Lead (Pb) and cadmium (Cd) are naturally occurring heavy metals
which have been redistributed to a large extent by man in the environment.
These metals have certain common toxic sites of action on
biological systems of mammals. Simultaneous exposure to Pb and Cd
is highly probable due to common sources...
The entire human population is chronically exposed to various
contaminants, including lead and chlorinated hydrocarbon pesticides.
Studies were undertaken to assess the effects of chronic exposure to
lead on the toxicities of two such pesticides, lindane and dieldrin.
Mice were given lead as the acetate in drinking water, at levels...

In the United States, lead poisoning is one of the most common
childhood diseases, and children of color are disproportionately its
victims. Portland is no different.
Despite federal restrictions on lead use, many low income and children
of color in Portland continue to live, learn and play in lead
The pyrrolizidine alkaloids (PAs) and ergot alkaloids are known natural
toxicants found in livestock forage. These alkaloids contribute to large
economic losses in livestock throughout the world. An understanding of the
mechanisms of toxicity and development of better diagnostic tools for better
management practices was investigated.
Variability exists in the...
The purpose of this research was to analyze the available pesticide poisoning data in Oregon from 1994 to 1998 in order to obtain a descriptive account of general incident information and of occupational exposures. These data were to be used by the Pesticide Analytical and Response Center for planning preventive...
The primary objective of this study was to assess radiator repair shops' compliance with Oregon OSHA Lead and Hazard Communication regulations. Fifty radiator repair shops were randomly selected from nine counties that comprise the highest population density in Oregon. All 50 worksites were visited; of these 50 worksites, 22 were...
Environmental contamination along roadways with lead from processed
petroleum and automotive residues has been reported. Toxicity to the herbivores grazing these areas has not been well studied. Comparison of lead concentrations adjacent to roads in Kuwait and in Oregon, USA was studied. Soil samples were taken from three sites at...
Childhood lead poisoning is one of the most common preventable pediatric health problems in the United States. Fetuses, neonates, and young children are particularly sensitive to adverse health effects associated with lead exposure due to children's hand to mouth activities, their greater ability to absorb lead, and their vulnerable developing...
