Effects noted from exposures of 2-2.5 hours at 1,000 ppm include impaired visual-motor coordination (measured by groove-type hand steadiness, depth perception, and pegboard tests) (Vernon and Ferguson 1969) and, at 200 ppm, an increase in heart and breathing rates when trichloroethylene was inhaled simultaneously with ethanol ingestion (Windemuller and Ettema 1978). This latter study found no effect without ethanol ingestion. An 8-hour exposure (two 4-hour exposures separated by 1.5 hours) to 110 ppm...

It appears that animals are affected at roughly the same blood lead levels as humans. Measured neurotoxic effects in animals include significantly delayed motor function and reflexes, decreased performance on learning tasks, and impaired spatial discrimination. Additional animal studies are needed to investigate the neurotoxic effects of subchronic inhalation exposures to establish external dose-effect relationships.

M [8]. Ferguson et al. [10] have shown that matrix effects may result in severe ion suppression in APEO analysis (this phenomenon occurs particularly in negative mode electrospray ionisation). They also demonstrated that the effect may be accounted for appropriately when using internal and surrogate standards, which closely mimic the ionisation behaviour of the analytes. In Ferguson s study, specially...

The published results concerning polymerization of acrylic acid or methacrylic acid in the presence of polyCethylene oxide) in water are controversial. Ferguson and Shah found that PEG with sufficiently high molecular weight increases the polymerization rate, while Kabanov at al found that in the presence of high molecular weight PEG the rate of polymerization of acrylic and methacrylic acids is lower than in blank reaction. Our results show that in the case of methacrylic acid photopolymerization in the presence of PEG of mol. weight 20,000, the rate of the reaction increases. This differences can be explained by the conditions of polymerization as well as methods used to follow the process different in both studies. 

Another technique which is used to follow the extent of template polymerization vs. time is turbidimetry. Two types of measurements can be used here. The first is based on the determination of passed light intensity, the second on the determination of scattered light intensity. The former was used in many papers by Ferguson and co-workers for studies on polymerization of acrylic acid in aqueous solution in the presence of many homopolymers used as templates as well as for application of copolymers with interacting and non-interacting groups. This measurement was also used for studying com-...
