This is our main data entry on plastics, with a particular focus on its pollution of the environment. However, rapid growth in global plastic production was not realized until the s. Over the next 65 years, annual production of plastics increased nearly fold to million tonnes in For context, this is roughly equivalent to the mass of two-thirds of the world population. This is crucial, not only in understanding the scale of the problem but in implementing the most effective interventions for reduction. The data and visualizations which follow in this entry provide this overview step-by-step. This overview is summarized in the figure.

Water pollution is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks or uses or lives in it. When humans drink polluted water it often has serious effects on their health. Water pollution can also make water unsuited for the desired use. There are several classes of water pollutants. The first are disease-causing agents. These are bacteria, viruses, protozoa and parasitic worms that enter sewage systems and untreated waste.

A second category of water pollutants is oxygen-demanding wastes; wastes that can be decomposed by oxygen-requiring bacteria.


NOAA provides scientific expertise, data, tools, training, and assistance to help people respond to oil and chemical spills. An oiled rock along the Mississippi River shoreline near New Orleans following a fuel oil spill in April Each year, there are thousands of oil and chemical spills in coastal waters around the nation.

These spills range from small ship collisions to fuel transfer mishaps to massive spill events like the BP Deepwater Horizon oil spill. The release of oil and chemicals into our coastal waterways can kill wildlife, destroy habitat, and contaminate critical resources in the food chain.

Water pollution, toxic chemical use and textile waste: fast fashion comes at a huge cost to the environment. But before you head out into the January sales for those irresistible deals, spare a thought for the impact of fast fashion on the environment. Fast fashion focuses on speed and low costs in order to deliver frequent new collections inspired by catwalk looks or celebrity styles. But it is particularly bad for the environment, as pressure to reduce cost and the time it takes to get a product from design to shop floor means that environmental corners are more likely to be cut.

Criticisms of fast fashion include its negative environmental impact, water pollution, the use of toxic chemicals and increasing levels of textile waste. Vibrant colours, prints and fabric finishes are appealing features of fashion garments, but many of these are achieved with toxic chemicals. Textile dyeing is the second largest polluter of clean water globally, after agriculture. Many of these are banned or strictly regulated in various countries because they are toxic, bio-accumulative meaning the substance builds up in an organism faster than the organism can excrete or metabolise it , disruptive to hormones and carcinogenic.

Polyester is the most popular fabric used for fashion. But when polyester garments are washed in domestic washing machines, they shed microfibres that add to the increasing levels of plastic in our oceans. These microfibres are minute and can easily pass through sewage and wastewater treatment plants into our waterways, but because they do not biodegrade, they represent a serious threat to aquatic life.

Small creatures such as plankton eat the microfibres, which then make their way up the food chain to fish and shellfish eaten by humans. Cotton growing requires high levels of water and pesticides to prevent crop failure, which can be problematic in developing countries that may lack sufficient investment and be at risk of drought.

Taking the necessary measures to maintain employees’ safety, we continue to operate and accept samples for analysis. There are two techniques in measuring radiocarbon in samples—through radiometric dating and by Accelerator Mass Spectrometry AMS. The two techniques are used primarily in determining carbon 14 content of archaeological artifacts and geological samples.

On September 19, , sixty thousand people gathered in Tokyo to protest against nuclear power and radiation pollution after reactor meltdowns at the Fukushima Daiichi Nuclear Power Plant. Their protest evoked memories of the s when Japan was among the most polluted locations on the planet with hazardous levels of air, water, and ground contamination. Observers at the time described the country as a polluters’ paradise and advised tourists to pack a gas mask.

By the early s, however, the Japanese had addressed many their thorniest pollution problems and the country possessed some of the strictest regulatory standards in the world. In this article I analyze the activities of an influential group of natural and social scientists, the Pollution Research Committee, which spearheaded the struggle against pollution. I make two claims.

First, on the positive side, the committee played a decisive role in Japan’s pollution turnaround through its field research, pollution victim advocacy, and extensive international activities. But, second, the reactive victim-centered environmental agenda of the committee and other contemporary groups never developed into a preventive movement capable of identifying and scrutinizing potential forms of pollution such as radiation.

Find Out. Multiple changes in the structure of the food system and agriculture raise new opportunities and challenges for the agricultural sector. In the developing world, these changes started in Asia and Latin America, and are rapidly emerging in Africa. Urbanization and increased urban demand for food, fiber, and fuel present new market opportunities for farmers, entrepreneurs, and agribusiness in the developing world. Growing concerns over climate change, pollution and food safety are reflected in increasing consumer demand for environmental services from agriculture, electricity and fuel from biomass, and improved food quality from the food and agricultural sector.

Failure to adapt to these changes may cause the rural sector and smallholder farmers to fall further behind.

At its deepest point Lake Erie is feet 64 metres deep. These jurisdictions divide the surface area of the lake with water boundaries. The lake was named by the Erie people , a Native American people who lived along its southern shore. The tribal name “erie” is a shortened form of the Iroquoian word erielhonan , meaning long tail. The main natural outflow from the lake is via the Niagara River , which provides hydroelectric power to Canada and the U.

Lake Erie’s environmental health has been an ongoing concern for decades, with issues such as overfishing , pollution , algae blooms , and eutrophication generating headlines. Lake Erie Because it is the shallowest, it is also the warmest of the Great Lakes, [18] and in this almost became a problem for two nuclear power plants which require cool lake water to keep their reactors cool.
