Impact of chlorophenols and heavy metals on soil microbiota: their effects on activity and community composition, and resistant strains with potential for bioremetiation

Pollution by toxic compounds is one of the most relevant environmental damages to ecosystems produced by human activity and, therefore, it must be considered in environmental protection and restoration of contaminated sites. According to this purposes, the main goal of this doctoral thesis has been to analyse the impact of several chlorophenols and heavy metals on the microbial communities of two typical Mediterranean soils. The ecological risk concentrations of each pollutant, which have been determined according to respirometric activity and changes in the microbial community composition, and the factors that influence on their effective toxic concentrations (bioavailable pollutants) have been analysed in order to predict their potential impact on different soil ecosystems and provide scientific data for the regulation of the soil protection policies. Moreover, resistant microorganisms with pollutant removal capacities have been isolated from artificially contaminated soil microcosms and tested in axenic cultures, to infer their potential usefulness for bioremediation.

A study of the TAGS, an enduring teaching tool: teachers’ perspectives on the Teacher Assessment of Grammatical Structures teaching practices and application

This paper is studied look at the Teacher’s Assessment of Grammatical Structures (TAGS), Teacher Assessment of Spoken Language (TASL), and Cottage Acquisition Scales for Listening, Language and Speech (CASLLS) criterion-referenced language assessments as well as an inquiry into how teachers of the deaf use the TAGS currently as a teaching tool.
