The trypanosomes could indeed be successfully killed with the dye trypan red. Beginning in 1906, he intensively investigated atoxyl and had it tested by Robert Koch along with other arsenic compounds during Koch's sleeping sickness expedition of 1906/07. Although the name literally means “nonpoisonous,” atoxyl does cause damage, especially to the optic nerve. Ehrlich elaborated the systematic testing of chemical compounds in the sense of screening as now practiced in the pharmaceutical industry.

The 3rd-4th-century writing implements from Mtskheta, Georgia. The original form of "lead pencil" was the leaden stylus used by the ancient Romans, who also used it to write on wood or papyrus by leaving dark streaks where the soft metal rubbed off onto the surface. The concept has been revived in recent times as the core of the "inkless pen": a lead-based metal alloy that leaves dark markings on paper by abrading small pieces of core onto the surface. However, most modern "lead pencils" have a nonpoisonous core of greyish-black graphite mixed with various proportions of clay for consistency, enclosed within an outer wooden casing to protect the fragile graphite from being snapped apart or from leaving marks on the user's hand.

Transportation of hazardous materials for commercial purposes in the USA is regulated by Code of Federal Regulations Title 49 - Transportation, (abbreviated 49 CFR). A cylinder containing 200 kPa (29.0 psig/43.8 psia) or greater at 20 °C (68 °F) of non-flammable, nonpoisonous compressed gas, and being transported for commercial purposes is classified as HAZMAT (hazardous materials) in terms of 49 CFR 173.115(b) (1). Cylinders manufactured to DOT standards or special permits (exemptions)issued by the Pipeline and Hazardous Materials Safety Administration and filled to the authorized working pressure are legal for commercial transport in the USA under the provisions and conditions of the regulations. Cylinders manufactured outside the USA may be transported under a special permit, and these have been issued for solid metal and composite cylinders with working pressures of up to 300 bar (4400 psi) by several manufacturers.
