Hydrogeochemical studies for Al, F and Fe in waters supplying haemodialysis units in the Trent region, U.K.
Abstract Geographical and seasonal variations in the concentrations of Al, F and Fe in tap water supplying home haemodialysis units within the administrative area of the Trent Regional Health Authority, have been examined. Aluminium and fluoride were considered for their implications in bone disorders and iron for its competitive binding with aluminium to transferrin in […]

A host of roasted daffodils
Hunchback fish no longer get their batter coating at the Tangier Street fish and chip shop. The fruits of the Irish Sea, which crashes furiously on to Whitehaven’s beaches, no longer find their way into the hot and vinegar-soaked newspaper wrapping at the fish bar across the road from the windswept harbour of the Cumbrian […]

Deadly risks of lead-free petrol
New petrochemical plants intended to improve city environments by producing “lead-free” petrol have created another, more deadly, environmental hazard. Accidents at the plants could lead to lethal clouds of hydrofluoric acid (HF), putting “tens of thousands at peril”, according to the Washington-based Environmental Policy Institute. The new process for making unleaded petrol involves using HF […]

Experts Warn of Lethal Risk Posed by Acid in L.A. Refineries
An environmentalist and a research scientist told a legislative hearing Wednesday that use of acutely toxic hydrofluoric acid at Los Angeles-area oil refineries poses a potentially deadly threat to nearby residents. “Most of us live in blissful ignorance of the kind of hazards we are exposed to,” said Fred Millar of the Environmental Policy Institute, […]

Aluminium and fluoride in the water supply and their removal for haemodialysis.
Abstract Aluminium and fluoride in the water supply and their removal for haemodialysis have been investigated in the Trent Region, U.K., and wide variations noted. The efficiency of removal of these elements from the mains water supplying home haemodialysis units by different water treatment systems currently installed has been assessed and a follow-up study performed […]

A recent special report in the American Chemical Society’s weekly Chemical and Engineering News documents growing concern about the health risks of fluoridation. There is also continuing debate about the […]

Mobil Refinery Study Fails to Address Key Risk Issue
Torrance City Council members expressed surprise Tuesday that an $88,000 study on safety of the Mobil Oil refinery will not answer their key question: What is the risk of the plant continuing to use hydrofluoric acid — an acutely toxic chemical — in the refining process. “That was the most important aspect of the whole […]

Fluoridation safety must be assessed
When it comes to herbicides, preservatives and other chemicals, the public can be mighty choosy about what it allows in its food and drink. Except, that is, when it comes to putting fluorides in its drinking water. Half the American population and hundreds of millions more people around the world now quiescently accept the presence […]
