  • After creating toxic hazardous chemicals, society has followed an unsustainable course in using and disposing of toxins. More and more sites are being contaminated, cancer rates are rising, indoor air quality has declined to become often more contaminated than outdoor air, and toxic chemicals continue to be found in species as far away from civilization as the Arctic Circle. This chapter provides knowledge of hazardous chemicals: pollution and preventi.

  • It is hard to imagine that less than fifteen years ago building and fire codes specific to the construction of a wafer fabrication facility were just in the process of being developed. Detection and evaluation of leaking underground storage tanks and epidemiological health studies aimed at qualifying and quantifying our “cleanroom” image were in their infancy stages and Cal- OSHA had just completed the first in-depth study of the industry’s chemical processes and associated industrial hygiene exposures....

  • Within the overall transport process, attenuation processes may cause movement of the chemical to differ from that of the bulk flowing groundwater, for example dispersion, sorption and chemical or biological degradation of the chemical. Such attenuation processes potentially act to mitigate the impact of chemicals and are a function of both the specific chemical and geologic domain. Indeed, attenuation may vary significantly between individual chemicals and within different geological settings.

  • THERE IS probably no single course in “laboratory safety or chemical safety” at your college or university. Why not? Chemistry curricula have developed over many decades with a focus on the main topics of chemistry: organic, inorganic, physical chemistry, analytical chemistry, and (more recently) biochemistry. For decades, the topic of chemical safety was included at the margins of lab courses, mostly taught in a small way as a footnote to various lab experiments and procedures. Some chemists and chemistry teachers were aware of the importance of safety, while many were not.
