  • Indoor air quality in primary schools

    The indoor air quality (IAQ) in classrooms is expected to play a key role in the assessment of the effects of the children's personal exposure to air pollution since they spend on average 7–11 h per weekday at school. A statistical treatment was conducted over a database of indoor air parameters and the primary schools where these parameters were sampled (urban area of Lisbon, Portugal). The aim ...

  • Feasibility Study of an Express Assessment Protocol for the Indoor Air Quality of Air-conditioned Offices

    It is costly to sample all major toxic pollutants in community air. Sampling should be conducted based on an assessment strategy and monitoring planning. Assessment methods that rely on monitoring some representative pollutants have been proposed variously at different times. In Hong Kong, the Environmental Protection Department (HKEPD) launched an Indoor Air Quality (IAQ) certification scheme to ...

  • Case study of odor and indoor air quality assessment in the dewatering building at the Stickney Water Reclamation Plant

    Indoor air quality (IAQ) and odors were determined using sampling/monitoring, measurement, and modeling methods in a large dewatering building at a very large water reclamation plant. The ultimate goal was to determine control strategies to reduce the sensory impacts on the workforce and achieve odor reduction within the building. Study approaches included: (1) investigation of air mixing by ...

  • Vapor intrusion and indoor air quality due diligence during property transactions

    Vapor intrusion (i.e. the migration of volatile chemicals from contaminated soil and/or ground water through the subsurface into overlying building structures) as a contributing indoor air has become a growing concern for property owners and prospective purchasers in recent years as it can cause significant indoor air quality problems. This is largely due to the increased focus on this issue by ...

  • Differential impacts of smoke-free laws on indoor air quality

    The authors assessed the impacts of two different smoke-free laws on indoor air quality. They compared the indoor air quality of 10 hospitality venues in Lexington and Louisville, Kentucky, before and after the smoke-free laws went into effect. Real-time measurements of particulate matter with aerodynamic diameter of 2.5 µm or smaller (PM2.5) were made. One Lexington establishment was excluded ...

  • Improving air quality in the office

    Most people spend the main part of their day indoors – in the home, school or office environment. Focusing specifically on improving air quality in the office and workplace setting, we are looking at the key potential sources of pollution which impact upon air quality and employees’ health. Examples include, outdoor air (particularly relevant if the workplace is next to a busy road), ...

  • Assessment and Remediation of Vapor Intrusion to Indoor Air, South Mesa State Superfund Site Gilbert, Arizona

    Abstract Vapor intrusion to indoor air from volatile organic compound (VOC) contamination in the subsurface is increasingly becoming a more important exposure pathway when developing site conceptual models and ultimately obtaining site closure. Until recently, this exposure pathway was not often considered during site characterization. The direct measurement of the vapor intrusion to indoor ...

  • Effect of prenatal exposure to fine particles and postnatal indoor air quality on the occurrence of respiratory symptoms in the first two years of life

    The purpose of this study was to assess an impact of prenatal exposure to fine particles (PM2.5) on the risk of developing respiratory symptoms in early childhood. The study was carried out in a cohort of 465 newborns in Krakow (Poland) who have been followed over the first two years of life. The children exposed to medium level of PM2.5 (>35.3?53.4 µg/m³) had 13% more wheezing days (IRR = 1.13; ...

  • Biomonitoring of indoor air genotoxic properties in ten schools using Scindapsus aureus

    School is the most important indoor environment for children besides their home. Indoor air quality in school is a critical parameter that needs to be considered for children's health. Atmospheric measurements provide concentrations of pollutants which are used for risk assessments. However, those data are limited to study complex interactions between pollutants, and the genotoxic potential of ...

  • Mold Remediation Guidance For Indoor Environment

    Remediation contractors are generally very conscientious, trying hard to bring each project to a condition where it will pass “clearance  testing” (the  Post-Remediation  Verification  [PRV] inspection) on the first try. Sometimes the cleaning attempts are unsuccessful. This will certainly cost the contractor additional cleaning ...

  • Minimising Risks to Air Quality and Regulatory Compliance With Total Filter Management

    It has been shown in recent studies that as much as 25% of the total site operating budget (excluding raw material costs) for a typical medium-large dosage-form manufacturing facility will be spent on compliance measures for internal quality systems and external regulatory activities. (1) Market realities indicate that the pharmaceutical companies will need to address the overall cost of ...

  • Comparative Risk Assessment

    ' Comparative risk assessment provides a systematic way to compare environmental problems that pose different types and degrees of health risk. It combines information on the inherent hazards of pollutants, exposure levels and population characteristics to predict the resulting health effects. Using data from available sources, rapid, inexpensive comparative risk assessments can identify the most ...

  • Warehouse Optimization: Balancing Equipment Performance and Worker Safety Through Emissions Measurements and Air Quality Monitoring

    Successful warehouse functionality is dependent on both maximizing equipment performance and providing a safe and healthy environment for workers that encourages productivity. However, these two factors are often at odds with each other as warehouse equipment such as forklifts, burnishers and delivery trucks emit toxic gases that can have the potential to create poor indoor air quality which ...

  • Air uality in IVF Labs

    Since the birth of the first baby from in-vitro fertilisation (IVF) in 1978, Assisted Reproductive Technology (ART) has grown in importance as techniques and success rates have continued to improve. Put simply, IVF involves mixing sperm and egg in a lab to create an embryo which is then replaced in a woman's womb to develop normally with success being measured in terms ...
