====Pollution====
Synthetic musks are pleasant in smell and relatively inexpensive, as such they are often employed in large quantities to cover the unpleasant scent of laundry detergents and many personal cleaning products. Due to their large-scale use, several types of synthetic musks have been found in human fat and milk,<ref>{{cite journal |vauthors=Duedahl-Olesen L, Cederberg T, Pedersen KH, Højgård A |title=Synthetic musk fragrances in trout from Danish fish farms and human milk |journal=Chemosphere |volume=61 |issue=3 |pages=422–31 |date=October 2005 |pmid=16182860 |doi=10.1016/j.chemosphere.2005.02.004 |bibcode=2005Chmsp..61..422D }}</ref> as well as in the sediments and waters of the [[Great Lakes]].<ref>{{cite journal |vauthors=Peck AM, Linebaugh EK, Hornbuckle KC |title=Synthetic Musk Fragrances in Lake Erie and Lake Ontario Sediment Cores |journal=Environ.

These pollutants may pose additional health and environmental problems when they enter human and animal diets.

====Species endangerment====
The demands for aromatic materials such as sandalwood, agarwood, and musk have led to the endangerment of these species, as well as illegal trafficking and harvesting.
