... Chemical protective clothing (CPC) must possess certain physical properties if it is to function as an effective barrier to chemicals. The physical characteristics of CPC materials has gone largely unstudied; most attention has been focussed on chemical resistance. Physical property tests have...

... their jurisdictions. The Right-To-Know Law in New York State has successfully implemented a program which guarantees employees information on all chemicals for which data exist [as listed in the Registry of Toxic Effects of Chemical Substances (RTECS)], yet has a minimal employer impact. The law is comprehensive...

... An overall risk/benefit analysis relative to the use of chemical protective clothing for protection from potentially harmful chemicals must ultimately consider the barrier effectiveness of the skin to the chemicals in question. For example, there may be cases in which some permeation of chemical...

... A test method is proposed whereby effects of chemicals on reproduction of starlings ( Sturnus vulgaris ) are monitored in outdoor pen facilities throughout a breeding season. The method involves the use of replications of ten pairs of breeding starlings held in 3 by 3 by 7-m enclosures...

... Pesticide, food, drug, and cosmetic industries have used indicator animal species for many years to provide data on the relative hazards of synthetic or natural chemical products to applicators or users. A considerable amount of toxicological information is available on the relative...

... A survey was made of the types of waters, chemicals, and water treatment methods used in enhanced oil recovery operations. The study indicated that numerous types of waters, chemicals, and water treatment methods are used. Chemical and biochemical reactions can occur when different types...

... to be: ( a ) the chemical does not exhibit significant cumulative toxicity; ( b ) there is a single mode of action through which the effect of the chemical is manifested in a relatively short time frame; and ( c ) the effect is most severe on the critical life stages (that is, embryos and newly hatched fry), where...
