Abstract: Microalgae are widespread organisms which can be used as bioindicator for pesticides in water. The inhibition of photosynthesis by pesticides, which leads to the change in fluorescence emission can be used as the parameter of detection. In this study, the responses of microalgae Chlorella vulgaris to two pesticides- atrazine and 2,4-dichlorophenoxyacetic acid (2,4-D) were reported. For the optimized responses, C. vulgaris from day-3 culture with approximate 3.5 x 106 cells was immobilized with 0.5 % of agarose, which later exposed to different concentrations of atrazine and 2,4-D for 15 minutes respectively. The results showed C. vulgaris responded to both pesticides from the range of 0.001 mg/L – 10.000 mg/L. The results confirmed the potential of C. vulgaris as bioindicator for both pesticides

Abstract: The Tokyo Electric Power Company's, Fukushima Dai-ichi nuclear power plant in Fukushima-Ken (Fukushima Prefecture), Japan, was destroyed in March 2011 by a massive magnitude 9 earthquake (centred offshore to the northeast of Honshu Island) and by the subsequent historic tsunami of March 11, 2011. Because of the nuclear meltdown, hydrogen-explosion damage to the buildings that housed the reactors, and the contamination of the cooling water from the reactor cores, large quantities of radioisotopes were emitted into the atmosphere and adjacent seawater. Fishing is currently restricted off the coast of Fukushima-Ken because intermittent surveys have found part of the fishery products still contain high levels of radioisotopes. The Tokyo University of Marine Science and Technology has measured radioisotope levels in fishery species off Iwaki-Shi(Iwaki City), Fukushima-Ken(located south of the former nuclear power plant); these data could be used to understand the relationship between the ac
