…And now breast cancer?

There has been an intense debate over the possible link between breast cancer and air pollution. FIGO- the International Federation of Gynecology and Obstetrics highlighted the discovery of a link between air pollution and breast cancer following an article published in the Breast Cancer Journal on the results of research conducted by the University of Florida. This was reported by mainstream media as an alarming call to women living in areas with high air pollution.

Do not panic!

But there is no need to panic, it’s very important to be cautious with scientific results. In fact, many organizations like Cancer Research-UK, BreastCancer and others jumped to clarify that finding a link does not mean that air pollution causes breast cancer. Two things can be highly correlated without implying causation.

We know and we’ve talked about how pervasive air pollution is in our bodies, affecting our lungs, circulation, diabetes, skin and many more. The link between air pollution and lung cancer is very well researched, many research teams have worked on this subject for decades and have found how it happens and why. All the other links of air pollution to diseases are still in the very beginning of compiling research results and while it is one thing to link air pollution with skin problems, it is another step entirely to link it with a life-threatening disease like breast cancer.

Be cautious and understand the risks

We should not panic, but we should know the extent of current research on this matter. The latest research was conducted by the University of Florida, US, and looked at the link between breast density and air pollution. They found that women living in areas with high pollution had denser breast tissue. Women with dense breast tissue are up to six times more likely to develop some form of breast cancer.

In 2010, another study by the Research Institute of the MUHC, McGill University and Université de Montreal also showed a link. This study mapped air pollution against breast cancer patients and found that women living near areas with higher levels of pollution were twice as likely to develop breast cancer than the rest. However, Dr Goldberg, a researcher at The RI MUHC said:

“For example, we don’t know how much the women in the study were exposed to pollution while at home or at work, because that would depend on their daily patterns of activity, how much time they spend outdoors and so on”

In the case of this study, what is interesting is that the motivation to study the link between air pollution and breast cancer was to try to understand why cancer rates were going up in general / in these particular high pollution areas. The results showed that it could be air pollution but it may well be some other factor that the study could not control. In fact, the researchers called for more research on this subject and more research on the biological explanation behind this possible link.

Before more scientific evidence is gathered, we should make it a habit to know the quality of the air we breathe and take actions to improve the quality of the air we are exposed to, both indoors and outdoors!

Key steps to ensure office safety

Be air safe in your business

Around the world the pandemic has taken many forms. Some are working from home while others have to work in their offices. Although offices may have less people to ensure social distancing, managers and office space administrators should still take crucial steps to protect their staff. The past months of increased information about how COVID-19 spreads silently, has opened our eyes about the relevance of clean air and social practices in protecting us.

Although, outdoors is the ideal place to gather for safety purposes, offices, and shops can also minimize risk and have employees back in business with their safety as their first priority.

The following steps require to re-think the office with airflow safety in mind.  We need to re-think the way we use office space and even office supplies. Understanding that clean air and clean surfaces are the ultimate goal to staff safety. A new type of health and safety plan is required focusing on: 1) infrastructure maintenance, 2) re-thinking the way we use the space, and 3) ensuring all staff members are involved in the process and understand the need for a change in the way we work and the way we safely socialize.

Start by analyzing the infrastructure and how your devices can ensure the air in the premises is safe. The Heating, Ventilation and Air Conditioning (HVAC) system needs to have the appropriate filters and they should be maintained regularly. Preferably HEPA filters should be used. If possible, outdoor air circulation should be increased; and airflow supply should be re-examined. Similarly, exhaust fans in restrooms are to be checked for performance and encourage their use at all times. This should be coupled with enhancing cleaning and disinfection at all times. Have a close look at the quality of the indoor air, it will make a difference.

Then move to conduct a hazard assessment with the COVID-19 thinking cap. Identifying areas where COVID 19 transmission could happen and how to change them. For example, the meeting rooms, cafeteria, break rooms, waiting areas and many more. This will result in necessary modifications of workstation distancing, or the use of shields to physically separate employees in all areas.  And, wherever physical barriers are not possible, visual cues on the floor can help employees distance themselves. Even shifts staggering will be crucial. Also, re-think best options for high-touch communal items such as coffee pot, microwave etc.

