Report of the Inter-laboratory Comparison Project 2009

The Inter-laboratory Comparison Project 2009 report from the Acid Deposition Monitoring Network in East Asia (EANET) reviews how well laboratories in 13 countries measured environmental samples. It covers wet and dry deposition, soil, and inland aquatic environments. The report includes test results, comparisons to known values, and data quality checks. It aims to improve accuracy and consistency in lab analyses and provides recommendations to help labs strengthen their methods and reliability for future monitoring.
