Question

Particulate Air Pollution Investigation Purpose develop an understanding of the number and type of particulates in the air around the school or your home. Question: What location in your school or home has the most particulate pollution? Hypothesis: a prediction about which location will have the most particulate pollution and be sure to include this in the introduction of your lab report. Materials: masking tape Ziploc bags 7 index cards magnifying glass petroleum jelly Procedure i. Decide upon 6 locations in your school or home that you would like to test for particulate pollution. Record this in the data section. 2. write a hypothesis. Remember that your hypothesis should be in the form of a statement and answer the investigation question. 3. Create 7 separate particulate collectors. a. Using a quarter make a circle in the center of each index card. b. smear each index card with a thin layer of petroleum jelly. c. Write your name and location number on each card (one will be a control). d. Place each particulate collector in bag and close immediately. 4. Remove the particulate collectors from their bags, and leave them exposed to the air at 6 locations where particulate levels may differ for 24 hours Designate card #1 as a control and leave it sealed in the bag if want to hang the particulate collectors you can punch asmall hole in one end and attach a piece of 5. After 24 hours retrieve the cards and place them back in their Ziploc bags. Examine the index cards, including your control, with a magnifying glass. Count the number of particulates that fell on each one within the circle and record these numbers in the data table. 6. Examine and describe the particulates (identifying them if possible) and record this in your data table.

Answer 1

Answer

generally the place which is having fire in the home or school should be more particulate pollution so that should be kitchen.

Report about particulate pollution:

Introduction:

particulate air pollution is anything solid or liquid suspended in the air. It includes smoke, fumes, soot, and other combustion byproducts, but also natural particles such as windblown dust, sea salt, pollen, and spores. It includes primary particles coming directly out of exhaust stacks and tailpipes, but also can include secondary particles such as sulfates and nitrates which form from condensation of vaporized materials or from the byproducts of the oxidation of gases in the atmosphere. So particulate air pollution is a mixture of contaminants from a range of sources.

Criteria pollutants, regulated to achieve the attainment of the National Ambient Air Quality Standards (NAAQS), including primary standards for the protection of public health

Sources of particulate pollution

PM found indoors will include particles of outdoor origin that migrate indoors and particles that originate from indoor sources. Indoor PM can be generated through cooking, combustion activities (including burning of candles, use of fireplaces, use of unvented space heaters or kerosene heaters, cigarette smoking) and some hobbies. Indoor PM can also be of biological origin.
For more information on major indoor combustion related sources see also:

• Stoves, Heaters, Fireplaces and Chimneys
• Environmental Tobacco Smoke

Outdoor PM originates from a variety of anthropogenic sources, including diesel trucks, power plants, wood stoves, and industrial processes.

Some negative health effect of Particulate pollution:

Exposure to inhalable particles can affect both your lungs and your heart. Many studies directly link the size of particles to their potential for causing health problems. Small particles (less than 10 micrometers in diameter) can get deep into your lungs, and some may even get into your bloodstream. People with heart or lung diseases such as coronary artery disease, congestive heart failure, and asthma or chronic obstructive pulmonary disease (COPD), children and older adults may be at greater risk from PM exposure. Scientific studies have linked PM exposure to a variety of health impacts, including:

• Eye, nose and throat irritation;
• Aggravation of coronary and respiratory disease symptoms; and
• Premature death in people with heart or lung disease.