Last but not least, develop a communication plan to adequately convey health safety messages and changes in space usage to employees. Set a protocol for employees to know when to stay home, how to work from home when they have symptoms, or when a family member has symptoms. And if possible, provide that flexibility to work from home. Use signage to remind people of key actions to reduce transmission.

Keep in mind, indoor air quality is key to employees’ health and safety!

Smells clean…but it may be harmful!

Our quest for cleaner and cleaner living environments with no traces of bacteria leads us to use cleaning products advertised as effectively eliminating 99% of bacteria especially in our kitchens and bathrooms. Cleaning products have been progressively improved with fragrances that we associate with cleanliness but are we being fooled!?

Many of these aromas are created through the use of enzymes that are known to be allergens. The smell that we associate with cleanliness is often the evidence that there are volatile organic compounds (VOC) in the product which give off different types of gasses. Fragrances and many other product features are created through the use of chemicals that are often harmful to our health and environment. Moth repellents, air freshners, aerosol sprays, degreasers, dry cleaning fluids and cleaning products / detergents are all toxic if ingested, but can also enter our body through touch and smell.

How our cleaning products may affect us will depend on many factors including how long we are exposed to it, the level of exposure and the nature of the VOC or chemical in use. In addition, we must not forget that many of these products are not eliminated by the body and just keep accumulating until a problem arises. Many of their ingredients fall into three harmful categories: carcinogens which may cause or promote cancer’s growth; endocrine disruptors which mimic hormones and affect reproduction, development, growth and behaviour; and neurotoxins which affect brain activity.

TYPE of chemicals that are harmful:
  • Pesticides: cleaning products are not seen as pesticides but they are. They are carcinogens and endocrine disruptors that are difficult to eliminate from the body once ingested.
  • APEs: help cleaning solutions easily spread in a surface and known to be endocrine disruptors.
  • Organoclorides: endocrine disruptors.
  • Phtalates: endocrine disruptors, possible carcinogens and are currently not required to be disclosed as ingredients.
Common chemicals in cleaning products:
  • Perchloroethylene, a known carcinogen, is used in dry cleaning agents and degreasers.
  • Styrene is an endochrine disruptor, used in floor waxing products.
  • Formaldehyde is a known carcinogen, used in household antiseptics, medicines, dishwashing liquids, fabric softeners and carpet cleaners.
  • Benzene also carcinogenic is used in detergent and furniture wax.

Without a doubt, those most at risk are children, followed by elderly, asthmatics and those persons with compromised immune systems. We tend to believe that if we ensure these products are out of children’s reach they are safe. However, we seldom think that children are exposed to the ill effects of these products through touch and smell. They crawl on the ground, lick their fingers and as a result have greater contact with surfaces cleaned with these products than Adults. Moreover, any exposure they have has a larger effect in their body because of the ratio between exposure and body size, as well as the fact that their immune system is in a developmental phase.

Surprisingly in many countries, household cleaners are not required to list all their ingredients. This makes it more difficult for consumers to know more about the potential risk.

Healthy TIPS: With a little help from Vitamin B

In a previous blog-post we talked about protecting our health from within and stressed the need to consume vitamin C, E, Beta-carotene and Omega3 which boosts our body’s anti-inflammatory and antioxidant capacity. Research published in the Pharmaceutical Journal is now including Vitamin B in the realm of our must-have nutrients to fight health consequences from air pollution.

