Peroxisomes' cell membrane have enzymes that do get rid of harmful, toxic materials within the cell. Additionally, peroxisomes help to break down fatty acid chains and alcohol. They are similar to lysosomes in ways, except the enzymes found in peroxisomes work in oxygen-rich areas, whereas lysosomes work in areas with less oxygen.
Interestingly, peroxisomes also produce toxic material--hydrogen peroxide. However, they are well-evolved enough to quickly breakdown the hydrogen peroxide into oxygen and water, which is harmless to the cell.

What functions isolate particular chemical activities from the rest of the cell?
Peroxisomes isolate particular chemical activities from the rest of the cell. Peroxisomes are a type of microbody that helps the body break down large molecules and detoxify hazardous substances.
What detoxifies harmful substances like alcohol formaldehyde and disarms free radicals?
Peroxisome "Peroxisomes, like lysosomes, are enzyme-containing sacs. However, their oxidases have a different task. Using oxygen, they detoxify a number of harmful substances, most importantly free radicals. Peroxisomes are particularly abundant in kidney and liver cells, cells that are actively involved in detoxification." (Credit to Authors Elaine N. Marieb and Susan J. Mitchell)
Do hepatocytes detoxify?
