SKILLS-BASED TASK BIOLOGY 5 – BORDER CONTROLS
The UK Border Agency searches lorries at
ports. If they suspect a lorry is carrying illegal
passengers, they can direct the lorry into a
detector shed. Four sensors are put on the
truck. These pick up tiny movements inside
the truck, even from someone breathing. A
carbon dioxide detector can also be inserted
into the lorry.
The leaflet needs to explain:
• How detectors are used by the UK Border Agency.
• The reasons why the detectors are used.
• The science behind using carbon dioxide detectors.
A history of carbon dioxide
Jan Baptiste van Helmont (1580-1644) found that burning charcoal produced a gas, which he called wild spirit because it was difficult to
collect. Later, Joseph Black (1728-1799) found that this gas (which he called fixed air) was also produced by adding acid to chalk. He
then discovered that fixed air turned limewater milky, which led him to discovered that animals produced fixed air.
Antoine Lavoisier (1743-1794) found that breathing changed a ‘sixteenth part of [air into] a seriform acid like which is obtained from
chalk’. It was much later that the name carbon dioxide was agreed instead of seriform acid, fixed air and wild spirit. Lavoisier could
not work out where in the body carbon dioxide was produced, so thought it might occur in the tubes leading to the lungs.
