Arsenic in Drinking Water: Increased Risk of Respiratory Infections and Lung Damage Following Fetal Exposure
By Roberta Attanasio Odorless and tasteless, arsenic lurks everywhere – in rice and in chicken breasts, in apple juice and in drinking water. It’s all around, but not in amounts sufficient to cause acute (short-term) poisoning. On the other hand, chronic (long-term) exposure to lower arsenic doses occurs way too often, and may lead to cardiovascular disease, diabetes, cancers and other human disorders. Contamination of drinking water by arsenic is a global health threat. Presence of arsenic in groundwater is largely the result of minerals dissolving from weathered rocks and soils. In addition, arsenic enters the drinking water supply because of runoff from orchards, electronics production waste or other industrial…

Food Waste Harms Climate, Water, Land and Biodiversity
By The Editors The Food and Agriculture Organization of the United Nations (FAO) released a few days ago a report detailing the first study to analyze the impacts of global food wastage from an environmental perspective, looking specifically at its consequences for the climate, water and land use, and biodiversity. Key facts and figures from the report are: The global volume of food wastage is estimated at 1.6 billion tonnes of “primary product equivalents.” Total food wastage for the edible part of this amounts to 1.3 billion tonnes. Food wastage’s carbon footprint is estimated at 3.3 billion tonnes of CO2 equivalent of GHG released into the atmosphere per year. The total…

Global Threats: The Spread of Crop Pests
By Roberta Attanasio One of the major global threats to food security is the current spread of crop pests, unintentionally moved by human activity across world regions at unprecedented rates. Crop pests include viroids, viruses, bacteria, oomycetes, fungi, nematodes, and insects. In the past, this spread was limited by physical barriers such as mountains, seas and deserts. However, such natural limits are now bypassed because of the rapid increase in international and intercontinental agricultural trade. To date, more than 12,000 alien species have been documented in Europe by DAISIE (Delivering Alien Invasive Species Inventory for Europe), a unique three-year research project involving more than 100 European scientists and funded by…

What Are Endocrine Disruptors?
By Roberta Attanasio According to the International Programme on Chemical Safety, World Health Organization (WHO) (2002), an endocrine disruptor is an exogenous substance or mixture that alters function(s) of the endocrine system and consequently causes adverse health effects in an intact organism, or its progeny, or (sub) populations. This year, a group of experts convened by the United Nations Environment Programme (UNEP) and WHO defined the growing impact of hormone disruptors on human health problems a “global threat“. What is the endocrine system? The endocrine system is one of the communication systems of our body and is found in all mammals, birds, fish, and many other types of living organisms. It’s made up of…

Do Sea Turtles Eat Plastic Marine Debris? Yes!
By The Editors Floating marine debris accumulates in five main oceanic gyres. These debris accumulations consist mostly of plastics and are called great garbage patches. In recognition of the global threat posed by the great garbage patches, the United Nations Educational, Scientific and Cultural Organization (UNESCO) has recently granted them a symbolic State status, and officially recognized the Garbage Patch State. Marine debris gathers in drift lines and convergence zones, which are also important feeding areas for many oceanic species, including sea turtles. Now, results from an analysis of global research data from the past 25 years show that green and leatherback turtles are eating more plastic than ever before. The analysis…

Benzene, Leukemia and Lymphoma
By Roberta Attanasio It’s said to have a sweet smell, or a gasoline-like odor. It’s mostly in the air, and sometime in the water and soil. It’s found all around the world. It’s in cigarette smoke and gasoline vapors. It’s a known human carcinogen – a substance known to cause cancer. It’s benzene. Its target organ is the bone marrow, the soft spongy tissue that lies within the hollow interior of long bones and produces all types of blood cells. The Agency for Toxic Substances and Disease Registry (U.S. Department of Health and Human Services) in the “Toxicological Profile for Benzene” states: “Everyone is exposed to a small amount of…

Arsenic in Rice: Links to Genetic Damage
By The Editors Rice is a staple food for over 3 billion people worldwide. Unfortunately, rice contaminated with arsenic can be found in several regions of our planet. Although serious concerns have been raised in the past few years over the consumption of rice tainted with high levels of arsenic, there was no direct proof of its harmful effects on human populations. Now, results from a new study indicate that staple consumption of cooked rice containing high levels of arsenic leads to genotoxic damage. Arsenic, one of the heavy metals, is a chemical element normally present in water, air and soil. It is released from volcanoes and from the erosion…

The Global Threat of Substandard and Falsified Medicines
By The Editors Treatment with poor quality medicines — substandard and falsified (fake) medicines — is a significant cause of harm to human populations worldwide. According to a report released on February 13, 2013, by the Institute of Medicine of the National Academies “Falsified and substandard medicines provide little protection from disease and, worse, can expose consumers to major harm. Bad drugs pose potential threats around the world, but the nature of the risk varies by country, with higher risk in countries with minimal or non-existent regulatory oversight. While developed countries are not immune, – negligent production at a Massachusetts compounding pharmacy killed 44 people from September 2012 to January…

The Worldwide Obesity Epidemic: Links to Bisphenol A
By The Editors In a previous post, we discussed globesity – the escalating global epidemic of overweight and obesity – and said that controlling globesity requires a variety of approaches, including the understanding of the association between obesity and exposure to environmental pollutants. There are many widespread environmental pollutants that may be contributing to the development of obesity. One of these pollutants is bisphenol A (BPA). In 2012, a study published in the Journal of the American Medical Association indicated that urine BPA is associated with obesity in children and adolescents. Now, results from a study published in the scientific journal PLOS One show that high levels of exposure to BPA…

2013 World Day to Combat Desertification: Today, June 17
By The Editors The theme of the 2013 World Day to Combat Desertification is drought and water scarcity. Freshwater is valuable. Of all the water on Earth, only 2.5 per cent is freshwater. And of all this freshwater, the total usable supply for ecosystems and humans is less than 1 per cent. When demand for water exceeds available supply, it results in water scarcity. This is why the World Economic Forum, in their Global Risk Report 2013, suggests that decreasing water supply is among the top five risks, both by likelihood and impact, that humanity faces over the next ten years. Increasing water scarcity and drought, in part as a result of climate change, will…
