Question

Oil spills are a major environmental concern, so tools have been developed to help respond to oil spills effectively. Responders use tools such as Environmental Sensitivity Index (ESI) maps to show which coastal areas are at greatest risk from an oil spill and the Chemical Aquatic Fate and Effects (CAFE) database to provide information about what happens when particular chemicals get into the environment. Explain how tools such as these are useful in responding to an oil spill, including how they help responders make a plan and how they reduce the environmental impact of the spill.

Answer 1

Explanation:

Environmental sensitivity index (ESI) maps are a compilation of information about coastal shoreline sensitivity, biological resources, and human resources. The information on the ESI is used in planning in order to create cleanup strategies before an accident occurs so that authorities are prepared to take action in the event of such oil spill. Prior planning reduces the harmful effects of oil spills in the environment WHILE Chemical Aquatic Fate and Effects (CAFE ) serves as a tool to help responders to determine the environmental impacts of chemical or oil spills into an aquatic environment. CAFE can be used to choose between four different spill scenarios: chemical, oil only, dispersant only, and dispersants mixed with oil.

Answer 2

• Environmental sensitivity index (ESI) maps are a compilation of information about coastal shoreline sensitivity, biological resources, and human resources. This information is used in planning to create cleanup strategies before an accident occurs so that authorities are prepared to take action in the event of such a spill. Advance planning reduces the harmful consequences of oil spills and cleanup.

• The Chemical Aquatic Fate and Effects (CAFE) database is a software program you can use to estimate the fate and effects of thousands of chemicals, oils, and dispersants. CAFE serves as a tool to help responders in their assessment of environmental impacts from chemical or oil spills into an aquatic environment.

Step-by-step explanation:

• The environmental sensitivity index maps were founded in 1970's to reduce the risk of oil spills in the water bodies by identifying the areas that can be reached by oil spills and also making decisions during a spill event
• .The ESI are helpful in the preservation of marine environment since it demands for specific clean up actions and response options considering ecological,recreational and commercial concerns and also guides responses to marine oil spills.

• The chemical aquatic fate and effects produces information that is needed incase of an oil spillage incident.
• It is divided into three aquatic fate modules;structure and physical properties that displays basic chemical information used for modelling,environmental mode;that displays detailed environmental explanations on the fate and behaviour of individual chemicals in different media and the analytical method;that displays methods used in measuring chemical levels in media and their uses.
