With a regularly conducted vertically high resolved analysis of groundwater as well as of sediment samples at a site in Düsseldorf over 4 years, dynamics of the vertical expansion of the contaminant plume and the maximal contaminant concentrations could be revealed, although when only small fluctuations of the groundwater table took place. Even within a very short time span (2 weeks), small changes in the contaminant distribution with accompanied sulfide occurrence, a degradation product, could be detected, that shows an unexpected fast adaption possibility of the microorganisms. However, 2008 a collapse of toluene biodegradation was observed, supporting the assumption that dynamics inhibiting the microbial degradation rather than enhancing as soon as they are stronger.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838123530\"\u003e\u003ch3\u003eFocus on microbial activities\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783838123530","offer_id":39456637943901,"sku":"9783838123530","price":69.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/f9f78d6e-b471-4ce6-a308-9987aa6d37ec.jpg?v=1776318593","url":"https:\/\/shop.autorenwelt.de\/en\/products\/spatial-temporal-dynamics-in-a-tar-oil-contaminated-aquifer-focus-on-microbial-activities-von-anne-bayer","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
