In vitro evaluation of cytotoxicity and oxidative stress induced by multiwalled carbon nanotubes in murine RAW 264.7 macrophages and human A549 lung cells.

Objective: To investigate in vitro cytotoxicity and oxidative stress response induced by multiwalled carbon nanotubes (MWCNTs).

Methods: Cultured macrophages (murine RAW264.7 cells) and alveolar epithelium cells type II (human A549 lung cells) were exposed to the blank control, DNA salt control, and the MWCNTs suspensions at 2.

[Exposure to 1-bromopropane causes dose-dependent neurological abnormalities in workers].

Objective: To explore the dose-effect relationship between 1-bromopropane (1-BP) exposure and health effects in workers.

Methods: Occupational field investigations were conducted in 1-BP factories. Ambient 1-BP concentrations were detected with detection tube, and the 8 h time-weighted average individual exposure levels (TWA-8 h) were measured by passive sampler.

[Effects of 1-bromopropane on neurological and hematological changes of female exposed workers].

Objective: To investigate the health effects of 1-bromopropane (1-BP) on female exposed workers.

Methods: Four 1-BP manufacturing plants were investigated. Workers were interviewed with questionnaire and examined with neurobehavioral core test battery, nerve conduction velocity tests of nervus tibialis and nervus suralis, vibration sensation test, hematological and biochemical tests.
