    Annotation Description of chemical characteristics and toxicity testing of whole sediment and elutriate have been performed with 35 samples taken during the monitoring of rivers in the Middle Volga region (Tatarstan, Russia) in 2013. The locations analyzed are sites associated with agriculture, forestry, and petroleum hydrocarbons (oil) production. The toxicity tests include: (1) Chlorella vulgaris (algal) elutriate test, (2) Paramecium caudatum (ciliate) elutriate test, (3) Daphnia magna (cladoceran) whole sediment toxicity test, and (4) Heterocypris incongruens (ostracod) whole sediment toxicity test. The concentrations of metals in 43% of sediment samples have been found to exceed probable effect concentration sediment quality guidelines (SQGs). However, the concentrations of polycyclic aromatic hydrocarbons (PAHs) and organochlorine pesticides have turned out to be below SQGs in most sites. The correlation analysis has shown metal toxicity to daphnid reproduction and ostracod growth (R2= 0.34
