An Acute Effect is an adverse effect on any living Organism which results in severe symptoms that develop rapidly; symptoms often subside after the Exposure stops.

In the environment context, acute effects refer to the immediate and often severe impacts that exposure to a chemical or pollutant can have on an organism or ecosystem. These effects are typically observed shortly after exposure and can have a wide range of negative consequences.

Here are some examples of acute effects in the environment:

1. Fish kills: High levels of toxic chemicals or pollutants in water bodies can cause fish kills. For example, spills of oil or other chemicals can create oxygen-depleted conditions in water, which can suffocate fish and other aquatic organisms.

2. Respiratory distress: Exposure to certain air pollutants, such as ozone or sulfur dioxide, can cause respiratory distress in humans and other animals. This can include coughing, wheezing, shortness of breath, and other respiratory symptoms.

3. Skin irritation: Exposure to certain chemicals, such as acids or strong bases, can cause skin irritation or burns in humans and animals.

4. Nervous system effects: Exposure to some pesticides or other chemicals can cause nervous system effects, such as seizures, tremors, or paralysis, in humans and animals.

5. Death: High levels of exposure to certain chemicals or pollutants can result in death. For example, exposure to highly toxic pesticides or industrial chemicals can be lethal to humans and other animals.

Overall, acute effects can have serious and immediate consequences for the health and wellbeing of humans and other organisms in the environment. It is important to minimize exposure to harmful chemicals and pollutants to avoid these effects.
