Under the influence? The construction of foetal alcohol syndrome in UK newspapers

Today, alongside many other proscriptions, women are expected to abstain or at least limit their alcohol consumption during pregnancy. This advice is reinforced through warning labels on bottles and cans of alcoholic drinks. In most (but not all) official policies, this is linked to a risk of Foetal Alcohol Syndrome (FAS) or one of its associated conditions. However, given that there is little medical evidence that low levels of alcohol consumption have an adverse impact on the foetus, we need to examine broader societal ideas to explain why this has now become a policy concern. This paper presents a quantitative and qualitative assessment of analysis of the media in this context. By analysing the frames over time, this paper will trace the emergence of concerns about alcohol consumption during pregnancy. It will argue that contemporary concerns about FAS are framed around a number of pre-existing discourses including alcohol consumption as a social problem, heightened concerns about children at risk and shifts in ideas about the responsibility of motherhood including during the pre-conception and pregnancy periods. Whilst the newspapers regularly carried critiques of the abstinence position now advocated, these challenges focused did little to refute current parenting cultures.

Ecological studies on:(a) the use of colonisation samplers in relation to biological surveillance of river water quality (b) the requirements of freshwater gastropoda

Some of the factors affecting colonisation of a colonisation sampler, the Standard Aufwuchs Unit (S. Auf. U.) were investigated, namely immersion period, whether anchored on the bottom or suspended, and the influence of riffles. It was concluded that a four-week immersion period was best. S. Auf. U. anchored on the bottom collected both more taxa and individuals than suspended ones. Fewer taxa but more individuals colonised S. Auf. U. in the potamon zone compared to the rhithron zone with a consequent reduction in the values of pollution indexes and diversity. It was concluded that a completely different scoring system was necessary for lowland rivers. Macroinvertebrates colonising S. Auf. U. in simulated streams, lowland rivers and the R. Churnet reflected water quality. A variety of pollution and diversity indexes were applied to results from lowland river sites. Instead of these, it was recommended that an abbreviated species - relative abundance list be used to summarise biological data for use in lowland river surveillance. An intensive study of gastropod populations was made in simulated streams. Lynnaea peregra increased in abundance whereas Potamopyrgas jenkinsi decreased with increasing sewage effluent concentration. No clear-cut differences in reproduction were observed. The presence/absence of eight gastropod taxa was compared with concentrations of various pollutants in lowland rivers. On the basis of all field work it appeared that ammonia, nitrite, copper and zinc were the toxicants most likely to be detrimental to gastropods and that P. jenkinsi and Theodoxus fluviatilis were the least tolerant taxa. 96h acute toxicity tests of P. jenkinsi using ammonia and copper were carried out in a flow-through system after a variety of static range finding tests. P. jenkinsi was intolerant to both toxicants compared to reports on other taxa and the results suggested that these toxicants would affect distribution of this species in the field.
