Sperm May Be Harmed by Exposure to BPA, Study Suggests

Sperm May Be Harmed by Exposure to BPA, Study Suggests
ScienceDaily (Aug. 3, 2010) — In one of the first human studies of its kind, researchers have found that urinary concentrations of the controversial chemical Bisphenol A, or BPA, may be related to decreased sperm quality and sperm concentration.
However, the researchers are quick to point out that these results are preliminary and more study is needed. Several studies have documented adverse effects of BPA on semen in rodents, but none are known to have reported similar relationships in humans.
BPA is a common chemical that's stirred much controversy in the media lately over its safety. Critics say that BPA mimics the body's own hormones and may lead to negative health effects. BPA is most commonly used to make plastics and epoxy resins used in food and beverage cans, and people are exposed primarily through diet, although other routes are possible. More than 6 billion pounds of BPA are produced annually.
The new study, published online in the journal Reproductive Toxicology, suggests that more research should focus on BPA and health effects in adults, says John Meeker, assistant professor of Environmental Health Sciences at the University of Michigan School of Public Health.
Meeker is the lead author on the study, along with Russ Hauser, the Frederick Lee Hisaw Professor of Reproductive Physiology at Harvard School of Public Health. Colleagues at Massachusetts General Hospital and the U.S. Centers for Disease Control and Prevention also contributed to the research.
"Much of the focus for BPA is on the exposures in utero or in early life, which is of course extremely important, but this suggests exposure may also be a concern for adults," Meeker said. "Research should focus on impacts of exposure throughout multiple life stages."
Meeker and Hauser recruited 190 men through a fertility clinic. All gave spot urine samples and sperm samples the same day. Subsequently, 78 of the men gave one or two additional urine samples a month apart. Researchers detected BPA in 89 percent of the urine samples.
Researchers measured sperm concentration, sperm motility, sperm shape and DNA damage in the sperm cell.
"We found that if we compare somebody in the top quartile of exposure with the lowest quartile of exposure, sperm concentration was on average about 23 percent lower in men with the highest BPA," Meeker said.
Results also suggested a 10 percent increase in sperm DNA damage.
The results are consistent with a previous study by Meeker and Hauser suggesting that certain hormones, specifically FSH (follicle-stimulating hormone) and Inhibin B, are elevated or decreased in relation to BPA, respectively, a pattern consistent with low sperm production and development.
Meeker stressed that further study is necessary due to the study's relatively small sample size and design.
"The study from which these data came is currently in progress," Hauser said. "With a larger sample size and enhanced study design, we will be able to more definitively investigate this preliminary association in the near future."

Media Release - DEC allows toxic fire pollution to escape into the environment

The Alliance for a Clean Environment has today slammed the DEC for failing to clean up the Waste Control Fire site and allowing pollution to escape into the environment.

Eight years have passed since the Bellevue fire disaster that released thousands of kilograms of toxic waste into the atmosphere, groundwater and soil and affected the health of surrounding residents, businesses, fire fighters and post emergency cleanup personnel.

Numerous investigations, spanning eight years have not resulted in any remediation options. ACE representatives were outraged to hear that the DEC is no closer to a cleanup of the site than it was 7 years ago.

“What is very clear is that the DEC are utilising a method known as ‘Natural Attenuation’ so as to reduce the amount of contamination over time and therefore reduce the cleanup costs. Miraculously, the contamination has been reduced from 50 000 cubic metres to a mere 2000 cubic metres according to Golder Associates. It really is a case of the disappearing pollution…but far from actually disappearing - it is migrating into the environment, the atmosphere and ultimately into the ecosystems and bodies of the surrounding community”, exclaimed Jane Bremmer spokesperson for ACE.

“The Waste Control disaster represents the worst case management of a contaminated site and associated social impacts in WA’s history. The victims of this disaster have received no compensation, no health check follow ups and have been left with the legacy of this toxic time-bomb in their community, slowly leaching into the environment and atmosphere for the last 8 years.

Claims by the Contaminated Sites Manager, Kerry Laszig, that the waste degrades into “safe gases” have no credibility when it is well documented in many scientific reports that this material releases highly toxic vapours and degrades to chemicals such as vinyl chloride. The University of Minnesota states“…(TCE) are suspected carcinogens and some of the most abundant environmental pollutants of groundwater in the United States. In some groundwater, they undergo reductive dechlorination catalyzed by anaerobic bacteria that yields vinyl chloride, a potent human carcinogen.”.

In fact the US Agency for Toxic Substances and Disease Registry (ATSDR) states… “If PCE (which is also known as TCE and known to be at Waste Control in large amounts) pollutes surface water or surface soil, it will mostly evaporate into the air and disperse. PCE can readily travel through soil with little impedance and enter into groundwater, and… “The Department of Health and Human Services (DHHS) has determined that tetrachloroethylene may reasonably be anticipated to be a carcinogen. Tetrachloroethylene has been shown to cause liver tumors in mice and kidney tumors in male rats.”

