The technologies tested were selected in order to deliver high removal efficiencies with respect to organic matter, nitrogen and phosphorus. They also had to fulfil requirements concerning robustness, nutrient recycling, use of natural resources, economy, user-friendliness and hygiene. The systems can be divided into package plants, urine separating systems, blackwater separating systems and chemical precipitation as a supplement to sand filter beds. All of the systems were able to remove more than 90% of phosphorus and more than 90% of organic matter. Concerning package plants, it is necessary to have reliable dosing equipment and frequent checks to achieve long-term phosphorus removal. The source separation systems require well-informed and motivated users to a...

Furthermore, we would clarify the influence of possible effect modifiers. Non-smoking welders with (N = 74) and without (N = 32) work-related symptoms the last month were enroled. Symptoms and work tasks each day for three two-week periods during 1 year were obtained. Respirable dust (RD) was measured 1 day each period for each worker. The personal daily exposure was assessed as: (1) days at work, (2) welding time and (3) estimates of RD from welding and grinding, calculated from diary entries and measurements. Only 9.2 % of the particle measurements exceed the Swedish occupational exposure limit (OEL; 5 mg/m(3)). Days at work increased the risk of symptoms studied: eyes: 1.79 (1.46-2.19), nasal: 2.16 (1.81-2.58), dry cough: 1.50 (1.23-1.82) and wheezing and/or dyspnoea: 1.27 (1.03-1.56; odds ratio, 95 % confidence interval).

In existing models the cross-dose from nearby loops of the small intestine is not taken into consideration. The aim of this investigation was to develop a general model for calculating the absorbed dose to the radiation-sensitive cells in the small intestinal mucosa from radionuclides located in the small intestinal wall or contents. A model was developed for calculation of the self-dose and cross-dose from activity in the intestinal wall or contents. The small intestine was modeled as a cylinder with 2 different wall thicknesses and with an infinite length. Calculations were performed for various mucus thicknesses. S values were calculated using the EGS4 Monte Carlo simulation package with the PRESTA algorithm and the simulation results were integrated over the depth of the radiosensitive cells. The cross-organ ...

Methods: Included in the study were 159 rubber exposed and 118 not-rubber exposed workers. Lung function was analyzed as forced vital capacity percent of predicted and forced expiratory volume in 1 second percent of predicted. Levels of 2-thiothiazolidine-4-carboxylic acid (a marker of carbon disulfide and vulcanization fumes) was assessed with liquid chromatography tandem mass spectrometry. Polymorphisms in glutathione-related genes were analyzed by Taqman-based allelic discrimination and ordinary polymerase chain reaction. Results: There was an association between increasing levels of 2-thiothiazolidine-4carboxylic acid and impaired lung function among exposed workers. The association was modified by glutathione S-transferase alpha 1 (GSTA1)-52 and GSTP1-114. GSTM1 had an influence on lung function among unexposed workers. Conclusions: There may be a risk of impaired lung function in contemporary rubber workers. Genemodifying effects may be considered in risk assessments. (J Occup Environ Med. 2008;50:1006 -1012

Polymorphisms in genes, which are involved in the defense against reactive oxygen species and metabolism of toxic substances present in the vulcanization fumes, were analyzed. One hundred and forty-five exposed and 117 unexposed workers were included in the study. Medical and occupational histories were obtained in structured interviews. Symptoms were recorded and immunologic markers analyzed in blood. Polymorphisms in glutathione-related genes (glutamate cysteine ligase catalytic subunit (GCLC)-129, glutamate cysteine ligase modifier subunit (GCLM)-588, glutathione S-transferase alpha 1 (GSTA1)-52, GSTM1*O, GSTP1-105, GSTP1-114, and GSTT1*O) were analyzed by Taqman-based allelic discrimination and ordinary PCR. A protective effect of GSTA1-52 (G/A + A/A) genotype on symptoms and immunologic cells, in particular among exposed workers, was suggested. Exposed workers with GSTT1*O had increased risk of nosebleed compared to exposed workers with GSTT1*1. Exposed workers with GSTP1-105 (ile/val + val/val) had decreased levels of total immunoglobulin E (IgE) compared to exposed workers with GSTP1-105 ile/ile. GCLC-129 variant genotype demonstrated increased levels of immunologic cells among exposed workers, although statistical significance was not reached. Our data indicate that hereditary factors influence the susceptibility to symptoms and the immunologic response of workers in the rubber industry.

