It should also include the assessment of the biotic compartment, which is usually based on relevant biotic indices (see Chapter 5 for a more detailed discussion). 1). Aquatic habitats in urban areas are particularly exposed to these pressures. The primary factors of habitat deterioration are water quality decline and flow alternations, which are particularly pronounced in urban catchments. The broad range of chemicals from point and diffused sources include toxic substances and carcinogens, fertilizers, pesticides, herbicides, household hazardous wastes, oils, anti-freeze, heavy metals, pet and yard wastes, and pseudo-hormones (see Chapter 8 for a more detailed discussion of these issues and the related potential risks for urban populations).
