Toxic Substances Board

Unfortunately, this campaign does not address the issue of child resistant packaging for scheduled toxic substances. The Toxic Substances Board (an advisory committee to the Minister of Health) recommended that the Ministry adq)t their proposed draft legislation amending the Toxic Substances Regulations such that child resistant closures would be required for certain scheduled chemicals including pesticides with container capacities <2.5 1. Currently, this remains unactioned.

Formaldehyde and other aldehydes are receiving increasing attention both as toxic substances and as promoters in the photochemical formation of ozone in the atmosphere. They are released into residential buildings from plywood and particle board, insulation, combustion appliances, tobacco smoke, and various consumer products. Aldehydes are released into the atmosphere in the exhaust of motor vehicles and other equipment in which hydrocarbon fuels are incompletely burned. A sensitive method for analyzing aldehydes and ketones is based on the sorption of these compounds to an SPE sorbent and their subsequent reaction with 2,4-dinitrophenylhydrazine (DNPH) on the sorbent. They are then analyzed as their hydrazones by HPLC (Fig. 7.9). A gradient analysis by HPLC may separate as many as 17 components with detection by ultraviolet (UV) light.

In order to answer the question are there any more DBCP-type problems out there awaiting discovery, the State Board in May 1980 established a Toxic Substances Control Program. A major focus of this program was development of an "early warning" priority chemicals project to (1) assess risks, (2) recommend water quality objectives, and (3) propose appropriate mitigation measures for agricultural and industrial chemicals most likely to adversely impact surface or ground water quality. 

Comparative Dose Response Data There are only a limited number of cases in which it has been possible, even on a crude level, to compare animal and human dose responses to the same carcinogens. The paucity of data in this area is related to the fact that in most epidemiological studies the actual doses of the toxic substance is not known with certainty and that while complete dose response curves can be obtained in animal studies, such studies are very expensive. A systematic attempt to estimate human exposures and compare human and animal dose response relationships for several known carcinogens has been made and is contained in a report by the National Academy of Sciences and National Research Council on Environmental Studies Board on Pest Control.The carcinogens for which responses were compared in the study were benzidine chlornaphazine diethylstilbestrol aflatoxin Bl vinyl chloride, and cigarette smoke.

Sheila Pressley, DrPH, is an associate professor in the Department of Enviromnental Health Science at Eastern Kentucky University (EKU) in Richmond, Kentucky. Her research interests include children s environmental health issues as they relate to toxic substance exposures from lead and illegal drug lab enviromnents, as well as food safety and security. In addition to her book publications, she has also published articles in various newsletters, magazines, and journals. Pressley received a BS in environmental health science from Western Carolina University. She received an MS from the Civil Engineering School at Tufts University and a DrPH from the University of Kentucky s College of Public Health. She also holds a number of professional certifications, such as the Registered Environmental Health Specialist credential from the National Enviromnental Health Association and the Certified in Public Health credential from the National Board of Public Health Examiners.

The Ministry of Power publishes the reports of the Electricity Council, Gas Council, National Coal Board and special reports such as The Efficient Use of Fuel. The Ministry of Labour issues reports on factory inspection, industrial health, and the series of pamphlets on Choice of Careers. Much useful information is contained in the Safety Health and Welfare series such as No. 8, Toxic Substances in Factory Atmospheres. The Ministry of Agriculture, Fisheries and Food s Circulars are valuable and include items such as Chemical Compounds used in Agriculture and Food Storage.
