The influence of environmental variables on distribution of PAHs(1) The concentrations of PAHs were higher in warm temperate zone and subtropical zonethan in low temperature zone;(2) The concentration in plain, hilly land and Ya\'an mountainousregion were higher than in other places;(3) The concentration in paddy fields, dry land andforests were higher than in artificial land and grass;(4) There was positive correlation betweenthe concentration of PAHs and TOC. The correlation was more obvious for 4-rings PAHs thanfor 5-, 6-rings PAHs;(5) The concentration of PAHs in acid soils was higher than in alkali andneutral soils;(6) The concentrations in conifer and spinney forest were higher than inbroad-leaved forest.Part two: The temporal and spatial distribution characteristics of POPs at Basin-MountainTransect.

Little is known about the influence of minerals and other soil factors on the biocontrol activity of Trichoderma spp.The objectives of this study were to first evaluate the take-all–suppressive activity of T.koningii in field soils representative of the wheat-growing region in the Pacific Northwest of the United States,and then to identify abiotic edaphic parameters that are positively and negatively associated with the biocontrol activity of T.koningii in these soils.Such information will be usefulin selecting sites where T.koningii can be expected to perform optimally;in developing formulations that enhance biocontrol;and perhaps in indicating factors that favor mechanisms involved in the biocontrol activity of this strain such as antibiotic and enzyme biosynthesis.