Included were 25 male, non-smoking welders. Each welder was sampled twice; before exposure (after vacation), and after 1 month of exposure. From the welders (14 symptomatic, of whom 7 had asthma-like symptoms), RNA from induced sputum was obtained for gene expression analysis. Messenger RNA from a subset of the samples (n = 7) was analysed with microarray technology to identify genes of interest. These genes were further analysed using quantitative PCR (qPCR; n = 22). By comparing samples before and after exposure, the microarray analysis resulted in several functional annotation clusters: the one with the highest enrichment score contained "response to wounding", "inflammatory response" and "defence response". Seven genes were analysed by qPCR: granulocyte colony-stimulating factor 3 receptor (CSF3R), superoxide dismutase 2, interleukin 8, glutathione S-transferase pi 1, tumour necrosis factor alpha-induced protein 6 (TNFAIP6), interleukin 1 receptor type II and matrix metallopeptidase 25 (MMP25). Increased levels of CSF3R, TNFAIP6 and MMP25 were indicated among asthmatic subjects compared to non-symptomatic subjects, although the differences did not reach significance. Workers' exposure to welding fumes changed gene expression in the lower airways in genes involved in inflammatory and defence response. Thus, microarray and qPCR technique can demonstrate markers of exposure to welding fumes and possible disease-related markers. However, further studies are needed to verify genes involved and to further characterise the mechanism for welding fumes-associated lower airway symptoms.

These levels were used as an index substance for vulcanization fumes, as well as a biomarker for polycyclic aromatic hydrocarbons (PAHs). The risk of symptoms and changed levels of immunologic markers were investigated in relation to the 1-HP levels.

The experiments were performed by comparing plots that had received additions of nitrogen-enriched water (35 kg N ha−1 annually since 1991) by means of sprinkling system with plots only receiving ambient (about 12 kg N ha−1 per year) nitrogen deposition. The above-ground EM sporocarp production was recorded in 1992–1996; the number of mycorrhizas and their gross morphotype differentiation were registered in 1992–1995, and the mycobionts of randomly selected mycorrhizas were identified in detail by ITS-RFLP analyses in 1994. The addition of nitrogen did not affect the species richness or diversity of below-ground EM fungal species. In total, 50 RFLP-taxa were distinguished, of which 15 occurred in both treatments and 29 occurred only in single plots. However, the species richness and diversity of sporocarps of EM species were lower in the nitrogen-treated stand. Spatial distribution patterns of below-ground EM fungal taxa were assessed at various scales, from centimetres to tens of meters. Aggregations of mycorrhizal morphotypes were apparent on the centimetre scale, whereas no apparent spatial pattern could be discerned in the below-ground community on the meter scale. In accordance with the survey of below-ground taxa, the sporocarp analysis revealed that most species were rare, and only a few were widely distributed. The number of mycorrhizas per unit area differed among years, whereas the relative abundance of Cenococcum geophilum and Piloderma croceum appeared to be stable.

We draw from a project, Children as co-researchers of foodscapes, where we have been working with children as co-researchers, using basically ethnographic methods, and as co-designers in a collaborative design effort. This article focuses on the findings from a theoretically inspired perspective, using the concept of foodscapes. These are food-related structures of different kinds, which evolve as the child explores them and where children as food consumers are generated. In this article, we highlight the scapes of taste, routines, people, things, commerce, child (as opposed to adult) and health and give brief accounts of the way the children related to them. Finally, we turn to the benefits of working with foodscapes for a better understanding of children's becoming as food consumers in the intersection of various foodscapes. This article is based on data gathered by the children, but also on our fieldwork notes and observations following the children in their foodscapes.
