Two new studies highlight concerns about what some workers are inhaling on the job. An international study published in the Lancet (free registration required to view summary) found that occupational exposures account for a substantial portion of adults’ new-onset asthma, and that nurses have a significant excess risk of asthma. An Australian study published in Environmental Science & Technology found that several common models of office laser printers release amounts of ultra-fine particle pollution comparable to those from secondhand tobacco smoke.
