposed and becomes airborne, as often occurs during renovation or remodeling.
For what environmental issues are CFCs blamed?
Chlorofluorocarbons (CFCs) are to blame for global warming since the 1970s and not carbon dioxide, according to a researcher from the University of Waterloo in a controversial new study published in the International Journal of Modern Physics B this week.
What are the three main types of environmental issues quizlet?
Environmental issues fall into three general categories, like Resource use, Population Growth, and pollution. Anything in the environment that is used by people. Anything in the environment that is used by people. Contamination of land, water, or air.
In which phase of an environmental assessment does confirmation of the presence of hazardous substances take place?
The purpose of a Phase II Environmental Site Assessment Report is to evaluate the presence, or absence of, petroleum products or hazardous substances in the subsurface of the site.
Which written statement will be used to consider ways to minimize a project’s negative impact on the environment?
CEQA Documents Defined
A Negative Declaration (ND) is a written statement, usually prepared by the lead agency, describing the reasons that a proposed project will not have a significant effect on the environment, and does not require the preparation of an EIR.
What are two reasons CFCs are problematic for the climate?
Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth’s protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun. CFCs and HCFCs also warm the lower atmosphere of the earth, changing global climate.
Which of the following issues is the cause of the environmental impacts caused by humans?
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Why is population growth an environmental issue?
Human population growth impacts the Earth system in a variety of ways, including: Increasing the extraction of resources from the environment. … The process of removing resources, in turn, often releases pollutants and waste that reduce air and water quality, and harm the health of humans and other species.
Why is human population growth an important topic and environmental science quizlet?
Why is human population growth an important topic in environmental science? People use earth’s resources so the size of the human population is important in studying the amount of resource use and waste produced.
Is the condition of Earth’s land water or air is called pollution?
Pollution is the process of making land, water, air or other parts of the environment dirty and not safe or suitable to use. This can be done through the introduction of a contaminant into a natural environment, but the contaminant doesn’t need to be tangible.
What is a Phase 3 environmental site assessment?
Phase III assessments include additional intrusive testing and a plan to mitigate environmental issues based on the results of the previous assessments. During this phase, the size and source of the contamination will be characterized through methods such as installation of ground water monitoring wells.
Who pays for environmental assessment?
If the lender initially pays for the ESA, the cost will be passed on to the buyer as part of the closing costs. The buyer or developer can also arrange for an ESA. Smaller lenders may require the buyer to get one, or the buyer may want to know the condition of the property before the close.
What does a Phase 2 environmental report consist of?
The Phase II ESA, also referred to as a “subsurface investigation” or more commonly “site investigation,” typically consists of collecting a series of soil, soil gas, which includes sampling for vapor intrusion, and groundwater samples and sending the samples to a laboratory to determine if dry cleaning operations have …
Why is an environmental impact statement required?
The environmental impact statement (EIS) is a government document that outlines the impact of a proposed project on its surrounding environment. … Environmental impact statements are meant to inform the work and decisions of policymakers and community leaders.
What is the purpose of an environmental impact report?
As stated in the State CEQA Guidelines, an EIR is an “informational document” intended to inform public agency decision makers and the public of the significant environmental effects of a project, identify possible ways to minimize the significant effects, and describe reasonable alternatives to the project.
What triggers an environmental impact statement?
Environmental Impact Statements (EIS) Federal agencies prepare an Environmental Impact Statement (EIS) if a proposed major federal action is determined to significantly affect the quality of the human environment. The regulatory requirements for an EIS are more detailed and rigorous than the requirements for an EA.
