Water contamination in North Cornwall: a retrospective cohort study into the acute and short-term effects of the aluminum sulphate incident in July 1988

Abstract

IN JULY 1988 the drinking water supply of part of Cornwall was contaminated with 20 tons of aluminum sulphate solution. Emergency measures ensured that aluminum sulphate levels in most parts of the water distribution system were rapidly reduced, but residents were supplied with water containing raised concentrations of aluminum and other metals for at least a few days. A retrospective cohort study compared 480 individuals in the exposed area with 532 individuals resident in an area served by a different water supply. The exposed group were more likely to complain of all 18 symptoms in the questionnaire enquiry. They had a significantly higher relative risk of experiencing painful joints. These symptoms were reported by less than a quarter of the respondents exposed to contaminated water. This may represent a previously unrecognised acute effect of water contamination with aluminum sulphate, but the study does not exclude the possibility that the threshold for symptom reporting was lowered by anxiety and by the publicity associated with the incident. The overall response rate of the study was low (45%) and reflects the difficulties in both carrying out and interpreting environmental epidemiological studies of acute incidents.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
