BACKGROUND Phthalates are endocrine-disrupting chemicals that influence thyroid hormones and sex steroids, both critical for brain development. AIM We studied phthalate concentrations in house dust in relation to the risks of developing autism spectrum disorder (ASD) or developmental delay (DD). METHODS Participants were a subset of children from the CHARGE (CHildhood Autism Risks from Gene...

BACKGROUND Environmental pollutants are thought to be one of major triggers of atopic dermatitis (AD). OBJECTIVE We attempted to evaluate the clinical effects of environment with low indoor pollutant levels on AD management. METHODS Fifty-one children (mean age 1.7 years) with moderate to severe AD who failed to show improvement with conventional management were recruited. Disease severity ...

It is still unknown whether the organobromine compounds in indoor environment of gyms would affect human health. This study tried to investigate PM2.5 and indoor-dust levels polybrominated dibenzo-p-dioxins/furans (PBDD/Fs) diphenyl ethers (PBDEs) then further assess health risks gym users employees who were exposed these organobromines through inhalation ingestion. The be examined for PBDD/DF/...

UNLABELLED House-dust mites (HDMs) are an important source of allergens that are reputed to act as a trigger for atopic disease. Climatic conditions in parts of South Africa are not suitable for their proliferation, and there is doubt whether they occur on the Highveld. We studied whether HDMs occur in homes in Bloemfontein, Free State. METHODS Ten houses were sampled over a 1-year period. Du...

In this paper, we review recent data for brominated flame retardants (particularly BDEs, HBCD and TBBP-A) in samples from the European and Asian environments, including recent temporal trend studies. Research is active and we cite over 100 studies published during 2005-2007. Environmental compartments studied comprise the atmosphere, indoor and outdoor air, sewage sludges, soils and sediments a...

We present here the draft genome sequences of Dermacoccus nishinomiyaensis strains UCD-KPL2534 and UCD-KPL2528, which were isolated at an indoor track facility in Medford, MA, USA (42.409716, -71.115169) from an exit door handle and settle dust, respectively. The genome assemblies contain 3,088,111 bp in 58 contigs and 3,162,381 bp in 100 contigs, respectively.

Jharia coal-field holds unequivocal importance in the Indian context as it is the only source of prime coking coal in the country. Haphazard mining over nearly a century has led to environmental changes to a large extent such as degradation in the quality of air, water, soil, changes in landform, land-use/land-cover and vegetation distribution. Environmental impact assessment is a process to as...

We adapted an indoor multimedia fugacity model to consider emissions and fate of polybrominated diphenyl ethers (PBDEs) and to understand the variability of indoor concentrations. The model was applied to an office in which an 80% decrease in PBDE air concentration was observed after an old computer was exchanged with a newer one. PBDE-impregnated polyurethane foam (PUF) and carpet were treated...

BACKGROUND Domestic endotoxin enhances airway inflammation and increases asthma severity in Caucasian children, but little data are published on indoor endotoxin exposure in Asian countries. This study investigated house dust endotoxin and Der p 1 levels in Hong Kong families with asthmatic children, and their effects on asthma severity. METHODS 115 asthmatics from a pediatric clinic underwen...