Vitamin B essentials

Our bodies need Vitamin B for producing energy through food, growth and cell division, as well as for the proper functioning of the nervous system, arteries, heart and brain. These vitamins can be found in foods such as meats, whole grains, vegetables and nuts – and especially in chickpeas, beef liver, yellowfin tuna, salmon, chicken breast, potatoes and bananas. We need to maintain a good intake of these foods at the same time as facilitating its absorption by decreasing alcohol, coffee and tea consumption. The vitamin B group includes a range of vitamins but the most essential are B12, B6 and Folic acid

Vitamin B and air pollution

Studies had first found that persons with low vitamin B6 and B12 were particularly susceptible to the adverse health effects of air pollution. Now, scientists from the Mailman School of Public Health from Columbia University looked at the possible effect of vitamin B in minimising DNA damage. The study sample size is very small but it is being conducted on people and compares DNA changes in people exposed to PM2.5 against those who were not exposed. And then compares the protective effect of Vitamin B6, B12 and Folic acid (B9).

Dr Jia Zhong from Harvard School of Public Health led the study and found that although the results from such a small sample cannot be conclusive, they do show DNA damage from exposure to PM2.5 and a protective effect from Vitamin B even when the individual is exposed to PM2.5. The sample was small and the vitamin dose used was very high, but the relevance of this finding is that more research can be done to further to understand the correct dosage and if this effect is also experienced among people who are under chronic exposure to air pollution.

As a preventive measure we can make sure we have good vitamin B intake to help our bodies protect us from air pollution

School’s Indoor Air Quality

How often do we think about the air quality in our children’s school, where they spend almost a third of their day?

In cities with poor outdoor air quality, schools usually limit outdoor physical education and break time according to local outdoor air quality readings. But what about the quality of the indoor air?

Let’s think about it for a moment!

Studies have shown that poor air quality in schools increase absenteeism, decrease test scores and compromise staff and student productivity.

When we think of academic excellence we’ll seldom think of structural and maintenance practices that can provide the optimal environment for teachers and students to thrive. Nonetheless, leaky roofs, poor heating, ventilating and air conditioning systems (HVAC), inappropriate use of cleaning products among others can make a difference in academic excellence.

In fact, poor indoor air quality can cause asthma, respiratory infections and allergic diseases which start a spiral of effects from school absenteeism to poor performance.

What is the impact of indoor air quality in schools?

Asthma, respiratory infections and allergic diseases are commonly caused or exacerbated by moisture in HVAC system, microbiological pollutants, animal allergens, nitrogen dioxide or other combustion byproducts, chemicals in cleaning products, low ventilation, formaldehyde, dampness, mold, outdoor pollutants or vehicle exhaust.

Asthma for example is suffered by millions across the world – approximately 1 in every 10 children!  And it is the main reason students skip school in the US. Asthma can be controlled with medications after it occurs but a great deal can be done before it occurs by controlling the environmental triggers, especially in closed environments like schools.

For optimal indoor air quality in schools, we need to:

Indoor and outdoor air pollution: a silent threat

The World Health Organisation estimates that 3.7 million deaths are the result of outdoor air pollution, and 4.3 million deaths are attributable to indoor air pollution. Sadly, our region (Western Pacific) has the highest number of casualties due to air pollution.

Air pollution control is not entirely in the hands of individuals, but controlling exposure to air pollution is.

When legal action meets air quality

A few years ago, a French woman launched a law suit against the French government for failing to protect her from air pollution. More precisely, for ‘culpable incompetence’ by not having a heavy hand against polluters and not taking strong preventive measures. She is asthmatic, 56 years old and a yoga teacher that suffers gravely from every air pollution spike. She is the first plaintiff in France but her lawyer says there are about 30 more in Paris, Lille and Lyon who are planning legal action!

Are law suits the new way to push for better air quality?

In fact, we know of several examples in Europe where legal action is being used to push governments for better air quality. In April 2015, the UK legal NGO ClientEarth won a Supreme Court ruling against the UK government. The ministers were ordered to design a plan to ‘bring pollution down within legal limits as soon as possible’.  The new plan was presented in 2016 but the government was slammed once more by another legal battle won by ClientEarth at the High Court.

