The Mann Kendall test, which is recommended by the World Meteorological Organization (WMO), was used, since the succession of values occurs independently and the probability distribution remains the same in the case of stability of a time series (Back, 2001).
The Mann Kendall test indicated an increase in annual rainfall in Veranopolis of 6.34 mm per year (p < 0.01) (Figure 4A).
Finally, the Seasonal Kendall Test for Trend was used to determine if a linear trend of atrazine over time throughout the state exists.
In this study statistical significance trend analysis was done by using Man- Kendall test while for the magnitude of trend was determined by non- parametric Sen's estimator method.

The Mann Kendall test was used to determine trends on individual stations; results are summarized in Table 2.
Trends in mean monthly temperatures were analyzed with the Seasonal Kendall test for trend (Hirsch and Slack, 1984; Helsel et al., 2006).
These steps essentially involve: (i) testing the serial correlation effect; (ii) Trend detection by Mann Kendall test (iii) Estimate the trend value (changes in time series variables) by Sens estimator.
Mann Kendall test is a statistical test widely used for the analysis of trend in climatologic (Tabari et al.
