87
If an indivs are exposed to helath care wastes susch as medical staff, in- and out- patients etc.
Are they potentially at risk of being injured or infected?
Yes duh ofc
88
Why does Incinerating waste causes problems?
Incenerating means burning
because plastics tend to produce toxic substances, such as DIOXINS, when they are burnt.
Gases from incineration may cause air pollution and contribute to acid rain, while the ash from incinerators may contain heavy metals and other toxins.
