The Mineral Potential Project currently being undertaken in British Columbia requires estimation d unknown mineral resources. The method of resource assessment known as the BC Mineral Resource Assessment Process [19931. is described by Kilby (1995, this volume) and in Grunsky et al. (1.994). The method is based on the three-part ssessment methodology developed by the United States Geologica...

But light pollution is now ruining things for stargazers who stayed at home, concludes a report issued this week by the House of Commons Science and Technology Committee. It warns that the growing glow will soon blind a thriving corps of amateur astronomers and urges the government t...

Four chelating agents that have been used most commonly for the treatment of humans intoxicated with lead, mercury, arsenic or other heavy metals and metalloids are reviewed as to their advantages, disadvantages, metabolism and specificity. Of these, CaNa2EDTA and dimercaprol (British anti-lewisite, BAL) are becoming outmoded and can be expected to be replaced by meso-2,3-dimercaptosuccinic aci...

BACKGROUND The purpose of this study was to investigate the impact of a 20-year process of de-industrialization in the British Columbia (BC) sawmill industry on labour force trajectories, unemployment history, and physical and psychosocial work conditions as these are important determinants of health in workforces. METHODS The study is based on a sample of 1,885 respondents all of whom were s...

The sensitivity of the Enhanced Tuberculosis Surveillance (ETS) scheme for monitoring tuberculosis in children is unknown. We used the British Paediatric Surveillance Unit (BPSU) reporting scheme to conduct a prospective observational study of tuberculosis in children aged <16 yrs in the UK. Reported cases were then matched with records from the ETS database. A total of 320 cases were reported ...

Inferences of past climatic conditions from a sedimentary record from Big Lake, British Columbia, Canada, over the past 5,500 years show strong millennial-scale patterns, which oscillate between periods of wet and drier climatic conditions. Higher frequency decadal- to centennial-scale fluctuations also occur within the dominant millennial-scale patterns. These changes in climatic conditions ar...

In this paper, we use data from the British Crime Survey (BCS) to examine the effect of illicit drug use on labour market outcomes. We find very little evidence to support any relationship between drug use, hard or soft, and occupational attainment. However, we find compelling evidence to suggest that drug use, particularly the use of opiates, cocaine and crack cocaine, is associated with an in...
