Accidental consumption of mercury by 3 year-old child - case report
Consumption of mercury can be accidental or on purpose. The article presents a case of a 3 yo child’s word patient after accidental consumption of mercury contained in the thermometer used to check the body temperature of body during infection.
The medical examination showed viral infection, routine laboratory diagnostic was carried out – without damaging internal organs and picture diagnostic which confirmed the presence of intensely saturated radiological shades which may correspond to mercury drops in digestive truck.
After 3 days of observation in children's ward, no signs of poisoning were found and the patient was sent home.
Despite the withdrawal from production and sale within the European Union, thermometers with mercury are still in widespread use because of lack of social awareness of the harmful effects of mercury on human body and the environment
Measuring the Value of Health Improvements from Great Lakes Cleanup
Exposure to pollutants in the Great Lakes Region can have significant effects on human health. Some forms of pollution affect humans directly, through the air we breathe and water we drink. Other forms of pollution affect humans indirectly, for example through consumption of contaminated fish. In this paper the authors describe methods to measure health benefits in monetary and nonmonetary terms in the context of reductions in pollutants as part of a program to improve the environment in the Great Lakes. The paper is meant to be an introduction to this topic for a general audience interested in the Great Lakes.

Leveraging Epidemiology to Improve Risk Assessment.
The field of environmental public health is at an important crossroad. Our current biomonitoring efforts document widespread exposure to a host of chemicals for which toxicity information is lacking. At the same time, advances in the fields of genomics, proteomics, metabolomics, genetics and epigenetics are yielding volumes of data at a rapid pace. Our ability to detect chemicals in biological and environmental media has far outpaced our ability to interpret their health relevance, and as a result, the environmental risk paradigm, in its current state, is antiquated and ill-equipped to make the best use of these new data. In light of new scientific developments and the pressing need to characterize the public health burdens of chemicals, it is imperative to reinvigorate the use of environmental epidemiology in chemical risk assessment. Two case studies of chemical assessments from the Environmental Protection Agency Integrated Risk Information System database are presented to illustrate opportunities where epidemiologic data could have been used in place of experimental animal data in dose-response assessment, or where different approaches, techniques, or studies could have been employed to better utilize existing epidemiologic evidence. Based on the case studies and what can be learned from recent scientific advances and improved approaches to utilizing human data for dose-response estimation, recommendations are provided for the disciplines of epidemiology and risk assessment for enhancing the role of epidemiologic data in hazard identification and dose-response assessment
Public health and landfill sites
Landfill management is a complex discipline, requiring very high levels of organisation, and considerable investment. Until the early 1990’s most Irish landfill sites were not managed to modern standards. Illegal landfill sites are,
of course, usually not managed at all. Landfills are very active. The traditional idea of ‘put it in the ground and forget about it’ is entirely misleading. There is a lot of chemical and biological activity underground. This produces complex changes in the chemistry of the landfill, and of the emissions from the site.
The main emissions of concern are landfill gases and contaminated water (which is known as leachate). Both of these emissions have complex and changing chemical compositions, and both depend critically on what has been
put into the landfill. The gases spread mainly through the atmosphere, but also through the soil, while the leachate (the water) spreads through surface waters and the local groundwater. Essentially all unmanaged landfills will discharge large volumes of leachate into the local groundwater. In sites where the waste accepted has been
properly regulated, and where no hazardous wastes are present, there is a lot known about the likely composition of this leachate and there is some knowledge of its likely biological and health effects. This is not the case for
poorly regulated sites, where the composition of the waste accepted is unknown.
It is possible to monitor the emissions from landfills, and to reduce some of the adverse health and environmental effects of these. These emissions, and hence the possible health effects, depend greatly on the content of the landfill, and on the details of the local geology and landscape.
There is insufficient evidence to demonstrate a clear link between cancers
and exposure to landfill, however, it is noted that there may be an association
with adverse birth outcomes such as low birth weight and birth defects. It
should be noted, however, that modern landfills, run in strict accordance with
standard operation procedures, would have much less impact on the health of
residents living in proximity to the site
Children\u27s Health in Latin America: The Influence of Environmental Exposures
Background:Chronic diseases are increasing among children in Latin America. Objective and Methods:To examine environmental risk factors for chronic disease in LatinAmerican children and to develop a strategic initiative for control of these exposures, the WorldHealth Organization (WHO) including the Pan American Health Organization (PAHO), the Collegium Ramazzini, and Latin American scientists reviewed regional and relevant global data. Findings: Industrial development and urbanization are proceeding rapidly in Latin America and environmental pollution has become widespread. Environmental threats to children\u27s health include traditional hazards such as indoor air pollution and drinking water contamination; as well as the newer hazards of urban air pollution; toxic chemicals such as lead, asbestos, mercury,arsenic, and pesticides;hazardous and electronic waste;and climate change. The mix of traditional and modern hazards varies greatly across and within countries reflecting industrialization, urbanization and socioeconomic forces. Conclusions: To control environmental threats to children\u27s health in Latin America, WHO, including PAHO will focus on the most highly prevalent and serious hazards - indoor and outdoor air pollution, water pollution, and toxic chemicals. Strategies for controlling these hazards include developing tracking data on regional trends in children\u27s environmental health(CEH); building a network of Collaborating Centres; promoting biomedical research in CEH;building regional capacity; supporting development of evidence-based prevention policies; studying the economic costs of chronic diseases in children; and developing platforms for dialogue with relevant stakeholders.
