Correction to: Environ Sci Pollut Res (2015) 22:397–414 https://doi.org/10.1007/s11356-014-3346-1 As corresponding author, while going through higher research in this area, it is found that the formula for Hurst exponent given in equation (13) on page no. 401 is wrongly written. Accordingly, following corrections suggested: ABSTRACT &
On page 397, in Abstract All water quality parameters at every site follows persistent behaviour
Hurst exponent is related to the exponent a by a relation H¼1− α2 On page 401 & & & &
instead of Brownian motion (true random walk) behavior exists at different sites for BOD, AMM, and total Kjeldahl nitrogen (TKN).

Hurst Exponent is defined as slope of regression line of log-log curve of any time series with time instead of the slope of the regression line. Hurst exponent (H) can be computed on the basis of power law decay i.e. pðkÞ¼Ck−α where C−constant;pðkÞ −autocorrelation function with lag k
Reference [1]-[3] clearly states the above-mentioned formula. If 0
