Discussion:
During the present investigation considerable effect on haematological parameters when exposed
to the toxicant, fluoride are observed as per the data pertaining to % Hemoglobin (HB), White
Blood Cells (WBC), Red Blood Corpuscles (RBC), Hematocrit (HCT), Mean Corpuscular Volume
(MCV), Mean Corpuscular Hemoglobin (MCH) & Mean Corpuscular Hemoglobin Concentration
(MCHC), revels changes which influence the haematological parameters of the fish. Hlynezak
and Ubranksa (1987) reported a significant decrease in blood hemoglobin and haematocrit of
Catfish, Cows & rats exposed to fluoride. The WBC, RBC count & Haemoglobin decreased in both
the concentration of fluoride in all treated groups. Similar results were also reported by Mishra
& Mohapatra 1987; Kristinson et al., 1997; Jagdish et al., 1998; Mandal et al., 1986; Shanthakumari
& Subramaniam 2007; Banupriya et al., 1997, Sushella et al., 2001, Kahl et. Al., 1973 and Pillai et al.,
1985) reported the inhibition of RBC on fluoride exposure. The WBC count was significantly
reduced in both fluoride concentrations similarly in another study WBC count change by fluoride
exposure to 10pp for four month rats by Eren et al, (2005).
In this investigation of RBC, PCV, HB %, MCH, MCHC was found decreased. Similar reports
were made by Ramanujaam & Mohanty (1977) also reported decreases in RBC, PCV, HB %, MCH,
MCHC due to thiodon. Bhatt and Farswan (1992) observed that RBC, WBC, HB%, PCV decreased
while ESR increased, due to plant toxicant Barilius bendalensis (Hem). In the present investigation
we found significant increase in MCHC, WBC cell count. Similar observation was made by Nath
and Banerjee (1995) observed a significant increase in MCHC, WBC and ESR in Heteropheustes
fossils due to toxicity of dimithion. A significant decreased in the Hb%, RBC and PCV% was
noticed on exposure of Catla catla to Malathion and Dichlorofos (Srinivas et al., 2001). The MCV
