How does dust affect the environment?
Impacts on the environment and society But dust also has many negative impacts on agriculture, including reducing crop yields by burying seedlings, causing loss of plant tissue, reducing photosynthetic activity and increasing soil erosion.
Is scissors hazard or risk?
The biggest safety hazard involved in using regular scissors is the risk of laceration from overly-sharpened blades. Metal scissors tend to dull quickly. As a result, they’re manufactured to be overly sharp in an attempt to extend the tool’s longevity. Using such a pair of scissors increases the risk of laceration.

Why dust is a pollutant?
Dust is a pollutant because (i) Dust consists of suspended particles. Inhalation of dust causes lots of discomfort including allergic asthma, bronchitis, cold or cough. (ii) It reduces intensity of light. (iii) Dust particles settle over leaf and can block stomata and reduce gaseous exchange in plants.
What happens if I inhale dust?
You may not think it’s a big deal when you breathe in dust, but for some people, it could bring on a lung disease called hypersensitivity pneumonitis. It’s an allergic reaction to particles in the dust, and it can cause symptoms like coughing and shortness of breath.
Is dust a flammable substance?
Most types of dust are flammable, though it will depend on the type of dust. Due to the extremely high ratio between the surface area of the particles and their total volume (because dust particles are so small), it is often very easy to get dust to burn, even when the material is not otherwise very flammable.
Why is dust so flammable?
Mechanism. Dusts have a very large surface area compared to their mass. Since burning can only occur at the surface of a solid or liquid, where it can react with oxygen, this causes dusts to be much more flammable than bulk materials.
Can house dust cause fire?
Dust can be a fire hazard if it collects near floor heaters, electronics, and sockets. If sparks fly, dust piles can ignite and cause a fire. Regular dusting and vacuuming with a hose can significantly reduce the amount of dust that lingers near your electrical outlets and appliances.
