The objective of this study was an assessment of the pesticide pollution level in soil in frame of old pesticide storage near Balceana village and surrounding agriculture territory. The concentration of obsolete pesticides was compared with other four sites from Hincesti region of Moldova. GC an GC/MS techniques were used with appropriate sample preparation technology. The spatial analysis showed a strong pollution impact to surrounding agriculture territory near Balceana old pesticide storage. The distance from 100 to 500m from site boundry is characterized by high pollution level of DDTs (more that 3 times higher that MAL for soil). The high HCHs concentration is determined only in frame old pesticide storage. Were determined that principal ways of the pesticide fate into the environment is dispersion by wind with dust soil material. The anomaly with high DDTs concentration is explained by the insufficient management by the utilisation of this chemical in the past. Borehole showed a principal DDTs pollution to the depth near 1 m which do not reach ground water level. The investigated territory needs a control of the agriculture production and aother land use.
