Acute sensitivity to Nitokra sp benthic copepod to potassium dichromate and ammonia chloride
(2012)
The present study assesses acute toxicity of non-ionized ammonia and potassium dichromate using the estuarine benthic copepod Nitokra sp from laboratory cultures. Bioassays with non-ionized ammonia sensitivity were carried ...
Use of newborn Girardia tigrina (Girard, 1850) in acute toxicity tests
(2001)
Acute toxicity tests, exposing Girardia tigrina to potassium dichromate (K2Cr2O7), showed good reproducibility. The 95% confidence intervals among tests were 0.0262±0.0141 g for 48-h LC50 (N=6) and 0.0129±0.0078 g for 96-h ...
Sensitivity of the marine benthic copepod tisbe biminiensis (copepoda, harpacticoida) to potassium dichromate and sediment particle size
(2009)
For the future use of the marine benthic copepod Tisbe biminiensis in solid-phase sediment toxicological bioassays, the present study investigated the effect of muddy sediment from the Maracaípe estuary (northeastern ...

Reciclagem do crômio de resíduos químicos provenientes da determinação de carbono oxidável em fertilizantes orgânicos
(Sociedade Brasileira de Química, 2011)
This work proposes a separation, recovery and reuse procedure of chemical residues with chromium. This residue was generated by the determination of oxidizable carbon in organic fertilizers samples. The Cr(VI) of the residue ...
