Water Health
The main sources of water pollution include both inorganic and organic wastes, heat from industries, petroleum compounds, urban wastes, agricultural wastes, pesticides, and acid mine drainage. Among these pollutants mercury, perflouoroalkyls (PFAs e.g. perchlorate), tributyiltin, dioxins and polychlorobiphenyls (PCBs) are present.
Water pollution may affect health since many of them are highly lipophilic, and bioaccumulate along the food chain. Moreover, since water is an important raw material in the fresh produce chain, it may contaminate food through irrigation and application of pesticides and fertilizers, but also as a transport medium and for cooling and washing in postharvest practices.
For this reason it is essential to monitor water quality at each step in the food chain.
