Adverse human health effects have been observed to correlate with levels of outdoor particulate matter (PM), even though most exposure PM origin occurs indoors. In this study, we apply a model and empirical data explore the indoor for two major building types: offices residences. Typical ventilation rates each type are obtained from literature. Published combined theoretical analyses develop representative particle penetration coefficients, deposition loss rates, ventilation-system filter...

Identifying air pollutants that pose a potential hazard indoors can facilitate exposure mitigation. In this study, we compiled summary results from 77 published studies reporting measurements of chemical in residences the United States and countries with similar lifestyles. These data were used to calculate representative mid-range upper-bound concentrations relevant chronic exposures for 267 peak acute five activity-associated pollutants. Representative are compared available health...
The human toxicity potential (HTP), a calculated index that reflects the harm of unit chemical released into environment, is based on both inherent compound and its dose. It used to weight emissions inventoried as part life-cycle assessment (LCA) or in toxics release inventory (TRI) aggregate terms reference compound. Total can be evaluated benzene equivalence (carcinogens) toluene equivalents (noncarcinogens). dose using generic fate exposure model, CalTOX, which determines distribution...

Little information has been published about pesticide exposures experienced by pregnant women. We measured six dialkyl phosphate (DAP) urinary metabolites of organophosphate (OP) pesticides in 600 pregnant, low-income women living the Salinas Valley, California, an agricultural area. A total 28% were employed as farm fieldworkers during pregnancy, and 81% had at least one household member who worked agriculture. Samples collected twice pregnancy (mean = 13 26 weeks' gestation, respectively)...
Biofuels are widely touted as viable, albeit not straightforward, alternatives to petroleum-derived fuels. To best determine their utilization, many practitioners turn life-cycle assessment (LCA) ascertain the "environmental footprint". Although parameters such resource and land use, along with infrastructure, can be incorporated into LCA algorithms, have noted that methodological approach still needs careful attention. In this Feature, McKone et al. outline seven grand challenges need...
Global climate change (GCC) is likely to alter the degree of human exposure pollutants and response populations these exposures, meaning that risks could in future. The present study, therefore, explores how GCC might affect different steps pathway from a chemical source environment through impacts on health evaluates implications for existing risk-assessment management practices. In certain parts world, predicted increase level many environmental due direct indirect effects use patterns...
Approximately 13 million U.S. children less than 6 years old spend some time in early childhood education (ECE) facilities where they may be exposed to potentially harmful chemicals during critical periods of development. We measured five phthalate esters indoor dust (n = 39) and outdoor air 40 14, respectively) at ECE Northern California. Dust airborne concentrations were used perform a probabilistic health risk assessment compare estimated exposures with levels established for causing...
Studies report that residential use of pesticides in low-income homes is common because poor housing conditions and pest infestations; however, exposure data on contemporary-use households limited. We conducted a study from urban agricultural communities to: characterize compare house dust levels residential-use pesticides; evaluate the correlation pesticide concentrations samples collected several days apart; examine whether phased-out for uses, but still used agriculture (i.e.,...
We measured 34 metabolites of current-use pesticides and other precursor compounds in urine samples collected twice during pregnancy from 538 women living the Salinas Valley California, a highly agricultural area (1999-2001). Precursors these included fungicides, carbamate, organochlorine, organophosphorus (OP), pyrethroid insecticides, triazine chloroacetanilide herbicides. also ethylenethiourea, metabolite ethylene-bisdithiocarbamate fungicides. Repeat measurements presented here have not...
In the modern global economy, water and energy are fundamentally connected. Water already plays a major role in electricity generation and, with biofuels poised to gain significant share of transportation fuel market, will become significantly more important for as well. This research provides insight into potential changes use resulting from increased biofuel or production energy, well greenhouse gas freshwater implications. It is shown that when characterizing impact incorporating indirect...
Reducing chemical pressure on human and environmental health is an integral part of the global sustainability agenda. Guidelines for deriving globally applicable, life cycle based indicators are required to consistently quantify toxicity impacts from emissions as well chemicals in consumer products. In response, we elaborate methodological framework present recommendations advancing near-field/far-field exposure characterization, implementing these scientific consensus model USEtox.An expert...
