Action Against Hunger is a global humanitarian organization which originated in France and is committed to ending world hunger. The organization helps malnourished children and provides communities with access to safe water and sustainable solutions to hunger.
Lead is a chemical element; it has symbol Pb and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements.
Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity). Sometimes the word is more or less synonymous with poisoning in everyday usage.
Lead poisoning, also known as plumbism and saturnism, is a type of metal poisoning caused by lead in the body. Symptoms may include abdominal pain, constipation, headaches, irritability, memory problems, infertility, and tingling in the hands and feet. It causes almost 10% of intellectual disability of otherwise unknown cause and can result in behavioral problems. Some of the effects are permanent. In severe cases, anemia, seizures, coma, or death may occur.
White spirit (AU, UK and Ireland) or mineral spirits (US, Canada), also known as mineral turpentine (AU/NZ/ZA), turpentine substitute, and petroleum spirits, is a petroleum-derived clear liquid used as a common organic solvent in painting. There are also terms for specific kinds of white spirit, including Stoddard solvent and solvent naphtha (petroleum). White spirit is often used as a paint thinner, or as a component thereof, though paint thinner is a broader category of solvent. Odorless mineral spirits (OMS) have been refined to remove the more toxic aromatic compounds, and are recommended for applications such as oil painting.
Cadmium is a naturally occurring toxic metal with common exposure in industrial workplaces, plant soils, and from smoking. Due to its low permissible exposure in humans, overexposure may occur even in situations where only trace quantities of cadmium are found. Cadmium is used extensively in electroplating, although the nature of the operation does not generally lead to overexposure. Cadmium is also found in some industrial paints and may represent a hazard when sprayed. Operations involving removal of cadmium paints by scraping or blasting may pose a significant hazard. The primary use of cadmium is in the manufacturing of NiCd rechargeable batteries. The primary source for cadmium is as a byproduct of refining zinc metal. Exposures to cadmium are addressed in specific standards for the general industry, shipyard employment, the construction industry, and the agricultural industry.
The Radium Girls were female factory workers who contracted radiation poisoning from painting radium dials – watch dials and hands with self-luminous paint. The incidents occurred at three factories in the United States: one in Orange, New Jersey, beginning around 1917; one in Ottawa, Illinois, beginning in the early 1920s; and one in Waterbury, Connecticut, also in the 1920s.
Lead paint or lead-based paint is paint containing lead. As pigment, lead(II) chromate, lead(II,IV) oxide,, and lead(II) carbonate are the most common forms. Lead is added to paint to accelerate drying, increase durability, maintain a fresh appearance, and resist moisture that causes corrosion. It is one of the main health and environmental hazards associated with paint. Lead paint has been generally phased out of use due to the toxic nature of lead. Alternatives such as water-based, lead-free traffic paint are readily available.
Blood lead level (BLL), is a measure of the amount of lead in the blood. Lead is a toxic heavy metal and can cause neurological damage, especially among children, at any detectable level. High lead levels cause decreased vitamin D and haemoglobin synthesis as well as anemia, acute central nervous system disorders, and possibly death.
The United States established diplomatic relations with Malawi in 1964 after Malawi gained independence from the United Kingdom. Malawi's transition from a one-party state to a multi-party democracy significantly strengthened the already cordial U.S. relationship with Malawi. Significant numbers of Malawians study in the United States. The United States has an active Peace Corps program, Centers for Disease Control and Prevention, Department of Health and Human Services, and an Agency for International Development (USAID) mission in Malawi. Both countries have a common history and English language, as they were part of the British Empire.
HIV and AIDS is a major public health issue in Zimbabwe. The country is reported to hold one of the largest recorded numbers of cases in Sub-Saharan Africa. According to reports, the virus has been present in the country since roughly 40 years ago. However, evidence suggests that the spread of the virus may have occurred earlier. In recent years, the government has agreed to take action and implement treatment target strategies in order to address the prevalence of cases in the epidemic. Notable progress has been made as increasingly more individuals are being made aware of their HIV/AIDS status, receiving treatment, and reporting high rates of viral suppression. As a result of this, country progress reports show that the epidemic is on the decline and is beginning to reach a plateau. International organizations and the national government have connected this impact to the result of increased condom usage in the population, a reduced number of sexual partners, as well as an increased knowledge and support system through successful implementation of treatment strategies by the government. Vulnerable populations disproportionately impacted by HIV/AIDS in Zimbabwe include women and children, sex workers, and the LGBTQ+ population.
Lead-based paint was widely used in the United States because of its durability. The United States banned the manufacture of lead-based house paint in 1978 due to health concerns.
The environmental impact of paint can vary depending on the type of paint used and mitigation measures. Traditional painting materials and processes can have harmful effects on the environment, including those from the use of lead and other additives. Measures can be taken to reduce its environmental effects, including accurately estimating paint quantities so waste is minimized, and use of environmentally preferred paints, coating, painting accessories, and techniques.
Most lead-based paint in the United Kingdom were banned from sale to the general public in 1992, except for specialist uses. Prior to this, lead compounds had been used as the pigment and drying agent in different types of paint, for example brick and some tile paints. Lead-based paint has been an important cause of lead poisoning.
The Johns Hopkins Center for Communication Programs (CCP) was founded over 30 years ago by Phyllis Tilson Piotrow as a part the Johns Hopkins Bloomberg School of Public Health's department of Health, Behavior, and Society and is located in Baltimore, Maryland, United States.
Lead abatement includes lead-based paint abatement activities, such as inspections, risk assessments, as well as removal. Lead abatement must be performed by educated, certified professionals with proper safety protocols to limit lead exposure. The goal is to permanently eliminate lead-based paint hazards, such as serious permanent and irreversible health damage due to lead poisoning in children. This is especially important in home environments and in any facility with frequent visitation by children, particularly those built before 1978.
Open Philanthropy is a research and grantmaking foundation that makes grants based on the principles of effective altruism. It was founded as a partnership between GiveWell and Good Ventures. Its current chief executive officer is Alexander Berger, and its main funders are Cari Tuna and Dustin Moskovitz. Moskovitz says that their wealth, worth $16 billion, "belongs to the world. We intend not to have much when we die."
Lead abatement is an activity to reduce levels of lead, particularly in the home environment, generally to permanently eliminate lead-based paint hazards, in order to reduce or eliminate incidents of lead poisoning.
After decades of increasing crime across the industrialised world, crime rates started to decline sharply in the 1990s, a trend that continued into the new millennium. Many explanations have been proposed, including situational crime prevention and interactions between many other factors with complex, multifactorial causation.
