Consensus standards for histopathological examination and reporting for SLN and IFL nodes are urgently needed, particularly with regard to ultrastaging and immunohistochemistry protocols.
One of the clinical golden standards for IVD examination is the IVD height from MRI and X-ray plain film [ 84].
They were conducted according to the Standard Method for Examination of Water and Wastewater (APHA 2012).
Sampling methods and examinations were all under guidance of the standard methods for examination of water and wastewater.
The standard methods for examination of water and wastewater suggested by APHA.AWWA.WPCF (1992) were used for analysis of water samples drawn from CBM wells and coal mine heads.
The TD, COD and BOD of wastewater were analyzed before and after the electrolytic treatment following the standard methods for examination of water and wastewater (APHA 2005).
Therefore, the CBODs represents the remaining oxygen demand that is not represented by the BOD test (Standard methods for examination of water and wastewater 1998; Clair 2003).
All other analytical tests were performed according to the standard methods for examination of water and wastewater (Eaton et al. 2005).
The analysis of different physico-chemical parameters like color, odor, pH, biological oxygen demand (BOD), chemical oxygen demand (COD), total sugars, total dissolved solids (TDS), sulphates, phosphorous and calcium were analyzed for employing standard methods for examination of water and wastewater [ 30] and is shown in Table 1.
Various parameters of water quality like pH, COD, SS (suspended solids), VSS (volatile suspended solids), VFA (volatile fatty acid), total alkalinity, color, odor, turbidity, specific conductance, TDS (total dissolved solids), and total hardness were analyzed according to the standard methods for examination of water and wastewater [ 7].