The DEC’s continued failure to respond to this slow disaster appears to be consistent with a lack of expertise in environmental health protection and a more worrying attitude towards the community, environment and their role in regulating industry and preventing pollution. This is of course not surprising news given the identification of these same issues in three WA parliamentary inquiries. (ie Alcoa, Waste Control and Esperance)

Chemical Free Kids

What is Chemical Free Parenting?

’Our children will ask.... What were our parents thinking? Why did they produce toxic chemicals and then put them in and on our bodies? Were they so arrogant to think that our bodies would not be affected?’
– Dr Sarah Lantz (PhD)

For many parents, the importance of keeping our children as pure and toxic free as possible is critical. But it's not so easy to do these days. There are over 100,000 synthetic chemicals available on the market with over 1500 new chemicals being produced annually. Over half of these chemicals have never been tested for their toxicity on the human body.

These chemicals, used extensively in manufacturing and emitted into the environment, accumulate in the food chain and end up in our bones, blood, fat, urine, and breast milk, ovaries, and sperm. They are then passed onto the developing child across the placenta, through breast milk, in food and water, or the creams, lotions, soaps and personal care products we lather and bathe them in.

Chemical Free parenting is about conscious parenting. Because we initially make the choices about what our children consume, how they are washed, what they sleep in, what medications and drugs, if any, we recommend, and where they spend most of their time, we need to know about these chemicals and be able to identify them. Chemical Free Kids: Raising healthy children in a Toxic World , is a community program and book about these chemicals and the impact on the bodies and health of our kids - how they get into their bodies, the health and behavioural problems they cause, why kids are particularly exposed to chemicals and what we, as a society, industry, and parents, can do about it.

The intention of this program is to unconceal to the public the hidden impact of chemicals in the environment on the health and wellbeing of our kids and young people and to give parents, care givers, teachers and health practitioners of kids and young people more control over what enters their kids’ bodies.
The program consists of a number of vehicles that serve to bring awareness about the issue of environmental chemicals and their hidden impact on human health:

• A book titled CHEMICAL FREE KIDS:RAISING HEALTHY CHILDREN IN A TOXIC WORLD
• A national seminar speaking tour
• Workshops to be held throughout in both capital cities and regional centres across Australia

Recycled sewerage plan for WA taps

The West Australian carried an article on Saturday (28/2/09) that outlined plans to add treated sewerage wastewater to Perth’s drinking water supplies. The Water Corporation has released a draft policy, Water Forever: Directions for Our Water Future, which is open for public comment until the 15^th May 2009.

Last Wednesday (25^th February 2009), Jane Bremmer (Vice Chair of the ACE) delivered a presentation to the Conservation Council of WA's "Environment Matters - Wastewater Recycling - the Future of Water in WA ?" forum. The presentation, called "Muddying the Waters" raised concerns over the use of reclaimed water for drinking water or groundwater recharge, in particular the fate of Endocrine Disrupting Chemicals (EDC) and Pharmaceutical and Personal Care Products (PPCP) that are known to survive even advanced water treatment processes. A copy of the presentation can be found here.

ALCOA let off DEC Hook - Sunday Times 15/2/09

The Sunday Times article, in which the State’s Ombudsman urged WA’s “environmental watchdog” to lift its game when dealing with complaints about pollution. The Ombudsman found that the DEC failed to properly respond to reports of odours, fumes, dust and health problems.

CAPS spokesperson, Vince Puccio, echoed the phrases that are so often encountered by community groups “Complaints were going from one office to another and none was being heard or addresses” and “the community felt it was fighting a losing battle because no one was listening to them.”

ACE’s own, Ron Jones, commented that “The way the department handles complaints is typical not just of ALCOA, but of many industries where complaints are made”.

Perhaps it is time for a competition:

“Try and list as many inquiries, investigations, articles etc where the DEC (or previous incarnations) where the department has been found lacking . . .”

Submission on Municipal Waste Management in WA

The Alliance for a Clean Environment has made a submission to the Legislative Council’s Standing Committee on Environment and Public Affairs for their Inquiry into Municipal Waste Management in Western Australia.

The Inquiry terms of reference are as follows:

Considering the ongoing community concerns about the odour emanating from the Regional Resource Recovery Centre in Canning Vale (RRRC) the Committee resolves to use the issues surrounding the RRRC as an illustrative practical case study to conduct a broader inquiry into

1) Current municipal waste management practice and methods in Western Australia, and in particular:

(a) The function, effectiveness and efficiency of rural and Metropolitan Regional Councils with respect to the management of waste; and

(b) The role of the Waste Authority under the Waste Avoidance and Resource Recovery Act 2007 in municipal waste management.

2) Resource recovery technologies; and

3) Any other relevant matter.

The ACE submission focussed on a number of issues, including the opposition to thermal processes (incineration, gasification, pyrolysis, and “waste to energy” plants) and landfills, and called for the establishment of suitable technology and siting criteria for proposed MSW treatment facilities.

