This article uses Danish media discourses on racialized children's schooling as a lens through which to analyse how issues of kinship and family play into nation-building processes through representations of 'the child'. The article addresses the question of the distribution of racialized children, mostly termed 'bilingual pupils', at Danish schools, which is a recurrent theme in the public debate. The media representation of this issue is mostly framed around an ideal of spreading the 'bilingual pupils' among different schools to ensure proper mixing with white Danish pupils, which is framed as securing both the educational development of the children and the prosperity of the Danish nation. Through the ideal of mixing, the nation is constituted as able to include the racialized child as an act of saving it from its heritage of racialized and classed disadvantage. A comparison with other kinds of media reporting on racialized children in Danish schooling reveals the constellation of a racialized hierarchy that works to uphold Danish whiteness and non-racism through the ideal of proper mixing. Migrant subjects who have mixed through kinship with Danish whiteness and have actively abandoned their racialized familial background seem more easily constituted as belonging in Denmark.

Microbial volatile organic compounds (MVOCs) are a variety of compounds formed in the metabolism of fungi and bacteria. Of more than 200 compounds identified as MVOCs in laboratory experiments, none can be regarded as exclusively of microbial origin or as specific for certain microbial species. Thus, the recognition of microbially contaminated areas by MVOC measurements is not successful with current methods. In this review, the basic physical and chemical properties of 96 typical MVOCs have been summarised. Of these, toxicological and exposure data were gathered for the 15 MVOCs most often analysed and reported in buildings with moisture and microbial damage. The most obvious health effect of MVOC exposure is eye and upper-airway irritation. However, in human experimental exposure studies, symptoms of irritation have appeared at MVOC concentrations several orders of magnitude higher than those measured indoors (single MVOC levels in indoor environments have ranged from a few ng/m3 up to 1 mg/m3). This is also supported by dose-dependent sensory-irritation response, as determined by the American Society for Testing and Materials mouse bioassay. On the other hand, the toxicological database is poor even for the 15 examined MVOCs. There may be more potent compounds and other endpoints not yet evaluated [ABSTRACT FROM AUTHOR]

The heavy metals cadmium, copper, lead, silver, nickel and zinc were evaluated for acute toxicity concentrations using bioassay with Daphnia magna (D. magna) and Photobacterium phosphoreum (P. phosphoreum) using Microtox™ toxicity test apparatus. Synthetic chelating agents Ethylenediaminetetraacetic acid (EDTA) and Nitrilotriacetic acid (NTA) were used for reduction of heavy metal toxicity. Copper, lead, silver were highly toxic to D. magna. Cadmium and nickel exhibited very low toxicity to P. phosphoreum. EDTA and NTA were effective in reducing metal toxicity to both organisms. However, the toxicity reduction to D. magna was significantly higher than that to P. phosphoreum. [ABSTRACT FROM AUTHOR]
