Assessment of Cytogenotoxicity of Plastic Industrial Effluent Using Allium cepa Root Tip Cells

Table 3

Mitotic characteristics of Allium cepa root cells exposed to varied amounts of plastic effluent after 96 hours.

Concentrations	T.N.C.	N.D.C.	M.I. (%)	M.Ih. (%)
Control	300	^a	32	0
15%	300	^b	24	25
30%	300	^c	20	36
45%	300	^d	15	53
60%	300	^e	10	69
L.S.D.		7.62

Significant differences between the means are indicated by the different letters along the columns. N.D.C.: number of dividing cells; T.N.C.: total number of cell count; L.S.D.: least significant difference; M.I.: mitotic index; M.Ih.: mitotic inhibition.
