First World Trade Center scientific and medical review released
NIOSH    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The CDC's National Institute for Occupational Safety and Health (NIOSH) issued the First Periodic Review of Scientific and Medical Evidence Related to Cancer for the World Trade Center (WTC) Health Program. This first periodic review provides a summary of the current scientific and medical findings in the peer-reviewed literature about exposures resulting from the Sept. 11, 2001, terrorist attacks in New York City and cancer studies.

Genotoxicity in vinyl chloride-exposed workers and its implication for occupational exposure limit
PubMed    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Vinyl chloride monomer (VCM) is a colorless gas under room temperature and has been mostly used to produce polyvinyl chloride (PVC) since the 1970s. It is classified by the International Agency of Research on Cancer (IARC) as a known human carcinogen (Group 1). In this study, genetic damage in VCM workers was evaluated in relation to their occupational cumulative exposure to VCM. More

Informing selection of nanomaterial concentrations for ToxCast in vitro testing based on occupational exposure potential
Environmental Health Perspectives    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Little justification is generally provided for selection of in vitro assay testing concentrations for engineered nanomaterials (ENMs). Selection of concentration levels for hazard evaluation based on real-world exposure scenarios is desirable. More

Does smoking have a significant impact on early irritant hand dermatitis in metal workers?
PubMed    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Although they know the long-term complications of smoking, many smokers require additional motivation for entering a smoking cessation program. At the same time, smoking is considered a possible promoting factor for various skin diseases. More

Occupational exposures to styrene vapor in a manufacturing plant for fiber-reinforced composite wind turbine blades
The Annals of Occupational Hygiene    Share    Share on FacebookTwitterShare on LinkedinE-mail
A utility-scale wind turbine blade manufacturing plant requested assistance from the National Institute for Occupational Safety and Health (NIOSH) in controlling worker exposures to styrene at a plant that produced 37 and 42 meter long fiber-reinforced wind turbine blades. The plant requested NIOSH assistance because previous air sampling conducted by the company indicated concerns about peak styrene concentrations when workers entered the confined space inside of the wind turbine blade. NIOSH researchers conducted two site visits and collected personal breathing zone and area air samples while workers performed the wind turbine blade manufacturing tasks of vacuum-assisted resin transfer molding (VARTM), gelcoating, glue wiping, and installing the safety platform.

Relevance of both individual risk factors and occupational exposure in cancer survival studies: The example of intestinal type sinonasal adenocarcinoma
PubMed    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Wood dust is a well-established risk factor for intestinal type sinonasal adenocarcinoma. The 5-year overall survival has varied from 20 percent to 80 percent according T1-T4 stages; 5-year survival according to histologic subtype has varied from 20 percent to 50 percent. To date, no study has evaluated whether environmental, occupational, and personal risk factors have any impact on both overall and cancer-specific survival. We aimed to determine whether exposure to carcinogenic risk factors besides wood exposure can influence the survival of patients with sinonasal ethmoid carcinoma. More

US Labor Department's MSHA releases mid-year mine fatality update
MSHA    Share    Share on FacebookTwitterShare on LinkedinE-mail
The U.S. Department of Labor's Mine Safety and Health Administration released a midyear summary of mining deaths in the country. As of June 30, eight miners were killed in coal mining operations, and six in the metal and nonmetal sector. More

Shift work and pregnancy outcomes: a systematic review with meta-analysis of currently available epidemiological studies
PubMed    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Varying work schedules are suspected of increasing risks to pregnant women and to fetal wellbeing. In particular, maternal hormonal disturbance arising from sleep deprivation or circadian rhythm disruption might impair fetal growth or lead to complications of pregnancy. Two independent meta-analyses (from 2000 to 2007) reported a small adverse effect of shift work on the risk of preterm delivery (PTD). However, these reviews were based on few high-quality studies.
