1. Bioaccumulation

2. Bioaccumulation is the accumulation of substances, such as pesticides or other chemicals in an organism. It occurs when an organism absorbs a toxic substance.

3. How to prevent Bioaccumulation: Do not put harmful substances (e.g., used motor oil) into the water system or storm drains. Contact a recycling center for methods of safe disposal. Avoid toxic chemical pesticides. Eat certified organic foods when possible. Always wash fruits and vegetables before consuming. Avoid fishing or spending time in contaminated areas. Avoid plastics. Use cleaning products that are gentle on the environment. Choose fish wisely, as many contain unsafe levels of toxins. This requires continuous improvement in every phase of operations in which oil is produced, transported, stored or marketed.

4. Bioaccumulation is also a problem for humans, as well as fish. When humans eat the fish, we digest the pesticides the fish contained. Then the pesticides then accumulate in our bodies and can cause diseases. It can effect the nervous system in all living organisms.

5. Bioaccumulation is caused by when ships transporting oil sometimes leak into the ocean. When the fish swim by they absorb the chemicals and they can die from it. Or they can be caught and eaten. If eaten by a living organism diseases could be transmitted from the chemicals.