“The government’s new plans to tackle air pollution are woefully inadequate and won’t achieve legal limits for years to come,” said ClientEarth lawyer Alan Andrews to The Guardian “The longer they are allowed to dither and delay, the more people will suffer from serious illness or an early death.”

“There is clear consensus that the government’s plans are wholly inadequate to address this public health crisis,” said Kerry McCarthy, Labour’s shadow environment secretary. “It should not take legal action to force the environment secretary to take urgent action and help save lives.”

In September 2016 in Prague, the Vlasta Coalition NGO lodged a law suit against the local ministry’s plan to tackle air pollution. Three individuals have joined the law suit from various parts of the country with their claims. Similarly, The European Commission threatened legal action against France, Germany, Italy, Spain and the UK for failing to protect their citizens from air pollution. ClientEarth is in fact partnering with local NGOs to launch cases across Europe against local and national governments. The first one to appear is legal action against Lombardy – a region in the north of Italy with Milan in the Centre of it.

More data on air pollution and more knowledge about its ill health effects will provide the basis for citizens to demand their rights and for governments to better understand how to manage policies to improve air quality.

The Power of Plants: Cleaning Your Indoor Air Environment

September is here and, in many parts of Asia this month marks the beginning of high pollution days. Beijing, Shanghai, Hong Kong, New Delhi and other cities may experience in the next months higher levels of pollution than during the summer. But no need to panic because there is a lot we can do to improve the air quality inside our homes and keep the indoor pollution at a minimum.

We are usually concerned about the outdoor air pollution, but know little about the air quality in our homes or offices, where we spend most of our time. In fact, modern furnishings, paints, synthetic building materials, cleaning  and cooking materials all off-gass unwanted chemicals that pollute the indoor air and create health problems for us. Those pollutants are commonly benzene, formaldehyde and trichloroethylene, but we can also find airborne biological pollutants, carbon monoxide, nitrogen oxides, pesticides, disinfectants (phenols), and even radon. Our sensitivity to these gases ranges, but they have initial health effects that limit productivity like headaches, nausea, irritation of eyes throat, or nose; allergies, coughing, dry or itchy skin and inability to focus. Prolonged exposure can cause more severe effects.

Today we want to showcase the benefits of certain plants in helping control your indoor air pollution. During the 1980’s NASA and the Associated Landscape Contractors of America researched how plants could clean the air in space stations. The results showed that plants absorb carbon dioxide and release oxygen, some plants even filter volatile organic compounds such as formaldehyde, xylene, benzene, chloroform and trichloroethylene. This study is the base for many other more recent studies in this subject.

In Asia, Kamal Meattle is an incredible advocate for the use of plants to clean your indoor air. He agrees that plants alone will not do the work because of the high quantity required (between 6-8 per person per room), nonetheless only one plant per 100 sq feet will already help substantially.

“There are three easy-to-maintain plants that we use for natural air purification. They are the areca palm, mother-in-law’s tongue and money plant. The areca palm and money plant produce oxygen during the daytime while mother-in-law’s tongue produces oxygen during nighttime. These three common houseplants remove chemical toxins from the indoor air, reduce CO2 levels and enrich it with more oxygen. By keeping these plants, we ensure that there is a constant supply of oxygen in the air.”

Kamal Meattle

Among the 50 plants recommended by researcher Bill Wolverton, who participated in the NASA study, the most common and powerful plants at cleaning the air are:

Areca Palm (Areca lutescens), Mother- in- Law’s Tongue (Sansevieria), Madagascar Dragon Tree (Dracaena Marginata), Bamboo palm (Chamaedorea seifrizii), Corn Plant (Dracaena fragrans), Rubber tree (Ficus elastica), Golden Pothos (Scindapsus aureau, Boston fern (Nephrolepis), Goosefoot Plan (Syngonium podophyllum), Peace lily (Spathiphyllum).

In addition to improving your air quality, plants reduce fatigue and stress, increase productivity, improve the mood, enhance concentration and help with memory. You only need to be more careful if you have pets, because some of these plants may be harmful for them.