ACE is generally supportive of composting processes, with the proviso that the siting and technology criteria are suitable, there is sufficient source separation, there is industry support for the recycling and reprocessing of recyclables, adequate regulation of facilities, ongoing research into methods of waste reduction, and management of problematic wastes.

ACE also called for the establishment of a classification system for composts that are derived from MSW or sewerage sludges, the fast tracked introduction of Health Impact Assessments, the development of an odour impact assessment guideline and regulatory regime, and called for the development of a new assessment, licencing, monitoring and enforcement framework that will work to address previous regulatory failures.

Finally, ACE called for the “3C” Process to be restarted so that it can fulfil its goal of establishing new and better hazardous waste treatment facilities in WA.

Full copies of the submission can be made available on request, and will be posted on the ACE website (www.ace-wa.org)

Petition – Regulation of transport, management, handling and export of mining products in West Australian ports

In Western Australia over the last 10 years, several major environmental health disasters have brought the public’s attention and concern to the failings of our government’s ability to safely regulate industry and the transport, handling and export of hazardous and dangerous materials in our state.

WA prides itself on the major contribution it makes to the global economy through the mining and extractive industries. The city of Perth clearly exhibits the wealth and culture generated by this industrial based economy. Yet such industry’s come with high environment and health costs that are rarely acknowledged or considered within the cost benefit analysis and approvals processes by both industry and government.

There is growing public concern that WA does not have specific environmental health protection laws nor recognition within existing legislation to protect the most vulnerable in society, our children, the elderly and those with compromised immune systems and our indigenous citizens who are disproportionately impacted by mining and heavy industry development in our regional areas.

Since 2001 there have been 3 major parliamentary inquiries over significant industrial related environmental health disasters.

The Waste Control Fire Inquiry (2001), which stated…

“Chemical Storage at the Waste Control Site:
• From the time of the first regulatory agency inspection did not comply with regulations; and
• At no time was in complete compliance with either the DEP or DME licence conditions.
(Finding 12. p29, Bellevue Hazardous Waste Fire Inquiry 2002)

The Cockburn Cement ministerially initiated independent audit (2002), which found that there were deficiencies in the Department of Environmental Protection’s management and regulation of the Munster site.

The Alcoa Inquiry (2004) which stated….

Inquiry Rec 20: The Committee recommends that the Government, as a matter of priority, develop and finalise air emission guidelines specific to WA and that these should include VOC’s and standards for multiple chemical exposure.


And the recent Inquiry into the lead impacts at Esperance (2007) which stated…

“DEC staff and resources assigned to approving projects vastly outweighs the staff and resources assigned to post approval compliance monitoring and auditing.”

• There were critical failures by the EPA, the DEC and Magellan Metals P/L to implement DoH recommendations and advice in the environmental approval processes associated with the events that are the subject of this inquiry (finding 23)

• The committee believes that the DEC, Esperance Port Authority and Magellan metals P/L, all failed substantially in meeting their responsibilities regarding the effectiveness of dust management, monitoring and reporting lead levels in the Esperance area. (finding 55)

• Critical advice about the Esperance Port Authority’s environmental licence and dust monitoring regime received from the DoH in Sep 2005 was not followed up the Department of Environment until Feb 2007.(finding 149)

Of particular concern to the public is the lack of action by our government to enact recommendations that have been made as far back as the Waste Control Inquiry of 2001 and again in later inquiries. For example….

(Bellevue Fire report 2002) Rec 8. The EIA process as contained in the EP Act 1986 be expanded to:
Incorporate a health impacts assessment where appropriate; and
Involve the Heath Department of WA in the process of the health impact assessment.

(Alcoa Refinery at Wagerup Inquiry 2004) Rec 29. The Committee recommends that the Government review legislation and make necessary amendments to ensure that the Dep’t of Health has a formal role in advising the Environmental Protection Authority in relation to the assessment of projects that may impact on public health.

(Inquiry into the Cause and Extent of Lead Pollution in the Esperance Area 2007)
Rec 10. The Committee recommends that there be a legislative requirement for the Department of Health to conduct a health impact assessment as part of the Environmental Assessment Process.

It is clear that our current government aims to fast track industrial and mining approval processes in WA enabling more mining and industrial activity through our towns, ports and environments. The increased risks this will bring to the health of our population and protection of our environment needs urgent recognition. The potential for uranium mining and other high risk proposals to gain approval in WA is becoming a reality. Therefore it is urgent and timely for our government to investigate the adequacy of our current regulatory framework to safely protect our workers, public health and environment at all WA Ports and along transport routes where the handling management, transport and export of hazardous and dangerous materials are carried.

It is unbelievable that with such wealth as is generated in this state from the heavy, extractive and mining industries that some of this wealth is not directed to ensure the protection of our environment, public health and future generations.

Please consider signing this petition and disseminating it widely. ACE plans to present this petition to Parliament at the end of March 2009. Please ensure that you post all completed and partly completed petitions to ACE at PO Box 254, Guildford WA 6935 before the 31st March 2009.
