The short-term symptoms of exposure to pesticides the health department should warn viewers about is that people may feel nauseous or experience dizziness following exposure to the water.

<h3>What is contamination?</h3>

Contamination of water is the process of making a water unclean or unfit for its intended purpose due to the introduction of foreign substances.

According to this question, the local news reports that chemical runoff from a nearby pesticide plant released toxic chemicals into a nearby water source.

However, the health department should warn viewers that they may feel nauseous or experience dizziness following exposure to the water.

Which subtype of type a fibers transmits signals that are interpreted and perceived as pain?

borishaifa [10]

Delta is a type of fibre that transmits signals that are interpreted and perceived as pain.

<h3>Delta fibres</h3>

A delta fibres (also known as A fibres) are a type of sensory fibre. They respond to cold and pressure stimuli, and as nociceptors, their stimulation is perceived as fast/first pain input. Because they are thinly myelinated, they transmit impulses quicker than unmyelinated C fibres but slower than other, thicker myelinated "A" class fibres.

Structure

They have myelinated axons that are thin (2 to 5 m in diameter) and have a moderate conduction velocity, or speed at which a nerve signal moves (2 to 30 m/s). These nerve fibres make up the afferent portion of the reflex arc that causes the body to "draw away" from noxious stimuli because they are linked to acute (sharp) pain (e.g. retracting your hand away from a hot stove). A part of A fibres is also linked to pressure and temperature perception (also known as "cold receptors" in mammals). Contrarily, slow-conducting, unmyelinated C fibres convey gradual, scorching pain.
