Table 2

Acute and chronic ecotoxicity testes results with Daphnia simillis (A) and Ceriodaphnia dubia (B) respectively, applied to water samples obtained from four urban drainage channels (Tombo, Enseada, Perequê and Iporanga) in the city of Guarujá, São Paulo, Brazil

 
 

The results are presented considering two different seasonal periods: rainy season (January and March of 2018); and dry season: (May and July of 2018). These tables also show: (i) rates of immobility of controls and beaches (total of immovable organisms and their percentages); (ii) toxicity classification for the acute and chronic tests (i.e. non-toxic, signalled in green; toxic: signalled in yellow; and very toxic, signalled in red. For more details, see Materials and Methods). Note: *Tombo channel could not be sampled in the July campaign (dry season) because the water course was dry.
