“…This is a preliminary observation and the test species were collected near final sewage mixing area (Khardah) compared to non-sewage mixing area (Kalyani). It is suggesting to know the pollution load by analysis of physico-chemical parameters in the particular area and correlate with the present study of biomonitoring of other sensitive as well as tolerant algae species (Rai, 1978).…”

“…The inorganic and organic water pollution monitoring by analysis of physico-chemical parameters of waterbodies is a continuous effort to know water quality criteria by regulatory authorities and recommended different treatment facilities. Less attention has been found on biomonitoring in algal species as potent tool at the bank of river Ganga, West Bengal, scattered biomonitoring works on Ganga river, different parts of India and other rivers have been supported the present research (Rai, 1978 Besides these previous studies, it was also known that the test organism has alter their morphological features during winter and spring for the reproduction (Chalotra et al, 2013). This is a preliminary observation and the test species were collected near final sewage mixing area (Khardah) compared to non-sewage mixing area (Kalyani).…”

“…It is well supported by many researchers that algae species are suitable indicators of pollutants (Vyasand Kumar, 1968;Rai, 1978;Ahluwalia et al, 1989;Jindal and Sharma, 2011;Halder, 2015). Moreover, it was reported that the water of river Ganga is mixed with pollutants by domestic wastewater, industrial effluent, agricultural runoff etc.…”

“…It was documented that several types of algae species are inhabiting at the bank of river Ganga (Indian Institute of Technology Report, 2012) but no work has been attempted the biomonitoring with special reference to morphological alterations as indicator algae species (Zygnema sp.) at the bank of river Ganga, West Bengal while few works on algae have been reported on river Ganga bank at Indian part and other riverine ecosystem (Rai, 1978;Jindal and Sharma, 2011;Singh and Chaudhary, 2011;Chalotra et al, 2013;Halder, 2015) in relation to sensitive and tolerant species.…”

ABSTRACT. The present study aims to detect morphological abnormalities in Zygnema sp. because this test species have high adaptive capacity in unfavourable environmental stress. This alga is inhabited at the suburban bank of river Ganga, West Bengal, India. The study was done at experimental sites, downstream at Khardah near sewage water mixing area was compared with upstream control site Kalyani as no sewage water discharge. External and internal abnormal morphology such as undulating or wavy and extra outgrowth on cell wall, sometimes bending inwardly and outwardly as external deformities while internal anomalies such as pigment loss, nucleus was in circular, rectangular, oval and amoeboid shapes, also vacuolated and trilobed, broom like chloroplasts and central part of the thallas dried in between two segments. It was observed that this test species was surviving and well adapted with above mentioned deformities. The present preliminary study with Zygnema sp. can be utilized for in situ and ex situ indicator species for riverine biomonitoring. Further research may be relevant to know both tolerant and sensitive algae species inhabited at the river Ganga bank alongwith biochemical and genetic parameters. The present work is suggesting that other inhabiting algae and this adaptive test species can be used for bioremediation of pollutants.
