Question

etect without special equipment.
levels, co can cause headaches, dizziness, nausea, and fatigue.
with _____________ exposure, impaired vision, _____________, lowered
brain function, and _____________ can occur.

• sources of co include leaky or unvented stoves, ____________________, and

______________________.

lead

• people can be exposed to lead through the ____, ___________________,

contaminated soil, lead - based ____________, and dust.

• lead poisoning can damage the brain, liver, kidneys, and stomach.
• it can also lead to _________________________, behavior abnormalities,

anemia, hearing loss, and even __________.

Explanation:

For the Carbon Monoxide (CO) section:

• For the first blank in the CO exposure effects: "higher" (as higher exposure to CO leads to more severe symptoms).
• The second blank: "confusion" (a common symptom of increased CO exposure, along with impaired vision and lowered brain function).
• The third blank: "unconsciousness" (severe CO exposure can cause unconsciousness).
• For CO sources: Common sources include leaky or unvented stoves, "furnaces" (unvented or faulty furnaces can emit CO), and "automobile exhaust" (cars produce CO, especially in enclosed spaces).

For the Lead section:

• Exposure routes for lead: People can be exposed through the "air" (lead particles in the air), "water" (contaminated water supplies), and "lead - based paint" (old paint with lead is a common source).
• Effects of lead poisoning: It can lead to "learning disabilities" (lead affects cognitive development, especially in children), and in severe cases, "death".

Answer:

s:

Carbon Monoxide (CO) blanks:

• with \(\boldsymbol{\text{higher}}\) exposure, impaired vision, \(\boldsymbol{\text{confusion}}\), lowered brain function, and \(\boldsymbol{\text{unconsciousness}}\) can occur.
• Sources of CO include leaky or unvented stoves, \(\boldsymbol{\text{furnaces}}\), and \(\boldsymbol{\text{automobile exhaust}}\).

Lead blanks:

• People can be exposed to lead through the \(\boldsymbol{\text{air}}\), \(\boldsymbol{\text{water}}\), contaminated soil, lead - based \(\boldsymbol{\text{paint}}\), and dust.
• It can also lead to \(\boldsymbol{\text{learning disabilities}}\), behavior abnormalities, anemia, hearing loss, and even \(\boldsymbol{\text{death}}\).
