Invisible work, unseen hazards: the health of women immigrant household service workers in Spain

Backgroud: Household service work has been largely absent from occupational health studies. We examine the occupational hazards and health effects identified by immigrant women household service workers. Methods: Exploratory, descriptive study of 46 documented and undocumented immigrant women in household services in Spain, using a phenomenological approach. Data were collected between September 2006 and May 2007 through focus groups and semi-structured individual interviews. Data were separated for analysis by documentation status and sorted using a mixed-generation process. In a second phase of analysis, data on psychosocial hazards were organized using the Copenhagen Psychosocial Questionnaire as a guide. Results: Informants reported a number of environmental, ergonomic and psychosocial hazards and corresponding health effects. Psychosocial hazards were especially strongly present in data. Data on reported hazards were similar by documentation status and varied by several emerging categories: whether participants were primarily cleaners or carers and whether they lived in or outside of the homes of their employers. Documentation status was relevant in terms of empowerment and bargaining, but did not appear to influence work tasks or exposure to hazards directly. Conclusions:Female immigrant household service workers are exposed to a variety of health hazards that could be acted upon by improved legislation, enforcement, and preventive workplace measures, which are discussed.

Neural correlates of evaluating hazards of high risk.

In personal and in society related context, people often evaluate the risk of environmental and technological hazards. Previous research addressing neuroscience of risk evaluation assessed particularly the direct personal risk of presented stimuli, which may have comprised for instance aspects of fear. Further, risk evaluation primarily was compared to tasks of other cognitive domains serving as control conditions, thus revealing general risk related brain activity, but not such specifically associated with estimating a higher level of risk. We here investigated the neural basis on which lay-persons individually evaluated the risk of different potential hazards for the society. Twenty healthy subjects underwent functional magnetic resonance imaging while evaluating the risk of fifty more or less risky conditions presented as written terms. Brain activations during the individual estimations of 'high' against 'low' risk, and of negative versus neutral and positive emotional valences were analyzed. Estimating hazards to be of high risk was associated with activation in medial thalamus, anterior insula, caudate nucleus, cingulate cortex and further prefrontal and temporo-occipital areas. These areas were not involved according to an analysis of the emotion ratings. In conclusion, we emphasize a contribution of the mentioned brain areas involved to signal high risk, here not primarily associated with the emotional valence of the risk items. These areas have earlier been reported to be associated with, beside emotional, viscerosensitive and implicit processing. This leads to assumptions of an intuitive contribution, or a "gut-feeling", not necessarily dependent of the subjective emotional valence, when estimating a high risk of environmental hazards.

Assessing perceptions of environmental risk and environmental justice and their impacts on neighborhood attachment in a predominately Hispanic community

This study examines and relates concepts from environmental risk perception and environmental justice and focuses on the perception of environmental problems, their consequent health risks and their impact on neighborhood attachment in a predominately Hispanic community along the U.S.-Mexico border. The findings indicate that the perception of environmental problems in the immediate area varies by problem and demographic subgroup. Ethnicity and income have the highest number of statistically significant associations across ten environmental problems. This result lies in the fact that Hispanics in El Paso County and those with low annual incomes live in neighborhoods that are faced with more severe environmental problems. Thus the findings lend support to the environmental justice claim that the poor and minorities bear the brunt of environmental degradation. ^ The findings also provide evidence that public perception of health risks from an environmental problem is influenced by the perceived severity of an environmental problem in the immediate area. Those who believe the problem is serious on a local level are the ones who are most likely to believe that they could become ill or injured from that problem and that the illness/injury will be serious. ^ The findings of this study also indicate that the young, Hispanics, those who perceive considerable environmental problems in their neighborhood, those who believe that their neighborhood has more environmental problems than others, and those who are angry about those problems are most likely to want to move from their neighborhood. ^ Efforts need to be made to enact policies and programs designed to reduce the environmental hazards in disadvantaged Hispanic communities along the U.S.-Mexico border. Future environmental education campaigns need to complement community-based projects with the media. Programs that involve and empower the community, particularly the youth, in improving the neighborhood could provide a sense of control and pride within their community in solving these problems. These neighborhood improvement efforts could also lead to the development and strengthening of social ties within the community, as well as enhanced community cohesiveness in tackling these problems. ^

Socio-economic distribution of environmental risk factors for childhood injury

Objective: Childhood injury remains the single most important cause of mortality in children aged between 1-14 years in many countries. It has been proposed that lower socio-economic status (SES) and poorer housing contribute to potential hazards in the home environment. This study sought to establish whether the prevalence of observed hazards in and around the home was differentially distributed by SES, in order to identify opportunities for injury prevention. Methods: This study was a cross-sectional, random sample survey of primary school children from 32 schools in Brisbane. Interviews and house audits were conducted between July 2000 and April 2003 to collect information on SES (income, employment and education) and previously identified household hazards. Results: There was evidence of a relationship between prevalence of household environmental hazards and household SES; however, the magnitude and direction of this relationship appeared to be hazard-specific. Household income was related to play equipment characteristics, with higher SES groups being more likely to be exposed to risk. All three SES indicators were associated with differences in the home safety characteristics, with the lower SES groups more likely to be exposed to risk. Conclusion:The differential distribution of environmental risk factors by SES of household may help explain the SES differential in the burden of injury and provides opportunities for focusing efforts to address the problem.

