We identified 24 developmentally toxic DBPs and four adverse developmental outcomes associated with human DBP exposures: spontaneous abortion, cardiovascular defects, neural tube defects, and low birth weight infancy. (cyber-nook.com)
Even though cardiovascular diseases (CVDs) are the main of cause of the global burden of diseases attributable to PM exposure, it remains difficult to show reliable associations between exposure to wildland fire smoke and cardiovascular disease risk in population-based studies. (frontiersin.org)
Quantitative3
Validation of RLs and their exposure control effectiveness is collected in a traditional quantitative collection regime for regulatory auditing. (cdc.gov)
The Federal Register notice explains that EPA has observed that most PMN, SNUN, and exemption notices do not contain all required information at the level of detail that EPA needs to perform refined, quantitative risk assessments. (americanbar.org)
In these instances, EPA uses conservative assumptions and default values in its quantitative risk assessments to ensure the assessment protects human health and the environment. (americanbar.org)
Routes4
The analysis summarized the demographic characteristics, caller location (e.g., health care facility or residence), exposure routes, clinical health effects, and outcomes. (cdc.gov)
Reported exposures were predominantly ingestions (93.2%), although 2.8% involved inhalation, and 4.0% involved other routes of exposure, including dermal. (cdc.gov)
Despite the high THM levels in some areas and the extensive exposure assessment, results suggest that residential trihalomethane exposure during pregnancy driven by inhalation and dermal contact routes is not associated with birth weight, small for gestational age, low birth weight or preterm delivery in Spain. (cyber-nook.com)
BACKGROUND: Evidence for an association between exposure during pregnancy to trihalomethanes (THMs) in drinking water and impaired fetal growth is still inconsistent and inconclusive, in particular, for various exposure routes. (cyber-nook.com)
Unintentional2
Therefore, world-wide and massive application of these compounds have increased the risk of unintentional exposure to non-targets including the human beings. (bvsalud.org)
Therefore, during the current pandemic milieu, unintentional exposure to OPs through several environmental sources could escalate cardiac maladies in patients with COVID-19. (bvsalud.org)
Outcomes3
Multiple data elements are recorded (e.g., reason for poisoning, patient age, substances, clinical effects, therapies, and medical outcomes), as determined by the providers managing the exposures at each poison center. (cdc.gov)
Although the results have been somewhat inconsistent, some epidemiological studies suggest associations may exist between DBP exposures and adverse developmental outcomes. (cyber-nook.com)
Exposure of human populations to smoke emitted by these fires increases, thereby contributing to airborne pollution through the emission of gas and particulate matter (PM). The adverse health outcomes associated with wildland fire exposure represent an important burden on the economies and health systems of societies. (frontiersin.org)
Characterize2
To characterize the frequency of phenibut-related exposures in the United States, data on human exposure calls to U.S. poison centers during January 2009-December 2019 were extracted from the national database maintained by the American Association of Poison Control Centers. (cdc.gov)

These data are discussed in terms of three exposure periods: acute (14 days or less), intermediate (15-364 days), and chronic (365 days or more). (cdc.gov)
Other types of respiratory diseases potentially impacted by workplace exposures include chronic obstructive pulmonary disease (or COPD), hypersensitivity pneumonitis, silicosis, lung cancer, and bronchiolitis obliterans. (cdc.gov)
This method is useful for characterizing tobacco exposure that may be related to acute and chronic lung injury. (cdc.gov)
Epidemiological1
Supporting activities include the development of epidemiological, experimental laboratory, and risk-assessment methods that could produce internationally comparable results, and the development of manpower in the field of toxicology. (inchem.org)
Assessing3
Which methods for assessing exposure and health should be highlighted? (cdc.gov)
Assessing benzene exposure is a public health priority due to its deleterious health effects and ubiquitous industrial and environmental sources of exposure. (cdc.gov)
In this study, we present urinary 6-hydroxy-2,4-cyclohexadienyl mercapturic acid (pre-PhMA), a metabolite that undergoes acid-catalyzed dehydration to form PhMA, as a novel and specific urinary biomarker for assessing benzene exposure. (cdc.gov)
Risk7
However, qualitative risk assessment methods are also used within this validation process. (cdc.gov)
DOE has also developed and internal, adaptive risk assessment procedures and controls enforced standards published in the Code of Federal are developed6). (cdc.gov)

As a first step in a mixtures risk assessment for DBP developmental effects, this paper identifies developmentally toxic DBPs and examines data relevant to the mode of action (MOA) for DBP developmental toxicity. (cyber-nook.com)
Even with an emphasis on being more business friendly, programs will still have to process applications and complete risk assessments. (lawbc.com)
Re-work is the process of EPA redoing its risk assessment, for any number of reasons, including new information, corrections of misinterpretation of submitted information, and other reasons. (americanbar.org)
The agency calls the process of considering this new information and redoing the risk assessments "re-work. (americanbar.org)
Adverse2
The points in the figures showing no-observed-adverse-effect levels (NOAELs) or lowest- observed-adverse-effect levels (LOAELs) reflect the actual doses (levels of exposure) used in the studies. (cdc.gov)
Public health officials and others concerned with appropriate actions to take at hazardous waste sites may want information on levels of exposure associated with more subtle effects in humans or animals (LOAELs) or exposure levels below which no adverse effects (NOAELs) have been observed. (cdc.gov)

The site posed a public health hazard in the past to residents due to exposure to VOCs in their private wells. (cdc.gov)
Years1
Most exposures (58.4%) occurred among adults aged 18-34 years (mean = 31.7 years, standard deviation = 13.1 years, interquartile range = 22-38 years). (cdc.gov)
Effects5
In one half (49.6%) of cases, the exposure resulted in moderate effects (i.e., no long-term impairment). (cdc.gov)
Major effects (i.e., life-threatening or resulting in significant disability or disfigurement) occurred in one in eight (12.6%) reported exposures, and three deaths were reported. (cdc.gov)
Among exposures in which phenibut was the only drug or agent involved, 10.2% were associated with major effects, including one death. (cdc.gov)
