Toxicity Assessment of Expired Pesticides to Green Algae Pseudokirchneriella subcapitata

Differential Response of Green Algal Species Pseudokirchneriella subcapitata, Scenedesmus quadricauda, Scenedesmus obliquus, Chlorella vulgaris and Chlorella pyrenoidosa to Six Pesticides

This work examines the effects of six pesticides on five green algae: Pseudokirchneriella subcapitata, Scenedesmus quadricauda, Scenedesmus obliquus, Chlorella vulgaris and Chlorella pyrenoidosa. The results indicate that the decreasing order of the average toxicity to five algae was: fluazinam > propineb > maneb > mancozeb > zineb > bromoxynil octanoate. however, according to sensitivity magni...

Toxicity assessment of pesticides to Pseudokirchneriella subcapitata under air-tight test environment.

This paper presents the toxicity data of seven pesticides including atrazine, parathion, dichlorvos, malathion, fenthion, 2-methyl-4-chlorophenoxyacetic acid, and pentachlorophenol on Pseudokirchneriella subcapitata based on a new algal toxicity testing technique conducted under air-tight environment. The dissolved oxygen production and the cell density were adopted as the response endpoints. M...

The combined toxic effects of nonpolar narcotic chemicals to Pseudokirchneriella subcapitata.

This paper presents the toxicity data of 10 nonpolar narcotic chemicals on Pseudokirchneriella subcapitata (green algae) assessed by a new algal toxicity testing technique conducted under air-tight environment. Based on DO production, median effective concentration (EC50) varies from 1.73 mg/L (1-octanol) to 8,040 mg/L (2-propanol). The endpoint of algal growth rate reveals similar sensitivity ...

Comparative Sensitivity of Eight Freshwater Phytoplankton Species to Isoprocarb, Propargite, Flumetralin and Propiconazol

This work compared the sensitivity of three cyanobacteria (Anabaena flos-aquae, Microcystis flosaquae and Mirocystis aeruginosa) as well as five green algae (Pseudokirchneriella subcapitata, Scenedesmus quadricauda, Scenedesmus obliquus, Chlorella vulgaris and Chlorella pyrenoidosa) to four pesticides through 96h short-term chronic tests. The results showed that the toxicity of the pesticides t...

Differences in the effects of metals on growth of two freshwater green algae (Pseudokirchneriella subcapitata (Korshikov) Hindak and Gonium pectorale Müller).