Reducing coronary heart disease in the Australian Coalfields: evaluation of a 10-year community intervention

Coronary heart disease is a leading cause of death in Australia with the Coalfields district of New South Wales having one of the country's highest rates. Identification of the Coalfields epidemic in the 1970's led to the formation of a community awareness program in the late 1980's (the healthy heart support group) followed by a more intense community action program in 1990, the Coalfields Healthy Heartbeat (CHHB). CHHB is a coalition of community members, local government officers, health workers and University researchers. We evaluate the CHHB program, examining both the nature and sustainability of heart health activities undertaken, as well as trends in risk factor levels and rates of coronary events in the Coalfields in comparison with nearby local government areas. Process data reveal difficulties mobilising the community as a whole; activities had to be selected for interested subgroups such as families of heart disease patients, school children, retired people and women concerned with family nutrition and body maintenance. Outcome data show a significantly larger reduction in case fatality for Coalfields men (although nonfatal heart attacks did not decline) while changes in risk factors levels were comparable with surrounding areas. We explain positive responses to the CHHB by schools, heart attack survivors and women interested in body maintenance in terms of the meaning these subgroups find in health promotion discourses based on their embodied experiences. When faced with a threat to one's identity, health discourse suddenly becomes meaningful along with the regimens for health improvement. General public disinterest in heart health promotion is examined in the context of historical patterns of outsiders criticising the lifestyle of miners, an orientation toward communal lather than individual responsibility for health (i.e, community 'owned' emergency services and hospitals) and anger about risks from environmental hazards imposed by industrialists.

Avaliação de geossintéticos na construção de aterros sanitários – caso de estudo: aterro do Giestal

Os aterros de resíduos contemplam, na sua constituição, uma série de sistemas e infraestruturas complementares que asseguram o correto funcionamento do mesmo, minimizando os perigos ambientais. A produção de lixiviados no interior das células de confinamento deste tipo de aterro é um fato inevitável sendo necessário, dada a sua perigosidade, o dimensionamento de um sistema de contenção e drenagem que promova o seu escoamento para zonas de tratamento. O presente trabalho assentou em três vertentes principais: o aprofundamento dos conhecimentos e exposição dos mesmos, na temática relacionada com aterros de resíduos e com a aplicação de geossintéticos neste tipo de infraestrutura, o acompanhamento da construção do novo aterro de resíduos não perigosos da Suldouro, o Aterro do Giestal, que vem substituir o seu precedente, já em fase de selagem, o aterro de Sermonde e a elaboração de uma análise crítica à solução construtiva apresentada no projeto de execução deste aterro. Neste contexto, é efetuada uma pesquisa bibliográfica exaustiva e assente, essencialmente, na problemática da gestão de resíduos, na utilização de geossintéticos em aterros de resíduos e no seu projeto e construção. O acompanhamento da obra debruçou-se, essencialmente, sobre a execução do sistema de impermeabilização e de drenagem de lixiviados da célula de confinamento, dando enfâse aos materiais utilizados, nomeadamente os geossintéticos, ao dimensionamento efetuado e aos processos construtivos utilizados e à garantia da qualidade da sua execução. Dados os riscos ambientais associados a este tipo de infraestruturas, são, para além dos sistemas referidos, analisados os elementos do sistema de monitorização de águas subterrâneas, sendo aqui abordados os materiais e processos construtivos. Por fim, é proposta uma solução alternativa à prevista no projeto de execução dos sistema de impermeabilização e drenagem de lixiviados. A solução desenvolvida, é inovadora, de custo mais reduzido e com vantagens acrescidas relativamente aos seus processos construtivos e à capacidade de armazenamento.

On the safe of pesticides in controlling the terrestrial mollusc pests

The preferred food items of the slugs Laevicaulis alte and the snails Achatina fulica were used to prepare 'poison baits'by injecting the pesticides 'Rogor'and 'Nuvan'to kill these mollusc pests. The 'poison baits'prepared with Thrichosanthes dioica and Lycopersicum esculentum were accepted by 100% individuals of both the species irrespective of the pesticides used. In all cases the slug and the snail individuals died within a considerable length of time following consuption of the bait. The importance of using 'poison bait'lies not only with the sure success in killing the pests but also with the 'safe use'of toxic materials in order to avoid environmental hazards.

Human mercury exposure associated with small-scale gold mining in Burkina Faso.

PURPOSE: In Burkina Faso, gold ore is one of the main sources of income for an important part of the active population. Artisan gold miners use mercury in the extraction, a toxic metal whose human health risks are well known. The aim of the present study was to assess mercury exposure as well as to understand the exposure determinants of gold miners in Burkinabe small-scale mines.METHODS: The examined gold miners' population on the different selected gold mining sites was composed by persons who were directly and indirectly related to gold mining activities. But measurement of urinary mercury was performed on workers most susceptible to be exposed to mercury. Thus, occupational exposure to mercury was evaluated among ninety-three workers belonging to eight different gold mining sites spread in six regions of Burkina Faso. Among others, work-related exposure determinants were taken into account for each person during urine sampling as for example amalgamating or heating mercury. All participants were medically examined by a local medical team in order to identify possible symptoms related to the toxic effect of mercury.RESULTS: Mercury levels were high, showing that 69% of the measurements exceeded the ACGIH (American Conference of Industrial Hygienists) biological exposure indice (BEI) of 35 µg per g of creatinine (µg/g-Cr) (prior to shift) while 16% even exceeded 350 µg/g-Cr. Basically, unspecific but also specific symptoms related to mercury toxicity could be underlined among the persons who were directly related to gold mining activities. Only one-third among the studied subpopulation reported about less than three symptoms possibly associated to mercury exposure and nearly half of them suffered from at least five of these symptoms. Ore washers were more involved in the direct handling of mercury while gold dealers in the final gold recovery activities. These differences may explain the overexposure observed in gold dealers and indicate that the refining process is the major source of exposure.CONCLUSIONS: This study attests that mercury exposure still is an issue of concern. North-South collaborations should encourage knowledge exchange between developing and developed countries, for a cleaner artisanal gold mining process and thus for reducing human health and environmental hazards due to mercury use.
