Fireworks cause environmental pollution
WASHINGTON, May 29 (UPI) -- U.S. government scientists say Fourth of July fireworks displays often held over lakes and other bodies of water can pollute the water with perchlorate.
The U. S. Environmental Protection Agency's Richard Wilkin and colleagues, who conducted the research, note concerns have arisen over the effects of environmental perchlorate on human health and wildlife. Sources of perchlorate range from lightening and certain fertilizers to the perchlorate compounds in rocket fuel and explosives.
Scientists long suspected community fireworks displays were another source, but few studies had been done on the topic.
Wilkin's group has now established fireworks displays as a source of perchlorate contamination by analyzing water in an Oklahoma lake before and after fireworks displays in 2004, 2005 and 2006. Within 14 hours after the fireworks, perchlorate levels rose 24 to 1,028 times above background levels. Levels peaked about 24 hours after the display, and then decreased to the pre-fireworks background within 20- to 80 days.
The study is detailed in the June 1 issue of the journal Environmental Science & Technology.

As an Asthma sufferer I am compelled to add the following:
http://www.stop-fireworks.org/fireworks_asthma.htm
In connection with fireworks one mostly thinks first of the numerous explosion consequences and burns as well as of eye and ear damages and hand injuries. And one often forgets another important aspect: The smoke of fireworks consists mainly of fine toxic dusts (particulate matter, PM10) that easily enter the lungs and represents a real danger for those already sick as well as for the healthy. In addition, fireworks let-offs are the result of explosions releasing a mixture of chemical components. In a fireworks burn-down a number of chemical reactions take place among the particles involved (so-called conversion of matter); at the same time a large number of new substances are generated, substances of largely unknown composition and toxicity.
Emission measurements, which attest increased contents of pyrotechnic elements in fine dust (PM10), are available from the USA [Perry], the Netherlands [Noordijk] and Switzerland [BRISKA]. It was shown in Basel that e.g. the concentration of potassium on August 1 was approximately 100 times higher than before or after that date. While on ordinary days potassium was mainly contained in the coarse particles, on August 1 potassium was attested mainly in small particles. Emissions of fireworks cumulate therefore mainly in small particles.
In the Federal State of Washington the metal contents measured in fine dust PM2.5 on 4th July 1990 (American national holiday) showed that the concentrations of the characteristic content materials of fireworks, such as strontium and barium, rose around 20 respectively 50 times in the daily average.
During the Stockholm Water Festival in 1996, air pollutant levels were measured before and after the fireworks display. Levels of airborne arsenic were found to be twice as normal, while levels of mercury, cadmium, lead, copper, zinc and chromium were 4 to 5 times higher than normal.
The Swiss Agency for the Environment, Forests and Landscape (SAEFL) concludes in its study "Fireworks":
Ø Investigations in the country and abroad show that increased metal contents in the air on special holidays have to be attributed to fireworks.
Ø Fine dust originating from fireworks differ in their composition substantially from types of dust from other sources of emission. The health risks are only insufficiently investigated.
Emissions of fireworks are a well-known cause of health impairments. Particularly affected are persons who suffer from illnesses of the respiratory system, multiple chemical sensitivity (MCS) as well as heart and circulation disturbances.
The article "New Year's Eve with protective mask. Some humans suffer heavily under New Year's Eve and 1st August fireworks: The poisonous smoke leads to dizziness, heart disturbances and asthma attacks." describes the health impairments induced by the poisonous chemicals of fireworks by some people with MCS and asthmatic (à please read also http://www.stop-fireworks.org/injured_persons.htm where people with MCS and/or asthma describe in an impressive way their health problems caused by the poisonous chemical-mix of fireworks.). Nevertheless people extremely hurt by the chemical-mix of fireworks who must stay behind closed windows and in addition have to wear a paper or gauze mask to protect themselves are not taken seriously by their surroundings, by authorities, nor by a majority of physicians unfortunately.
Other countries take the situation essentially more seriously (à different newspaper articles and scientific articles). E.g. Gregg Kishaba, the "director of asthma education" of the American Lung Association of Hawaii recommends among other things: ("Fireworks sales expected to be lower for new Year's - Fewer retailers have obtained licenses, and fewer people are expected to buy them", 26.12.2002, http://starbulletin.com/2002/12/26/news/story3.html):
Ø Stay indoors with windows and doors closed and use an air conditioner or air purifier with a good filter during the heaviest fireworks celebration.
Ø Wear a paper or gauze mask to decrease smoke inhalation.
(and in addition The Lung Association offers free dust respirators and of coordinates kamaaina rates at 13 hotels to at-risk resident.)
All of these facts have long been well-known to the authorities; for years citizens have complained again and again. The complaints are addressed primarily to the Swiss Agency for the Environment, Forests and Landscape (SAEFL), the central office for explosives and pyrotechnics in the Federal Office for Police and to various police stations.
It is not by chance that the SAEFL writes in its report "ENVIRONMENTAL MATERIALS NR. 140, environmentally hazardous materials, fireworks: Impact on the environment and safety aspects 2001": <
> (P. 9) and <> (P. 12) as well as <> (P. 13)
Nevertheless the report - surprisingly - concludes <> and that there exists <>.
Although some paragraphs covering health protection of its people/citizens can be found in different Swiss laws, authorities, politicians, physicians etc. neglect in an incomprehensible way that part of the population with the heaviest health impairments caused by poisonous chemical-mix from fireworks.
The majority of the remaining population does not understand why the specifically poisonous chemical-mix from fireworks leads for more and more humans to heaviest health impairments and, yes, even to a death threat. Information on this subject is very much needed – and could perhaps influence the one or the other to feel responsible towards his/her neighbours and the environment and to renounce - without waiting for additional legal regulations – to letting-off fireworks altogether.