Reported Crimes and Misdeeds by Concealed Weapons License and Permit Holders
The gun lobby claims that only ìlaw-abiding citizensî have concealed weapons licenses or permits. From that assumption, the gun lobby argues that having more people carrying loaded, concealed firearms makes society "safer." Both claims are false.Studies by reputable academics who study this problem have discovered, "[T]he weight of the evidence is now firmly behind those who have found that right-to-carry laws do not reduce, and may even increase, the overall level of crime." The following incidents -- specific events described in our nation's newspapers -- involve crimes or misdeeds reportedly at the hands of people licensed to carry concealed weapons. It is important to note, however, that these incidents represent only a fraction of the total number of dangerous and deadly incidents involving concealed carry licensees. This is the case because a suspect's status as a concealed carry permit-holder is often not reported by law enforcement or the media, and also because such information is steadily becoming less available to the public due to gun lobby intimidation
Green criminology and the reconceptualization of school violence: Comparing green school violence and traditional forms of school violence for school children
School crime and violence continue to be important topics of criminological inquiry. Forms of violence that have received much attention from criminologists include school gun violence, assaults, and bullying. What appears missing from criminological studies are analyses of different forms of violent victimization imposed on school children related to environmental injustice, pollution, and exposure to toxins. In this article, we argue for the interpretation of these harms as violent victimizations. To facilitate this, we draw upon definitions of violent victimization developed in green criminology, conceptualizing exposure to environmental toxins as violent assault, and introduce the term green school violence (GSV). Next, we draw upon the medical, environmental, and public health literature to offer a series of examples of GSV in the United States, discuss numerous environmental hazards present in American schools, and describe their scope and severity. A conservative estimate of the frequency of GSV suggests that far more school children are victimized by GSV than forms of interpersonal acts of violence
Pathological changes in seals in Swedish waters: the relation to environmental pollution
This thesis concerns the disease situation for the three seal species that inhabit the Swedish coastal waters; the grey seal (Halichoerus grypus), the ringed seal (Phoca hispida botnica) and the harbour seal (Phoca vitulina). A severe decline of the populations of Baltic grey and ringed seals took place during the second half of the 1960s. It was suggested to be caused by the contamination by industrial chemicals, above all organochlorines such as PCB and DDT. High concentrations of these substances were found in the Baltic biota. The author has performed necropsy or examination of organ samples from animals, which were found dead on shore, by caught at fishery or killed by hunting during 1977-2002. Multiple chronic organ lesions were found most prominent in the female reproductive organs (uterine stenoses and occlusions), intestines (colonic ulcers) and adrenals (cortical hyperplasia). Severe lesions were present also in the skeleton, integument and kidneys. The character and distribution of the lesions was regular and the disease picture tentatively was named the Baltic Seal Disease Complex (BSDC). The changes in the female reproductive organs indicate that reproductive failure is an important factor behind the decline of the Baltic seal populations. Adrenocortical hyperplasia was a regular and striking component of the BSDC. It is a common feature of prolonged stress in animals and man. The animals in this study have suffered from severe inflammatory processes in connection with more or less advanced malnutrition due to hampered ingestion and digestion of food. This is in the author’s opinion the most probable explanation of the adrenal changes. Inflammatory changes were most prominent in the intestines with deep ulcerations, in several cases leading to perforation of the intestinal wall. Bacteriological investigation revealed opportunistic or pathogenic micro-organisms but a common bacterial aetiology could not be suggested. The severity and wide dispersion of the lesions are interpreted as signs of a defective immune response. Minor lesions in the ileocaeco-colonic region caused by hookworms are regarded as the primary event of the ulcerous processes facilitating the establishment of secondary bacterial infections. Harbour seals showed less developed pathological changes but instead were victims of two Distemper epizootics with high mortality (c60%), during 1988 and 2002. During the 14- year-period after 1988 the Swedish harbour seal population gradually attained to the preepizootic size; a fast recover compared with the situation in Baltic grey and ringed seal populations suffering from the BSDC problems. A decrease in the prevalence of the lesions of the BSDC has been demonstrated concurrent with a decreased contamination of the Baltic biota towards the end of the 1900s. This is a strong indication of the role of pollutants as the main factor behind the BSDC. Other factors may also be involved, however, as indicated by the observation that the prevalence of intestinal ulcers still is high in Baltic grey seals
