Environmental concentrations and other environmental variables tend to have positive skewness. Therefore, environmental statistics texts often focus on positive skew distributions such as the log-normal, gamma, and Weibull. Discussions of distributions with nonnormal kurtosis are somewhat more scarce. 

A fitted distribution should be evaluated using graphical methods as well as statistical goodness-of-flt (GoF) tests. Appropriate procedures are available in texts on environmental statistics and risk assessment (e.g., Gilbert 1987 Helsel and Hirsch 1992 Millard and Neerchal 2000). It is suggested that USEPA (1998) be consulted regarding a number of practical considerations.

The statistical characteristics of different parts of East Asian domain were extracted from both national and international sources (see, for example, Environmental Statistics Yearbook, 1998. Ministry of Environment, Republic of Korea, or UNESCO, 1978 ESCAP, 1998). Data on content of nitrogen species in river waters were selected both from our own and literature studies. 

Assessment of biological fixation (nonsymbiotic only, since the area under symbi-otically fixed crops was very small in ROK) was carried out using the following data (Environmental Statistics Yearbook, 1998 Cleveland et al, 1999 Zhu et al, 1997). 

To calculate these values, the following data were used (Environmental Statistics Yearbook, 1998) ... 

In its turn, this leads to further pollution of drinking water, eutrophication of surface waters, mainly, water reservoirs, and increasing input of NtO to atmosphere. For instance, the DIN contents in many South Korean water reservoirs are 4-10 mgN/L in summer season and most of these reservoirs are eutrophied (Environmental Statistics Yearbook, 1998). 

Taking into account the values of various input/output items of biogeochemical N cycle as well as literature data (Environmental Statistics Yearbook, 1998 Park, 1998 Ereney, 1996 Mosier et al, 1998 Zhu et al, 1997), the regional mass budget was calculated for the whole South Korean territory (Table 17).

During the last decade, there has been a growing global requirement for meaningful and accurate statistics on pesticide use. EUROSTAT, the statistical office of the European Communities, first published data on sales of pesticides in the environmental statistics yearbook for 1991, and further work was undertaken as part of the Dobris report (Stanners and Bourdeau, 1995) to produce a coordinated statistical appendix on pesticide use. Data, however, were poorly available, with specific information only obtainable for certain active substances or countries. It was also found that, in most cases, data were not very accurate, and different definitions of pesticides and their classification between countries made comparison difficult.
