The present study explored the impact of mindfulness training on the relationship between false perceptions (hallucinations) and high levels of unusual experiences. 130 participants completed the O-LIFE(B) scale and a visual-detection task in which they had to identify fast-moving words in a visual display. Each participant completed a version of the visual-detection task twice, once after a 10 min mindfulness induction session, and once after a 10 min unfocused attention control session. Participants scoring high on the unusual experiences subscale of the O-LIFE reported seeing more words that were not there than those scoring low on this scale. However, this difference between high and low unusual experience scorers was not pronounced or statistically significant in the mindfulness condition. These data suggest that mindfulness can reduce the number of hallucination-like experiences in individuals with high levels of self-reported schizotypy.

Human exposure to lead may induce a variety of adverse effects on health including haematological, neurobehavioural, cardiovascular and renal changes and therefore continues to be a public health concern (Needleman 1989). Lead is dispersed in the environment from where it may be inhaled or ingested by man. Environmental exposure may arise from a number of potential sources: typically industrial emissions, exhaust from petrol engines, drinking water, foodstuffs, paint, soldered cans, lead glazed earthenware, dust and soil. A further source is tobacco smoke.
