    In the last two-year review, the authors posed a question as to whether industrial hygiene analytical chemistry was a "mature" field (A1). They concluded that this was not the case. Our survey of the recent literature leads us to the same conclusion. Analytical chemistry research remains highly innovative and productive in the industrial hygiene fi ...

    Many exposures in the workplace that can result in occupational asthma can also cause a variety of dermatological problems. These include irritant contact dermatitis, allergic contact dermatitis (Type IV delayed hypersensitivity), and urticaria (Type I immunologic and nonimmunoIogic). Urticaria will be discussed here because of its more direct asso ...

    A new type of respirable dust sampler was developed and compared side-by-side to personal gravimetric samplers in the laboratory. The new sampler correlates filter back pressure with mass accumulation to provide mid-shift- and end-of-shift determinations of cumulative exposure. The sampler uses a small low flow rate pump to draw dust through a smal ...
