Adverse Effects of Methylmercury: Environmental Health Research Implications

BACKGROUND The scientific discoveries of health risks resulting from methylmercury exposure began in 1865 describing ataxia, dysarthria, constriction of visual fields, impaired hearing, and sensory disturbance as symptoms of fatal methylmercury poisoning. OBJECTIVE Our aim was to examine how knowledge and consensus on methylmercury toxicity have developed in order to identify problems of wide...

Introduction: Advances in Lead Research: Implications for Environmental Health

A method has been developed for measuring the drug sensitivity of human gliomas in short-term culture, using scintillation counting or autofluorography. Cell cultures prepared from malignant astrocytomas were treated with anticancer drugs whilst in exponential growth in microtitration plates. After drug treatment and a recovery period, residual viability was measured by [3H] leucine incorporati...

Environmental health research and regulation.

This symposium will present the results of our joint research effort. These reports will deal with the effects of both chemical and physical factors in the environment as they interact with organisms through a variety of pathways and produce a mul-tiplicity of biological effects. However diverse these studies appear to be, they all have one common objective: to produce experimental data which w...

Research by environmental health scientists.

RECENT studies of carcinoembryonic antigen (CEA) have demonstrated that the putatively pure preparations of CEA were not homogeneous. Rule and Goleski-Reilly (1973), by the isoelectric focusing of saline extracts of tumour materials, detected 6 major and 6 minor CEA reactive peaks between pH 2 0 and 9 0. Coligan et al. (1973) demonstrated by isoelectric focusing and ion exchange chromatographic...
