Question

What term is used to describe using plants to clean up contaminated soil? A) recycling B) composting C) phytoremediation D) sanitary landfill

Short answer

The term is C) phytoremediation.

Step-by-step solution

Understand the Definition

First, it's important to know the definitions of each term given. - Recycling refers to the process of converting waste materials into new materials and objects. - Composting is the process of decomposing organic matter into compost. - Phytoremediation uses plants to remove, transfer, stabilize, or destroy contaminants in soil and groundwater. - A sanitary landfill is a site for the disposal of waste materials by burial.

Identify the Correct Term

Based on the definitions, the term describing the use of plants to clean up contaminated soil aligns with phytoremediation.

Verify the Answer

Check the definition of phytoremediation to ensure it corresponds with using plants to remediate contaminated soils. Phytoremediation is indeed described as the use of particular plants, which are tolerant to pollutants, to absorb or break down these contaminants, thus cleaning the soil.

Key concepts

Contaminated Soil

Contaminated soil refers to soil that contains harmful substances or pollutants that can cause risks to the environment or human health. These contaminants can arise from various sources, such as industrial activities, agricultural pesticides, or accidental spills. Common pollutants include heavy metals, petroleum hydrocarbons, and organic solvents.

The presence of these toxic compounds can severely disrupt the natural soil ecosystem, affecting plant growth and potentially entering the food chain, where they can impact wildlife and human health. Significant efforts are required to address and manage contaminated soil to prevent further damage.

Environmental Science

Environmental science is the study of the interactions between the physical, chemical, and biological components of the environment. This interdisciplinary field aims to understand the complex relationships that determine the health and sustainability of our surroundings.

Environmental science helps us comprehend how human actions, such as pollution and deforestation, affect ecosystems and what measures we can take to mitigate these impacts. By doing so, it provides tools and knowledge to protect our natural resources and promote a healthier planet.

Soil Remediation

Soil remediation is the process of cleaning up contaminated soils. It involves different methods aimed at removing, neutralizing, or reducing pollutants present in the soil. Among various techniques, phytoremediation is an innovative and eco-friendly method.

Phytoremediation uses plants known for their ability to absorb, degrade, or stabilize contaminants. These plants draw up pollutants through their roots, effectively cleaning the soil over time. The method is cost-effective, aesthetically pleasing, and sustainable. It not only restores soil health but also maintains the biodiversity and structure of the soil.
