Pollution Contaminated Resources
Pollution Objectives:
-
Describe how air pollutants link to acid deposition and ozone depletion.
-
Provide examples of point source and non-point source water pollution.
-
List common soil contaminants and their possible impacts.
This section introduces some of the pollutants that impact the atmosphere, hydrosphere, and lithosphere.
We are starting with examples of air pollution.
Technology for monitoring air pollutants has become less expensive and more widely available. This is an inexpensive air monitor, some models can send updates and warning to a device.
Water Pollution
Water pollution comes in different forms, but all are challenging to address.
Laboratory testing is typically more accurate than home testing as smaller quantities can be measured and equipment is calibrated routinely. However, home water test kits may indicate issues that need further analysis.
Aquatic bioindicators are species that are present in either clear or contaminated bodies of water. The presence (or absence) or certain species gives us an indication of whether our ponds are contaminated by pollutants.
We frequently field this question at the coast. Is the foam and smelly stuff pollution? In the protected bays, it is usually decaying algae. In the tide pools, it is sometimes massive amounts of sperm and eggs produced by the animals that stay clinging on the rocks.
Soil Pollution
Identifying soil pollution is not always as easy as in this photo. In addition to large waste, smaller contaminants can move into the soil. Some pollutants like cadmium, chromium, and lead can be harmful to human and wildlife health at low concentrations.
Home soil tests are typically used to determine whether garden soil has enough nutrients for optimal plant growth. You can also purchase kits to test for possible contaminants, although like water testing, it would be important to verify results through a laboratory. Some future homeowners include soil testing, along with water testing, during the inspection of a property that is for sale.
Finding new perspectives of, and solutions to, environmental problems can benefit from creativity and artistic expression. These artists have used plastic beach debris to form huge eye-catching sculptures. This effectively messages the extent of pollution washing on shore.
The next section discusses the causes and impacts of climate change.
