Question

14 explain why you should not tear down asbestos and simply throw it away if you find it in your home.

15 list three types of tests you could do at your house to protect against chemical hazards.

outdoor chemical hazards
16 explain why citizens of one town might need to be concerned with the chemical hazards in the air of a town many miles away.

17 describe how chemical hazards can get into soil and some of the ways that they can cause harm to humans.

Explanation:

For question 14: Asbestos fibers are toxic when inhaled. Tearing it down releases these fibers into the air, which can be inhaled, leading to serious health issues like lung cancer, asbestosis, or mesothelioma. Proper handling by professionals is needed to contain the fibers.

For question 15: 1. Lead paint test: To check for lead in old paint, as lead is a toxic chemical. 2. Radon test: Radon is a radioactive gas that can seep into homes, and test kits can detect its levels. 3. Water quality test (for chemicals like pesticides, heavy metals): To check if drinking water or household water has harmful chemicals.

For question 16: Chemical hazards (like pollutants, pollutants from industrial emissions) can be carried by wind over long distances. Air currents can transport airborne chemicals (e.g., sulfur dioxide, particulate matter, or volatile organic compounds) from one town to another, so citizens in a distant town may be exposed to these hazards through the air.

For question 17: Chemical hazards enter soil via: 1. Industrial waste disposal (illegal dumping of chemicals). 2. Agricultural runoff (pesticides, fertilizers, or animal waste with chemicals). 3. Leaching from landfills. 4. Atmospheric deposition (chemicals from air settling into soil). Harm to humans: 1. Ingestion: Through contaminated food (crops grown in polluted soil) or water (groundwater contaminated by soil chemicals). 2. Inhalation: Dust from polluted soil can be inhaled, carrying chemicals. 3. Dermal contact: Touching contaminated soil can let chemicals enter through skin, causing irritation or absorption of toxins.

Answer:

Question 14: Asbestos fibers are toxic when inhaled; tearing it down releases fibers, causing health issues (e.g., cancer). Professional handling is required.
Question 15: Lead paint test, radon test, water quality test (for chemicals).
Question 16: Wind transports airborne chemical hazards between towns, so distant citizens face exposure.
Question 17: Chemicals enter soil via industrial waste, agriculture, landfills, or air; harm humans via ingestion, inhalation, or dermal contact.
